Description

Household heart information storing monitor

This utility model relates to a kind of medical diagnostic equipment.

In recent years, in medical diagnosis is clinical, the wired transmission diagnostic techniques of heart dynamic remote is widely adopted, what known technology adopted is the modem transmission means, the front end monitor box is handled patient's electrocardiosignal through the long number coding after, by the telephone carrier wave main frame of Control Room is carried out signal playback again, receive, handle, when the sort signal load mode exists the main frame received signal, need to accomplish that with the front end monitor box signal is synchronous, the patient uses inconvenience, the easy distortion of signal, the mistaken diagnosis phenomenon usually appears, and cost an arm and a leg, general patient is difficult to bear economically, is not easy to penetration and promotion and civil nature and uses.

This utility model purpose provides a kind of transmission technology that adopts data bit stream, heart signal collection to the patient, handle, by the playback of telephone carrier wave, storage, printing, simultaneously also can be by the household heart information storing monitor of the direct playback of electrocardiograph.

This utility model is by the shell body of front end monitor box and internal circuit, main frame is formed, the line that leads of the internal circuit of front end monitor box inserts operational amplifier, its output inserts comparator circuit and inserts voice sheet (A/D, the D/A change-over circuit), logic control circuit output inserts the voice sheet, the oscillator circuit inserts the voice sheet behind d type flip flop, the output of voice sheet inserts memory and inserts signal modulator through behind the encoder circuit, after inserting sound intensifier, its output inserts speaker, programmable divider inserts the voice sheet, modulation circuit inserts the voice sheet, foregoing circuit is arranged in the shell body, and shell body is provided with input, output plughole and switch;

The utlity model has that structural principle is simple, dependable performance, use is easy to operate, the transmission signal is accurate, cost is low, is easy to civil nature and promotes the use of, and is widely used in characteristics such as heart disease diagnosis, monitoring in large, medium and small hospital clinical diagnosis and the family.

Accompanying drawing 1 is this utility model circuit theory diagrams.

Accompanying drawing 2 is an outer shell construction sketch map of the present utility model.

Below in conjunction with accompanying drawing this utility model is further described, structure of the present utility model and principle are to realize like this, the internal circuit of front end monitor box is provided with the line 1 that leads, the line that leads inserts operational amplifier 2, its output inserts comparator circuit 3 and inserts voice sheet (A/D, the D/A change-over circuit) 4, lead behind the patient's heart signal of gathering, be input to the voice sheet, logic control circuit 5 outputs insert the voice sheet, oscillator circuit 6 inserts the voice sheet behind d type flip flop 7, logic control circuit mainly is time and the lasting time period of writing down that control signal is gathered, the oscillator circuit provides work clock, promptly gather the frequency of electrocardiosignal, time, the output of voice sheet inserts memory 8 and inserts signal modulator 10 through encoder circuit 9 backs, the function of encoder is the machine number of establishment front end monitor box, the function of manipulator is that digital electrocardiosignal is modulated into modulation signal by digit order number, its output inserts sound intensifier 11 backs and inserts speaker 12, programmable divider 13 inserts the voice sheet, the control electrocardiosignal enters the hop count of voice sheet, modulation circuit 14 inserts the voice sheet, modulation circuit is used to control the user mode of front end monitor box, be that the front end monitor box can residing as required record, the duty of playback, foregoing circuit is arranged in the shell body 15, shell body is provided with input, output plughole 16 and switch 17, front end monitor box of the present utility model is used for the cardiac and wears with oneself, to lead and place the human heart assigned address, open the switch on the shell body, place the position of record, with the heart abnormality signal that detects by being that the internal circuit of core carries out electrocardiosignal and handles with the voice sheet, store, after the electrocardiosignal segmentation recorded, place phone to broadcast the position on switch again, utilize the bit stream transmission means and modulate, modulation circuit 14, speaker 12 transmits signals to Surveillance center by the transmitter of phone, Surveillance center is provided with electrocardiosignal receiving and processing device or computer installation, be provided with solidification software in this device, the signal that receives is handled, store and print, if the switch of front end monitor box is placed the position of putting, can be directly output lead and electrocardiograph be linked and carry out playback.This utility model has accomplished that ecg wave form is undistorted owing to adopted the transmission modulation system of digital bit stream, and diagnosis effect is good, and is easy to use.
