Clinical medical multi-functional stethoscope used in department of cardiology

Abstract

The invention discloses a clinical medical multi-functional stethoscope used in the department of cardiology. The clinical medical multi-functional stethoscope comprises two earring catheters with hollow structures, wherein the tops of the opposite sides of the two earring catheters are provided with auscultation earplugs, the bottom ends of the two earring catheters are both provided with short catheters, the bottom ends of the two short catheters are both connected with a three-way tube, a bottom interface of the three-way tube is connected with a long catheter, and the other end of the longcatheter is provided with a flat auscultation head. In the clinical medical multi-functional stethoscope, the flat auscultation head is convenient to disassemble and replace, the clamping force provided by an existing stethoscope only by relying on a spring is changed through the joint cooperation of a spring and a spring piece, the clamping force needed when a doctor wears the earplugs of the stethoscope is ensured, and clamping is firmer; by adjusting the tightness of nuts, integral movement adjustment of the spring piece and a spring assembly on the two earring catheters can be achieved; by arranging a magnifying lens, the doctor conveniently and accurately observe and judge patients' conditions.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a multifunctional stethoscope for clinical medicine in the Department of Cardiology. Background technique [0002] A stethoscope is a medical instrument used to auscultate sounds in the body, such as the heart, breathing, and stomach. Auscultation with a stethoscope is an important method for doctors to examine patients and diagnose diseases. The stethoscope is mainly composed of a listening head for picking up sound, a rubber tube for conducting sound, and an earpiece for listening to sound. At present, the principle of the stethoscope is that the earpiece at the front end of the stethoscope contains a large membrane cavity, and the end of the earpiece inserted into the ear is narrow because of the narrow cavity, and the gas vibration amplitude will be larger than the cavity, which can amplify the sound wave vibration in the patient's body. This will help doctors hear sound w...

Problems solved by technology

[0003] Cardiologists usually need to use a stethoscope to listen to the patient's heart rate when examining the patient. At the same time, they need to use a timing tool; at the same time, some patients also need to observe the pupils so that the doctor can judge the patient's condition; The traditional stethoscope is relatively simple and inconvenient to use. A spring leaf is usually arranged between the two earring conduits on the existing stethoscope, but the prior art only relies on the spring leaf to provide the clamping force, and the clamping force is relatively small, and the spring leaf is used for a long time. After use, it will deform and become very loose, and it will be difficult to replace and use later, which will bring a lot of inconvenience to people. For this reason, we provide a multifunctional stethoscope for clinical medicine in the Department of Cardiology to solve the above problems
