Description

Technical Field

[0001] The present invention relates to the technical field of fetal heart rate detection, and more particularly to a fetal heart rate detection device. Background Art

[0002] Fetal heart rate monitoring refers to the use of ultrasound to monitor the condition of the fetus in the uterus, and the formation of a monitoring graph curve through the returned signal so that women or medical staff can check the fetal heart rate response and determine the health status of the fetus.

[0003] Since ultrasonic signals will be greatly attenuated in the atmosphere, the current ultrasonic detection method requires that a coupling agent be applied to the probe before the detection to moisten the skin and eliminate the air on the skin surface, thereby ensuring the propagation efficiency of the ultrasonic wave and improving the detection effect. The operator further holds the probe to find the fetal heart position on the abdominal surface and completes the detection at the fetal heart position. However, the above method still has the following shortcomings during use:

[0028] Preferably, the probe unit 3 includes a lighting component.

[0029] Specifically, the probe unit 3 is a Doppler ultrasonic probe in the prior art, which will not be described in detail here.

[0030] Before use, the probe unit 3 is stored in the storage hole 4. At this time, the magnetic part 7 is adsorbed on the probe unit 3, so that the liquid storage chamber 8 is in an open state, so that the coupling agent in the liquid storage chamber 8 can naturally flow out to the probe unit 3 to complete the application of the probe unit 3. When in use, the belly band 1 is connected to the human body, and the probe unit 3 is further arranged to realize the exploration of the entire abdominal area, and the specific fetal heart position is determined according to the signal.
