Auscultation mode switching automatic detection digital stethoscope and auscultation mode switching detection method

Abstract

The present invention provides an auscultation mode switching automatic detection digital stethoscope which comprises a double-deaded body member, a bell-shaped earpiece, a stethoscope sound output hole, a diaphragm capsule, and a sound sensor. The bell-shaped earpiece and the diaphragm capsule are arranged at two opposite sides of the double-deaded body member. The stethoscope sound output hole is installed in the double-deaded body member. When the stethoscope sound output hole is rotated, the sound inlet at the front end can face the bell-shaped earpiece or the diaphragm capsule. The sound sensor is at the tail end of the stethoscope sound output hole and is used for detecting auscultation sounds. The improvement of the stethoscope is that the stethoscope also comprises an auscultation mode detector installed on the outer wall of the stethoscope sound output hole, the direction of the auscultation mode detector is the same as that of the stethoscope sound output hole, the auscultation mode detector is used for detecting and identifying the auscultation mode arranged by the digital stethoscope. According to the auscultation mode switching automatic detection digital stethoscope, the automatic switching of a measuring mode can be realized, and thus the additional operation of mode switching in digital stethoscope application is eliminated.

Description

technical field [0001] The invention relates to a medical stethoscope, in particular to a digital stethoscope with automatic detection of auscultation mode switching. Background technique [0002] The stethoscope is the most commonly used diagnostic instrument for doctors of internal and external gynecology and pediatrics. It is a sign of a doctor and is widely used in the auscultation of the heart and lungs. Since the stethoscope was used clinically 200 years ago, the basic structure has not changed much, mainly including body parts, sound transmission parts and listening parts used to detect sound in contact with the human body, but the performance and use of the stethoscope have changed a lot . The original acoustic stethoscope was developed from a simple wooden single-ear earpiece; to a binaural acoustic stethoscope with a rubber tube that conducts sound; the body parts are in the form of a bell (low-frequency lung sound) and a capsule (heart high-frequency sound).

This is because the current digital stethoscopes all adopt a single bellows body structure

It is very convenient to adopt a single bellows body design to reduce the weight of the digital stethoscope and simplify the maintenance of the sensor, but the bellows body is more suitable for auscultation of the heart, so when the digital stethoscope is used for lung auscultation, the user needs to adjust the electric current. The mode button of the stethoscope, and the display of the stethoscope displays that the current signal processing mode is "lung sound mode". During use, press the body piece on the patient's auscultation site with appropriate force to achieve lung auscultation, which cannot be used for heart / lung measurement It is not very convenient to switch between
