Abstract

The utility model relates to a medical appliance, particularly an automatic recorder for electrocardiosignals. The problems of inconvenient data process and poor reliability of the existing electrocardio-information processing group are mainly solved. The utility model has the technical proposal that the signal output end of an electrocardiograph is connected with the signal input end of a module converter through an amplifying circuit, and the signal output end of the module converter is connected with the data bus of a monolithic computer. The utility model has wide applied foreground in the field of electrocardio information process.

Description

The electrocardiosignal autographic apparatus

This utility model relates to diagnosis of Medical Instruments body surface and monitoring equipment, is specifically related to a kind of novel human ecg signal data acquisition recorder that adopts the microelectric technique design.

The electrocardiosignal autographic apparatus is a kind of desk-top solid-state data recording equipment.The electrocardio checkout equipment that generally uses of hospital clinical at home and abroad in the last hundred years, mainly based on the electrocardiograph of real time record human ecg signal, the main method of most hospitals ecg analysis still stores mode of operation based on traditional hand dipping and drawing.That traditional electrocardiogram (ECG) data measurement standard is difficult to is unified, graphic documentation is searched extremely numerous and diversely, and the development of this and modern electrocardiology and the processing data information of big specification are extremely incompatible.Though both at home and abroad large hospital is no lack of and purchases the dynamic ECG analysis system that involves great expense, i.e. Holter, its utilization rate is lower, it is simple to lead and to the analysis and the arrangement deficient function of population data.Clinical in recent years Holter and other equipment of having proved already can not replace the conventional ECG inspection.Therefore construct the existing electrocardiograph of a kind of utilization and be front end processor, single-chip microcomputer is a harvester, and micro computer is a kind of rational design of can yet be regarded as of the scheme of analytical system.Adopt this monitor can make person under inspection's electrocardiogram be able to systematically intactly preserve, analyze, thereby for clinical Electrocardiographic analysis and application provide simple and direct means rapidly, for the doctor correctly discerns person under inspection's electrocardiogram and historical ground analysis and summary person under inspection's situation provides objective foundation.

The purpose of this utility model is to provide a kind of dependable performance, the strong electrocardiosignal monitor of the suitability.

The technical solution of the utility model: the signal output part of electrocardiograph connects the signal input part of analog-digital converter through amplifying circuit, and the signal output part of analog-digital converter connects on the data/address bus of single-chip microcomputer.

Advantage of the present utility model: so handle convenient being suitable for than general ecg analysis population data owing to adopted Single-chip Controlling unit to handle ecg information.

Narrate embodiment of the present utility model in conjunction with the accompanying drawings.

Fig. 1 operation principle block diagram of the present utility model;

Fig. 2 operation principle circuit diagram of the present utility model.

During enforcement, single-chip microcomputer U ₁Be circumscribed with flash memory U ₄, the composition data carrier circuit.Narrate the circuit of Fig. 2 and the main corresponding relation of Fig. 1 below.Amplifier U ₁₃(selecting AD620 for use) is as signal amplification circuit, analog-digital converter U ₉(selecting ADC1210 for use) is connected to latch U ₁₁, U ₁₂(selecting 74L5244 for use) constitutes analog to digital conversion circuit.Single-chip microcomputer U ₁(selecting 8031 for use) is connected to latch U ₃(selecting 74LS373 for use), program storage U ₂(selecting 27256 for use) constitutes Single-chip Controlling unit circuit.Interface circuit is U ₈(selecting the MAX232 interface for use).During work, electrocardiograph P ₅Signal through amplifier U ₁₃Amplify after pin 18,19 is input to analog-digital converter U ₉In, analog-digital converter U ₉Analogue signal is converted into the accessible digital signal of single-chip microcomputer exports single-chip microcomputer U to through data/address bus ₁, the signal output part pin 10,11 of single-chip microcomputer is through interface circuit U ₈Signal is exported to computer P ₄Carry out the analyzing and processing of ecg information.Single-chip microcomputer U ₁External display P ₁At any time the data message of display process owing to adopted flash memory, has therefore thoroughly been avoided conventional static state, dynamic ram additional data holding circuit, thereby has greatly been reduced system power dissipation, has increased the reliability of system.
