More specifically, in the present embodiment, the two acceleration sensors are respectively disposed on the vibrating diaphragm 19 and the signal converter 11, or respectively disposed on the vibrating diaphragm 19 and the supporting portion 17, and are respectively in flexible contact and rigid contact with the skin of the pregnant woman, and then the data detected by the two acceleration sensors are combined to make a judgment, so as to improve the accuracy in fetal heart detection.

Specifically, in this embodiment, the fetal heart detector takes three current fetal heart monitoring devices, namely, a left fetal heart monitoring device, a middle fetal heart monitoring device and a right fetal heart monitoring device as an example, and the left fetal heart monitoring device and the right fetal heart monitoring device only have the functions of collecting fetal heart sound signals and acceleration sensor signals and transmit the collected signals to the middle fetal heart monitoring device through the connecting line.

The signals of the acceleration sensor are used for judging fetal movement, and finally all the signals are processed in the middle fetal heart monitoring device and then sent out through the wireless transmission module in the middle signal converter 11 in a unified mode.

In the present embodiment, in order to facilitate wiring, the terminal 24 is provided on the signal converter 11, and signal transmission or electrical transmission between a plurality of fetal heart monitoring apparatuses can be facilitated through the terminal 24.

The utility model has the advantages that:

the base body 1 is provided with the plurality of mounting grooves 2, and each mounting groove 2 is internally provided with one tire core monitoring device, so that the plurality of tire core monitoring devices can be simultaneously detected, the detection range is enlarged, and the detection efficiency is improved; and set up connecting hole 8 between adjacent mounting groove 2, can set up the battery in arbitrary mounting groove 2, just need not set up the battery in other mounting grooves 2, reduced whole volume for it is more convenient during the use.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
