Exemplary, the moving circuit of the magnetic latch 423 is preset; sequentially electrifying the second electromagnet 433 on the path of the magnetic clamping block 423 through the control system; attraction is generated on the magnetic clamping block 423, so that the magnetic clamping block 423 is displaced to the position of the second electromagnet 433 which sends out the attraction; such that the sensor 422 can automatically move on the track; thereby measuring different positions on the belly of the pregnant woman; and meanwhile, the sensor 422 is controlled to move through the control system, so that skin discomfort caused by long-term co-location of the sensor 422 can be avoided.
The working principle of the group of non-radiation fetal heart rate instruments provided by the embodiment of the invention is as follows:
The first fixing belt 2 and the second fixing belt 3 are positioned at the upper part and the lower part of the belly of the pregnant woman, and the waist plate 1 is positioned at the waist position of the pregnant woman, so that the pregnant woman is more comfortable to wear;
Secondly, through the length of the bellows 22 at the two ends of the first belt body 21 of the first fixing belt 2 and the second fixing belt 3, the first belt body 21 of the first fixing belt 2 and the second fixing belt 3 is more suitable for the size of the bellyband of the pregnant woman, and the application range is wider.
Then, the control button 23 is pressed, so that the electrocardiograph monitoring device monitors the fetal heart through the sensor 422; exemplary, as shown in fig. 7; when the sensor 422 obtains data through measurement at the position A1, the data are transmitted to the processor for processing, and the processed measurement data are sent to the cloud through the control system; when the data at A2 is required to be measured, the control system is started, the first electromagnet 13 is electrified, and repulsive force is generated on the first magnet 25; the two groups of first belt bodies 21 fixed in the upper cavity 17 and the lower cavity 18 are far away from the first electromagnet 13, so that gaps are formed between the two groups of first belt bodies 21 and the bellies of the pregnant woman, and the sensor 422 is convenient to displace; at this time, the control system energizes the second electromagnet 433 again according to the movement path, for example, to move the sensor 422 from A1 to A5, then energizes the second electromagnet 433 at A1, energizes the second electromagnet 433 at A4, and then generates attraction force on the second electromagnet 433 at A4, so that the sensor 422 moves to A4 under the action of the attraction force, and then energizes the second electromagnet 433 at A4, and loses attraction force; finally, the second electromagnet 433 at the position A5 is electrified to generate attractive force, so that the sensor 422 at the position A4 moves to the position A5, and the electrified state at the position A5 is released, so that the sensor 422 is fixed at the position A5 through the magnetic clamping block 423, the sensor 422 can measure the data at the position A5, and meanwhile, the sensor 422 can also move from the position A5 to the position A3 and then to the position A2. The measuring range is wider, and the data accuracy is higher. At the same time, discomfort caused by the skin at the same place contacting the sensor 422 for a long time can be avoided.
After the sensor 422 moves to the corresponding position, the first electromagnet 13 is not electrified through the control system, the repulsive force disappears, the first magnet 25 and the first electromagnet 13 attract each other, so that the two groups of first belt bodies 21 drive the sensor 422 to be attached to the skin, and fetal heart data measurement is performed.
Although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
