Abstract

The utility model relates to a heart rate/lung sound telephone remote-control instrument, comprising a heart rate/lung sound sensor 1 an electricity supplying part 2 and an amplifier 3. The utility model is characterized in that the information about the heart rate and the lung sound of human body is picked up with the heart rate/lung sound sensor, is accessed in the speech transmitting end of a telephone circuit after the amplifying treatment and is conveyed out with a telephone line; a doctor in the distance also knows about the situation of the heart rate and the lung sound of a patient, gives the guidance and makes the suggestion.

Description

Heart rate/lungs sound phone remote sensing instrument

The utility model relates to a kind of household electronic healthy tool, is a kind of electronic installation that transmits human heart rate/lungs sound information by phone specifically.

Along with the development of society, people wish just can understand own health at home to the health care pay attention to day by day, allow not doctor at one's side also understand these basic conditions simultaneously, obtain doctor's guidance, this point needs the people of running check health particularly important to old.Existing family expenses health-care appliance such as heart rate measuring instrument only only limit to the patient and measure at home, can not directly send information to doctor, and the patient's light that lacks necessary medical expertise can't be judged own health status with these data, therefore is necessary to allow experienced doctor also understand these essential informations.

The purpose of this utility model is to provide a kind of heart rate/lungs sound phone remote sensing instrument that heart rate/lungs sound test and information transmission are combined.

For realizing the purpose of this utility model, the technical scheme that is adopted is: on known telephone set network basis, increase circuit such as heart rate/lungs sound transducer and amplifier, when the patient will have a physical examination, put through doctor's phone, according to doctor's requirement, the sensing telemetry head is placed the health corresponding site by physician guidance, the doctor just can understand essential informations such as patient's heart rate, lungs sound at the phone other end, thereby judges, and advises and requirement to the patient.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is the utility model theory diagram;

Fig. 2 is the utility model embodiment circuit theory diagrams.

The utility model is made up of heart rate/lungs sound transducer 1, power pack 2 and amplifier 3.Power pack 2 can be used dry cell for transducer 1 and amplifier 3 power supplies, also can utilize the telephone set internal electric source.Telephone set enters talking state after putting through phone, the patient places heart rate/lungs sound transducer chest, cooperates respiratory movement simultaneously by doctor's requirement, transducer 1 just is converted into the signal of telecommunication with heart rate or lungs sound, after amplifier 3 amplifications, the voice signal transmitting terminal that is linked into telephone set network sends, the doctor just can hear these signals at the phone other end, judges the basic condition of patient's cardio-pulmonary function on this basis.

The described circuit of Fig. 2 comprises a heart rate/lungs sound transducer S1, an amplifier G1 with positive input 4 and reverse input end 5, and common LM358 is exactly the integrated circuit that has comprised 2 such amplifiers on the market.Transducer S1 links to each other in due form with systematically with amplifier G1, and the two feeder ear links to each other with an end K1-1 of K switch 1, and the other end K1-2 of K1 links to each other with the positive pole of dry cell batteries EV, and battery pack EV provides 4.5V DC power supply, its negative pole with systematically link to each other.

This circuit comprises that also one is composed in series by resistance R 1 and R2, is serially connected between the K1-2 end and ground wire of switch k1, is used for providing to amplifier G1 the loop of bias voltage, and resistance R 1 links to each other with the positive input 4 of amplifier G1 with the contact of R2.

Resistance R 3 is serially connected between the output V0 and amplifier G1 reverse input end 5 of transducer S1, as input resistance in the present embodiment circuit.Resistance R 4 is attempted by between the reverse input end 6 of amplifier G1 and the output 6 as feedback resistance, and resistance R 4 and R3 ratio have determined the multiplication factor of amplifier G1.The signal of amplifier out 6 output is linked into the voice signal transmitting terminal of known telephone set network by capacitor C 1, sends by telephone wire.

The present embodiment circuit is work like this: after telephone set is got through, K1 closes a switch, circuit is connected battery pack EV supply voltage and is started working, heart rate/lungs sound transducer S1 is pressed close to chest by physician guidance, cooperate respiratory movement patient's heartbeat and lungs sound situation to transform into the signal of telecommunication by transducer S1 effect, this signal amplifies through the reverse input end 5 that resistance R 3 is input to amplifier G1, signal after amplifier G1 amplifies is input to the voice signal transmitting terminal of the machine circuit of answering the call through capacitor C 1, send out through telephone wire, thereby the doctor who makes at the phone other end hears patient's heart rate or lungs sound situation, judges and give the patient with hints and tips.The patient also can hear these sound in telephone receiver simultaneously.

The utility model is novel, and simple and direct being suitable for utilizes it can understand self health status at any time, provides a kind of desirable health check-up means to extensive patients and the elderly.
