Description

technical field [0001] The invention relates to the technical field of medical imaging devices, in particular to a bluetooth-based all-digital Doppler fetal heart rate wireless probe and a detection method. Background technique [0002] At present, the fetal monitoring equipment commonly used in the home market is mainly ultrasonic Doppler fetal heart monitoring products. This type of product is simple in structure and easy to use. Users can use it to listen to fetal heart Doppler signals and obtain their heart rate. Information, market acceptance is high. However, due to the simple structure and single function of this type of equipment, some motion dynamic parameters of the fetal heartbeat cannot be obtained, which limits its further application. The fetal monitoring equipment used in hospitals can detect some blood flow and tissue dynamics information, but it is expensive, and the equipment is bulky and inconvenient to move. Moreover, this type of equipment does not open...
