Abstract

The invention discloses a bluetooth electronic cardiophone which is characterized by comprising a portable terminal and a PC. In the portable terminal, after a sensor conducts primary amplifying, lowpass filtering and secondary amplifying on an acquired cardiac sound signal, a power amplification module conducts real-time cardiac sound playing on one path of the cardiac sound signal, and after a master control module conducts A/D conversion on the other path of the cardiac sound signal, a liquid crystal screen displays a phonocardiogram at the real time, and the other path of the cardiac sound signal is transmitted to the PC by a serial port or a bluetooth transmission module; and the PC displays the phonocardiogram at the real time through a PC screen after received cardiac data is processed by the master control module at the PC end, or the received cardiac data is stored by a storage module and assists a diagnosis module to carry out computer assisted diagnosis according to requires. Compared with the prior art, the invention has the advantages of storing and analyzing the cardiac sound data, displaying the phonocardiogram at the real time, providing more intuitive diagnosis data and giving prompts to common heart diseases, such as tachycardia, bradycardia, arrhythmia, and the like.

Description

technical field [0001] The invention relates to the technical field of computer diagnosis and medical treatment, in particular to a bluetooth electronic heart sound stethoscope. Background technique [0002] Doctors usually use a traditional mechanical stethoscope when seeing a patient. The mechanical stethoscope is composed of a listening head, a rubber tube, a metal frame, and earplugs. The heart sound is vibrated through the diaphragm of the listening head, and the heart sound is transmitted to the earplugs by the connected rubber tube. , due to structural limitations, the traditional stethoscope can only be used by one person, and the transmission distance is greatly limited. [0003] Now some electronic stethoscopes have also been developed, which have made some progress on the basis of traditional stethoscopes. The heart sound signal can be amplified and processed through the stethoscope head. (Patent No. 02144276.2) and "Medical Electronic Stethoscope" (Patent No. 20...
