Description

TECHNICAL FIELD
• This invention relates to the field of health care devices for gathering, displaying and transmitting health care data concerning the vital signs of a patient, particularly to portable nursing devices for gathering such data, and still more particularly to portable devices that provide for assimilating a plurality of different types of health care data, including patient identity, using a single integrated device.
BACKGROUND OF THE INVENTION
• In a medical facility such as a hospital, clinic or doctor's office, the creation and maintenance of patient files is critical to recording vital data and history of a patients treatment. Patient files include patient identifying information as well as a variety of health care data associated with the patient. Identifying information is routinely taken at intake of a patient and typically includes, for example, name, age, sex and insurance information, which is used to establish the base file for the patient. In addition, routine health care data such as temperature, pulse, blood pressure and the like are typically hand recorded at or near intake and included in a hard-copy paper file. The file is typically physically transferred to a patient examination room where further health care data and notes may be entered by a health care provider and manually recorded into the file.
• If the patient is to be admitted to a hospital, an identification bracelet is typically created to be worn on the patient's wrist for follow-up care, and the patient's file is transferred to the patient's bedside. At the bedside, the file is manually updated upon periodic visits by a physician or nurse who manually records notes and other health care data into the file. Prescription and diagnosis information is also recorded in the file. In instances before or after a significant medical procedure such as birth or surgery, basic vital signs such as temperature, pulse, blood pressure, respiratory rate, oximetry, electrocardiogram (ECG) or other data pertaining the patient's body may be continuously monitored during the patient's stay. Specialized semi-portable monitoring instruments for obtaining and monitoring this type of health care data are part of a hospital's inventory of equipment that is assigned to individual patients on an as-needed basis and rolled into a patient's room on carts or roller stands. A large variety of semi-portable monitors are commercially provided by numerous manufacturers and distributors.
• Fully portable devices that do not require a cart or stand are also commercially available. One example of a fully portable data health care data device provided by WelchAllyn is the SPOT VITAL SIGNS™ device that allows a health care provider to take non-invasive blood pressure, pulse, oximetry, and arterial pressure data, and which may be configured with a printer for recording the data. On routine visits, or “rounds,” hard copy recordings of health care data obtained from such devices may be periodically printed and included in the files to create a vital signs history. Alternatively, the health care provider may manually record such data in the file with time and date information.
• In the past, day-to-day patient intake and monitoring information was exclusively hand recorded in a paper file by a variety of health care provider personnel. Today, health care institutions are increasingly moving toward recording health care information in electronic patient files rather than in hard-copy files. In typical electronic file systems, patient files are maintained on a centralized computer system and patient information and health care data are entered from a variety of distributed smart terminals positioned in intake rooms, examination rooms and hospital rooms. The smart terminals serve as a substitute for the hard copy files, permitting the variety of health care providers to enter and display a variety of health care information from a variety of locations without need for physically transferring the hard copy file.
• Another improvement in recent years is that monitoring devices have been equipped with telemetry equipment to wirelessly upload health care data through a network of receivers that are positioned remotely from the monitors. In certain situations, such as with ambulatory patients requiring continuous monitoring of specific vital signs, or with ambulance patients being transported to a hospital under emergency situations, small, portable monitors with self-contained power and data telemetry units are used to continuously record and transmit health care data to a centralized computer system. Commercially available examples of such portable monitors are exemplified by the Micropaq™ and Propaq™ monitors provided by WelchAllyn. These monitors display ECG waveforms, heart rate, invasive or non-invasive blood pressure, temperature, pulse oximetry and respiratory data. In certain optional configurations, these devices can wirelessly transmits such data over a local area wireless radio frequency network (FlexNet™). In other optional configurations, data assimilated by the monitors may be transmitted via infrared data transmission.
• While the provision of centralized electronic patient record files and portable health care data monitors equipped with telemetry options has improved the ease and efficiency of collecting, transmitting and storing health care data, there remains a need in the art to equip a health care provider with options for integrating the collected data with patient identification information, and for providing for additional types of data that can be collected using an inexpensive and fully portable device.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
• As used herein, “health care data” is the meaningful form of data, including at least in-part, data commonly known as “vital signs” that pertain to the health of a patient. Typical types of health care data include, but are not limited to, temperature, pulse, blood O₂level, electro cardiogram data, blood pressure, respiratory rate, appearance (such as may be recorded by a camera), sound information (such as obtained by a stethoscope) and the like.
• The term “patient identifying data” refers to data that can be used to identify a patient. Typical types of patient identifying data includes name, age, sex, and insurance information.
• The term “signal data” refers to the raw signal that is received from a health care data assimilation device before the raw signal is converted into meaningful health care data by the action of a microprocessor. Typically, signal data is in the form of an amplitude or a frequency of a voltage, a current, or optical analogues of the same, which has been transduced from a detector that detects changes in pressure, light, sound, temperature or other measurable attribute.
• The term “associated with” as used with respect to a component part of the health data tool (described in more detail hereafter) means that the component part is physically stored in, attached, or coupled or connected to the health data tool. The attachment or connection may be fixed or removable.
• FIGS. 1 and 2, illustrate front and rear isometric views, respectively, of one embodiment of ahealth data tool10 of the invention. Thehealth data tool10 includes ahousing12 that houses a plurality ofdata assimilation devices40,42,44,48,50,57 associated withhealth data tool10. Thehousing12 includes alower handle14 portion, which in advantageous embodiments, extends longitudinally downward with respect to afront display surface13 of thehousing12. Thehousing12 is configured to be of shape, size and weight to permit thehealth data tool10 to be held in one hand of health care provider. In typical embodiments, thehousing12 is made of a plastic material and occupies less than about 2 or less than about 1 cubic feet of space and weighs less than about 10 pounds, less than about 5 pounds or less than about 3 pounds. The downwardly extendinghandle14 and overall configuration of thehealth data tool10 permits a health care provider to hold thehealth data tool10 in one hand while manipulating data assimilation devices with the other hand and simultaneously observing data that is displayed on adisplay screen22 located in anupper portion15 of thehousing12. Thedata assimilation devices40,42,44,48,50,57 and thedisplay screen22 are described in more detail hereafter.
• In certain embodiments, the downwardly extendinghandle14 is configured with anaccess door9 that provides access to ahollow compartment11. Thehollow compartment11 may be used to store one or more of the data assimilation devices. In the embodiment depicted inFIG. 1, thehollow compartment11 in thehandle14 enclosesbatteries13 used to power thehealth data tool10 and, optionally, one or more of the data assimilation devices associated therewith. As depicted inFIG. 1, thehollow compartment11 also houses asmall air compressor16 used to supply air through an air line17 for automatic operation of a non-invasiveblood pressure cuff44. Of course, the batteries orair compressor16 may be located elsewhere in thehousing12 so long as suitable electrical connections or tubing is provided to power thehealth data tool10 and channel air flow to the air line17. Theair compressor16 is not needed when theblood pressure cuff44 is configured for manual inflation using a bulb.
• Thehealth data tool10 includes acode reader20 associated with thehousing12 to read information pertaining to the patient. In advantageous embodiments, thecode reader20 is integrated into thehousing12, although in other embodiments thecode reader20 may detachably coupled to thehousing12. The function of thecode reader20 is to read coded information associated with or pertaining to the patient. The coded information typically includes personal information that identifies the patient and may also include information pertaining to drugs or devices that are to be administered or otherwise used in treating or monitoring the patient.
• In one exemplary embodiment, thecode reader20 is a standard bar code reader. Typically, during an intake procedure at a health care facility a patient to be treated or admitted is supplied with anidentity tag46, usually in the form of wrist bracelet, that includes the name of the patient, the date of admission, the administering health care provider or other information such as insurance provider and the like. Some or all of this information may be encoded in abar code47 on theidentity tag46. Thebar code reader20 permits this identifying information to be rapidly and accurately entered into thehealth data tool10.
• The patient may also be prescribed a drug therapy that includes a name for the prescribed drug, a dosage and frequency of administration. In certain cases the patient may bring a drug container to a health care provider upon admission to a health care facility to assist in diagnosis or treatment, while in other cases the health care provider at the facility may prescribe a drug treatment to the patient. Such prescription information, or parts thereof, may also be encoded in a bar code associated with the container that contains the drug. Thebar code reader20 permits the health care provider to enter the relevant drug information into thehealth data tool10. Similarly, an admitted patient may be assigned usage of various medical devices from an inventory of devices provided by the health care facility. These medical devices often include a bar code to identify the particular device for tracking, performance monitoring and inventory purposes. Thebar code reader20 allows the health care provider to associate a given medical device with a given patient identification in a memory record to facilitate these purposes.
• While thebar code reader20 may be the most universally adopted form of acode reader20, it is understood that that many other embodiments of thecode reader20 may be associated with thehealth data tool10 to provide the same or similar functions. Another embodiment of thecode reader20, for example, is a “dot” reader that scans a pattern of dots that encode information. Another embodiment is an optical character recognition scanner that scans an image in bit form and then converts the scanned image into alphanumeric characters. Another embodiment is a magnetic strip reader that extracts information magnetically encoded on a data strip. Yet another embodiment is a radio frequency (RF) receiver that receives electromagnetic waves transmitted from an RF identification tag in which information regarding the subject is encoded. Sill another embodiment of thecode reader20 is a hologram reader that detects spectral or diffraction patterns emitted by an illuminated hologram and extracts information encoded therein form the pattern of spectral or diffraction patterns detected. Accordingly, the skilled person will understand that thecode reader20 can be embodied in many forms and with many variations, as long as thecode reader20 permits information to be extracted from a tag, card or other identifying device associated with a subject patient (or thing).
• Turning now to thedata assimilation devices40,42,44,48,50, and57, in various embodiments, the data assimilation devices associated with thehealth data tool10 include at least two different instruments for measuring health care data from a patient. Example data assimilation devices include, but are not limited to, a pulse oximeter (SPO2 meter)42 for measuring pulse rate and oxygen saturation of the blood, a thermometer such astympanic thermometer40 for measuring a patient's temperature, a non-invasiveblood pressure device44 that includes a blood pressure cuff for measuring blood pressure, anelectronic stethoscope48 for detecting interior sounds from the patients body, and a “two finger”electrocardiogram device57 or an ECG lead wire set50 for recording cardiac activity thorough finger electrodes. In some advantageous embodiments, thehealth data tool10 also includes adigital camera28 as a data assimilation device integrated within thehousing12 for recording digital pictures of the patient.
• Thehousing12 of thehealth data tool10 also includes one or moredevice input ports27,29,3133, and34 configured to receive data output from the data assimilation devices.40,42,44,48,50, and57. In certain examples, theinput ports29,31 and33 are particularly configured to receive output from the data communication lines of particular data assimilation devices such as thestethoscope48, theECG50 and theblood pressure cuff44, respectively. Bloodpressure input port33 may be further configured for delivering air pressure to theblood pressure cuff44 through air flow line17 and to receive data from theblood pressure cuff44 throughdata input line19. Theinput ports34 may also be configured to receive data output from the ECG lead wire set50. Theinput port27 is a standard two-way input/output computer interface port that receives a standard computer data communication cable, such as for example, a USB cable. Various commercially available data assimilation devices, exemplified by theSPO2 oximeter42 depicted inFIG. 1, may be pre-configured or adapted to output data over such standard computer cables. One advantage of the two-way input/output port27 is that it can be used to receive data from the data assimilation devices in one operational mode of thehealth data tool10, and used as a data transmitter or receiver port in another operational mode where the health care data is uploaded or downloaded into a remote computer system as will be described in more detail hereafter.
• As illustrated inFIG. 2, thehousing12 also includes one or more storage compartments16 and19 for storing the data assimilation devices associated withhealth data tool10. Thestorage compartment16 is an open slot configured for storing theblood pressure cuff44 folded or rolled into a size that slips into theslot16. Thestorage compartment19 is configured to store one or more smaller data assimilation devices, exemplified inFIG. 1 bySPO2 pulse oximeter42. The interior ofstorage compartments16 or19 may optionally be equipped with clamps, hooks, Velcro™ orother latching mechanism21 for securely holding the data assimilation device within thestorage compartment16 or19. In addition, or alternatively, thestorage compartment19 may be configured with adoor18 for enclosing the interior of thecompartment19 with the stored data assimilation device. Thedoor18 in various embodiments, may be sliding door, a swinging door, or a removable door.
• FIG. 3 illustrates another configuration of thehealth data tool10 and depicting other locations ofvarious storage compartments19aand19bwithcorresponding access doors18aand18b,which are located on side edges of theupper portion15 of thehousing12.Storage compartment19cwith slidingdoor18cis located on theupper surface13 of the health data tool along with thedisplay screen22.Storage compartment19dwithcorresponding access door18dis located on the back side of downwardly extendinghandle14. Accordingly, the storage compartments16 and19 may be located anywhere in thehousing12 where there is room to accommodate a compartment without making the overall dimensions of thehealth data tool10 too large to be comfortably handled by a health care provider.
• The storage compartments16 and19 represent one example embodiment of means to associate the data assimilation devices with thehealth data tool10 of the invention. Other means are also available. For exampleFIG. 4 is a side view of an alternative means for associatingdata assimilation devices44 and87 with thehealth data tool10. In this embodiment, a thermistortype temperature probe87 that is separate from thetympanic thermometer40 is releasably inserted into areceptacle89 situated in thehandle14 of thehousing12. Thetemperature probe87 is secured within, and released from, thereceptacle89 by means of closing and opening alatch mechanism90 provided on the bottom of thehandle14. Also in this embodiment, instead of using aslot16 orcompartment18 to store theblood pressure cuff44, thecuff44 is rolled and banded with an elastic orVelcro TM band79. Theband79 is attached to aflat spring clip81 configured to be inserted into aspring receptacle83 that securely holds theblood pressure cuff44 in place on thehandle14 of thehealth data tool10 by the tension of thespring clip81 against the wall and ledge of thespring receptacle83. Theblood pressure cuff44 is released from thespring receptacle83 by operation ofspring release mechanism85, which compresses theflat spring clip81 thereby releasing the tension of the spring from the walls and ledge of the receptacle.
• Referring again toFIG. 1, in some advantageous embodiments, thehealth data tool10 optionally includes amicrophone54 for collecting sound information. The sound information may include for example, oral notes made by a health care provider or patient or sounds emitted from the patients body, such as the sound of a heartbeat, organ function or flow of blood.Specialized microphones54aor54bmay be configured with thestethoscope48 or theblood pressure device44 to amplify the sound of the patient's heartbeat, organ function or blood flow. Aspeaker56 and associated amplifier (not shown) may optionally be associated with the health data tool to audibly emit the sounds received from themicrophones54,54aor54b.
• Thefront surface13 of thehealth data tool10 also includesinput keys24 for selecting various functions to be executed by thehealth data tool10. Theinput keys24 may be touch-screen type input keys as depicted inFIG. 1 or conventionaltoggle input keys24 integrated into thehousing12 separately from thedisplay screen22, as depicted inFIGS. 3-6. Thedisplay screen22 is configured to display a plurality of different types of health care data obtained by the data assimilation devices and to display commands or status information selected by theinput keys24. In various embodiments thedisplay screen22 displays wave form data, alpha numeric data and/or image data.
• In an example use, input key24ais depressed to select a particular data assimilation device to acquire health care data. A name or other designation of the selected device is initially displayed on thedisplay screen22 to verify the selection. Toggling of the input key24A sequentially displays the name of different input devices. The selected device is activated by the health care provider and thehealth data tool10 is set to acquire and display the selected type of data by depressing enter key24B. Alternatively, theinput ports27,29,31 and33 may be configured with a plug-and-play type of switch to automatically set the health data tool for acquiring data from a particular data assimilation device when that device is plugged into the appropriate input port. The health care provider then withdraws the necessary data assimilation device from its storage location in thehousing12 and, in the case of data assimilation devices such as the blood pressure cuffs44, theSPO2 pulse oximeter42 orfinger ECG electrodes57, dons the instrument on the patient. Alternatively, in the case of data assimilation devices such as thestethoscope48,thermometer40, orcamera28, the health care provider situates the instrument in the appropriate location to acquire the health care data.
• Once donned or situated, the health care provider presses input button24c to begin acquiring the health care data. In the case of acamera28, the selection of that device activatestrigger25 to function as a shutter release so that when thetrigger25 is depressed, the camera takes a photo. In any case, the acquired data is displayed ondisplay screen22 in the appropriate form for the selected device. For example, if the selected data assimilation device is the two-finger ECG57 or ECG lead wire set50, then the wave form of the electrocardiogram signal is displayed on thedisplay screen22. If the selected data assimilation device is ablood pressure device44, then the systolic and diastolic readings are displayed in alphanumeric form on thedisplay screen22. Similarly, if the selected data assimilation device is athermometer40, then an alphanumeric representation of temperature is displayed as it is being collected. If the selected device is thecamera28, then the recorded digital image is displayed on the display screen.
• Thehealth data tool10 is optionally equipped with aspeaker56 associated with thehousing12. If the selected data assimilation device is astethoscope48, then the sound detected through thestethoscope microphone54ais amplified and emitted through thespeaker56 to permit the health care provider to listen to the sound and readjust the position of the stethoscope as needed. Optionally, when thestethoscope48 is selected, depressing input key24c activates trigger25 to cause thehealth data tool10 to operate in record mode so that if a recording is desired, depressing the trigger25 a first time begins the process of taking a digital sound recording and depressing the trigger25 a second time ends the recording. Similarly, if the selected data assimilation device is a voice record, then depressing input key24c activatesmicrophone54 to receive voice information and activatestrigger25 to function in record mode. Depressing the trigger25 a first time begins the process of taking a digital voice recording and depressing the trigger25 a second time ends the voice recording. In certain embodiments, the health data tool may also include a microprocessor programmed with voice recognition software to translate the sound recording into alphanumeric text.
• When the data is a sound recording, ECG output, or other time-dependent data, such data is digitally recorded for a time period that in one embodiment, is selected by the health care provider. When such time dependent data assimilation devices are selected, input key24E may be used to select the time period of the recording to store. In an alternative embodiment, the time period of the recording is the same as the time period that results from depressing theinput trigger25 on and off as described above. Alternatively, thehealth data tool10 may be pre-preprogrammed to record and/or store particular types of health care data for a predetermined increment of time. For example, thehealth data tool10 may be pre-programmed to record and store ECG data for a period of60 seconds and to record and store stethoscope data for a period of10 seconds.
• The operation of the various input keys24A-24E and trigger25 described above is for exemplary purposes only. One of ordinary skill in the art will recognize that theinput keys24 can be programmed to perform the functions of thehealth data tool10 in a variety of configurations. For example, even asingle input key24 can be configured with programming to select functions from a menu of options displayed on thedisplay screen22. Similarly, the functions of thetrigger25 can be accomplished using aninput key24. Accordingly, any arrangement ofinput keys24 that allows the health care provider to operate thehealth data tool10 to perform any of the functions described herein is suitable for the invention.
• Furthermore, the embodiments of thehealth data tool10 are described above as functioning in a sequential data assimilation mode, whereby one type of data assimilation device is activated at a time. In other advantageous embodiments, multiple data assimilation devices can be selected to simultaneously acquire different types of health care data, in which case thehealth data tool10 functions as a multimeter, simultaneously acquiring and displaying a plurality of different data. In such embodiments, multiple devices are selected by sequentially depressing select input key24aand enter key24b.Thedisplay screen22 initially displays each selected device in a list when entered. In one embodiment illustrated inFIG. 2, when acquire input key24cis depressed, thedisplay screen22 is activated to display the different types of data on divided portions of thesame display screen22. Alternatively,multiple screens22 are used to display different data on different types of screens. In such embodiments, simple alphanumeric data may be displayed on simple low resolution LED display screens, while more information intensive data such as wave form data or image data is displayed on a field emission, plasma, or other type of high resolution display screen.
• In advantageous embodiments, thehealth data tool10 is also equipped with anelectronic memory60 to store patient information and the health care data assimilated through the various data assimilation devices associated with thehealth data tool10. As depicted inFIG. 1, thememory60 is shown as a removable memory card, such as a flash memory card, that is inserted intomemory slot61. However, it is understood that thehealth data tool10 may be configured with another type of memory such as conventionalelectronic memory60 integrated within thehousing12. In an example operation, depressing store data input key24d functions to store the health care data in thememory60. Alternatively, thehealth data tool10 may be programmed to automatically store the data inmemory60 when acquisition is complete. In an advantageous embodiment, the data is stored in a record structure associated with the patient identification information acquired usingcode reader20. In certain embodiments, date and time information is automatically provided in the record, and time information is supplied from a clock (not shown) associated with thehealth data tool10.
• In further advantageous embodiments, thememory60 stores a plurality of health care data records for a plurality of patients in a database structure. In such embodiments, the health care provider can acquire multiple records from multiple patients, or for the same patient, over the course of a shift and later upload the recorded information into a centralized database on aremote computer80, as depicted inFIG. 5, that stores patient records as will be described more fully hereafter.
• In certain advantageous embodiments, thehealth data tool10 is also equipped with one or moredata transmission devices21 and/ordata receiver devices26. In one embodiment, thedata transmitter21 orreceiver26 device is a wireless data transmission device. Example wireless data transmission and receiver devices suitable for the invention include, but are not limited to, infrared and radio frequency transmitters and receivers. Thedata transmitter21 is used to upload data stored in thememory60 of thehealth data tool10 into theremote computer system80 via transmission of the data to remote infrared data or RF receiver. Thedata receiver26 is used to receive an input of data into thehealth care tool10 from a remote wireless data transmitter. Such remote transmitters and receivers are typically situated in individual rooms where the patient is located, in which case the data can be transmitted or received simultaneously in a given patient's room. Alternatively, these remote transmitters and receivers may be located in a central location where multiple data records for multiple patients may be uploaded or downloaded in a single session. Data transmission or reception is accomplished either automatically or by selecting a transmit or receive function from one of theinput keys24, which in certain embodiments, activatestrigger25 to function to initiate data transfer.
• Another embodiment of a data transmission and receiver device is the computer input/output port27. An appropriate data communication cable is attached to the input/output port27 and to an input/output port for the central computer system. An advantage of using a standard computer interface cable is that is adaptable for use with any modifications, upgrades or other changes that are made to thehealth data tool10 or theremote computer system80.
• Data transfer to theremote computer80 may also be accomplished usingdocking port51. Thedocking port51 is specifically configured to plug thehealth data tool10 into adata transfer port53 situated in adocking station65 as depicted inFIG. 5. Thedocking station65 has apower supply cord67 and outputs to adata transmission line69 for transferring data between theremote computer system80 and thedata tool10. In addition, thedocking station65 may include abattery recharging port70 adapted to fit into rechargingreceptacle71 in thehealth data tool10 for recharging thebatteries13 housed therein. Thedocking station65 may also include a keyboarddata receiver port39, which may be an infrared data port or cable type of port. Textual data may then be entered and stored into memory in thehealth data tool10 viakeyboard38 that transmits the data either through thewireless receiver21 associated with thehealth data tool10 or through thedata receiver port39 associated with thedocking station65. In an exemplary practice, input key24e is toggled to select a patient record stored intomemory60. Input select key24ais toggled to select “text” data. Thehealth data tool10 is then activated to receive data entered from thekeyboard38, which is displayed in text format onscreen22 and ultimately transmitted to theremote computer system80 with the other patient record data stored in thememory60 of thehealth data tool10.
• The electronics required to operate thehealth data tool10 are located within thehousing12. The electronics include a microprocessor that is programmed to perform the various functions described above for thehealth data tool10. The operating electronics contains conventional busses, clocks, and logic necessary for communication between the microprocessor, the various data assimilation devices and the memory. The operating electronics also include the required circuitry for operating thedisplay screen22 responsively to the data output.
• In certain embodiments, the data assimilation devices associated with thehealth data tool10 contain separate microprocessors for converting the raw signal detected by transducers in the data assimilation devices into meaningful health care data. In these embodiments, only the converted health care data is input into thehealth data tool10, thereby simplifying the electronics and lowering the cost of manufacturing thehealth data tool10. These embodiments are adaptable for a wide variety of data assimilation devices now in existence or yet to be devised.
