Problems solved by technology

This one-piece stethoscope tube needs to use a mold during the solid-heating integral molding process during production. If the inner diameters of the upper and lower ends of the mold are made the same and the length of the hose is too long, the quality of the produced product will definitely be affected. And the use effect is not good; if the upper end and lower end of the mold and the size of the inner core are inconsistent, and the overall length is too long, it will lead to a substantial increase in the cost of manufacturing the mold and poor production stability, lower yield, and lower economic benefits

Embodiment 1

[0061] Such as image 3 and Figure 4 As shown, it is a sound guiding tube provided by this embodiment, including a three-way sound guiding section 1 and a straight tube sound guiding section 2, the interface end of the three-way sound guiding section 1 and the straight tube sound guiding section The interface ends of segment 2 are bonded together by hot-melt. The inner diameter of the sound guide section 1 of the three-way pipe is larger than the inner diameter of the sound guide section 2 of the straight pipe, and the interface between the sound guide section 1 of the three-way pipe and the sound guide section 2 of the straight pipe forms a joint mark 3 whose inner wall section is inclined. Both the sound guide section 1 of the tee pipe and the sound guide section 2 of the straight pipe are made of silica gel.

[0062] Among them, the inner diameter of the sound guide section of the three-way pipe ranges from 3mm to 6.5mm, the length ranges from 120mm to 320mm, and the pip...

Embodiment 2

[0078] The structure of the sound guide tube in this embodiment is basically the same as in Embodiment 1, as Figure 9 and Figure 10 As shown, it includes a three-way pipe sound guide section 1 and a straight pipe sound guide section 2, and the interface end of the three-way pipe sound guide section 1 and the interface end of the straight pipe sound guide section 2 are bonded on the Together. The inner diameter of the sound guide section 1 of the three-way pipe is larger than the inner diameter of the sound guide section 2 of the straight pipe, and the interface between the sound guide section 1 of the three-way pipe and the sound guide section 2 of the straight pipe forms a joint mark 3 whose inner wall section is inclined. The difference is that in this embodiment, the sound guide tube is supplemented with injection of the sound guide tube raw material or adhesive at the interface of the three-way pipe sound guide section 1 and the straight pipe sound guide section 2, so t...

Abstract

The invention discloses a leading tone tube which aims at solving the problems that an existing leading tone tube is uneven in tube wall thickness, complex in processing technology and the like. The leading tone tube comprises a T-branch tube leading tone section and a straight tube leading tone section. The connector end of the T-branch tube leading tone section and the connector end of the straight tube leading tone section are adhered together in a hot melting mode, and a connecting mark is formed at the joint. The invention further provides a manufacturing method for the leading tone tube and a mould. The leading tone tube manufactured through the manufacturing method has the advantages of being soft, low in temperature change rate, even in tube wall thickness, good in sound amplification effect, good in auscultation effect and the like. The T-branch tube leading tone section and the straight tube leading tone section are formed separately and then adhered together, so the requirements for the forming mould are low. Meanwhile, product quality and overall production efficiency are improved, and economic benefits are better.

Description

technical field [0001] The invention belongs to the field of medical device accessories, and in particular relates to a sound guide tube, a preparation method of the sound guide tube and a mold. Background technique [0002] Such as figure 1 As shown, the existing stethoscope usually adopts a whole sound guide tube, and the existing stethoscope sound guide tube is integrally molded by dipping PVC, which results in uneven wall thickness of the sound guide tube. [0003] The processing technology of the PVC sound guide tube is as follows: first assemble the disassembled mold, then heat the assembled mold, then immerse the heated mold in the PVC material, and put it into the oven for high temperature curing after the mold absorbs the PVC and forms it. , and then demould and decompose the cured and formed PVC sound guide tube, and finally cut the formed PVC tube. It can be seen that in the production process of the PVC sound guide tube, the heated mold is immersed in the PVC m...
