Description
Technical field:
A kind of instrument for measuring blood pressure of the present invention is specifically related to a kind of high-precision electronic instrument for measuring blood pressure.
Background technology:
Blood pressure is one of physiological parameter of wanting of body weight for humans, and it is accurately measured, and helps early discovery and differentiates the hypertension type, proposes the proper treatment suggestion.At present, the method that mainly adopts noinvasive to detect to common patient clinically, it roughly is divided into two types of artificial Ke Shi sound method and oscillographic methods; Though artificial Ke Shi sound method is more accurate; But operating difficulties, it is bigger influenced by subjective factors, though and traditional oscillographic method is simple to operate; But stability and individual adaptability are all poor, are unfavorable for its popularizing and promoting in clinical practice.
Summary of the invention:
The purpose of this invention is to provide a kind of high-precision electronic instrument for measuring blood pressure, its hardware integrated level is high, and design realizes easy; Software design has been gathered multiple advanced algorithms such as shape filtering, and degree of accuracy is high, strong interference immunity; Have excellent precision, can satisfy the general requirement of blood pressure measurement.
In order to solve existing problem in the background technology, the present invention adopts following technical scheme: it comprises power supply 1, pick off 2, cuff 3,4,16 ∑s of galvanostat-Δ type A/D converter 5, air pump 6, keyboard demonstration 7 and air valve 8; Power supply 1 is connected with pick off 2; Pick off 2 is connected to 16 ∑s-Δ type A/D converter 5, and cuff 3 is connected to pick off 2, and air pump 6 is connected to galvanostat 4; Keyboard shows that 7 connections interconnect with 16 ∑-Δ type A/D converters 5, and air valve 8 is connected with 16 ∑s-Δ type A/D converter 5.
The present invention has following beneficial effect: the hardware integrated level is high, and design realizes easy, and software design has been gathered multiple advanced algorithms such as shape filtering, and degree of accuracy is high, and strong interference immunity has excellent precision, can satisfy the general requirement of blood pressure measurement.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
The specific embodiment:
Referring to Fig. 1, this specific embodiment adopts following technical scheme: it comprises power supply 1, pick off 2, cuff 3,4,16 ∑s of galvanostat-Δ type A/D converter 5, air pump 6, keyboard demonstration 7 and air valve 8; Power supply 1 is connected with pick off 2; Pick off 2 is connected to 16 ∑s-Δ type A/D converter 5, and cuff 3 is connected to pick off 2, and air pump 6 is connected to galvanostat 4; Keyboard shows that 7 connections interconnect with 16 ∑-Δ type A/D converters 5, and air valve 8 is connected with 16 ∑s-Δ type A/D converter 5.
This specific embodiment adopts oscillographic method to carry out blood pressure and detects, and main process is to obtain the pressure signal that changes in the cuff, analyzes therefrom isolated pulse signal, finds the corresponding position of systolic pressure and diastolic pressure, thereby obtains their size.
This specific embodiment hardware integrated level is high, and design realizes easy, and software design has been gathered multiple advanced algorithms such as shape filtering, and degree of accuracy is high, and strong interference immunity has excellent precision, can satisfy the general requirement of blood pressure measurement.
