Abstract

The invention relates to an electrocardiogram collection device with a patient measuring state alarming function. On the basis of a conventional electrocardiograph, an acceleration sensor is integrated in the electrocardiogram collection device, and an algorithm for judging body instability is matched. When electrocardiogram of a patient is measured and measured electrocardiogram is inaccurate due to the fact that movement of the body exceeds a specified range, the electrocardiogram collection device can automatically remind the patient of maintaining stability of the body and keeping calm and can automatically neglect the currently measured electrocardiogram.

Description

A kind of electrocardiogram harvester with patient's measuring state warning function

Technical field

The present invention relates in medical instruments field, a kind of electrocardiogram harvester with patient's measuring state warning function.

Background technology

At present, electrocardiograph starts to become portable, intelligent, and starts to progress into every family, becomes civil nature by hospital's special equipment.Patient can carry out Electrocardiographic measurement in own home.Such as hand-held electrocardio figure machine, only has mobile phone size, and patient can measure electrocardiogram whenever and wherever possible.But hand-held electrocardio figure machine also has problems, patient, when oneself measures electrocardiogram, owing to not lacking experience, if do not keep body balance, will cause ecg measurement inaccurate.

Summary of the invention

The present invention proposes a kind of electrocardiogram harvester with patient's measuring state warning function, object is when allowing patient measure electrocardiogram, if health has the motion exceeding prescribed limit, cause the electrocardiogram of measurement inaccurate, can patient be automatically reminded to keep body balance, the tranquil gas of the heart, and automatically ignore current measured electrocardiogram.

System construction drawing of the present invention is as shown in Figure 1:

System structure comprises: electrocardioelectrode 1001, electrocardiogram acquisition circuit 1002, microprocessor 1003, key-press input 1004, state display 1005, acceleration transducer 1006, speaker 1007, correspondence with foreign country circuit 1008.

In system, the interconnecting relation of each several part is:

The electrocardiosignal that electrocardioelectrode 1001 gathers is transferred to electrocardiogram acquisition circuit 1002, electrocardiogram acquisition circuit carries out filtering, amplification to electrocardiosignal, by Signal transmissions to microprocessor 1003, microprocessor carries out secondary filtering process to signal, is transferred to other equipment or uploads the Internet by correspondence with foreign country circuit 1008.Button inputting circuits 1004 connects microprocessor 1003, the operation signal of input patient.Status display circuit 1005 connects microprocessor 1003, and some comparison state informations of display electrocardiograph, also can show Electrocardiographic real-time waveform.Acceleration transducer 1006 connects microprocessor 1003, by the acceleration of motion input microprocessor 1003 of human body.Speaker 1007 is connected with microprocessor 1003, can send prompting to patient.

Wherein, acceleration transducer 1006 may have one or more.

Wherein, the analog digital conversion (analogue signal aims at digital signal) of signal may be carried out in electrocardiogram acquisition circuit 1002, also may carry out analog digital conversion in microprocessor 1003.

Correspondence with foreign country circuit 1008 can be wire communication or radio communication, and wire communication is as USB, serial ports, CAN, Ethernet etc., and radio communication such as the 2G/3G/4G of bluetooth, Zigbee, Wifi, mobile operator communicates.

The operation principle of major function of the present invention:

Ecg signal acquiring is not main points of the present invention, does not explain at this.Acceleration transducer gathers the acceleration of motion of human body, be transferred to microprocessor 1003, microprocessor reads primary acceleration value every a time slot t (as t=1 millisecond) and stores, in certain time interval T (as T=2 second), form the array (as t=1 millisecond, T=2 second, then totally 2000 acceleration value in array) of an accekeration, calculate the standard deviation of this array, as standard deviation exceedes threshold value M (as M=0.5 meter per second²), then think in time T, the balance degree of patient is inadequate, and this section of ecg wave form may be interfered and inaccurate, and propose alarm to patient, prompting patient keeps body balance, ignores the figure of this period simultaneously.

If the comprehensive lead electrocardiogram machine of hand-held, electrode is together with electrocardiograph, then acceleration transducer is built in electrocardiograph.If adopt conducting wire to connect the pole piece of health, then acceleration transducer is integrated in one section that electrode lead wire connects electrocardio pole piece.Lead if multiple, then the integrated acceleration transducer of each limb lead electrode, chest lead only needs an integrated acceleration transducer on a crosslinking electrode.

When there is multiple acceleration transducer, the data of each acceleration transducer are transferred to microprocessor 1003, respectively standard deviation is calculated to the data of each acceleration transducer, as long as there is one to exceed threshold value M, then report to the police, and report to the police targetedly, as found, the acceleration array standard deviation of the acceleration transducer collection on left hand electrodes exceedes threshold value M, then point out patient's left hand held stationary.Warning can be sent by speaker to patient, also can show 1005 by state and send warning to patient.

Advantage of the present invention is:

Compared with traditional electrocardiograph and the Internet electrocardiograph, the present invention can pass through Integrated Accelerometer, and patient can be reminded to keep body balance, thus improve survey Electrocardiographic quality.

Detailed description of the invention

Below in conjunction with concrete case study on implementation, the present invention is described in detail.

Embodiment one:

A kind of electrocardiogram harvester example with patient's measuring state warning function is given in Fig. 2.

In this system, the electrocardiograph of example is that hand-held comprehensively leads cardioscribe.Electrocardioelectrode of comprehensively leading 2001 is by primary signal input filter amplifying circuit 2002, then analogue signal is inputted analog to digital conversion circuit 2003, digital signal is passed through SPI (high-speed synchronous serial port) communications interface transmission to arm processor 2004, Digital ECG is uploaded the Internet by GPRS (general packet radio service technology) module by arm processor.

Have 2 buttons 2005 by " 01 " digital signal input arm processor 2004, be used for respectively gauge tap machine, start measure.Lattice lcd screen 2006 is connected with arm processor 2004 by parallel digital signal, the state of display electrocardiograph.

Acceleration transducer 2007 connects arm processor 2004 by SPI communication interface, and degree of will speed up Signal transmissions is to arm processor 2004.The comprehensive crosslinking electrode of native system is integrated in electrocardiograph casing, therefore only has an acceleration transducer 2007, is integrated in electrocardiograph casing.The accekeration of the every 1 millisecond of reading primary acceleration sensor of arm processor 2004, saves, forms array.In every 2 seconds, preserve lower 2000 acceleration informations in array, then calculate the standard deviation of this array, if standard deviation is greater than threshold value 0.5 meter per second², then think that this section of ecg wave form may be interfered and inaccurate, proposes alarm to patient, prompting patient keeps body balance, ignores the figure of this period simultaneously.

In the present embodiment, power supply is the necessary part of circuit, due to its technology maturation, and is not Core Feature of the present invention, therefore not to describe.

The implementation case is the one of the method implementation method, and details part may disagree, but not from this method scope.As analog to digital conversion circuit may be integrated in arm processor 2004, acceleration transducer 2007 can exist multiple, and situation like this, all within the scope of the invention.
