Abstract

A human cardiac sounds feedback instrument is composed of cardiac sound pick-up, signal amplifier and cardiac sound feedback unit. Said cardiac sound pick-up has a disk-type casing into which an acousto-electric converter is embedded, which is connected via line to input of signal amplifier. An electro-acoustic converter is inlaid in acting head which is fixed to the lower part of handheld body to form a cardiac sound feedback unit. The input of electro-acoustic converter is connected to output of signal amplifier. Its frequency and oscillation amplitude are automatically changed with different users for high physiotherapeutic effect. Its advantage are high safety, no by-effect and low cost.

Description

Feedback apparatus for human heart sounds

Feedback apparatus for human heart sounds belongs to the human body physical therapy instrument.

No matter existing is therapeutic instrument, or physiotherapy table, and the frequency of its signal and amplitude all derive from human external, is artificial the setting, can not change automatically because of the difference of user, so the effect of its treatment and physical therapy is all undesirable.The ZL95204585 utility model patent that I have has realized using the hear sounds by therapist to make signal source, feedback and carry out the purpose that Heal Thyself keeps healthy to me, but there is deficiency that use is more numerous, inconvenient, cost is high in this patent.

The objective of the invention is to design a kind of physiotherapy table, the signal of this physiotherapy table derives from the hear sounds that uses this instrument, and have simple to operation, the characteristics that the cost of instrument own is low.

The present invention is made up of hear sounds pick-up head, signal amplification circuit, hear sounds feedback device.The hear sounds pick-up head is made up of a sucked type housing, acoustical-electrical transducer, and acoustical-electrical transducer is set in the sucked type housing, and acoustical-electrical transducer is linked to each other by the input of lead and signal amplification circuit.The hear sounds feedback device is made up of hand-held body, action head, electroacoustic transducer, the input of electroacoustic transducer is linked to each other with the signal amplification circuit outfan by lead, electroacoustic transducer is set in the action head, and the bottom of action head adopts elastomeric material to make, and the top of action head is fixed on hand-held body bottom.

Hear sounds of the present invention picks up head-shield and inhales on cave in the void of human body, after the people lies on the back, and the adept body of holding of hands, the action head of hear sounds feedback device overlays on the SHENQUE acupoint of human body.Because of signal is taken from the hear sounds of human body, this cardiechema signals is converted to behind the signal of telecommunication again through amplifying, convert sound again to and act on action head, action head makes it form a circulation with mechanical action and by being feedback to self by the frequency of treatment human body hear sounds.Use this back coupling instrument can regulate the nervous system of human body, blood circulation, hormonal system etc., can eliminate physiological barrier, make partes corporis humani's system coordination unanimity, have the effect of self regulation health therapy.Because the amplifying circuit power supply is a few V DC voltages, and back coupling action head stroke is minimum, only several mm, so it is safe and reliable to be somebody's turn to do the back coupling instrument, without any side effects and infringement, especially its signal frequency and amplitude are different and change automatically with user, so physical therapy, therapeutic effect are splendid.Compare with the ZL95204585 utility model patent, also have simple to operationly, can adjust the size of feedback signal active force at any time, so effect is better.And this instrument cost is compared than ZL95204585 utility model and has been reduced by 40%.

Fig. 1 is an overall structure sketch map of the present invention, and Fig. 2 is the shell structure sketch map that embodiment adopts.

Embodiment: present embodiment is made up of hear sounds pick-up head, signal amplification circuit 1, hear sounds feedback device, housing 2.The hear sounds pick-up head is made up of a sucked type housing 3, acoustical-electrical transducer 4.Acoustical-electrical transducer 4 is set in the sucked type housing 3, and acoustical-electrical transducer 4 is linked to each other by the input of lead 10 with signal amplification circuit 1.Signal amplification circuit 1 adopts the General Audio amplifying circuit, so need not provide its concrete circuit structure diagram.The hear sounds feedback device is made up of hand-held body 5, action head 6, electroacoustic transducer 7, the input of electroacoustic transducer 7 is linked to each other by the outfan of lead 8 with signal amplification circuit 1, electroacoustic transducer 7 is set in the action head 6, the elastic rubber material making has been adopted in 9 of action head 6 contact human body bottoms, and the top of action head 6 is fixed on the bottom of hand-held body 5.Signal amplification circuit 1 is fixed in the hand-held body 5.For ease of carrying and depositing, increase by a housing 2 again, action head 6 and reserve battery all are placed in the housing 2, hand-held body 5 constitutes the box body of a sealing as the lid of housing 2 with it.
