[ detailed description ] embodiments

Referring to fig. 1, 2 and 3, the fetal health data monitoring device of the present invention includes a flexible substrate 2, a main magnetostrictive film 3 attached on the flexible substrate, a plurality of compensation magnetostrictive films 4 attached on the flexible substrate and located around the main magnetostrictive film, a main induction coil 7 and a compensation induction coil 6 respectively located on the main magnetostrictive film and the compensation magnetostrictive film, the main induction coil and the compensation induction coil being respectively connected to an input port of a controller 5; the hardware module of controller still includes signal amplifier, current stabilizer, AD converter and the single chip board that the wire connected in proper order, be connected with bluetooth signal transmitter and bee calling organ respectively through the wire on the single chip board, input port and signal amplifier wire connection, the controller still is connected with button cell through the wire.

The two ends of the flexible substrate 2 are connected with the binding bands 1, the binding bands are used for surrounding the waist of the pregnant woman, and the flexible substrate is attached and fixed on the belly of the pregnant woman; the two ends of the binding band are fixed or disassembled in a magic tape mode.

The main magnetostrictive film 3 is a rectangular strip-shaped section, the length of the main magnetostrictive film is 1/3-2/3 of the average value of the waist circumference of the pregnant woman, and the average value of the waist circumference of the pregnant woman refers to a medical data sample.

The main induction coil comprises a plurality of secondary induction coils which are distributed in parallel, and the design can reduce the sectional area of a single coil, so that the detection sensitivity of the piezomagnetic effect is improved.

A relevant program needs to be set in a singlechip board of the controller, the logic of the program contains a judgment algorithm for judging whether a detection signal belongs to effective fetal movement, the input parameters of the judgment algorithm comprise the current value of any secondary induction coil (namely the current value of a main induction coil) and the current values of all compensation induction coils, when the main induction coil detects the current value, the controller needs to judge whether the compensation induction coil has detection current exceeding a certain threshold value, if the compensation induction coil has obvious current, the action is initiated by a pregnant woman and does not belong to the effective fetal movement; on the contrary, if only local sudden action exists and the main induction coil detects the current value, the compensation induction coil does not generate a remarkable current value, the effective fetal movement is judged at the moment, and a counter in the single chip microcomputer board counts; when the singlechip board does not detect the number of fetal movements of setting for the threshold value in a certain time, then can control bee calling organ and send out alarm sound, if the cell-phone is in the connection status of pairing with bluetooth module, can receive the alarm signal who is sent by bluetooth signal transmitter through APP.

According to the invention, the magnetostrictive film is close to the belly of a pregnant woman by taking the flexible substrate as a carrier, and a piezomagnetic effect is generated when fetal movement is generated, so that induced current is generated as a detection signal, and the fetal movement is monitored; by arranging a plurality of compensation magnetostrictive films as reference, the difference between real fetal movement and the movement of the pregnant woman body can be effectively identified, and the reliability of fetal movement monitoring is improved
