[0002] To monitor the health status of the fetus in the mother's body, with the advancement of medical technology, fetal heart rate monitors have gradually appeared and have been widely used. Modern fetal heart rate monitors not only have the ability to monitor the fetal heartbeat with high precision and in real time, but also integrate multiple physiological parameter monitoring functions such as uterine contraction pressure and fetal movement frequency, providing clinicians with richer and more comprehensive fetal physiological information. However, when the fetus is undergoing fetal heart rate monitoring, the fetus needs to remain awake. Therefore, for some fetuses that are asleep, in daily life, pregnant women are usually required to get up and exercise, or medical staff need to wake the fetus up by knocking on objects that make sounds.

[0003] For example: The Chinese invention patent (application number: CN202110018298.9) discloses a "fetal heart rate monitoring device and method for clinical use by obstetricians and gynecologists". Its specification discloses: When performing a fetal heart rate examination, the examination needs to be performed while the fetus is awake. However, in the actual detection process, the fetus is often in a sleeping state, so the fetus needs to be awakened. The current awakening methods are mostly to perform appropriate amounts of exercise and shake the pregnant woman's belly with appropriate force.

[0044] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0045] Example 1, please refer to Figure 1-Figure 9A fetal heart monitoring device for clinical use by obstetricians and gynecologists comprises a seat 1, the seat 1 comprises a suspension 102 and a slider 103, a positioning mechanism 3 is slidably installed in the middle of the suspension 102, a monitoring mechanism 2 is arranged at the bottom of the positioning mechanism 3, the monitoring mechanism 2 comprises a support block 201, a probe 206 is sleeved in the middle of the bottom of the support block 201, a cavity is arranged inside the probe 206, four mounting grooves 211 are opened at equal angles on the side of the support block 201, a guide plate 208 is movably hinged inside the mounting groove 211, a knocking rod 209 is fixedly installed on the inner side of the top of the guide plate 208, the knocking rod 209 is magnetic, and the probe 206 A conduit 207 is fixedly connected in the middle of the top, and four support springs 210 are fixedly installed at equal angles on the top of the probe 206. The top of the support spring 210 is fixedly connected to the top of the inner cavity of the support block 201. A gear ring 202 is rotatably sleeved on the outer side of the top of the support block 201. A sealing sleeve 203 is fixedly installed on the bottom of the gear ring 202. A wave ring 204 is fixedly installed on the inner side of the bottom of the sealing sleeve 203. The wave ring 204 is pressed on the outer side of the bottom end of the guide plate 208. A rotating groove 212 is opened on the side of the support block 201. The wave ring 204 is rotatably clamped in the inside of the rotating groove 212. The side of the top of the support block 201 is fixedly installed A motor 213 is installed, the output end of the motor 213 is fixedly connected to a gear and meshed with a gear ring 202. Lifting armrests 101 are provided on both sides of the seat 1. One end of the suspension 102 is movably hinged to the inner side of the lifting armrest 101 on one side, and the other end is clamped to the inner side of the other lifting armrest 101. A sliding groove 105 is opened in the middle of the suspension 102. The positioning mechanism 3 is slidably clamped on the top of the suspension 102. The bottom of the support block 201 is fixedly connected to an adsorption plate 205. The probe 206 is sleeved on the inner top of the adsorption plate 205. The adsorption plate 205 and the probe 206 are connected by rubber. When the position of the fetal heart monitoring is determined Finally, the suction plate 205 on the outside of the probe 206 comes into contact with the belly of the pregnant woman, and then the probe 206 is attached to the belly of the pregnant woman. At this time, the catheter 207 is pulled upward, which will cause the probe 206 to move up synchronously, and then the belly of the pregnant woman is adsorbed between the suction plate 205 and the probe 206. At this time, the guide plates 208 on the four sides of the probe 206 support the guide plates 208 outward when the probe 206 moves up, so that the guide plates 208 seal and cover the installation groove 211, thereby achieving sealing of the inside of the support block 201, thereby reducing the impact of the external environment on fetal heart monitoring, and at the same time increasing the strength of fetal heart monitoring collected by the probe 206.

[0046] In order to solve the problem in the prior art that when the fetus is undergoing fetal heart monitoring, the monitoring is not clear enough and errors occur due to the bottom of the monitoring head not being in close contact with the belly, the present application fixes the catheter 207 with the probe 206, and connects the probe 206 to the adsorption plate 205 at the bottom of the support block 201 through rubber. By moving the catheter 207 upward, the probe 206 is moved upward, and then the probe 206 and the adsorption plate 205 tightly adsorb the pregnant woman's belly inside, so that the monitoring of the monitoring head is clearer, thereby improving the monitoring effect and quality.

[0047] Please refer to Figure 1-Figure 3 and Figure 6 A fetal heart rate monitoring device for clinical use by obstetricians and gynecologists, wherein a motor 213 is fixedly mounted on the top of a support block 201, and is slidably engaged in a sliding groove 105 opened in the middle of a suspension 102 to guide and limit a monitoring mechanism 2. The top of the support block 201 is attached to the bottom of the suspension 102, and the bottom of the slider 103 is attached to the top of the suspension 102. The monitoring mechanism 2 can move along a predetermined trajectory through the limit on both sides. A guide plate 208 is movably hinged in the interior of a mounting groove 211. A knocking rod 209 at the top of the guide plate 208 is tilted to the top of a probe 206 by magnetic adsorption. The bottom of the wave ring 204 is made of The wave-shaped design squeezes the outer side of the bottom end of the guide plate 208. By squeezing the outer side of the guide plate 208, the top of the guide plate 208 is lifted. When the squeezing of the outer side of the guide plate 208 is lost, the knocking rod 209 on the inner side of the top of the guide plate 208 will automatically move downward and hit the top of the probe 206 under the effect of magnetic adsorption. A cavity is opened inside the probe 206, so that the probe 206 produces a sound when it is knocked. Through the wave-shaped design, the outer side of the guide plate 208 can be continuously squeezed, so that the guide plate 208 is continuously shaken, thereby continuously making the probe 206 produce a sound.

[0048] Example 2 further optimizes the fetal heart rate monitoring device for obstetricians and gynecologists provided in Example 1. Specifically, Figure 4 and Figure 6As shown, the positioning mechanism 3 includes a rotating ring 301 and a limiting plate 305, the slider 103 is slidably clamped on the top of the suspension 102, the rotating ring 301 is rotatably sleeved on the top of the guide tube 207, the rotating ring 301 is rotatably clamped on the top of the slider 103, and the side of the rotating ring 301 is provided with a limiting rod 308 at equal angles through a spring, and the outer side of the limiting rod 308 is fixedly connected with a button 307, and the outer end of the button 307 extends from the side of the rotating ring 301, and the top of the slider 103 is provided with a limiting groove 104 at equal angles, and the bottom of the limiting rod 308 is clamped inside the limiting groove 104, The positioning plate 305 is fixedly installed on the catheter 207 and slidably engaged in the interior of the sliding groove 105. The top of the inner cavity of the sliding groove 105 is equidistantly provided with positioning holes 106. A pair of positioning rods 306 are symmetrically installed on the top of the limiting plate 305. The positioning rods 306 move upward and engage in the interior of the positioning holes 106. The bottom of the rotating ring 301 is fixedly connected to the driving ring 302. The inner side of the bottom of the driving ring 302 is fixedly installed with an active extrusion block 303. The middle part of the catheter 207 is fixedly installed with a passive extrusion block 304. The active extrusion block 303 is rotatably engaged with the bottom of the passive extrusion block 304. The opposite surfaces of the extrusion block 303 and the passive extrusion block 304 are both wavy in design, and the two are adapted to each other. When the active extrusion block 303 rotates, the top of the active extrusion block 303 contacts the bottom of the passive extrusion block 304, and the passive extrusion block 304 is pushed up and the catheter 207 and the probe 206 are pushed up. By moving the slider 103, the movement of the monitoring mechanism 2 at the bottom is controlled, so that the probe 206 is constantly fitted with different positions on the pregnant woman's belly, and then the fetal heart rate monitoring is performed until the correct position is found and then the limit rod 308 is moved inward by pressing the button 307. Push sideways to make the limiting rod 308 disengage from the inner side of the limiting groove 104, and then rotate the rotating ring 301 to make the active extrusion block 303 at the bottom of the rotating ring 301 squeeze the passive extrusion block 304 in the catheter 207, so that the positioning rod 306 at the top of the limiting plate 305 is inserted into the inner side of the positioning hole 106 at the top of the sliding groove 105, and then the monitoring mechanism 2 is positioned. At this time, the catheter 207 pushes the probe 206 upward while moving upward, so that the adsorption plate 205 cooperates with the probe 206, and the adsorption plate 205 is adsorbed on the belly, so that the monitoring mechanism 2 is fixed at the monitoring point.

[0049] By cooperating with each other through the positioning mechanism 3 and the catheter 207, after the suction plate 205 moves to the specified position, the limiting rod 308 is squeezed inward by pressing the button 307, thereby moving the catheter 207 upward, so that after the control slider 103 moves to the specified position, the positioning rod 306 and the positioning hole 106 are engaged with each other, thereby limiting and fixing the position of the suction plate 205 and the probe 206, and at the same time, pulling the catheter 207 and the probe 206 upward, thereby improving the fit between the probe 206 and the belly, thereby facilitating the positioning and movement of the monitoring mechanism 2, and solving the problem of inconvenient movement and positioning of the monitoring mechanism 2 in the prior art.

[0050] The use process of the fetal heart rate monitoring device for clinical use by obstetricians and gynecologists provided by the present invention is as follows:

[0051] By moving the slider 103, the monitoring mechanism 2 at the bottom is controlled to move, so that the probe 206 is constantly fitted with different positions on the pregnant woman's belly, and then the fetal heart rate monitoring is performed until the correct position is found. Then, by pressing the button 307, the limiting rod 308 is pushed inward, so that the limiting rod 308 is disengaged from the inner side of the limiting groove 104, and then by rotating the rotating ring 301, the active extrusion block 303 at the bottom of the rotating ring 301 squeezes the passive extrusion block 304 in the catheter 207, so that the positioning rod 306 at the top of the limiting plate 305 is stuck in the inner side of the positioning hole 106 at the top of the sliding groove 105, and then the monitoring mechanism 2 is positioned. At this time, the catheter 207 pushes the probe 206 upward while moving upward, so that the adsorption plate 205 cooperates with the probe 206, so that the adsorption plate 205 is adsorbed on the belly, so that the monitoring mechanism 2 is fixed at the monitoring point. At this time, the guide plates 208 on the four sides of the probe 206 are on the probe 20 When the guide plate 208 is moved upward, the guide plate 208 is supported outward, so that the guide plate 208 seals and blocks the mounting groove 211, thereby achieving sealing of the inside of the support block 201, thereby reducing the impact of the external environment on the fetal heart monitoring, and at the same time increasing the strength of the fetal heart monitoring collected by the probe 206. When the fetus needs to be awakened, the probe 206 is attached to the belly of the pregnant woman, and then the motor 213 drives the gear ring 202 to rotate, so that the sealing sleeve 203 pulls the wave ring 204 at the bottom to rotate, and then the wave ring 204 squeezes the outer side of the bottom end of the guide plate 208, so that the guide plate 208 is constantly shaking. Every time the top of the guide plate 208 is lifted, when the squeezing of the wave ring 204 is lost, the knocking rod 209 on the inside of the guide plate 208 will hit the top of the probe 206 under the action of magnetic attraction, so that the probe 206 vibrates and makes a sound, thereby awakening the fetus in the pregnant woman's belly.
