Low-cost multifunctional stethoscope

Abstract

The invention discloses a low-cost multifunctional stethoscope. The low-cost multifunctional stethoscope includes a stethoscope head piece, a chest piece and a heating box; the stethoscope head piece includes stethoscope earplugs and ear tubes, the ear tubes are connected with an auditory tube, the tail end of the auditory tube is provided with a control module, the control module is connected with a stethoscope metal rod, the stethoscope metal rod is connected with an MEMS microphone and a bell-shaped stethoscope head, the midpoint of the heating box is provided with a chest piece placement portion, the side face of the chest piece placement portion is provided with a temperature sensor, the lower end under the chest piece placement portion is provided with a heating module, the heating module mainly includes two parts, namely a resistance heating wire and a temperature control chip, and the resistance heating wire and the temperature control chip are connected through a copper wire. According to the low-cost multifunctional stethoscope, specific auscultation can be conducted by using bell-shaped stethoscope heads different in type according to the auscultation requirement, the heating box is used for pre-heating the chest piece, the discomfort of a user when the stethoscope makes contact with the user is reduced, functions are rich, and the production cost is relatively low.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a low-cost multifunctional stethoscope. Background technique [0002] The stethoscope is the most commonly used diagnostic tool for internal and external gynecologists and children, and is a symbol of doctors. Modern medicine began with the invention of the stethoscope. In today's society, auscultation is still an indispensable routine inspection method for clinicians. The stethoscope is an acoustic medical device commonly used in medicine. Doctors often use auscultation to evaluate the heart function and the state of the respiratory system. At present, the main clinical application of heart sound auscultation is a stethoscope with low mechanical precision. Such a stethoscope has many disadvantages in heart sound analysis: 1. The low-cost production also brings inaccurate sound collection results, 2. The lack of quantitative analysis preprocessing technology and joi...
