Embodiment 1

[0039] Example 1, Figure 1-3 It is a structural schematic diagram of a composite stethoscope diaphragm assembly provided in Embodiment 1 of the present invention.

[0040] A composite stethoscope diaphragm assembly includes an encapsulating body part 1 and a diaphragm 4 .

[0041] Diaphragm 4 is a circular diaphragm, which is a glass fiber resin sheet with a diameter of 37.5mm. Usually, when the stethoscope sound collecting cavity is matched with a circular diaphragm, the diameter of the circular diaphragm has a fixed optimal range to ensure a good listening effect. The diameter of the circular diaphragm is 37.5mm, which is based on the above-mentioned optimal range. Find the range.

[0042] The circular diaphragm is provided with at least one vent hole, and the vent hole is located at the center and near the center of the circular diaphragm. The vent hole can avoid the circular diaphragm caused by the pressure change inside the stethoscope during the pressing process. The...

Embodiment 2

[0048] Example 2, Figure 4-5 It is a structural schematic diagram of a composite stethoscope diaphragm assembly provided in Embodiment 2 of the present invention.

[0049] A composite stethoscope diaphragm assembly includes an encapsulating body part 1 and a diaphragm 4, the diaphragm 4 is a circular diaphragm, a glass fiber resin sheet with a diameter of 37.5 mm.

[0050]The encapsulating body part 1 comprises a first annular platform 2 and a second annular platform 3 . Wherein, the diameter of the first endless belt platform 2 is less than the diameter of the second endless belt platform 3, the first annular side wall 5 is set between the first endless belt platform 2 and the second endless belt platform 3, and the second endless belt platform A second annular side wall 6 is provided at the edge of the platform 3 , and the second annular side wall 6 extends away from the first annular platform 2 . Wherein, the first end of the first annular side wall 5 is connected with t...

Abstract

The invention relates to a medical instrument accessory, in particular to a stethoscope accessory, and particularly relates to a combined-type stethoscope membrane assembly. The combined-type stethoscope membrane assembly comprises a colloid-wrapped part and membrane, wherein the colloid-wrapped part comprises a first ring belt platform and a second ring belt platform. The diameter of the first ring belt platform is smaller than that of the second ring belt platform, a first annular lateral wall is arranged between the first ring belt platform and the second ring belt platform, a second annular lateral wall is arranged at the rim of the second ring belt platform and extends towards the direction away from the first ring belt platform, and the membrane is attached to the end surface outside the first ring belt platform. The stethoscope accessory is strong in anti-audio-frequency-damping ability and durability, reasonable in effective contact area, and capable of accurately acquiring moving information of internal organs of the body and ensuring that a user makes correct diagnosis decisions.

Description

technical field [0001] The invention relates to the field of medical device accessories, and more specifically, to a composite stethoscope diaphragm assembly. Background technique [0002] The stethoscope is an important medical device for doctors to auscultate the sound changes of organs such as the human heart, lungs and pulse, and to diagnose diseases. The stethoscope mainly includes a listening head body, a rotating shaft, a rubber hose, an earhook and a diaphragm. The sound collecting effect of the sound collecting cavity formed between the listening head body and the diaphragm has an important influence on the sound amplification function of the stethoscope, so the diaphragm plays a key role in the sound transmission process. [0003] When the stethoscope collects organ audio, the diaphragm changes the wavelength of the sound waves emitted by the organ, making the changed audio frequency easily recognizable by the human ear. Therefore, the effective contact area betwe...
