Description

Monitoring device for tele-determining heart sounds

This utility model belongs to medical monitoring equipment, is used for the remote remote measurement simultaneously of many people and understands patient's hear sounds.

At present doctor's hear sounds monitor device that patient uses always of seeing and treating patients mostly is stethoscope, and it can only single direct auscultation.Though someone proposes the hear sounds custodial care facility of too much people's auscultation, do not realize the function of remote measurement understanding hear sounds yet.In order to overcome above-mentioned the deficiencies in the prior art, special proposition design of the present utility model.

The purpose of this utility model just is to provide a kind of and inserts hearer's auditory meatus, do not need just can make many people remote measurement simultaneously understand its hear sounds at one's side the patient again without ear piece, makes the consultation of doctors that supplies of hear sounds openingization, the hear sounds remote measurement monitor device of teaching usefulness.

Task of the present utility model is finished in the following way, principle and Principles of Acoustics according to existing frequency-modulated transmitter, by propagating acoustical signal joint (hereinafter to be referred as Signal connector), the can (chest piece) of an a kind of frequency modulation wireless microphone and a band sebific duct is coupled together dexterously, constitute this device.This Signal connector system adopts nonmetallic materials, makes as silica gel tube, rubber tube, plastics etc., because these materials do not produce capacity effect.Because the same function that conduction sound is arranged and strengthen the sound of Signal connector with common stethoscope, this audio signal is just received by the mike in the Tuoweigong in the Signal connector like this, by being attached thereto the frequency-modulated transmitter that connects, its amplification is converted into high frequency electrical signal more then, launches through antenna.The hearer can be with common FM receiver in remote acceptance.Thereby realize understanding the purpose of its hear sounds away from patient's remote measurement.Key technology of the present utility model be the connection of relevant parts such as Tuoweigong and mike in the Signal connector and sealing and with the syndeton design of circuit board.

Below with reference to drawings and Examples this utility model is described in further detail.

Fig. 1 is the circuit and the Signal connector structural representation of this hear sounds remote measurement monitor device;

Fig. 2 is the planar structure sketch map of Signal connector;

Fig. 3 is a hear sounds remote measurement monitor device assembling back plane sketch map;

Wherein 1 is hear sounds can (chest piece), and 2 is transaudient rubber tube, and 3 is Signal connector, and 4 is the coupling of Signal connector, and 5 is nipple, and 6 are fixing mounting, and 7 is mouthpiece, and 8 is Tuoweigong, and 9 is mike.

With reference to Fig. 1, hear sounds receives by can (chest piece) 1, send into Signal connector 3 through transaudient rubber tube 2, this audio signal (hear sounds) is sent into the audio frequency amplifier of forming by BG1, C1, R1, R2 and R3 by mike then signal is amplified 20～50dB, deliver to the RF agitator of being made up of BG2, C4, L, C5, R5 through C2 again, this signal is launched through antenna at last.

With reference to Fig. 2, the coupling 4 of Signal connector is to adopt duroplasts to make, and the transaudient rubber tube of its left end and can joins, and can load and unload at any time, and the right-hand member outside is connected with the nut of screw fashion with nipple 5, and its inner chamber is absolute slick tube chamber sound channel.The inner chamber of nipple is horn-like, and the narrowest internal diameter is identical with the coupling internal diameter, and interior oral area internal diameter can be between 0.4～2.0 centimetre, and external diameter can be between 0.6～2.2 centimetre.This nipple left end is by fixedly mounting 6 and casing are fixed.The 7th, mouthpiece adopts flexible plastic tube or silica gel tube to make, and total length can be in 2～20 cm range, and internal diameter is in 0.6～2.2 cm range, and tube wall is 0.5 millimeter.This and nipple 5 that fixes and Tuoweigong 8 sockets, tube wall is smooth can be dismantled at any time.Tuoweigong 8 adopts duroplasts or silica gel to make, left side interface portion external diameter can be at 0.6～2.2 centimetre, right side bottom centre adorns a mike 9, microphonic outfan is welded with circuit board input location by two two insulated hole (two insulated hole should be identical with the lead-foot-line diameter, and good seal) that 0.6 centimetre lead-foot-line passes the Tuoweigong bottom that are no more than that connect with it.Tuoweigong and mike want step-by-step to be close together.More than total length after the mutual socket of each parts about 8～24 centimetres, (do not contain coupling length).

Enforcement of the present utility model can realize according to structure shown in Figure 3.Schematic diagram welding among Fig. 1 is pressed in the circuit assembling.Transaudient Signal connector is by shown in Figure 2, and after all parts were got all the ready, mike has been debugged peace, and to go into bottom, Tuoweigong right side fixing, settles then and fixing nipple, at last mouthpiece and above-mentioned two-piece-dress connect.The circuit of frequency-modulated transmitter is fixed after can giving debugging earlier again.Thereby finish the assembly working of this device.Receiving unit can adopt common FM receiver to realize.The interior oral area internal diameter of nipple is 1.0 centimetres in the present embodiment, and external diameter is 1.2 centimetres, and the mouthpiece total length is 5 centimetres, and internal diameter is 1.2 centimetres, and tube wall is 0.5 millimeter, and Tuoweigong left side interface portion external diameter is 1.2 centimetres.Hear sounds remote measurement monitor device best results with this ratio assembling.

Operation principle of the present utility model is such, because when human heart shrinks diastole, the opening of valve with close, the conduct vibrations that produces is to body surface, after hear sounds can (chest piece) receives the sound wave of this hear sounds, just reach transaudient Signal connector by rubber tube, be input to the frequency-modulated transmitter circuit through mike then, be transmitted into the space by antenna through amplifying the back.The hearer can receive this cardiechema signals with common FM receiver in control room a long way off, thereby reaches the effect of many people auscultation.

The utility model has the advantages that: device structure is simple, and is easy to operate, safe and reliable, portable, cheap, is applicable to the hospital of different brackets, the doctor of the different levels use of guarding, hold a consultation, pay a home visit. The doctor does not need just can realize by the stethoscope direct auscultation sonagraphy of multiple location, many internal organs, and the acoustic phase of sound effect and directly single tin of clinic perception together. It is the ideal device of current hear sounds monitoring.
