Abstract

The utility model relates to a medical diagnostic device. The outer housing of the device is provided with a lead buckle input jack, a signal output jack, a switch, etc. The lead buckle is connected with an amplifying circuit by input lines, and connected with a data processing IC, a programmable triggering logic circuit and a memory circuit. When the utility model is used, the placement of the lead buckle at a human heart enables an electrocardiogram to be recorded, and signals can be taken out by output lines connected with the electrocardiogram device. The utility model has the advantages of small size, low cost, reliable and accurate record of waveforms, etc.

Description

The short distance dynamic cardiograph

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

In recent years, in the medical diagnosis clinical practice, the heart Dynamic Monitoring is brought in constant renewal in and instrument is updated, the range of application of ambulatory electrocardiogram also enlarges day by day, the dynamic cardiograph of clinical practice has two kinds, a kind of dynamic cardiograph of forming by main frame and 24 hour record boxes, and this kind dynamic cardiograph main frame is a computer, handset is the recording box that the patient wears, and adopts magnetic recording.Another kind is exactly to adopt the data compression principle and the dynamic cardiograph that writes down, though this kind dynamic cardiograph volume is smaller, is interruption work during record, promptly writes down one section at set intervals.24 hr Ambulatory EKG Monitoring instrument are owing to adopt computer playback, printer output, and the entire machine configuration is complicated, the cost costliness of instrument, and utility ratio is very low.Because changing 24 hours electrocardio of patient, it all notes, the inevitable like this waveform of record that causes is various, the analytic process complexity, and the waveform of record disturbs big, drift is serious, must carry out date processing by computer, just can print the record result, this 24 hours whole recording methods waveform really valuable, that clinical meaning is arranged only accounts for about 5/1000ths of whole writing time.The real application of dynamic cardiograph be exactly catch when the patient is had an electro-cardiogram less than one cross the property semiography and get off, 24 hr Ambulatory EKG Monitoring instrument are because battery can only be with about 24 hours, and the length of tape can only write down 24 hours ecg informations, part patient still asymptomatic appearance in 24 hours of wearing, the result has wasted the time, also expended the Laboratory Fee of patient's costliness, and instrument costs an arm and a leg.And the dynamic cardiograph of employing data compression principle work owing to the data compression record, makes the electrocardiosignal distortion rate height of record, causes mistaken diagnosis easily, more because its intermittent recording can not be guaranteed the catch rate of abnormal electrocardiogram signal and seriality.

This utility model purpose provide a kind of volume little, need be through Computer Processing and directly not use the electrocardiograph waveform playback, short distance dynamic cardiograph easy to use, that cost is low.

This utility model is by being made up of shell body, the button that leads, signals collecting, amplification, treatment circuit, be respectively arranged with the plug fixed handle on the shell body, the button input jack leads, the signal output plughole, switch, the button that leads inserts input jack by the input line, input jack inserts amplifying circuit respectively by lead, the output of amplifying circuit inserts signal data and handles integrated circuit, its output inserts memory circuit and programmable trigger logic circuit respectively, and signal processing integrated circuit also is connected to signal and visits system logic circuit and output line; Signal data is handled integrated circuit can adopt the language sheet.

The utlity model has the computer data processing that volume is little, cost is low, need not be complicated, the patient is from line operate, only catch the abnormal symptom electrocardiogram in when outbreak, but only need just waveform playback of electrocardiograph, characteristics such as wave recording is true, clear, accurate, carry, easy to use.

Accompanying drawing 1 is this utility model appearance structure sketch map.

Accompanying drawing 2 is this utility model circuit theory diagrams.

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 button 6 that leads of transducing part inserts input jack by the input line, input jack inserts amplifying circuit 7 respectively by lead, amplifying circuit adopts the two-stage low noise, high-gain, the amplifier of high common mode inhibition is formed, have very high gain and common mode rejection ratio, capacity of resisting disturbance is strong, the output of amplifying circuit inserts signal data and handles integrated circuit 8, the date processing integrated circuit adopts large scale integrated chip, changes electrocardiosignal into digital signal, and also having simultaneously data shift signal is the function of analogue signal such as waveform, this utility model adopts the language sheet, cheap, the output of date processing integrated circuit inserts memory circuit 9 and programmable trigger logic circuit 10 respectively, and signal processing integrated circuit also is connected to signal controlling logic circuit 11 and output line.Control logic circuit produces the signal of control each several part, and clock timing, input, the required various logic of output are provided.Segment signal output takes out data by the signal memory section, is reduced to electrocardiosignal output.Above circuit is installed in the shell body 1, the plug fixed handle 2 of shell body.The input line that can fixedly lead and detain, the button plug that leads inserts jack 3, and output line inserts output plughole 4 and also inserts electrocardiograph electrocardiosignal is taken out, and this utility model is provided with switch 5 and electronic watch.Its operation principle is such, the patient will lead to detain and be fixed on cardia, when feeling that heart is not in good time, open switch, electrocardiosignal can be delivered to amplifying circuit with signal by the button that leads, data processing circuit, storage circuit etc., this utility model gets off the abnormal electrocardiogram signal record, arrives hospital then, output lead is inserted electrocardiograph, electrocardiographic wave can be taken out.

Claims

1. short distance dynamic cardiograph, be by shell body, button leads, signals collecting, amplify, treatment circuit is formed, it is characterized in that being respectively arranged with on the shell body 1 plug fixed handle 2 and buckle input jack 3 with leading, signal output plughole 4, switch 5, the button 6 that leads inserts input jack by the input line, input jack inserts amplifying circuit 7 respectively by lead, the output of amplifying circuit inserts signal data and handles integrated circuit 8, its output inserts memory circuit 9 and programmable trigger logic circuit 10 respectively, and signal processing integrated circuit also is connected to signal controlling logic circuit 11 and output line.
