The invention relates to the field of
medical instruments, in particular to an
electronic stethoscope and an electronic stethoscopy
system. The
electronic stethoscope comprises an electronic sensor, a
microcontroller unit (MCU), a
signal selection circuit, a
Bluetooth circuit, a display circuit, a storage circuit, a
signal processing circuit and a power supply
system. The
signal selection circuit selects different stethoscopy frequencies through keys, signals are acquired through the electronic sensor, the acquired signals are transmitted to the
signal processing circuit, and digital signals obtained after
processing are transmitted to the MCU. The
Bluetooth circuit, the display circuit, the storage circuit and the power supply
system are connected with the MCU, and the
Bluetooth circuit is further connected with a plurality of Bluetooth headsets, so that the multi-user stethoscopy function is achieved. The
electronic stethoscope is combined with a local PC and a remote PC, has a wide stethoscopy range, a high
signal processing capacity and the functions of user-friendly stethoscopy, recording and playback, intelligent stethoscopy, remote consultation and the like, and can be integrated in other
medical software systems.
