Portable intelligent stethoscope

Abstract

The invention discloses a portable intelligent stethoscope which comprises a handheld part and a stethoscope head which are assembled together, and the handheld part is provided with a display screen, a mode selection key and a power manager. An MCU microprocessor on the stethoscope head is respectively connected with a display screen, a mode selection key, a power manager, a health acquisition module, a signal acquisition module, a signal processor, a Bluetooth transmitter and an amplifier, the health acquisition module comprises a plurality of electrode plates and a collector, the electrode plates output current, the collector collects impedance, and the current and the impedance are fed back to the MCU microprocessor to establish a regression equation; the signal acquisition module acquires sound signals and transmits the sound signals to the signal processor for analog-to-digital conversion and filtering. According to the portable intelligent stethoscope, the defects that in the prior art, a stethoscope is inconvenient to store and use, tedious to operate, prone to being interfered by the surrounding environment and the like are effectively overcome.

Description

technical field [0001] The invention belongs to the technical field of medical instruments and relates to a portable intelligent stethoscope. Background technique [0002] The stethoscope is a medical instrument commonly used by doctors to collect and amplify the sounds in the human body, including heart sounds, breath sounds, bowel sounds, etc. [0003] Most of them are mechanical stethoscopes currently on the market, mainly consisting of a sound pickup part (chest piece), a conduction part (rubber tube) and a listening part (earpiece). This stethoscope has the following defects: (1) the catheter is too long and it will be inconvenient to carry, store and use; (2) it is cumbersome to operate, and it is easy to slip when hanging on the neck; (3) it is greatly disturbed by the surrounding environment, and the volume of the sound cannot be adjusted. [0004] With the development of electronic technology, various digital stethoscopes have appeared on the market, such as the "J...

AI Technical Summary

Problems solved by technology

This stethoscope has the following defects: (1) the catheter is too long, which will cause inconvenience in carrying, storage, and use; (2) the operation is cumbersome, and it is easy to slip off when hanging on the neck; (3) it is greatly disturbed by the surrounding environment, and the volume of the sound cannot be adjusted

This kind of stethoscope has the following disadvantages: (1) When the network is poor or the number of cloud visits surges, it will cause a large delay, which greatly reduces the user experience; (2) The economic cost of online auscultation is high
