Abstract

The utility model relates to an auscultation head. The auscultation head includes a diaphragm, a sound collecting cover, a sealing sheet and a connector. The diaphragm is set on one side of the sound collecting cover and is fixedly connected by a sealing sheet. The other side of the sound collection cover is set. The sound collection cover is provided with a sound transmission channel. The sensitivity of the sound pickup and the intensity of the sound through the design of the diaphragm improve the clarity and sensitivity of the sound transmission. The inner diaphragm of the auscultation head The vibration makes the gas in the auscultation head vibrate, and the vibration is more obvious and uniform through the sound transmission channel, and then transmitted to the sound transmission rubber tube, so that the sound transmission is clearer and more sensitive when used in a doctor.

Description

a stethoscope head

技术领域technical field

本实用新型涉及一种听诊头，是听诊器上的重要组成部件，属于医疗器械领域。The utility model relates to a stethoscope head, which is an important component of a stethoscope and belongs to the field of medical instruments.

背景技术Background technique

听诊器类型目前有单用听诊器、双用听诊器、三用听诊器、立式听诊器、多用听诊器以及最新出现的电子听诊器目前，不管是哪种听诊器，都是通过拾音部分、传导部分和听音部分来进行工作，其中决定听诊器好坏的为拾音部分，也是我们俗称的听诊头。The types of stethoscopes currently include single-purpose stethoscopes, dual-purpose stethoscopes, three-purpose stethoscopes, vertical stethoscopes, multi-purpose stethoscopes and the latest electronic stethoscopes. Work, which determines whether the stethoscope is good or not is the sound pickup part, which is also commonly known as the stethoscope head.

一般来说，听诊头越大越重拾音效果越好，但是由于人体的构造，人体表面有弧度，若胸件过大，听头不能完全与人体接触，音响不仅不能很好地拾取，还会从空隙泻漏出去，因此，听诊头的大小应基于临床需要，因此听诊头有着一定的大小规定，听诊头的直径几乎都统一在45-50毫米之间，特殊的如儿科胸件的直径一般为30毫米，新生儿为18毫米，为了能够更好的拾音，需要改进听诊头的结构，使其的震膜能更好的拾音。Generally speaking, the larger and heavier the auscultation head, the better the sound pickup effect. However, due to the structure of the human body, the surface of the human body has radians. If the chest piece is too large, the head piece cannot fully contact the human body. Leakage from the gap, therefore, the size of the auscultation head should be based on clinical needs, so there are certain size regulations for the auscultation head, and the diameter of the auscultation head is almost uniform between 45-50 mm, such as the diameter of the pediatric chest piece. It is 30 mm for newborns and 18 mm for newborns. In order to pick up sound better, it is necessary to improve the structure of the auscultation head so that its diaphragm can pick up sound better.

实用新型内容Utility model content

本实用新型所要解决的技术问题是提供一种传音清晰、灵敏度高并且使医生能够准确的判断患者病情的一种听诊头。The technical problem to be solved by the utility model is to provide an auscultation head with clear sound transmission, high sensitivity and enabling doctors to accurately judge the patient's condition.

为解决上述问题，本实用新型采用以下技术方案：In order to solve the above problems, the utility model adopts the following technical solutions:

一种听诊头，其特征在于：所述听诊头包括震膜、集音罩、密封片和连接头，所述震膜套装在集音罩的一侧，用密封片固定连接，所述连接头设置集音罩的另一侧，所述集音罩上设有传声通道。A kind of auscultation head, it is characterized in that: described auscultation head comprises diaphragm, sound collecting cover, sealing sheet and connector, described diaphragm is sleeved on one side of sound collecting cover, is fixedly connected with sealing sheet, and described connecting head The other side of the sound-collecting cover is provided, and a sound transmission channel is arranged on the sound-collecting cover.

以下是对上述方案的进一步改进：The following is a further improvement on the above scheme:

所述传声通道设置在集音罩的中心位置。The sound transmission channel is arranged at the center of the sound collecting cover.

所述集音罩截面为C形，所述震膜套装在C形的集音罩开口的一侧。The section of the sound collecting cover is C-shaped, and the diaphragm is set on one side of the opening of the C-shaped sound collecting cover.

所述密封片是由截面为U形的连续的闭合环构成。The sealing sheet is composed of a continuous closed ring with a U-shaped cross section.

所述连接头上设有连接口。The connecting head is provided with a connecting port.

本实用新型与现有技术相比，具有以下特点：通过震膜的设计拾音的灵敏度和声音的强度，提高了传音清晰度和灵敏度，听诊头内震膜的震动使得听诊头中气体产生振动，通过传声通道使得震动更加明显、统一，然后传输到传声胶管中，使得在就诊使用时，传音更加清晰、灵敏度更高。Compared with the prior art, the utility model has the following characteristics: through the design of the diaphragm to pick up the sensitivity and the strength of the sound, the clarity and sensitivity of the sound transmission are improved, and the vibration of the diaphragm in the auscultation head makes the gas in the auscultation head generate The vibration, through the sound transmission channel, makes the vibration more obvious and uniform, and then transmits it to the sound transmission rubber tube, making the sound transmission clearer and more sensitive when used in medical treatment.

下面结合附图和实施例对本实用新型作进一步说明：Below in conjunction with accompanying drawing and embodiment the utility model is further described:
