Electronic Bluetooth stethoscope

Abstract

The invention discloses an electronic Bluetooth stethoscope. The electronic Bluetooth stethoscope comprises a sound amplification headset, a sound collection device, a microphone, a controller, Bluetooth transmission equipment and an internally-arranged power source. The microphone sends received sound signals to a microprocessor through a pre-amplification circuit, a filter circuit and a digital signal circuit in the controller for processing the signals. The microprocessor is connected with a volume adjustment switch and a Bluetooth switch. The volume adjustment switch is connected to the sound amplification headset so as to send the processed sound signals to the sound amplification headset and meet the requirement of normal auscultation. The Bluetooth switch is connected to the Bluetooth transmission equipment so as to send the collected sound signals to external terminal equipment. According to the electronic Bluetooth stethoscope, the shortcomings that an existing stethoscope is large in size and inconvenient to carry are overcome. By means of a mobile terminal popularized increasingly and matched analysis software, collection, preservation, visualization, real-time sharing, transmission and automatic analysis of the sound information of the human body surface can be achieved.

Description

Technical field [0001] The invention belongs to the technical field of medical equipment and relates to an electronic Bluetooth stethoscope. Background technique [0002] The traditional medical stethoscope uses air as a medium to transmit the faint sound from human organs into the human ear through a pipe. This kind of medical stethoscope has the following shortcomings: First, the traditional medical stethoscope is large and inconvenient to carry; secondly, the signal collected during auscultation cannot be adjusted in strength, and external sounds can also be transmitted through the tube wall to cause interference. Some patients with weak signals or hearing-impaired doctors reduce the clinical discrimination ability and bring greater trouble to clinical diagnosis. At the same time, diagnosis with the help of traditional medical stethoscopes mainly depends on the personal experience of the doctor, and audio signals cannot be performed. It is difficult to save and objectively ev...
