Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The medical equipment can monitor the physiological sign parameters of the patient, and the monitoring result can be displayed in a mode of graphs such as trend graphs and wave charts. During the continuous monitoring process of the medical device, the graph may change along with the change of the physiological sign condition of the patient. If the medical staff finds that the graph has abnormal change, the medical equipment can be operated to freeze the abnormal graph segment. The frozen image segments can provide data support for subsequent sign anomaly analysis.

The existing medical equipment is provided with an entity freezing key, and if a medical worker finds that the monitoring graph is abnormally fluctuated and is right beside the medical equipment, the medical worker manually presses the freezing key. If the healthcare worker is at a remote location from the medical device, it may be necessary to come to the side of the medical device and trigger the freeze button. The medical device may freeze a graphic segment from the monitored graphic in response to the freeze instruction. However, this freezing method needs to rely on the medical staff to manually operate the medical equipment, and for the medical staff, the operation method is not convenient enough, and the user experience is not good enough.

The invention provides a medical device which can specifically comprise a monitor, a central station and the like. As shown in fig. 1, the medical device may specifically include: adisplay 101, anaudio capture device 102, amemory 103, and aprocessor 104. Theprocessor 104 is connected to thedisplay 101, theaudio capture device 102, and thememory 103.

Adisplay 101 for displaying graphical data of at least one physical sign parameter of the monitored subject.

Wherein, the medical device can monitor one or more sign parameters of the monitored subject and generate the graphic data of the sign parameters. The graphical data may include wave charts, trend charts, or other types. The display may present the monitored graphical data for viewing by a user.

It should be noted that the physical sign parameter monitored by the medical device may be one or may include a plurality of physical sign parameters. The specific amount is determined by the monitoring requirements in the actual application.

And theaudio acquisition device 102 is used for acquiring a voice signal which is input by a user and carries a freezing instruction, and sending the voice signal to the processor.

In practical application, when a user needs to freeze a certain piece of graphic data, a freezing instruction can be input to the medical device in a voice mode. The medical equipment is provided with an audio acquisition device, and the audio acquisition device can acquire the voice signal carrying the freezing instruction.

It should be noted that the time point when the user inputs the voice signal may not be fixed, and in order to implement real-time recording, the audio capture device may automatically remain in an operating state to continuously detect whether the voice signal is received. Of course, if the consideration is based on saving electric energy, saving computing resources of the medical device, and the like, the user may trigger to turn off the audio acquisition device, or the medical device may automatically turn off the audio acquisition device when the detection action of the audio acquisition device satisfies the preset turn-off condition. The preset closing condition may include, but is not limited to, that no voice signal is detected for a certain duration, and the like.

In case the audio capturing means is switched off, the audio capturing means may be restarted if the processor of the medical device receives a freeze start instruction. The manner in which the processor activates the audio capture device may include, but is not limited to, the following.

For example, a frozen physical key may be provided on the medical device, which the user may press, and upon a triggering operation, the key generates and sends a freeze initiation instruction to the processor. The processor then turns on the audio capture device to constantly prepare to capture the voice signal input by the user.

As another example, the medical device may present a frozen soft key via the display, the user may perform a click trigger operation on the soft key to trigger the display to freeze a start instruction, and the display sends the freeze start instruction to the processor. The processor then turns on the audio capture device to constantly prepare to capture the voice signal input by the user.

For another example, a photoelectric sensing device may be disposed on the medical device, and a user inputs a light shielding action meeting a preset requirement through the photoelectric sensing device, specifically, a time period for the user to shield the photoelectric sensing device reaches a preset time period, so that the photoelectric sensing device detects a light change condition meeting the requirement, and then generates a freezing start instruction and sends the freezing start instruction to the processor. The processor then turns on the audio capture device to constantly prepare to capture the voice signal input by the user.

For another example, an image capturing device may be disposed on the medical device, the user may display a gesture (e.g., drawing a triangle, a circle, etc.) meeting a preset requirement, and the image capturing device may capture an image including the gesture, and send the image to the processor. The processor may analyze the image content using image processing techniques, and may determine that a freeze initiation instruction has been received if a gesture motion meeting preset requirements is detected from the image. The processor then turns on the audio capture device to constantly prepare to capture the voice signal input by the user.

For another example, a power-on button is provided on the medical device, and the user may activate the button to start the medical device. If the medical equipment receives the equipment starting instruction, the audio acquisition device is started in the starting process so as to be ready for acquiring the voice signal input by the user.

For another example, when a patient needs to be monitored for a first time by using the medical device, the user may input a monitoring start instruction to the medical device, and may also input related information of the monitored object, such as name, age, gender, and the like, to the medical device. After the processor receives the monitoring starting instruction, the processor can determine that the freezing starting instruction is received, and then start the audio acquisition device to constantly prepare for acquiring the voice signal input by the user.

Of course, the above several ways of turning on the audio capture device are merely exemplary, and other ways that can be conceived by those skilled in the art are within the scope of the present invention.

And amemory 103 for storing software programs and data.

In particular, a software program for implementing the freezing of the graphics clip and its related data may be stored in the memory. The processor implements the function of freezing a graphics fragment described below by calling the software program and associated data in memory. The freezing of a graphics fragment may also be referred to as a snapshot or capture of the graphics fragment.

Aprocessor 104 for calling the data stored in the memory by running the software program stored in the memory, and performing at least the following steps: determining freeze information based on a freeze instruction in the speech signal, the freeze information comprising at least: a frozen target sign parameter and a frozen time period; acquiring a graph segment corresponding to a freezing time period from the graph data of the target sign parameters; the picture segment is frozen.

Specifically, after receiving the voice signal, the processor may parse the voice signal and extract the freeze command therefrom. And executing the step of freezing the picture based on the triggering of the freezing instruction. Firstly, the processor determines the relevant information of the image segment to be frozen according to the freezing instruction, wherein the relevant information at least comprises two items: the sign parameters (i.e. target sign parameters) corresponding to the image segment to be frozen and the freezing time period. How the two information items are determined is explained below, respectively.

First, how to determine the target physical sign parameter based on the freeze instruction in the voice signal.

One implementation is that the processor judges whether the freezing instruction contains a sign parameter identifier; if the freezing instruction comprises a sign parameter identifier, determining the sign parameter indicated by the sign parameter identifier as a target sign parameter; and if the sign parameter identification is not included in the freezing instruction, all the displayed sign parameters are used as target sign parameters.

Specifically, the number of the vital sign parameters monitored by the medical device may be multiple, and if the user finds that there is an abnormal fluctuation in a certain or some of the vital sign parameters, the user may input a freeze instruction using a voice signal, and indicate in the freeze instruction that the sign parameter identification needs to be frozen. For example, the freeze command entered by the user via the voice signal is "freeze blood oxygen," which indicates a waveform indicating freeze blood oxygen by the user. And after the processor receives the freezing instruction, the physical sign parameter indicated by the physical sign parameter identifier contained in the freezing instruction is used as the target physical sign parameter.

It should be noted that, the identifier of some physical sign parameters may be associated with a plurality of graphic data, and if the freezing instruction input by the user includes the identifier of the physical sign parameter of this type, the user may default to the default setting, in which case, the user indicates that all the associated graphic data are frozen. For example, the freeze command in the speech signal is "freeze ECG", which indicates that the user wishes to freeze the waveforms of all channels associated with the electrocardiogram. Of course, other default settings may also be made based on the user's usage habits. For example, the user is used to represent a certain or some specific channels of the electrocardiogram by using "ECG", so that the physical sign parameter identifier "ECG" can be previously associated with the specific channel or channels, and as long as the freezing instruction included in the user voice signal is detected to be "freezing ECG", it can be determined which channel or channels of the electrocardiogram the user indicates are frozen.

In addition, a sign parameter identifier can be included in the freezing instruction, for example, the freezing instruction in the voice signal is "freezing ECG II lead", which indicates that the user wants to freeze only ECG II lead and one waveform. The freeze instruction can also include multiple sign parameter identifiers at the same time, for example, the freeze instruction in the voice signal is "freeze ECG II lead, Art, CO 2", which indicates that the user wishes to freeze three waveforms at the same time: electrocardio II lead waveform, arterial pressure Art waveform and exhale last carbon dioxide waveform. It should be noted that if a plurality of sign parameter identifiers are included in the freeze instruction of the voice signal at the same time, it can be stated that the freeze time periods of the graph data of these sign parameter identifiers are the same.

It should be noted that, in the implementation provided above, the freeze instruction is included in one voice signal, but the freeze instruction may also be implemented by a plurality of voice signals. For example, a user inputs a first voice signal, a freezing instruction in the voice signal is used for starting a menu, and then the user is guided to input a second voice signal based on the menu, wherein the freezing instruction of the voice signal comprises a sign parameter identifier selected from the menu by the user.

Specifically, the user may input a voice signal containing a freeze instruction to the medical device, and the processor displays a menu containing one or more sign parameter identifiers after receiving the voice signal. The sign parameter identifiers in the menu may be identifiers of the respective sign parameters currently displayed by the display. And the user selects a sign parameter identifier according to the freezing requirement, and the selected sign parameter identifier is contained in the voice signal and is input to the medical equipment. The sign parameter identifier may be a label of the sign parameter in the menu, or may be a name of the sign parameter. After the processor receives the voice signal, the physical sign parameter indicated by the voice signal is determined as the target physical sign parameter.

However, if the processor does not resolve the sign parameter identification from the freeze instruction, the processor may take all of the sign parameters displayed by the display as the target sign parameters. For example, if the voice signal input by the user is "frozen", the processor determines all the physical parameters displayed by the display, such as all channels of electrocardio, blood oxygen, invasive arterial pressure, central venous pressure, and end-expiratory carbon dioxide, as the target physical parameters.

It should be noted that, the display area of the display is limited, and in practical applications, there may be two special cases: firstly, the display interface displays other data of the physical sign parameters, but does not display the graphic data of the physical sign parameters, for example, the display interface only displays the monitoring values of the physical sign parameters, but does not display the oscillogram of the physical sign parameters due to insufficient display space. Secondly, when the medical device monitors a plurality of physical sign parameters, the display interface may currently display only the graphic data of a part of the physical sign parameters, the graphic data of other physical sign parameters are in a state to be displayed, and the user may switch to display the graphic data of other physical sign parameters by switching operations, such as inputting a sliding gesture on the display.

If the situation that the whole graphic data is not displayed due to the limitation of the display area size exists, the processor may only use the physical sign parameter currently displayed by the display as the target physical sign parameter, or both the currently displayed physical sign parameter and the physical sign parameter to be displayed as the target physical sign parameter.

Second, how to determine the freeze period based on a freeze instruction in the speech signal.

And after receiving the voice signal, the processor analyzes the voice signal to obtain a freezing instruction, and judges whether the freezing instruction contains a time parameter related to a freezing time period. If so, the processor determines a freeze time period according to the time parameter; if not, the processor obtains a preset freezing time length and determines a time period of the preset freezing time length before or after the time point of receiving the freezing instruction as the freezing time period. The processor analyzes the freezing instruction from the received voice signal, namely, the processor receives the freezing instruction.

Specifically, the user may preset the medical device according to actual needs, set a default freezing time, and set whether to freeze the graphic data before the receiving time point or to freeze the graphic data after the receiving time point after receiving the freezing instruction. Therefore, when the processor determines that the freeze instruction does not include the time parameter, the processor determines the time point at which the freeze instruction is received as a time end point according to the preset content, and determines the freeze time period by freezing from the time end point or by determining the freeze time period ahead by using the time end point as an end time point. The length of the freezing period is the above-described preset freezing period, regardless of whether the freezing period is determined forward or backward.

For example, the processor receives a voice signal at 10 o ' clock 35 min 00 sec, extracts a freezing instruction "frozen blood oxygen" from the voice signal, and if the processor determines that the freezing instruction does not include a time parameter, obtains setting data, and if the setting data indicates that a time period after the freezing instruction is taken as a freezing time period and the freezing time period is 2 minutes, the processor determines that the freezing time period is a time period starting from 10 o ' clock 35 min 00 sec to 10 o ' clock 37 min 00 sec.

The voice signal may include a time parameter indicating a freezing time period, and the processor determines the freezing time period according to the time parameter if the freezing instruction is judged to include the time parameter.

For example, if the freeze duration is included in the freeze instruction, the processor determines a period of the freeze duration before or after a time point at which the freeze instruction is received as the freeze period.

Specifically, the user may explicitly indicate the time length of the freeze in the voice signal, for example, the voice signal of the user is "freeze for 3 minutes", so that the processor interprets the freeze instruction from the voice signal, and then takes the time length in the freeze instruction as the duration of the freeze time period. The time point at which the freeze instruction is received may be a start time end point of the freeze period or an end time end point of the freeze period. The specific setting may be set by default, and the setting manner specifically refers to the above description about the setting without including the time parameter, which is not described herein again.

Of course, the user may also explicitly indicate the relation between the freezing time period and the current time point in the voice signal, for example, if the voice signal is "3 minutes after freezing", indicating that it is necessary to freeze the graphic data 3 minutes after the current time point, or if the voice signal is "3 minutes before freezing", indicating that it is necessary to freeze the graphic data 3 minutes before the current time point. In this case, after the processor analyzes the freeze instruction from the voice signal, the processor may use a time point at which the freeze instruction is analyzed as an end point and a time period before or after the time point as a freeze time period according to the instruction of the freeze instruction.

For another example, if the start instruction and the end instruction are included in the freeze instruction, the processor determines a time period from a time point at which the start instruction is received to a time point at which the end instruction is received as the freeze time period.

Specifically, if the user may find that the graphic data is abnormal at a certain time point, a voice signal is input to the medical device at the time point as "free freeze start", and when the graphic data is found to be normal or the user determines that the freezing needs to be ended, a voice signal is input to the medical device as "free freeze end". After the processor receives the voice signal, if the starting instruction is analyzed from the voice signal, the graph data is frozen; if the ending instruction is parsed from the voice signal, the freezing of the graphic data is ended. In this implementation, the user specifies that a segment of the graph is frozen for any length of time, and the freezing period starts from the time point when the start instruction is received and ends at the time point when the end instruction is received. It should be noted that, in this case, although one voice command does not explicitly indicate the time parameter, the combination of the two voice commands implicitly indicates the time parameter, that is, the freezing time period is defined by the starting voice command and the ending voice command. The above describes a case, that is, a single voice signal does not carry a time parameter, a preset time length is obtained as a freezing time period, two different freezing instruction formats can be preset for distinguishing from the case, and a user only needs to input a corresponding freezing instruction according to the different formats.

For another example, if the start time point and the end time point are included in the freeze instruction, the period from the start time point to the end time point is determined as the freeze period.

Specifically, if a user finds that a certain graphic segment in the graphic data is abnormal, the user may explicitly indicate a time point of freezing start and a time point of freezing end in the voice signal, for example, "5 points 30 minutes 21 seconds, 5 points 35 minutes 21 seconds". The processor analyzes the freezing instruction from the voice signal, then takes a smaller time point in the freezing instruction as a starting time point, takes a larger time point in the freezing instruction as an ending time point, and determines a time period between the two time points as a freezing time period.

It should be noted that some time elements may be omitted from the speech in order to facilitate the user to input speech. For example, if it is desired to freeze the graphical data within the current hour, the user-entered time parameter may not include an indication of the hour, such as a speech signal "30 minutes 21 seconds, 35 minutes 21 seconds", and the processor, after resolving this type of time parameter, defaults to supplementing the hour at the current time point as an hour element. To further facilitate user input of speech, the user may not input the name of a time element, and the processor resolves to a previous time element of the value of the default time element and automatically supplements the next time element of the previous time element with the value. For example, the voice signal inputted by the user is "30 minutes 21 and 35 minutes 21", and the processor analyzes the voice signal, finds the default time element of the numerical value "21", and automatically supplements the next level time element "second" of "minutes". Default inputs for other time elements are handled similarly and are not described in detail herein.

Although the determination of the target physical sign parameter and the freeze time period are described above, the determination does not mean that the two information items are input into the medical apparatus by different voice signals. The user can indicate both the parameter identification for determining the target physical sign parameter and the time parameter of the freezing time period in one voice signal, for example, the voice signal is "freeze blood oxygen for 3 minutes", "start to freeze ECG, end to freeze ECG", "freeze blood oxygen for 5 points 30 minutes 21 seconds, 5 points 35 minutes 21 seconds". After receiving the voice signal, the processor analyzes the voice signal to obtain a freezing instruction, and then determines both the target physical sign parameter and the freezing time period based on the same freezing instruction.

After the target sign parameters and the freezing time periods are determined, the image data corresponding to the target sign parameters can be frozen according to the indication of the freezing time periods, and frozen image segments are obtained.

According to the technical scheme, the medical equipment provided by the invention comprises a display, an audio acquisition device, a memory and a processor. The display is used for showing the graphic data of sign parameter, and audio acquisition device is used for gathering the voice signal that carries freezing instruction of user's input to send voice signal to the treater, the software program that the treater can be stored in the operation memory realizes freezing the function according to following mode: and determining target physical sign parameters and a freezing time period according to a freezing instruction in the voice signal, and freezing a graph segment in the graph data according to the two items of freezing information. Therefore, by using the medical equipment provided by the invention, a user can instruct the medical equipment to freeze the graphic data through the voice signal, so that the steps of manually operating the equipment by the user can be simplified, the user experience is improved, and the medical equipment can be widely applied to aseptic operation scenes for avoiding cross infection.

The frozen graphic segments may be stored and displayed for viewing by a user. In particular, the display of the medical device is also used for displaying the frozen graphical segment. The display may automatically display the graphic segment after freezing the graphic segment, or may also display the frozen graphic segment based on a viewing instruction input by a user.

The medical device may also be instructed to perform a modification function by a voice signal if the user wants to modify the frozen graphic segment. Specifically, the audio acquisition device is further configured to receive a modification instruction for the target graphic segment, where the modification instruction is used to indicate a modified freeze time period; sending a modification instruction to the processor; and the processor is further used for replacing the target graphic segment with a graphic segment corresponding to the freezing time period indicated by the modification instruction.

Wherein, if the user wants to modify the freezing time period of a certain graphic segment, the identification of the graphic segment is included in the voice signal. In addition, the voice signal needs to include an indication related to modification to indicate that the voice signal includes a modification instruction. For example, if the voice signal is "modified blood oxygen is 5 minutes", the processor may analyze that the piece of voice signal carries a modification instruction, where the modification instruction indicates that there is a modified freezing time period, and specifically indicates a time length of the modified freezing time period.

And the processor receives the voice signal, analyzes the voice signal to obtain a modification instruction, modifies the target graphic segment indicated by the modification instruction, and modifies the target graphic segment into a graphic segment corresponding to the freezing time period indicated by the modification instruction. For example, the frozen blood oxygen graphic fragment is modified from 3 minutes to 5 minutes.

The medical device described above realizes the function of freezing the graphic segment mainly based on the instruction of the voice signal. Of course, the invention also provides a medical device which enables a user to indicate the implementation of the freeze function by a gesture action.

Referring to fig. 2, the medical device may specifically include: adisplay 201, animage acquisition device 202, amemory 203, and aprocessor 204. Theprocessor 204 is connected to thedisplay 201, theimage capturing device 202, and thememory 203. It should be noted that the structure of the medical apparatus and the implementation of each device module are similar to those of the medical apparatus shown in fig. 1, and are not repeated below, and only the differences will be briefly described.

Adisplay 201 for displaying the graphical data of at least one physical sign parameter of the monitored subject.

And theimage acquisition device 202 is used for acquiring image data which is input by a user and carries a freezing instruction, and sending the image data to the processor.

The user can display the gesture actions related to freezing to the image acquisition device of the medical equipment, the image acquisition device can acquire image data containing the gesture actions related to freezing, and the image data are sent to the processor. The image acquisition device may specifically be a camera.

And amemory 203 for storing software programs and data.

Aprocessor 204 for executing the software program stored in the memory and calling the data stored in the memory to perform at least the following steps: determining freeze information based on a freeze instruction in the image data, the freeze information including at least: a frozen target sign parameter and a frozen time period; acquiring a graph segment corresponding to a freezing time period from the graph data of the target sign parameters; the picture segment is frozen.

In one implementation, the processor executes the step of determining the target physical sign parameter based on the freezing instruction in the image data, and the specific process is as follows: judging whether the freezing instruction contains sign parameter identification or not; if the freezing instruction comprises a sign parameter identifier, determining the sign parameter indicated by the sign parameter identifier as a target sign parameter; and if the sign parameter identification is not included in the freezing instruction, all the displayed sign parameters are used as target sign parameters.

Wherein, after the processor receives the image data, the image data can be analyzed by using an image processing technology. And if the analysis result contains gesture actions related to freezing, indicating that the image data carries a freezing instruction. The freeze instruction may indicate a sign parameter that is desired to be frozen, and specific implementations may include the following.

One implementation manner is that the corresponding relationship between the gesture motion and the sign parameter identifier can be preset, and when a user wants to freeze a certain sign parameter, the user inputs the gesture motion corresponding to the sign parameter identifier. For example, the preset gesture "2" indicates freezing the graphical data of the second vital sign parameter displayed by the display.

Another implementation manner is that the corresponding relationship between the gesture action and the opening menu can be preset, and after the corresponding gesture action is analyzed from the image data, a menu containing one or more sign parameter options is provided. The user indicates a sign parameter identification or sign parameters through gesture actions. For example, the user presents a gesture of drawing a circle to the image acquisition device, and after the processor analyzes the gesture of drawing the circle from the image data acquired by the image acquisition device, the sign parameters displayed by the display can be included in the menu and provided to the user. The sign parameters in the menu can have numbers, and the user can indicate the selected sign parameters through gesture actions corresponding to the numbers. For example, the user traces the number "2" or presents a gesture representing "2" (e.g., presents two fingers) to prompt selection of the sign parameter numbered 2.

In one implementation, the processor executes the step of determining the freezing time period based on a freezing instruction in the image data, and the specific process is as follows: if the freezing instruction comprises the freezing time length, determining a time period of the freezing time length before or after the time point of receiving the freezing instruction as the freezing time period; if the freezing instruction comprises a starting instruction and an ending instruction, determining a time period from the time point of receiving the starting instruction to the time point of receiving the ending instruction as a freezing time period; if the freezing instruction does not include the freezing time length, obtaining a preset freezing time length, and determining a time period of the preset freezing time length before or after the time point of receiving the freezing instruction as the freezing time period.

The freeze instruction includes a freeze duration, and the freeze duration is implemented by a user indicating the freeze duration through a gesture action, for example, a number of a stroke of the freeze duration, or a gesture showing the number of the freeze duration. Specifically, for example, the user traces a digit "3" or displays a gesture indicating "3" (e.g., three fingers) to indicate that the freeze duration is 3 minutes.

The implementation manner of including the start instruction and the end instruction in the freeze instruction is that gesture actions corresponding to the start instruction and the end instruction are respectively set in advance, and the user inputs the corresponding gesture actions according to the corresponding relationship. For example, a start instruction is to draw a circle, an end instruction is to draw a triangle, and so on.

In addition, the processor can be used for starting the image acquisition device if a freezing starting instruction is received.

In addition, the medical device may further include: photoelectric sensing devices or freezing keys; the manner in which the processor receives the freeze initiation instruction includes any one of the following: if the photoelectric sensing device detects that the light change condition meets the preset requirement, a freezing starting instruction is generated and sent to the processor; if the freezing key receives the triggering operation, a freezing starting instruction is generated and sent to the processor; if an equipment starting instruction is received, determining that a freezing starting instruction is received; and if a monitoring starting instruction for the monitored object is received, determining that a freezing starting instruction is received.

Additionally, the processor may be further configured to display the frozen graphics fragments.

In addition, the image acquisition device can be further used for receiving a modification instruction of the target graphic segment, wherein the modification instruction is used for indicating the modified freezing time period; sending a modification instruction to the processor; and the processor is further used for replacing the target graphic segment with a graphic segment corresponding to the freezing time period indicated by the modification instruction.

The medical equipment can meet the requirement that a user can realize the freezing function through gesture actions. In addition, the invention also can provide a medical device, and a user can control the medical device to realize the freezing function through voice and gesture actions. The medical device specifically includes: the device comprises a display, an audio acquisition device, an image acquisition device, a memory and a processor. The processor is respectively connected with the display, the audio acquisition device, the image acquisition device and the memory.

Specifically, the audio acquisition device may acquire a voice signal of the user, and the image acquisition device may acquire image data including a gesture motion input by the user, so that the user may input a part of the freeze instruction through the voice signal and input a part of the freeze instruction through the gesture motion. Together, the two types of freeze instructions instruct the medical device to perform the freeze function. A processor for determining freeze information based on a freeze instruction in the speech signal and a freeze instruction in the image data, the freeze information comprising at least: a frozen target sign parameter and a frozen time period; acquiring a graph segment corresponding to a freezing time period from the graph data of the target sign parameters; the picture segment is frozen.

In one implementation, a user may input a freeze instruction using a voice signal to open a menu containing the sign parameters and indicate a selected sign parameter identification using a gesture action. In another implementation, the user may input the target sign parameter identification using a voice signal and indicate the freeze time period using a gesture. For example, the user enters a speech signal "freeze ECG" and indicates a "3" with a gesture motion to indicate a waveform segment that freezes each channel of the electrocardiogram for 3 minutes. Or may also include other examples of speech signals in combination with gesture actions as will occur to those of skill in the art.

During the monitoring process of the vital signs of the patient, the frozen image segments can provide data support for monitoring abnormality analysis, for example, medical personnel can determine the reason of abnormality of physiological sign parameters of the patient by analyzing the frozen image segments. In practice, analysis of the frozen image segments by the healthcare worker typically includes measurement and overlay contrast viewing of the frozen image segments.

Fig. 3 shows the structure of a medical device provided by the present invention. As shown in fig. 3, the medical device may specifically include: adisplay 301, aninput device 302, amemory 303, and aprocessor 304, wherein theprocessor 304 is connected to thedisplay 301, theinput device 302, and thememory 303, respectively.

Adisplay 301 for displaying a graphical segment of the vital sign parameters; and displaying the measurement tool.

The image segment displayed by the display is a frozen image segment, and after the image segment is displayed to a user, the user can use the measuring tool to measure the geometric characteristics of the image segment. The graphic segments may be any kind of graphic segments that can be understood and desired by a person skilled in the art, and may specifically include, for example: an electrocardiographic waveform segment, a respiratory waveform segment, or a blood pressure waveform segment.

Theinput device 302 is used for receiving a measurement starting instruction input by a user and sending the measurement starting instruction to the processor.

Wherein, the user can input the measurement starting instruction to the medical device through the input device, and the measurement starting instruction received by the input device is sent to the processor, so that the processor starts the measurement function of the graphic segment.

In particular, the input device may comprise an audio capture device or an image capture device. The audio acquisition device is used for acquiring a voice signal which is input by a user and carries a measurement starting instruction; and the image acquisition device is used for acquiring gesture actions which are input by a user and carry measurement starting instructions. Therefore, under the condition that the medical equipment comprises the audio acquisition device, a user can control the medical equipment to start measurement through voice; in case the medical device comprises image acquisition means, the user may control the medical device by a gesture motion to initiate a measurement.

The user inputs a voice signal carrying a measurement start instruction, which may include the following examples: for example, a user inputs a speech signal "measure"; in addition, the implementation of the measurement function needs to be dependent on the measurement tool, so the user can input a voice signal including the name of the measurement tool, such as "caliper", "angle gauge", or the like. The caliper gauge is a length measuring tool corresponding to the caliper gauge, and the length measuring tool is used for measuring the distance or the length between two points; "Angle gauge" corresponds to an angle measuring tool for measuring the angle between two lines and/or the slope of a line.

The user inputs a gesture action carrying a measurement starting instruction, and the method specifically comprises the following steps: the gesture action corresponding to the measurement starting instruction can be predefined, and the user only needs to input the corresponding gesture action. For example, the gesture motion corresponding to the measurement starting instruction may be to draw a triangle, and the like.

Or, the input device may further include a touch display, the user may perform a touch operation on the graphic segment of the physical sign parameter, and the touch display generates a measurement start instruction to send to the processor in response to the touch operation. For example, the user may long press, single click, or double click on a graphic segment to trigger the touch-sensitive display to generate a measurement initiation instruction.

Thememory 303 is used for storing software programs and data.

Aprocessor 304 for executing the software program stored in the memory, calling the data stored in the memory, and performing at least the following steps: and generating a measuring tool indicated by the measurement starting instruction in response to the measurement starting instruction, wherein the measuring tool is used for measuring the geometric characteristics of the lines in the graphic segments.

After the measurement starting instruction is sent to the processor, the processor generates a corresponding measurement tool. The specific measurement tool generated by the processor may be determined by the measurement initiation instruction. For example, the name of the measurement tool, such as "caliper" or "angle gauge", may be included in the measurement start command, so that the processor generates the corresponding measurement tool. If the measurement start instruction does not include the name of the measurement tool, the processor generates the set measurement tool according to the default setting. For example, default settings are to generate a length measurement tool, generate an angle measurement tool, or generate a menu containing one or more measurement tool selection items. If the processor generates a menu of choices, the processor generates the corresponding measurement tool based on the user's selection.

The data related to the measurement tool generated by the processor is sent to the display. The display displays the graphic segment and simultaneously displays the measuring tool according to the related data, so that a user can control the measuring tool to measure the geometric characteristics of the lines in the graphic segment.

In particular, the geometric features include any one or more of the following: the horizontal distance between two points in the line, the vertical distance between two points in the line, the slope of two points in the line, and the angle between the horizontal line and the connecting line of two points in the line. Wherein a single length measuring tool may be used to measure both horizontal and vertical distances; angle measurement tools can be used to measure slope as well as angle; in addition, the combined measuring tools of a plurality of length measuring tools can also be used for measuring the slope and the angle.

The user may control the measuring tool to measure a particular line in the graphical segment. To implement this control function, the display of the medical device may be embodied as a touch-sensitive display to receive control gestures of the user.

It should be noted that the illustrated measuring tool may include at least one measurement controllable end. As shown in fig. 4, the length measuring tool includes a measuring line and two measuring controllable ends, the measuring controllable ends are two end points of the measuring line, and the user can drag the measuring controllable ends to change the length and position of the length measuring tool; the angle measuring tool comprises two measuring lines and three measuring controllable ends, the measuring controllable ends comprise intersections of the two measuring lines and other two end points of the two measuring lines, and similarly, a user can drag the measuring controllable ends to change the length and the position of the measuring lines of the angle measuring tool.

Based on the movement operation of the user on the measurement controllable end on the touch display, the touch display is further used for receiving a movement instruction of the user on the measurement controllable end and sending the movement instruction to the processor. The processor is further used for determining a target position indicated by the movement instruction according to the movement instruction and sending the target position to the touch display. The touch display is also used for displaying the measurement controllable terminal at the target position. Therefore, based on the technical scheme, the medical equipment can achieve the purpose of controlling the measuring tool in a touch mode by a user. When a user wants to measure the geometric feature of which line in the graphic segment by using the measuring tool, the corresponding measuring tool is controlled on the touch display, and the measuring tool is moved to a corresponding position.

Further, the processor is further configured to measure the geometric features of the lines in the graphic segment using a measurement tool that measures the controllable end at the target location; and sending the geometric features to a display; the display is also used to display geometric features.

The following illustrates the measurement of the length measuring tool and the measurement process of the angle measuring tool, respectively.

As shown in FIG. 5A, the user can control the position of the two endpoints of the length measuring tool on the frozen waveform by a two-finger control gesture (e.g., thumb and forefinger controlling the two endpoints of a length measuring tool, respectively). The length measuring tool may be lengthened or shortened as the distance between the thumb and the index finger increases or decreases. The adjusted length measurement tool may be horizontal for measuring the horizontal distance between two points on the frozen waveform; the adjusted length measuring tool may also be vertical for measuring the perpendicular distance between two points on the frozen waveform. During measurement, the touch display may display a current measurement value between two points in real time, for example, a horizontal distance value measured by the length measuring tool 1 in real time is 420ms, and a vertical distance value measured by the length measuring tool 2 in real time is 1.1 mV. In addition, the length measuring tool can also be inclined at a certain angle, for example, the other finger can be rotated by taking the thumb or the index finger as a fixed point, and the inclination angle of the length measuring tool can be adjusted.

As shown in FIG. 5B, the angle measuring tool comprises A, B and O measuring controllable ends, the user can move the point A, the point O and the point B to the positions to be measured respectively by fingers, and the processor automatically calculates the value of the slope of the side AO relative to the side BO and the value of the angle a between the side AO and the side BO.

It should be noted that two length measurement tools can also be combined into one angle measurement tool, and the combined length measurement tool, like the angle measurement tool, can be used for measuring the slope of the lines and the angle between the lines. Specifically, the user may invoke a new length measurement tool via the input device after completing the measurement using a length measurement tool. For example, the "create new caliper" signal controls the medical device to display a new length measuring tool.

The input device is also used for receiving the merging instruction input by the user and sending the merging instruction to the processor, wherein the merging instruction can be realized by voice, non-contact gesture actions or contact actions such as double-click and the like; the processor is further configured to, in response to the merge instruction, coincide an end of one measurement line with an end of another measurement line to generate an angle measurement tool; the angle measuring tool is used for measuring the angle and the slope of a connecting line formed by two points in the graph segment.

For example, the display displays a first length measuring tool and a second length measuring tool, where two ends of the first length measuring tool are respectively referred to as point a and point B, and two ends of the second length measuring tool are respectively referred to as point C and point D. The user enters a merge command, and the processor, in response to the merge command, causes point a of the first length measurement tool to coincide with point C of the second length measurement tool, thereby obtaining an angle measurement tool. The combined angle measurement tool may take slope and angle measurements based on the indications of the measurement instructions. The measurement instruction may be generated based on input such as a user double-click coincident point operation on the touch-sensitive display screen, a user input of a "calculate slope and angle" voice signal.

After the measurement is finished, the user can store the measurement result by confirming the instruction. The confirmation instruction may be a voice instruction, a non-contact gesture action, or a contact action on a touch-sensitive display such as a double click, a single click, or the like.

In addition, after the user uses one measuring tool to complete the measurement of a certain line of the graphic segment, the user can call a new measuring tool through the input device, so that the medical device can create a plurality of measuring tools on one graphic segment and complete the measurement of a plurality of geometric features of the same graphic segment by using a plurality of measuring tools. Of course, if there are a plurality of displayed graphic segments, a plurality of different measuring tools may be used to measure the different graphic segments respectively.

In the measurement of the graphic segment, it may be necessary to control the display state of the graphic segment, the condition of the measurement tool, and the like. Therefore, the user can also input a measurement auxiliary instruction through the input device during the measurement process so as to realize auxiliary control of the measurement process.

Specifically, the input device is further configured to receive a measurement assistance instruction input by a user, and send the measurement assistance instruction to the processor; likewise, the measurement assistance command may be a voice command, a non-contact gesture motion, or a contact motion on a touch-sensitive display. The processor is also used for responding to the measurement auxiliary instruction and executing a measurement auxiliary action corresponding to the measurement auxiliary instruction; wherein the measurement assistance action comprises any one or more of: enlarging the graphic segment, reducing the graphic segment, rotating the graphic segment, deleting the measuring tool, adding the measuring tool and combining the measuring tools.

In practical applications, the medical staff may need to compare a plurality of graphic segments, and therefore, the plurality of graphic segments need to be displayed in a superposition manner.

One situation is that the user wants to compare multiple graphical segments of the same vital sign parameter at multiple different freeze periods: for example, it is desirable to compare a segment of the waveform of the oximetry waveform at 10 o 'clock 50 and a segment of the waveform at 11 o' clock 50, as well as, for example, to compare segments of the QRS waveform of the ECG II lead waveform at a plurality of different time periods. For ease of understanding, this comparison may be referred to as a lateral comparison.

Alternatively, the user may want to compare the graph segments of multiple different vital sign parameters over the same freeze time period, for example, the Art waveform segment and the CVP waveform segment over the same time period. For ease of understanding, this comparison may be referred to as a longitudinal comparison.

The user inputs overlay instructions to the medical device, which may indicate the graphic segments that need to be overlaid, which may be referred to as target graphic segments for ease of description. The input equipment is also used for receiving a superposition instruction input by a user and sending the superposition instruction to the processor; the processor is also used for responding to the superposition instruction, overlapping the upper layer and the lower layer of the target graphic segment indicated by the superposition instruction in the same display area, and sending an overlapping result to the display; the display is also used to display the overlay results.

As shown in fig. 6A, two waveform segments of different time periods are extracted from the waveform of the same physical sign parameter, and according to a superimposition instruction input by a user, the waveform segment 1 and the waveform segment 2 are superimposed on the upper and lower image layers in the same display area. As shown in fig. 6B, the Art waveform segment acquired at the same time period is superimposed with the CVP waveform segment.

It should be noted that the overlay command can be implemented by voice, non-contact gesture motion, and contact motion. In one implementation, the overlay instruction may be implemented by one instruction. For example, the medical device may display graphical segments of a plurality of vital sign parameters of the same time period, the user may input a voice signal "overlay Art CVP", and the medical device displays the graphical segments of the two vital sign parameters of Art and CVP in an overlay manner. In another implementation, the overlay instruction may be implemented by multiple instructions. For example, the user inputs a voice signal "superposition" and then selects a plurality of graphic segments to be superposed in the touch-sensitive display, and the medical device displays the plurality of graphic segments selected by the user in a superposition manner in response to the two superposition instructions.

Further, the user may also trigger the measurement function, and perform measurement of geometric features on the superimposed graphic segments using a measurement tool, which is not described herein again.

In addition, the user may add annotation content, such as time, operator, etc., to the measurements of the graphical segment. Specifically, the input device is also used for receiving annotation content about the geometric features input by a user and sending the annotation content to the processor; the processor is also configured to save the geometric features in association with the annotation content.

The above superimposed graphic segments are all graphic segments for a single sign parameter, and in practical application, a user also desires to perform comparative analysis on a plurality of sign parameters at a plurality of different time periods simultaneously. Therefore, a plurality of physical sign parameters can be combined into a graph in a composite form, and then the plurality of composite graphs can be superposed.

To achieve this function, the present invention provides a medical apparatus which may include: input device, processor and display.

The input device is used for receiving a superposition instruction input by a user, and the superposition instruction comprises a plurality of target sign parameters and a plurality of target time points; sending the superposition instruction to a processor; the processor is used for responding to the superposition instruction and obtaining the parameter value of each target physical sign parameter at each target time point; generating a geometric figure according to all parameter values corresponding to the target time points aiming at each target time point, wherein the geometric figure is a spider-web graph; overlapping the centers of the geometric figures of different target time points to obtain an overlapped figure; sending the overlay graphic to a display; a display for displaying the overlay graphic.

It should be noted that the distance between the corner and the center point in the geometric figure is determined by the parameter value, so that the geometric figures generated by different parameter values of the same target physical sign parameter are different. By superimposing different geometric figures, differences between different parameter values of the same target sign parameter can be analyzed.

Specifically, the user can realize the superposition of the composite graph through voice signals or gesture actions. Thus, the input device may specifically include: an audio acquisition device or an image acquisition device. The audio acquisition device is used for acquiring a superposition instruction input by a user through a voice signal; and the image acquisition device is used for acquiring the superposition instruction input by the user through the gesture action.

For example, the speech signal input by the user is "superposition parameters CI, ScvO2, pArt-M, SVRI, SVV, today 11: 00 and 12:00 compare ". And after receiving the voice signal, the processor analyzes the voice signal to obtain a superposition instruction. And according to the indication of the superposition instruction, obtaining the parameter values of the six parameters at 11 points on the current day and the parameter values at 12 points on the current day, generating a pentagonal graph by using the six parameter values at 11 points, and generating a pentagonal graph by using the six parameter values at 12 points. And then, the central points of the two pentagons are overlapped to obtain a superposed graph and display the superposed graph, wherein the display effect is shown in fig. 6C. It should be noted that, in order to facilitate the user to perform voice control, the target sign parameters for generating the geometric figure may be preset, and the voice signal of the user only needs to include a time period that needs to be compared.

The processed data are all graphic data, such as trend graphs and waveform graphs. The invention can also process the image data of the monitored object. The existing image data processing mode requires medical staff to input control instructions by contacting medical equipment, such as pressing entity keys. In order to simplify the operation mode of medical staff, the invention provides medical equipment which can provide a voice control function for the medical staff and control the image data processing process through voice by the medical staff.

Fig. 7 shows the structure of a medical device provided by the present invention. Specifically, the medical device may include: adisplay 701, anaudio acquisition device 702, amemory 703, and aprocessor 704. Theprocessor 704 is connected to thedisplay 701, theaudio capture device 702, and thememory 703, respectively.

Adisplay 701 for displaying a monitoring image of a physiological system of a monitoring subject; the monitoring image may specifically include a heart three-dimensional image, a respiratory system image, or a blood circulation system image.

Theaudio acquisition device 702 is configured to receive a voice signal carrying an image processing instruction input by a user, and send the voice signal to the processor; the image processing instruction may specifically include an image adjustment instruction, where the image adjustment instruction includes: image reduction, image enlargement, image rotation, image change rate increase, or image change rate decrease. Image variation rates such as heart beat rate, lung breathing rate, etc.

Thememory 703 is used for storing software programs and data.

Aprocessor 704 for executing at least the following steps by executing the software program stored in the memory and calling the data stored in the memory: processing the monitoring image according to a processing mode indicated by an image processing instruction in the voice signal; and transmitting the processed monitoring image to a display so that thedisplay 701 displays the processed monitoring image.

In a specific implementation, the image processing instruction may be specifically an image freeze instruction for indicating a freeze region, such as a voice instruction to freeze a heart region in the circulatory system. It should be noted that the monitoring image displayed by the display may be real-time monitoring data, and the displayed image data is different when the physiological sign states of the monitored subjects are different. That is, the monitor image displayed by the display is changed in real time. And after receiving the image freezing instruction, the processor intercepts the monitoring image of the freezing area at the time point of receiving the voice signal to obtain the intercepted monitoring image. The intercepted monitored image is frozen image data.

Note that the function of freezing image data may be implemented by a touch gesture. Specifically, the display is a touch display, a user can select an area in image data displayed on the touch display through a sliding track, and the processor freezes the image data corresponding to the area.

The frozen image data may be used for further analysis and may be further adjusted, such as reduced, enlarged or rotated, to facilitate the analysis process.

Therefore, the audio acquisition device is also used for receiving the voice signal which carries the image adjustment instruction and is input by the user, and sending the voice signal to the processor, wherein the image adjustment instruction comprises: an image reduction instruction, an image enlargement instruction, or an image rotation instruction; the processor is also used for adjusting the intercepted monitoring image according to the instruction of the image adjusting instruction in the voice signal and sending the monitoring image obtained by adjustment to the display; and the display is also used for displaying the adjusted monitoring image.

Similarly, the above adjustment of the freeze-monitored image may also be implemented by a contact gesture, such as a two-finger distance-reducing gesture representing an image-reducing instruction, a two-finger distance-widening gesture representing an image-enlarging instruction, a one-finger circle-drawing gesture representing an image-rotating instruction, and so on.

In practical application, the freezing area may be associated with vital sign parameter measurement data, and the associated vital sign parameter measurement data may be displayed together with the intercepted monitoring image. Specifically, the processor is further configured to obtain sign parameter measurement data of the monitored subject related to the freezing region, and send the sign parameter measurement data to the display; the display is also used for displaying the physical sign parameter measurement data.

For example, as shown in fig. 8A, in the circulatory system monitoring image, an image of a heart portion is cut (a portion selected by a circle represents the cut image), and the partial image has an association relationship with a feature parameter, i.e., the peripheral vascular resistance index SVRI, so that the display result includes not only the cut monitoring image but also a trend graph of the peripheral vascular resistance index over a past period of time, e.g., 15 minutes, as shown in fig. 8A.

Further, if the physical sign parameter measurement data includes: a trend graph of the sign parameters corresponding to the freezing area in a preset time period; the user may also zoom in and out on the trend graph through speech.

Specifically, the audio acquisition device is further configured to receive a voice signal carrying a trend graph scaling instruction input by a user, and send the voice signal to the processor; the processor is further used for zooming the trend graph in the measurement duration dimension and/or the measurement value display range dimension according to the indication of the trend graph zooming instruction in the voice signal, and sending the zoomed trend graph to the display; and the display is also used for displaying the trend graph obtained by zooming.

The trend graph comprises two dimensions, measuring time and a measuring value display range. As shown in the peripheral vascular resistance index trend graph shown in fig. 8B, according to the measurement duration dimension in the trend graph, the measurement duration of the trend graph is 15 minutes, the measurement value display range is 1000 to 3500, and the measurement value display range can also be referred to as a measurement value amplitude scale.

The scaling adjustment includes two types, one is to scale in the dimension of the measurement duration, such as extending or reducing the measurement duration; and secondly, scaling the dimension of the display range of the measured value, and if the display range of the measured value is enlarged or reduced. Likewise, the above adjustment of the trend graph may be implemented by contact or non-contact gestures.

In order to realize the control of the monitored images through non-contact gestures, the invention provides the following medical equipment. Specifically, the method comprises the following steps:

a medical device, comprising: display, image acquisition device and processor.
