Abstract

The utility model relates to a special component of a stethoscope. The multipurpose duplexing stethoscope sold on market adopts that two direct tubes are directly connected with two connecting handles of chest pieces from the ear stems. The two direct tubes are heavier and are easy to wind; moreover, the two direct tubes are not convenient for storing and operating. The two direct tubes are easier to rub mutually to make noises at the point of the chest pieces in the process of auscultation, which causes the noise to mix and affects the acoustic quality. The four-head dual-chamber tube of the utility model is formed in one piece through PVC liquid manufacturing process and the two heads of the dual-chamber tube are respectively provided with two small tubes. The four-head dual-chamber tube of multipurpose duplexing stethoscope has the advantages of clear sound conduction function, elimination of friction, convenient operation and portability.

Description

Multipurpose combination stethoscope four-head double lumen tube

This utility model relates to a kind of medical apparatus and instruments, is specifically related to a kind of stethoscope special-purpose member.

At present the preferable stethoscope of some external tonequality has flowed into the domestic market, the multipurpose combination stethoscope be exactly wherein use more a kind of.This stethoscope adopts two straight pipes to connect handle from upright two of connecing chest piece in succession of ear, thereby obtained preferable transaudient curve, but reflect according to user, also there are two problems in the multipurpose combination stethoscope: one is two straight pipes owing to want the engaging lug stalk, internal diameter can not be too little, consider instructions for use again and prevent that noise from scurrying into, wall thickness can not be thin excessively, so it is the pipe of 9～10cm that this straight pipe generally adopts external diameter, two straight pipes just seem comparatively heavy, the easy winding, and collection and the equal inconvenience of use; The 2nd, because these two straight pipes are independent respectively, their easy phase mutual friction produce noise at the chest piece place during auscultation, and hum is scurried into when causing auscultation, influences the acoustic quality.

The purpose of this utility model is to overcome above-mentioned shortcoming, and the four-head double lumen tube that a kind of acoustic is clear, eliminate friction, the easy to use and multipurpose combination stethoscope special use of carrying is provided.

The purpose of this utility model is achieved in that this multipurpose combination stethoscope four-head double lumen tube is the one-shot forming of PVC liquid system technology, make two tubules respectively at a double lumen tube two, two tubule engaging lug stalks of one, two of two tubules connection chest pieces of other end connect handle.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the structural representation of four-head double lumen tube of the present utility model;

Fig. 2 is an A-A cross-sectional view among Fig. 1;

Fig. 3 is the structural representation that adopts multipurpose combination stethoscope of the present utility model.

As shown in Figure 1, this four-head double lumen tube is made two tubules for the one-shot forming of PVC liquid system technology respectively at a double lumen tube two.1 is tube wall in Fig. 2, and 2 is tube chamber.Ask as Fig. 3, two tubule engaging lug stalks that this four-head double lumen tube is, two of two tubules connection chest pieces of other end connect handle.

This utility model has still kept again original two thicker straight pipes being changed into thinner one from the ear stalk preferable transaudient curve of independent UNICOM chest piece respectively, and is easy to use and carry, and friction generation noise can not take place, and the acoustic quality is good.

Claims

1, a kind of multipurpose combination stethoscope four-head double lumen tube, it is characterized in that it is the one-shot forming of PVC liquid system technology, make two tubules respectively at a double lumen tube two, two tubule engaging lug stalks of one, two of two tubules connection chest pieces of other end connect handle.
