Abstract
A kind of reflection type photoelectricity pulse measurement device disclosed in this utility model, this measuring instrument comprises photoemission module, light-sensitive device, Signal-regulated kinase, CPU and display module.The visible ray that photoemission module sends green band projects into skin, hypodermic reflective light intensity can change with pulse, after light-sensitive device detects the change of this light intensity, be translated into faint change in electric, this signal carries out amplification shaping through Signal-regulated kinase, and becoming can by the digital signal of CPU identification, and CPU is through calculating, obtain human pulse value, send into display module and show.A kind of reflection type photoelectricity of this utility model pulse measurement device has that integrated level is high, low in energy consumption, the feature of miniaturization, facilitates body-worn to use.
Description
Technical field
This utility model relates to pulse measurement device technical field, is specifically related to a kind of reflection type photoelectricity pulse measurement device.
Background technology
Along with the development of society, the living standard of people improves day by day, and healthy status in people's life is more and more important, is familiar with, prevents and finds ahead of time that disease is one of approach ensureing health.
Pulse carries the information of abundant human health status, and since threeth century of Christian era China Monographs on sphygmology Pulse Classic the earliest comes out, Sphygmology is constantly developed and improves.In the traditional Chinese medical science four diagnostic methods (hope, hear, ask, cut), pulse-taking occupies very important position.Pulse-taking is a diagnostic method most characteristic in China's traditional medicine, with a long history, abundant in content.Although pulse-taking is easy, noinvasive, painless, in long-term medical practice, also expose some defects.First, pulse-taking distinguishes pulse condition feature only according to doctor's doigte, is subject to feeling, the restriction of experience and statement, and there is many factors that gets sth into one's head unavoidably, have impact on the standardization judged pulse condition; Secondly, the skill of this finger feeling the pulse is difficult to grasp; Moreover the pulse condition of perception cannot record and preserve the research that have impact on mechanism of pules condition.The qualitatively this and subjectivity of pulse-taking, have impact on its precision and feasibility greatly, becomes pulse wave spectrum application, development and the restraining factors in exchanging.
Hospital nurse all will be felt the pulse to inpatient every day, record patient Pulse Rate per minute, method be with hands by the tremulous pulse of patient's wrist, count according to beating of pulse.In order to save time, generally can not do the measurement of 1 minute, normally measure 10 seconds beat pulse numbers, then result is multiplied by 6 namely obtains Pulse Rate per minute, this method is not only time-consuming, and precision is not high yet.As inpatient adopts pulse measurement device record Pulse Rate, above problem will be overcome.
Summary of the invention
The purpose of this utility model is to provide a kind of reflection type photoelectricity pulse measurement device, by photoemission module, light-sensitive device, Signal-regulated kinase, CPU and display module, improves pulses measure speed and precision.
For achieving the above object, a kind of reflection type photoelectricity pulse measurement device disclosed in this utility model, comprises photoemission module (1), light-sensitive device (2), Signal-regulated kinase (3), CPU (4) and display module (5).The visible ray that photoemission module (1) sends green band projects into skin, hypodermic reflective light intensity can change with pulse, after light-sensitive device (2) detects the change of this light intensity, be translated into faint change in electric, this signal carries out amplification shaping through Signal-regulated kinase (3), becomes the digital signal that can be identified by CPU (4), and CPU (4) is through calculating, obtain human pulse value, send into display module (5) and show.Photoemission module (1) uses green LED as light source.CPU (4) adopts low-power scm.Display module (5) adopts LCD or OLED.
A kind of reflection type photoelectricity pulse measurement device disclosed in this utility model has that integrated level is high, low in energy consumption, the feature of miniaturization, facilitates body-worn to use.
Accompanying drawing explanation
Fig. 1 is population structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is elaborated.
Shown in Fig. 1, a kind of reflection type photoelectricity pulse measurement device of this utility model, comprises photoemission module (1), light-sensitive device (2), Signal-regulated kinase (3), CPU (4) and display module (5).The visible ray that photoemission module (1) sends green band projects into skin, hypodermic reflective light intensity can change with pulse, after light-sensitive device (2) detects the change of this light intensity, be translated into faint change in electric, this signal carries out amplification shaping through Signal-regulated kinase (3), becomes the digital signal that can be identified by CPU (4), and CPU (4) is through calculating, obtain human pulse value, send into display module (5) and show.Photoemission module (1) uses green LED as light source.CPU (4) adopts low-power scm.Display module (5) adopts LCD or OLED.
