Abstract
The utility model relates to a chip microcomputer pulse gauge, which comprises a single chip microcomputer control system, an infrared sensor transmitting terminal (VD1), an infrared sensor receiving terminal (VD2), a single amplifying and waveshaping circuit and a nixie tube display; when a finger is placed between the infrared sensor transmitting terminal (VD1) and the infrared sensor receiving terminal (VD2), the infrared sensor receiving terminal (VD2) outputs pulse signals corresponding to heartbeat, the infrared sensor receiving terminal (VD2) is connected with the signal amplifying and waveshaping circuit, the pulse signals are connected with the single chip microcomputer control system after passing through the signal amplifying and waveshaping circuit, and the single chip microcomputer sends the time that pulse beats in every minute to the nixie tube display for display.
Description
Technical field
This utility model relates to a kind of single-chip microcomputer electronic sphygmograph, belongs to medical instruments field.
Background technology
Doctor and nurse feel the pulse will for the patient who is in hospital and record patient's per minute frequency of pulse every day, method is by on the tremulous pulse of patient's wrist with hands, count according to beating of pulse, in order to save time, generally can not do 1 minute measurement, normally measure the number of times of heart beating in 10 seconds, again the result be multiply by 6 beats that namely obtain per minute, even do so still more time-consumingly, and precision is not high yet.
Summary of the invention
This utility model is intended to invent a kind of electronic sphygmograph of single-chip microcomputer, for doctor and nurse save time when surveying pulse to patient, accomplishes simultaneously to measure precisely.
For realizing above-mentioned purpose, this utility model adopts following scheme:
Comprise that single-chip computer control system, infrared ray sensor transmitting terminal (VD1), infrared ray sensor connect end (VD2), signal amplification shaping circuit, charactron display, as shown in Figure 1;
Finger connects between the end (VD2) at infrared ray sensor transmitting terminal (VD1) and infrared ray sensor, the pulse signal that infrared ray sensor receiving terminal (VD2) output is corresponding with the heart beating beat, infrared ray sensor receiving terminal (VD2) is connected with the signal amplification integeral type circuit, pulse signal is through the signal amplification integeral type circuit, link to each other with single-chip computer control system, single-chip computer control system is delivered to the charactron display with the number of times of per minute beat pulse and is shown again.
Below in conjunction with accompanying drawing, work process of the present utility model is described:
Finger connects between the end (VD2) at infrared ray sensor transmitting terminal (VD1) and infrared ray sensor, the flow of blood is along with the variation of beating of heart in the blood vessel, because finger is placed in the bang path of light, the variation of blood saturation will cause that the transfer strength of light changes in the blood vessel, this variation is corresponding with the beat of heart beating, so that infrared ray sensor receiving terminal (VD2) the output pulse signal corresponding with the heart beating beat, pulse signal is through the signal amplification integeral type circuit, link to each other with single-chip computer control system again, the single-chip computer control system pulse signals is delivered to the number of times that the charactron display demonstrates the per minute beat pulse after processing.
The beneficial effects of the utility model:
As long as finger is put into infrared ray sensor transmitting terminal (VD1) and infrared ray sensor connects several seconds between the end (VD2), just can draw the number of times of per minute beat pulse, and be presented at very accurately on the charactron display, just can see very intuitively the result of measurement.
Description of drawings:
Accompanying drawing 1 is structure chart of the present utility model.
The specific embodiment:
In order to make the technical solution of the utility model clearer, below in conjunction with drawings and Examples, this utility model is further described, instantiation described herein only in order to explain this utility model, is not limited to this utility model.
Practical measuring examples 1:
(1) infrared ray sensor transmitting terminal (VD1), infrared ray sensor are connect the both sides that end (VD2) is separately fixed at plastic grip;
(2) again plastic grip is clipped on the hands root, detection through 2 seconds, the waveform of beat pulse is passed to signal amplification shaping circuit, be connected to interface microcontroller, after single-chip microcomputer is processed this, the number of times of per minute heart beating passed on the charactron display show.
Claims (1)
1. a single-chip microcomputer electronic sphygmograph comprises that single-chip computer control system, infrared ray sensor transmitting terminal (VD1), infrared ray sensor connect end (VD2), signal amplification shaping circuit, charactron display; It is characterized in that: finger connects between the end (VD2) at infrared ray sensor transmitting terminal (VD1) and infrared ray sensor, the pulse signal that infrared ray sensor receiving terminal (VD2) output is corresponding with the heart beating beat, infrared ray sensor receiving terminal (VD2) is connected with the signal amplification integeral type circuit, pulse signal is through the signal amplification integeral type circuit, link to each other with single-chip computer control system, single-chip computer control system is delivered to the charactron display with the number of times of per minute beat pulse and is shown again.
