Abstract

The utility model provides a stethoscope with a heart rate counting function. The stethoscope with the heart rate counting function comprises two ear plugs and a stethoscope head, wherein a sound guide tube is arranged on the end part of each ear plug; a hose is arranged between each sound guide tube and the stethoscope head; a count decoding and display module and a battery are arranged on one surface of the stethoscope head; a reference time generation circuit, a control circuit, a frequency multiplier, an amplification shaping circuit and a sensor are arranged in the stethoscope head; the count decoding and display module, the battery and the reference time generation circuit are connected with the control circuit respectively; the control circuit is sequentially connected with the frequency multiplier, the amplification shaping circuit and the sensor. The stethoscope has the beneficial effects that the stethoscope has a stethoscopy function of an ordinary stethoscope and the heart rate counting function the ordinary stethoscope does not have, and is convenient to use and high in accuracy, the problems of difficulty in heart rate counting occasionally due to weak heart sounds, high heart rate and the like in a physical examination process are solved, and meanwhile, convenience is brought to the emergency work of a doctor.

Description

The stethoscope with heart rate tally function

Technical field

This utility model belongs to technical field of medical instruments, relates to a kind of stethoscope with heart rate tally function.

Background technology

Doctor for patient, have a physical examination or first aid process in, not only to use stethoscope and listen patient's hear sounds power and the rhythm of the heart neatly whether, also in the process of carrying out a medical examination, pass through timer, number goes out patient's heart rate number etc.In operating process, sometimes because hear sounds is too weak or rapid heart rate, make heart rate counting become difficult, bring puzzlement and inconvenience also can to doctor's rescue service simultaneously.

Utility model content

The purpose of this utility model is to provide a kind of stethoscope with heart rate tally function, has solved the problem of inconvenience while not having enumerator, doctor to measure heart rate to patient on the stethoscope of prior art.

The technical scheme that this utility model adopts is, has the stethoscope of heart rate tally function, comprises two earplugs and auscultation head, and two earplug ends are equipped with sound guide tube, between sound guide tube and auscultation head, are provided with flexible pipe,

The wherein one side of auscultation head is provided with count decoding display module and battery, auscultation head inside is provided with and produces circuit, control circuit, doubler, amplification and rectification circuit and sensor fiducial time, count decoding display module, battery and fiducial time produce circuit and be connected with control circuit respectively, control circuit is connected successively with doubler, amplification and rectification circuit and sensor.

Feature of the present utility model is also,

Sensor adopts TLP521-1, and amplification and rectification circuit adopts OP07 amplifier, and doubler adopts 4070BD, and control circuit adopts 555 intervalometers, and count decoding display module adopts 74ls160 and CD4511.

The beneficial effects of the utility model are, existing common stethoscopic auscultation function, the heart rate tally function that has again general stethoscope not have, and easy to use, accuracy is high, has solved in physical examination process because hear sounds is too weak or the reason such as rapid heart rate, causes heart rate to count difficult problem, bring convenience also to doctor's rescue service simultaneously, also do not take up room.

Accompanying drawing explanation

Fig. 1 is the stethoscopic structural representation that the utlity model has heart rate tally function;

Fig. 2 is the auscultation with stethoscope header structure schematic diagram that the utlity model has heart rate tally function;

Fig. 3 is the circuit theory diagrams that the utlity model has the auscultation with stethoscope head of heart rate tally function.

In figure, 1. flexible pipe, 2. sound guide tube, 3. earplug, 4. auscultation head, 5. count decoding display module, 6. battery, 7. produces circuit fiducial time, 8. amplification and rectification circuit, 9. doubler, 10. control circuit, 11. sensors.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, this utility model is elaborated.

As shown in Figure 1-Figure 3, the utility model discloses a kind of stethoscope with heart rate tally function, comprise that 4, two earplug 3 ends of two earplugs 3 and auscultation head are equipped with sound guide tube 2, between sound guide tube 2 and auscultation head 4, be provided with flexible pipe 1,

Auscultation head 4 wherein one side is provided with count decoding display module 5 and battery 6, auscultation head 4 inside are provided with and produce circuit 7, control circuit 10, doubler 9, amplification and rectification circuit 8 and sensor 11 fiducial time, count decoding display module 5, battery 6 and produce circuit 7 fiducial time and be connected with control circuit 10 respectively, control circuit 10 is connected successively with doubler 9, amplification and rectification circuit 8 and sensor 11.

Sensor 11 adopts TLP521-1, and amplification and rectification circuit 8 adopts OP07 amplifier, and doubler 9 adopts 4070BD, and control circuit 10 adopts 555 intervalometers, and count decoding display module 5 adopts 74ls160 and CD4511.

The utlity model has the stethoscope of heart rate tally function, use Shi doctor that earplug 3 is put into ear, auscultation head 4 is pressed in to patient chest, allow one of count decoding display module 5 face up, listen patient's heart beating number of times, sensor 11 is converted to corresponding electric impulse signal by beat pulse signal, through amplification and rectification circuit, 8 shapings are amplified, doubler 9 carries out frequency raising, producing circuit 7 fiducial time guarantees under controlling fiducial time, make pulse signal after 2 frequencys multiplication after control circuit 10, be sent to count decoding display module 5, through counting, decoding, can on count decoding display module 5, show, facilitate doctor to understand patient heart rate number, solved in physical examination process sometimes because of hear sounds too a little less than, or the reason such as rapid heart rate, cause counting heart rate difficult problem, bring convenience also to doctor's rescue service simultaneously, also needn't the occupying volume external space.
