Abstract
The invention discloses a portable heart sound collecting device, comprising a measuring electrode, a shielding driving device, a prepositioned amplifying device, a band-pass filtering device, a high-speed sampling device and a single chip microcomputer which are connected in sequence, wherein the single chip microcomputer is further connected with a printer, a storing device and a liquid crystal display screen. A working method of the device comprises the steps that the measuring electrode collects an electric signal of a heart; a collected heart sound signal is amplified through the shielding driving device entering the prepositioned amplifying device; then, filtering is realized in the band-pass filtering device; the heart sound signal is subjected to A/D (Analogue/Digital) conversion; a converted digital signal is delivered into the single chip microcomputer to be processed; sound heart data is delivered into the liquid crystal display screen to be displayed and the sound heart data is stored, printed and output, so that a heart sound signal collection process can be finished; and the portable heart sound collecting device has the beneficial effects of convenience for carrying and no need of using too many lines.
Description
Technical field
The present invention relates to a kind of portable heart sound acquisition device and method.
Background technology
At present, heart sound acquisition device both domestic and external generally all adopts electrocardiograph, the defective that this electrocardiograph exists be bulky, price is high, need the medical personnel of specialty to use, but also needs monitoring for a long time, has brought inconvenience for the hear sounds diagnosis of some infirmaries.
It is exactly a large amount of wiring of needs that also there is a defective in traditional heart sound acquisition device, does not have just smooth signal transmission of these lines, has caused the difficulty of installing and the inconvenience of carrying.
Summary of the invention
Purpose of the present invention is exactly in order to address the above problem, and a kind of portable heart sound acquisition device and method are provided, and it has the advantage that is convenient for carrying.
To achieve these goals, the present invention adopts following technical scheme:
A kind of portable heart sound acquisition device comprises the measurement electrode, shield guard device, adapting amplifier device, band pass filter means, the high-speed sampling device that connect successively, and single-chip microcomputer, described single-chip microcomputer also are connected with printer, memorizer, LCDs.
The method of work of said apparatus is: on the electrical signal collection of described measurement electrode with heart, entering adapting amplifier device by the shield guard device amplifies the cardiechema signals that collects, in band pass filter means, realize afterwards filtering, then cardiechema signals is carried out the A/D conversion, then the digital signal after will changing is sent in the single-chip microcomputer and is processed, heart sound data is sent into the LCDs demonstration afterwards, and with heart sound data storage and printout, thereby finish the gatherer process of cardiechema signals.
Beneficial effect of the present invention:
This heart sound acquisition device has the advantage that is convenient for carrying, and makes things convenient for the domestic consumer to use, and does not use too many circuit.
Description of drawings
Fig. 1 is portable heart sound acquisition device of the present invention;
Wherein, 1, measurement electrode, 2, the shield guard device, 3, adapting amplifier device, 4, band pass filter means, 5, the high-speed sampling device, 6, single-chip microcomputer, 7, printer, 8, LCDs, 9, memorizer.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing and embodiment.
As shown in Figure 1, a kind of portable heart sound acquisition device, comprise the measurement electrode 1, shield guard device 2, adapting amplifier device 3, band pass filter means 4, the high-speed sampling device 5 that connect successively, single-chip microcomputer 6, described single-chip microcomputer 6 also are connected with printer 7, memorizer 9, LCDs 8.
The method of work of said apparatus is: on the electrical signal collection of described measurement electrode 1 with heart, entering adapting amplifier device 3 by shield guard device 2 amplifies the cardiechema signals that collects, in band pass filter means 4, realize filtering afterwards, then cardiechema signals is carried out the A/D conversion, then the digital signal after will changing is sent in the single-chip microcomputer 6 and is processed, heart sound data is sent into LCDs 8 demonstrations afterwards, and with heart sound data storage and printout, thereby finish the gatherer process of cardiechema signals.
Although above-mentionedly by reference to the accompanying drawings the specific embodiment of the present invention is described; but be not limiting the scope of the invention; one of ordinary skill in the art should be understood that; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection scope of the present invention.
