Dual-diaphragm drum type stethoscope capable of amplifying sound and protecting ears

Abstract

The invention discloses a dual-diaphragm drum type stethoscope capable of amplifying sound and protecting ears. The dual-diaphragm drum type stethoscope capable of amplifying sound and protecting earscomprises sound guiding ear pieces, sound guiding earrings, a curved pulling force spring piece, a Y-shaped sound guiding hose, a stethoscope head and a stethoscope head sound guiding interface. Thedual-diaphragm drum type stethoscope capable of amplifying sound and protecting ears has the structural characteristics that the sound guiding ear pieces are urn-shaped otic vesicie hoods made of flexible materials; and the stethoscope head is formed by a listening ring, a contact diaphragm mounted on a contact opening of the listening ring, and a resonant diaphragm and a resonant diaphragm fixingcover on a back opening of the listening ring. The dual-diaphragm drum type stethoscope capable of amplifying sound and protecting ears has the functional characteristics that hearing loss and pain and discomfort in external auditory meatus caused by that a doctor uses earplugs for a long time can be avoided; weak sound produced by physiological activities of human organs can be further amplified, and clear auscultation of the doctor is facilitated; and the dual-diaphragm drum type stethoscope capable of amplifying sound and protecting ears is simple and light in structure, and easy to realize. The dual-diaphragm drum type stethoscope capable of amplifying sound and protecting ears disclosed by the invention is suitable for auscultation of a clinician, and is especially suitable for integrated physical examination of organizations and groups and physical examination for fat people.

Description

Technical field [0001] The invention relates to a medical stethoscope, in particular to a double diaphragm drum type sound-raising and ear-protecting stethoscope. Background technique [0002] Stethoscope is a kind of medical diagnostic instrument with simple structure, low price, convenient carrying and wide application. It plays a vital role in clinical diagnosis and disease screening activities. However, the traditional stethoscope [such as the stethoscope product of the national high-tech enterprise "Jiangsu Fulin Medical Equipment Co., Ltd.". Address: No. 16 Xingmao Road, Zhenjiang City; Tel: 0511-85891000; Suzhen Food and Drug Administration Equipment (quan) 2013 No. 1200067; Su Food and Drug Administration Equipment Production Xu 2001-0566; YZB / Su (town) 0067 -2013] can no longer fully meet the needs of actual clinical auscultation. A brief description is as follows. [0003] 1. Subject factors [0004] (1) With the advancement of science and technology and the rapid econo...

AI Technical Summary

Problems solved by technology

In addition, due to the cushioning, shock absorption and sound insulation effect of subcutaneous fat, the vibration of the front of the hearing block that contacts the human body vibration diaphragm (hereinafter referred to as "contact body diaphragm") will be weakened, making the doctor's auscultation work strenuous

In particular, the centralized physical examination of institutions and groups will reduce the work efficiency of doctors

[0006] 2. Defects of traditional stethoscope

However, the weak sound produced by the physiological activities of human organs is difficult to make the thick metal listening block produce obvious resonance to further amplify the tiny sounds produced by the physiological activities of human organs

[0008] (2) The hearing block of the traditional stethoscope is heavy. When the stethoscope is hung on the doctor's external auditory canal for a long time, the doctor will feel pain and discomfort.

[0009] (3) The earplugs of traditional stethoscopes are spherical, mostly made of thick hard materials or semi-hard materials, and their shapes are not variable

However, for centralized physical examinations of institutions and groups, it is difficult to ensure the quietness of the physical examination environment; especially the noise interference from road construction or unit building construction as well as traffic and commercial publicity audio

Thereby this stethoscope is not very suitable for the centralized medical examination of institution group and uses

In addition, the structure of the stethoscope in this patent is relatively complicated and expensive, which will increase the cost of medical diagnosis

At the same time, there is also the problem that fault maintenance is relatively difficult, and it is not very suitable for non-educational medical structures.

[0011] 4. The defect of the stethoscope with the patent number: 201620578198.6 (authorized announcement number: CN206044650U; authorized announcement date: 2017.03.29) is that its film cover (see the first to third lines from the bottom of paragraph [0017]) should be different from that of the stethoscope. body membrane

Third, it is difficult to avoid that other parts of the auscultation head will never touch the patient's skin and the inner surface of the clothes
