Abstract

The utility model discloses a three-point adsorption stethophone consisting of a stethoscope head (A), a hose (B) and an ear piece (C), wherein the stethoscope head (A) is provided with a rubber ball (1), a base (2), a stethoscope head wall interspace (9) and three adsorption feet (5a,5b and 5c) which are mutually communicated. In auscultation, the rubber ball (1) is extruded by fingers, the generated negative pressure can be transmitted to the three adsorption feet (5a, 5b and 5c) to form three-point adsorption through the base (2) and the stethoscope head wall interspace (9), even for auscultation on the rugged chest of a thin and weak patient, and the stethoscope head also can be firmly adsorbed on the skin of the patient. In the auscultation process, a doctor does not need to press the stethoscope head by hand, the auscultation is easier and more convenient, fatigue and lumbago can not be caused by long-time auscultation, the additive interference sound generated by pressing the stethoscope head can be avoided, and the auscultation is more clear and accurate.

Description

3 adsorption-type stethoscopes

Affiliated technical field

This utility model relates to a kind of 3 adsorption-type stethoscopes, is a kind of medical diagnosis instrument.

Background technology

The stethoscope that present most of doctor uses all is simple common stethoscope, and doctor's auscultation head that will always press...with one's finger could invest auscultation head card on the patient skin long-time easy lumbago of auscultation Shi doctor and fatigue in the auscultation process; In addition, because doctor's heartbeat conducts to the trickle vibration of hand and the muscle of hand own and the light activity of patient body etc., can cause the doctor to point and the auscultation head between, produce the fine motion friction between auscultation head and the patient skin, thereby can produce comparatively significantly additional interference sound, the definition of appreciable impact auscultation and accuracy.

Above-mentioned in order to eliminate owing to the doctor hands the additional interference mail topic that the auscultation head produces, someone has designed " the adsorption-type stethoscope (patent No.: 92232852.8) ", this adsorption-type stethoscope is adsorbed on the auscultation head on the patient skin by absorption ring (being the ring-type sucker), but when running into comparatively thin and weak patient, especially when chest carries out the auscultation of cardiopulmonary, because the existence of rib, skin of chest is uneven, the everywhere of absorption ring can both be attached at closely on the patient skin in very difficult assurance, and any one gas leakage on the absorption ring all will cause adsorbing failure or adsorption time is too short, can not satisfy doctor's auscultation needs, thereby still exist certain defective, require further improvement.

Summary of the invention

Must hand the shortcoming of auscultation head and the deficiency that above-mentioned " adsorption-type stethoscope " regular meeting can not reliably adsorb because of gas leakage when overcoming common auscultation with stethoscope; this utility model provides a kind of adsorption heldfree type stethoscope more reliably; even carry out auscultation on the rough skin of chest of thin and weak patient surface; its auscultation head also can be adsorbed onto on patient's the skin securely, makes doctor's auscultation light, convenient, clear, accurate more.

The purpose of this utility model is achieved in that described 3 adsorption-type stethoscopes, form by auscultation head (A), flexible pipe (B) and ear piece (C), wherein, auscultation head (A) is provided with rubber bulb (1), pedestal (2), an auscultation wall cavity (9) and three the absorption feet (5a, 5b, 5c) that are interconnected.Push rubber bulb (1) with finger during auscultation, the negative pressure that produces can conduct to three through pedestal (2) and an auscultation wall cavity (9) and adsorb feet (5a, 5b, 5c), area of auscultation skin is formed bikini absorption, even carry out auscultation, also the auscultation head can be adsorbed on the patient skin securely at the rough chest of thin and weak patient.

The beneficial effects of the utility model are: the auscultation head forms bikini absorption by three absorption feet, solved the absorption ring type suction type problem of gas leakage easily, even run into comparatively thin and weak patient, also can be adsorbed onto the auscultation head on the patient skin securely, no longer need doctor's auscultation head that always press...withes one's finger in the auscultation process, light more, convenient during auscultation, even long-time auscultation can tired lumbago yet, but also can avoid the additional interference sound that produces owing to the hand-held auscultation head of doctor, thereby during auscultation more easy and convenient, safe reliable, clear accurately.

The specific embodiment

In Fig. 1, this utility model is made up of auscultation head (A), flexible pipe (B) and ear piece (C).

In Fig. 2,3,4,5, rubber bulb (1) is positioned at the back side of auscultation head, is communicated in an auscultation wall cavity (9) through pedestal (2).An auscultation wall cavity (9) is positioned between an auscultation outer wall (3) and the auscultation inwall (6).At the peripheral place of the auscultation face of auscultation head, an auscultation outer wall (3) is mutually continuous with an auscultation inwall (6).Three the absorption feet (5a, 5b, 5c) that evenly separate are attached on the outer peripheral edges of auscultation head, and all are communicated in an auscultation wall cavity (9).

During auscultation, earlier with finger extruding rubber bulb (1), the auscultation head is attached on the patient skin, unclamp finger back rubber bulb (1) voluntarily elasticity swell the formation negative pressure, this negative pressure conducts to an auscultation wall cavity (9) through pedestal (2), conduct to three absorption feet (5a, 5b, 5c) at last, area of auscultation skin is formed firm bikini absorption.

The activity of patient's internal organs conducts to area of auscultation skin, causes auscultation thin film (7) vibration, and then causes the air vibration in the collection sound chamber (8) and produce sound, spreads out of pipe (4) by sound to spread out of, through flexible pipe (B) arrival ear piece (C).

Claims

1. 3 adsorption-type stethoscopes, be made up of auscultation head (A), flexible pipe (B) and ear piece (C), it is characterized in that: auscultation head (A) is provided with rubber bulb (1), pedestal (2), an auscultation wall cavity (9) and three the absorption feet (5a, 5b, 5c) that are interconnected.

2. 3 adsorption-type stethoscopes according to claim 1 is characterized in that: three absorption foot (5a, 5b, 5c) uniform distribution on the auscultation head are attached to respectively on the outer peripheral edges of auscultation head.
