Abstract: A Doppler fetal heartbeat monitor includes: a housing; a mainboard; a loudspeaker installed in the housing and electrically connected to the mainboard; and an ultrasonic transducer installed in the housing, electrically connected to the mainboard, and comprising at least one transduction wafer configured to generate an impulse wave, in which the ultrasonic transducer is internally provided at a head end of the housing, and the loudspeaker and the mainboard are internally provided at a tail end of the housing. By arranging the loudspeaker, the mainboard and the ultrasonic transducer in the housing, the Doppler fetal heartbeat monitor can have a compact structure and a small volume. Moreover, it is possible to reduce positive feedback of a sound system and a probability of a self-excited whistle.

Abstract: The disclosure provides a probe holding table and a medical equipment. The probe holding table comprises a faceplate and a fixing plate for supporting the faceplate. The faceplate is rotatably connected to the fixing plate. A plurality of probe placement units for installing probes are disposed on the faceplate, and each of the probe placement units is in electrical communication with an external power. The user may turn the faceplate to take the probes on the corresponding position, in particular, when more probes need to be used, the structure of the probe holding table is simpler than the normal fixed table, and easier to take the probes. Therefore, the medical equipment adopted the above probe holding table provides with the above advantages.
