Description

Portable low-cost multichannel ECG monitor

Technical field:

This utility model relates to a kind of portable low-cost multichannel ECG monitor, belongs to the person monitoring Instrument technology field.

Background technology:

In the last few years, with the increase of aged tendency of population degree, the sickness rate of cardiovascular disease was in rising trend, had become to cause main causes of death with the quickening pace of modern life.Various countries' medical circle is paid much attention to the diagnosis and the treatment of cardiovascular disease; The world a lot of Medical Instruments company has all dropped into great amount of manpower and material resources and has carried out the development and the exploitation of Related product, and has formed from bedside monitoring, remote measurement and guard until a series of cardiac monitoring products such as central monitorings.Developing rapidly of while Along with computer technology, relevant intelligent diagnostics software emerges in an endless stream, and the theory of cardiac monitoring and intelligent diagnostics has developed into the comparatively sophisticated stage.The monitor that exists at present is used for the special medical institutions that scale is arranged more, and is bulky, cost an arm and a leg, and is not suitable for family and small medical mechanism and uses.Also have some portable ecg monitors inventions, but also come with some shortcomings, what can not solve accurate, portable, inexpensive can continuous record and problem such as analysis of cardiac activity.

Summary of the invention:

For overcoming the defective of prior art, the purpose of this utility model is to provide that a kind of measurement is accurate, easy to carry, low price, can continuous recording domestic ECG monitor.

This utility model technical solution problem adopts following technical scheme:

Portable low-cost multichannel ECG monitor, it comprises ecg signal acquiring device and the single-chip microcomputer that is electrically connected with said ecg signal acquiring device;

Said ecg signal acquiring device comprises electrocardio amplifying circuit, electrocardio filtering and the D/A converter module of mutual electrical connection;

Said single-chip microcomputer also is electrically connected with LCDs, alarm module and memory module.

The construction features of this utility model also is:

Said electrocardio amplifying circuit and electrocardio filtering multichannel are connected in said D/A converter module side by side, and said D/A converter module is electrically connected with said single-chip microcomputer.

Said memory module comprises outer extension memory and address latch, and the abnormal electrocardiogram signal that said memory module is judged said single-chip microcomputer is stored.

Compared with present technology, the beneficial effect of this utility model is embodied in:

The portable low-cost multichannel ECG monitor of this utility model can be measured one or more patients' electrocardio situation simultaneously; Setting recording precision as requested; With the operation of simple and direct graphical interfaces, independently judge abnormal cardiac rate and record, supply medical personnel's analyze the state.This instrument can be used lithium battery power supply.

In the configuration design, shell adopts rigid plastics, safety anti-vibration, and size is easy to carry as regular handset.A color touch screen, attractive in appearance and easy operating are selected in demonstration and operation for use.Terminals adopt plug type.This utility model cost is low, and is practical, is easy to promote at average family and small medical mechanism.

Description of drawings:

Fig. 1 is the schematic appearance of the ECG monitor of this utility model.

Fig. 2 is the functional block diagram of the ECG monitor of this utility model.

Label among the figure: 1 single-chip microcomputer, 2 electrocardio amplifying circuits, 3 electrocardio filtering, 4 D/A converter modules, 5 LCDs; 6 alarm modules, 7 outer extension memories, 8 address latchs, 9 shells, 10 port options buttons; 11 accuracy selection keys, 12 on & off switches, 13 leads, 14 terminals.

Below pass through the specific embodiment, and combine accompanying drawing that this utility model is described further.

The specific embodiment:

Embodiment: shown in Figure 2, the multichannel ECG monitor of present embodiment, it comprises ecg signal acquiring device and the single-chip microcomputer 1 that is electrically connected with the ecg signal acquiring device; The ecg signal acquiring device comprises electrocardio amplifying circuit 2, electrocardio filtering 3 and the D/A converter module 4 of mutual electrical connection; Also be electrically connected with LCDs 5, alarm module 6 and memory module with single-chip microcomputer 1.

Shown in Figure 2, electrocardio amplifying circuit and electrocardio filtering multichannel are connected on the D/A converter module 4 side by side, and D/A converter module 4 is electrically connected with single-chip microcomputer 1.

Memory module comprises outer extension memory 7 and address latch 8, and the abnormal electrocardiogram signal that said memory module is judged single-chip microcomputer is stored.

Shown in Figure 1; In specifically being provided with; ECG monitor comprises that tool housing 9, LCDs can show heart rate, the heart rate normally whether first result of declaring, heart beating signal sign, heart rate curve display etc.; Can select display precision but 10 final elections of port options button, accuracy selection key 11 are connected with single-chip microcomputer, Instrument shell is provided with on & off switch 12, and multiple conducting wires 13 connects the electrocardio amplifying circuit respectively through terminals 14.

When using, select power supply mode according to environment for use earlier,, can select the power supply of inner lithium electricity if carry if indoor many people of monitoring electrocardio can be selected externally fed.With lead 13 monitored object heart rate sample point is linked at terminals 14 places; Open on & off switch 12; Whether select port options button 10 and accuracy selection key 11 as requested, will show the electrocardiogram, heart rate of detected object on the display screen, just declare is relevant information such as normal.

On the principle, with the electrocardiosignal of body surface through amplification, after the filtering, by the interfering signal beyond the filter circuit filtering electrocardio; The digital signal that will pass through after the digital-to-analogue conversion is input in the single-chip microcomputer by the serial port of single-chip microcomputer, and single-chip microcomputer is through programming, and normal electrocardiosignal is sampled and extracted eigenvalue; Compare with the electrocardiosignal of real-time sampling; Normal to judge whether, undesired will the warning, and undesired signal stored through address latch, outer extension memory.
