Connecting tube for stethoscope and ear hook rubber tube connecting assembly

Abstract

The invention relates to a connecting structure between an ear hook and a sound guide rubber tube of a stethoscope, in particular to a connecting tube for connecting the ear hook and the sound guide rubber tube and an ear hook rubber tube connecting assembly. According to the connecting tube for the stethoscope, the connecting tube is used for connecting the ear hook with the sound guide rubber tube, and the connecting tube ensures communication between an ear hook tube cavity and a sound guide rubber tube cavity. The connecting tube is a flexible straight hollow rubber tube; the two ends of the connecting tube are arranged at the two ends of the ear hook in a sleeving mode; a hole penetrating through the single-side tube wall is formed in the middle of the connecting tube; and the hole isused for enabling the tube cavity of the connecting tube to communicate with the tube cavity of the sound guide rubber tube. The connecting tube has the advantages of being small in size, convenientto carry, low in cost, high in percent of pass, free of flashes in the tube cavity wall of the sound guide rubber tube, smooth in tube cavity sound guide and balanced and clear in listening.

Description

technical field [0001] The invention relates to a connection structure between an earhook and a sound-guiding rubber hose of a stethoscope, in particular to a connecting pipe and an earhook rubber hose connecting assembly for connecting the earhook and the sound-guiding rubber hose. Background technique [0002] In the prior art, the earhook of the stethoscope is directly connected to the sound-guiding rubber hose, and the sound-guiding rubber hose is Y-shaped or U-shaped, and the two ends of the Y-shaped or U-shaped sound-guiding rubber hose are directly socketed on the earhook (the left earhook on the left earhook hose end of the right earhook and the right earhook hose end of the right earhook). [0003] However, no matter the sound-guiding hose is prepared by dipping or injection molding, due to the special shape of the sound-guiding hose, the mold core for producing the sound-guiding hose can only be spliced ​​in splits to ensure that the mold core can be taken out of...

Problems solved by technology

[0004] Secondly, the flash on the lumen wall of the sound-guiding hose at the Y-shaped junction did not completely block one side of the lumen, but because the flash cannot be found visually in the lumen of the sound-guiding hose, it cannot be detected even with audio testing equipment. Effective detection found flashes, so the quality of the product cannot be guaranteed; when this product enters the market and is used by doctors, when listening to patients' subtle audio such as respiratory rales and heart murmurs, it often happens that they cannot hear or can't hear clearly or left and right. Consequences of Unbalanced Hearing

However, about 5% of the sound-guiding hoses in the prior art cannot detect the narrowing of the lumen sound-guiding channel when they are produced, which eventually leads to the doctor’s subtle audio frequency being unable to auscultate.

[0005] Furthermore, if two straight sound-guiding rubber hoses are used to connect with the left earhook and the right earhook respectively, on the one hand the cost of the user is increased, and on the other hand the two straight sound-guiding rubber hoses are respectively connected to the left earhook and the right earhook. After the right earhook is connected, the third sound guide hose needs to be connected. At the junction of the three sound guide hoses, a connector is needed to make the lumens of the three sound guide hoses communicate, so it is very cumbersome and unsightly. After the combination of the sound-guiding rubber hose, the volume of the sound-guiding rubber hose is too large, which is not easy to carry, causing inconvenience to the doctor's use or visits
