Abstract
The utility model relates to a pulse meter, which comprises a sensor, a signal amplifying circuit and a display circuit. The utility model is characterized in that the sensor is in a finger stall shape and is composed of a casing body, piezoelectric ceramic and a pressure regulating slide sheet; output signals of the sensor are connected to the input terminal of the signal amplifying circuit by conducting wires; signals are displayed by a digital display electronic meter. The utility model has the advantages of small volume, light weight, portability, dynamic measure, convenient use, and time saving. Besides, the utility model can be used for measuring at any time and at any place, and the postures of measured persons are not limited by the utility model. The utility model can be used as a medical detecting instrument and a teaching experiment aid and is suitable for monitoring in families with patients with middle and old aged hypertension and coronary heart diseases simultaneously.
Description
This utility model is that a kind of medical treatment detects apparatus, particularly a kind ofly measures the pulsometer that pulse is used.
Measuring now human pulse frequency and P-P or R-R interval generally is to adopt electrocardiograph.This electrocardiograph no doubt has to be measured accurately, function congruence advantage, but because of its volume is big, and testee's condition restriction such as must lie on the back can not realize fast it, anywhere or anytime measurement.
The purpose of this utility model provides a kind of portable pulsometer, and it can overcome existing shortcoming in the prior art, can carry, and realizes measuring anywhere or anytime fast, and the measured is not had the position restriction.
The purpose of this utility model is achieved in that it comprises pick off, signal amplifies and display circuit, it is characterized in that pick off is a fingerstall shape, it is by housing, piezoelectric ceramics and pressure are regulated slide plate and are formed, signal of sensor is wired to the input of signal amplification circuit, and signal shows the employing digital display electronic watch.
During measurement, only need the finger cot type sensor sleeve on finger, opening power is regulated slide plate, makes the moderate pressure of fingerstall to finger, just the fluctuating signal on the finger can be shown by numeral or sound and light display after amplifying.
The utility model has the advantages that: volume is little, in light weight, be easy to carry, so can realize measuring anywhere or anytime, the tested person there is not the position restriction, so easy to use, save time, can carry out the pulses measure of human body in advancing, this utility model detects the apparatus except that can be used as medical treatment, can also be suitable for middle and old age hypertension simultaneously as the education experiment apparatus, the monitoring of patients with coronary heart disease family is used.
Below in conjunction with embodiment and accompanying drawing thereof this utility model is done into explanation.
Fig. 1 is a general illustration of the present utility model.
Fig. 2 is that signal amplifies, the display circuit schematic diagram.
Fig. 3 is the structural representation of pick off.
3 is pick offs among the figure, pick off is made finger cot type, be piezoelectric ceramics 6 to be housed below the arc shell 5 above, one end of arc shell and piezoelectric ceramics is fixedlyed connected, the 7th, pressure is regulated slide plate, head on piezoelectric ceramics below it, be stuck in the edge of shell above, the pulse signal that pick off records is delivered to the A of amplifying circuit by lead and socket 2, B two inputs, amplifying circuit is by BG1, BG2 forms, and signal is after amplifying, deliver to numeral and sound display circuit, numeral shows employing timing digital and electronic table, and the outfan of amplifier connects a relay J, the outfan C of relay, D connects in meter circuit second of electronic watch.The outfan of amplifying circuit also is connected with the oscillating circuit of being made up of BG3, R1, R2, R3, and is connected with buzzer Y at its outfan, thereby realizes that sound shows.Foregoing circuit all is assembled in the shell 1, and 4 is digital display screens on the shell, and K1 is an on and off switch, and K2 is the open and close controlling switch of relay, and the zero circuit that returns of electronic watch inserts K3, and timing circuit inserts K4, and regulating circuit inserts K5.
