Abstract

Disclosed is a household multifunctional electrocardiograph, belonging to the field of medical apparatus and instruments. It is composed of a lead, an electrocardiograph, and an emission part. An infrared receiving unit is arranged in the close range of the emission part, and the infrared receiving unit is directly connected with a computer. The front part of the emission part is the lead, which after being amplified by a triple pole and then conversed by an A/D, changes measured analog signal of human into digital signal and then inputs the digital signal into a single-chip computer. After being emitted in the end by an infrared modulator connecting with an infrared sensor in the close range of the emission, the digital is received and delivered to the computer, being displayed or printed out. The household multifunctional electrocardiograph has advantages of simple structure, simple manufacture and less expensive price, and is mostly characterized in that it is fit for family use, very easy in use, having great social benefit and economic benefit.

Description

The multifunctional domestic electrocardiograph

Technical field

This utility model belongs to technical field of medical instruments, is adapted at family patient diagnosis is used.

Background technology

At present, EGC detecting Instrument that sell on the market or that hospital uses is varied, common feature is exactly an advanced technology, multiple functional, stable performance, it is also comparatively convenient to operate, but its weak point is a complex structure, function singleness, cost an arm and a leg, mostly be employed in the electrocardiographic room of medical institutions at different levels, and will be by special medical worker's operation, inconvenience family uses, the electrocardiogram detector can be divided into three major types by its function at present, first electrocardiogram class, being used to do twelve-lead electrocardiogram uses, it two is the electrocardiogram monitor class, and this machine is used for clinical monitoring, and it is dynamic to be fit to the monitoring patient's heart, at last a kind of is the dynamic ecg class, be mainly used in and measure patient's active state, as electrocardiogram situation of change under the rest state, in sum, each can only finish simple function three class electrocardioscanners, electrocardiograph can only be drawn the electrocardiogram of short time, can not adopt for a long time; Electrocardiogram monitor can be adopted figure for a long time, but does not have memory function, detects the ambulatory electrocardiogram function; Dynamic ecg does not have the cardiac monitoring function, and so electrocardiograph uses for the patient's of family diagnosis makes troubles.

Summary of the invention

For solving the deficiency of above-described electrocardiograph function, the purpose of this utility model provides a kind of multi-functional electrocardiograph, utilize electrocardiograph sampling back to send with infrared transmitter, infrared receiving set receives, and the reuse computer output information is to reach the purpose that family uses.

The structural design of this utility model is achieved in that home-use its structure of multi-functional electrocardiograph comprises emission, receives two parts (as shown in Figure 1), wherein radiating portion is by leading and electrocardiograph is formed, receiving unit is made up of infrared accepter and computer, its connection is to lead to be crosslinking electrode, contact received signal with human body, connect symmetrical amplifier, symmetrical amplifier output connects difference amplifier, difference amplifier output connects single-ended input amplifier, and amplifier output is connected with the single-chip microcomputer input through A/D converter; Amplifier output simultaneously connects with single-chip microcomputer through analog memory, with emitter infrared remote receiver is housed closely, and receptor directly connects with computer, special-purpose software is housed in the computer, human body signal is imported computer indirectly, behind date processing, with diagnostic result output (as shown in Figure 2).

The advantage of this utility model: the multifunctional domestic electrocardiograph, simple in structure, make simple and easyly, cheap, maximum characteristics are adapted at family and use, and are extremely easy to use, have very big social benefit and economic benefit.

Description of drawings

Fig. 1 is a multifunctional domestic electrocardiograph structure principle chart;

Fig. 2 is a multifunctional domestic electrocardiograph electrical schematic diagram.

The specific embodiment

This utility model detailed structure and operation principle are illustrated in conjunction with the accompanying drawings.

Its structure as shown in drawings, crosslinking electrode connects electrocardiograph, triode amplifier is housed in the electrocardiograph to transmit, receptor connects computer by infrared remote receiver, the physical circuit front end is a crosslinking electrode, the crosslinking electrode front end contacts with human body, the outfan of crosslinking electrode, connect symmetrical amplifier two inputs respectively through the resistance-capacitance coupling balancing circuitry, and amplifier output connects the positive-negative input end of difference amplifier respectively through resistance, output one end of this difference amplifier is coupled in parallel to negative input end through capacitance-resistance, export simultaneously through electric capacity, the resistance coupling is input to the positive input terminal of single-ended amplifier, outfan is connected to A/D converter, output to analog memory and single-chip microcomputer again simultaneously, amplifier out send A/D converter, the analog quantity that amplifier is produced converts digital quantity to, send into single-chip microcomputer, single-chip microcomputer receive data after infrared modulator after driving amplifier launch, be connected to computer with the in-plant infrared remote receiver output of the emitter in the electrocardiograph by interface circuit, be used as heart patient diagnosis foundation with software processing result demonstration and printer at last.

Claims

1, a kind of multifunctional domestic electrocardiograph, it is characterized in that this electrocardiograph structure comprises emission, receives two parts, wherein radiating portion is by leading and electrocardiograph is formed, receiving unit is made up of infrared accepter and computer, and its connection is to lead to be to contact received signal with human body by crosslinking electrode, connect symmetrical amplifier, symmetrical amplifier output connects difference amplifier, and difference amplifier output connects single-ended input amplifier, and amplifier output is connected with the single board computer input through A/D converter; With emitter infrared remote receiver is housed closely, receptor directly connects with computer, and memorizer and external equipment display and printer are housed in the computer, and special-purpose software is housed in the computer, human body signal is changed over to indirectly to computer behind date processing, diagnostic result is exported.
