Description

Technical Field

[0001] The present invention relates to the technical field of fetal heart rate monitoring, and specifically to a fetal heart rate monitoring device for special delivery positions of parturients. Background Art

[0002] As is well known, fetal heart rate monitoring records the changes in the fetal heart rate through an instrument, and at the same time observes the uterine contractions and fetal movements to judge whether there are abnormal conditions such as hypoxia in the fetus in the uterus. During the delivery process, the environment faced by the fetus will change in various ways. Uterine contractions will exert pressure on the placenta and umbilical cord, which may affect the oxygen and nutrient supply of the fetus.

[0003] When performing fetal heart rate monitoring, a fetal heart rate monitoring device is required. The problems existing in the prior art are as follows: when the parturient adopts special delivery positions such as the lateral lying position and the kneeling position, it is often difficult to accurately and stably monitor the fetal heart rate, and problems such as signal loss or interference are likely to occur. Moreover, different from previous examinations, the abdomen of the parturient will deform according to the delivery process during childbirth. Usually, the method of bonding the probe with adhesive tape is likely to cause loosening and other situations, and it is inconvenient to use; Chinese Patent: CN119112236B discloses an intelligent fetal heart rate monitoring device for obstetrics and gynecology. By controlling the movement of the moving ring, negative pressure is generated in the rubber ring, and then the monitoring probe is adsorbed on the abdomen of the pregnant woman, making the entire fixing process faster and more convenient. At the same time, it is no longer necessary for the pregnant woman to make a lumbar lifting movement and use an elastic band for fixation, improving the comfort of the pregnant woman during the monitoring process; Although the above-mentioned intelligent fetal heart rate monitoring device for obstetrics and gynecology realizes the rapid fixation of the monitoring probe device on the abdomen of the pregnant woman, during the obstetrics and gynecology examination actions, the position of the pregnant woman may be adjusted according to the actual situation. At this time, the abdominal contour of the pregnant woman also changes, but the flexibility of its device is limited.

[0004] Based on the above-mentioned situations, we found that it is very difficult for the existing fetal heart rate monitoring devices to avoid the above problems at the same time. Even if they can be solved, it is necessary for personnel to hold the probe in real time, which is not only easy to displace, but also the excessive movement may cause irritation to the parturient. It is more difficult to hold in positions such as the kneeling position to maintain continuous monitoring. Therefore, we propose a special delivery position fetal heart rate monitoring device that reduces the pressure on the parturient, can stably monitor the fetal heart rate in multiple positions at the same time, and can remotely control the probe to displace to a certain extent when it is inconvenient for personnel to adjust the monitoring position. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a fetal heart rate monitoring device for special delivery positions of parturients, which has the advantages of reducing the pressure on the parturient, being able to stably monitor the fetal heart rate in multiple positions at the same time, and being able to remotely control the probe to displace to a certain extent when it is inconvenient for personnel to adjust the monitoring position.

[0006] The above technical object of the present invention is achieved by the following technical solutions: A fetal heart rate monitoring device for the special delivery position of parturients, including a monitoring part, a fixing part and an adjusting part. The fixing part includes an abdominal belt. The monitoring part is arranged inside the fixing part. Auxiliary belts are sewn on both sides of the abdominal belt. An outer hoop is fixedly connected to the outside of the abdominal belt. Shoulder straps are arranged on both sides of the rear side of the outer hoop. One side of the shoulder strap away from the abdominal belt is movably connected to the auxiliary belt. A connecting strip is arranged on the front side of the outer hoop. A leg strap is sewn on the front side of the connecting strip. An elastic net is sewn on the inside of the outer hoop. One side of the elastic net close to the abdominal belt is sewn to the abdominal belt; The adjusting part includes a silica gel guide rail sewn on the top of the abdominal belt and a fitting piece sewn on the top of the abdominal belt. A silica gel guide rod is fixedly connected to the top of the fitting piece. An active component is arranged inside the silica gel guide rail. A horizontal frame is fixedly connected to the top of the active component. The inside of the horizontal frame is movably connected to the monitoring part. A sliding sleeve is fixedly connected to the front side of the horizontal frame. The inside of the sliding sleeve is sleeved with the silica gel guide rod. The sliding sleeve and the silica gel guide rod are in clearance fit; The monitoring part includes a carrier plate. An annular probe is installed inside the carrier plate. An annular airbag is fixedly connected to the top of the carrier plate. A sliding frame is fixedly connected to the top of the annular airbag. The inside of the sliding frame is slidably connected to the horizontal frame. An electric cylinder is fixedly connected to the top of the sliding frame. The bottom of the electric cylinder is movably connected to the annular probe. A content structure is arranged inside the annular probe; The content structure includes a container outer shell and a container inner shell. The container inner shell and the container outer shell are integrally formed. A pressing bead is movably connected to the inside of the container inner shell. A hollow rod is fixedly connected to the top of the pressing bead. A pressing spring is arranged inside the hollow rod. A piston ring is slidably connected to the outside of the container inner shell. A pushing spring is fixedly connected to the bottom of the piston ring.

[0007] With the above technical solution, by setting the fixing part, when in use, it can be attached to the abdomen of the parturient through the abdominal belt. At this time, the empty position inside the abdominal belt is the position of the monitoring part, and the bottom of the monitoring part is attached to the abdomen of the parturient. The outer hoop outside the abdominal belt covers the outside of the abdominal bulge, and the elastic net covers the entire abdomen of the parturient and undergoes elastic deformation to fit the shape of the pregnant woman's abdomen. Then, the auxiliary belt is placed behind the parturient along both sides of the abdomen of the parturient and fixed. Cross the two shoulder straps at the back of the parturient and fix them on the outer hoop from the front of the parturient along the shoulders to pull the top position of the outer hoop. Then, wrap the leg straps around the thighs of the parturient and pull the outer hoop through the connecting strip to achieve the effect of expanding the outer hoop and fixing the position of the structure. With a wearable design and the ability to fit the body contour of the parturient, it can effectively reduce the pressure on the parturient during fixation, be more stable, and be more convenient to disassemble. Compared with direct pasting, it can also reduce discomfort. By setting the carrier plate in cooperation with the annular probe, the annular probe can better fit the abdomen of the parturient. When monitoring, gas can be inflated into the annular airbag to make the annular airbag expand and increase in volume until the bottom annular probe stably contacts the abdomen of the parturient. When the monitoring position is relatively inclined and difficult to fix, the probe can be pulled by the electric cylinder to compress the airbag at the pulling position, so that the bottom of the probe also tilts to fit the monitoring position. The set content structure can assist in applying the ultrasonic coupling agent. Before monitoring, hold the monitoring part and gently press and move it repeatedly at the abdominal position of the parturient that needs to be monitored. When pressing, the pressing beads are pressed into the inner shell of the container. At this time, the hollow rod is pressed and shortened, and the pressing spring stores energy. Since a gap is generated between the inner shell of the container and the pressing beads, the pressure at the opening decreases. Therefore, the pushing spring can push the piston ring to displace. During the displacement process, the ultrasonic coupling agent will be extruded from the top of the piston ring and squeezed out between the pressing beads and the inner shell of the container. During the repeated movement process, the annular probe will apply the ultrasonic coupling agent to the monitoring position to avoid the situation where it is difficult to apply when the parturient adopts a kneeling and lying position. After the parturient completes wearing and fixing through the fixing part, the sliding carriage can be horizontally moved along the horizontal frame according to the required monitoring position to complete the position adjustment. When position adjustment is required during the monitoring process, the active component can be controlled to displace inside the silicone guide rail. At this time, the active component drags the horizontal frame for position adjustment. When the horizontal frame moves, it is limited by the sliding sleeve on the silicone guide rod, so it will not tilt at too large an angle. This method controls the active component for position adjustment, and the monitoring position can also be changed when it is difficult for medical staff to adjust in some body positions.

[0008] The present invention is further configured as: the shoulder strap includes a non-woven fabric belt body. On one side of the non-woven fabric belt body close to the outer hoop, a male snap fastener is installed. On both sides of the rear side of the outer hoop, female snap fasteners are installed. The male snap fastener and the female snap fastener are snap-connected, and the two shoulder straps are respectively sewn to the two auxiliary belts.

[0009] With the above technical solution, by setting the non-woven fabric belt body to bypass the shoulders of the wearer during wearing, and the male plug can be inserted into the female socket for quick installation or disassembly, and being respectively connected to the two auxiliary belts can facilitate crossing behind the parturient during wearing, so as to avoid slipping from both sides of the parturient's shoulders during wearing.

[0010] The present invention is further configured as follows: a first hook-and-loop fastener rough surface is sewn at the bottom of the left auxiliary belt, and a first hook-and-loop fastener hook surface is sewn at the top of the right auxiliary belt, and the first hook-and-loop fastener rough surface and the first hook-and-loop fastener hook surface are adhered.

[0011] With the above technical solution, by setting the first hook-and-loop fastener rough surface in cooperation with the first hook-and-loop fastener hook surface, it can facilitate fixing the auxiliary belt behind the parturient. The fixing process does not require excessive pulling, avoiding causing pressure on the waist and abdomen of the parturient.

[0012] The present invention is further configured as follows: the rear side of the connecting strip is sewn to the outer hoop, and an adjusting belt buckle is movably connected to the outer side of the connecting strip.

[0013] With the above technical solution, by setting the adjusting belt buckle, it can facilitate adjusting the length of the connecting strip according to the body type of the parturient, avoiding the failure of the fixing effect caused by being too long or causing pressure on the legs or abdomen of the parturient due to being too short.

[0014] The present invention is further configured as follows: a second hook-and-loop fastener hook surface is sewn at the top of the leg strap, a second hook-and-loop fastener rough surface is sewn at the bottom of the leg strap, and the second hook-and-loop fastener hook surface and the second hook-and-loop fastener rough surface are adhered.

[0015] With the above technical solution, by setting the second hook-and-loop fastener hook surface in cooperation with the second hook-and-loop fastener rough surface, it can facilitate fixing the leg strap on the leg of the parturient.

[0016] The present invention is further configured as follows: the active component includes a control motor, a suspension is fixedly connected to the rear side of the control motor, the top of the suspension is fixedly connected to the horizontal frame, the output end of the control motor is rotatably connected to the suspension, a telescopic sleeve is fixedly connected to the outside of the output end of the control motor, an eccentric outer ring is fixedly connected to the side of the telescopic sleeve away from the control motor, a friction ring is fixedly connected to the outside of the eccentric outer ring, anti-slip grooves are formed on the surface of the friction ring, a friction plate is provided at the bottom of the friction ring, the bottom of the friction plate is fixedly connected to the silicone guide rail, a silicone cross bar is fixedly connected to the inside of the silicone guide rail, the outside of the silicone cross bar is sleeved with the inside of the suspension, and the suspension and the silicone cross bar are in clearance fit.

[0017] With the above technical solution, by setting a control motor to provide power, when in use, it can drive the telescopic sleeve and the eccentric outer ring connected thereto to rotate. The friction ring on the outer side of the eccentric outer ring contacts the friction plate, and drives the friction ring to move along the silicone guide rail through friction. While moving, it is restricted by the suspension and the limit of the silicone cross bar, so it is not easy to tilt or fall off. The control motor directly connected to the suspension can also be in a relatively stable operating state.

[0018] The present invention is further configured as: the telescopic sleeve includes two outer sleeves fixedly connected to the outer side of the output shaft of the control motor. An empty cylinder is fixedly connected to the inner side of the outer sleeve. Flow holes are provided at the top and bottom of the inner side of the empty cylinder. A piston piece is slidably connected to the inner side of the empty cylinder. The inner side of the empty cylinder is filled with hydraulic fluid. A telescopic rod is fixedly connected to the outer side of the piston piece. The outer side of the telescopic rod is slidably connected to the outer sleeve. The side of the telescopic rod away from the empty cylinder is fixedly connected to the eccentric outer ring. A return spring is sleeved on the outer side of the telescopic rod. The side of the return spring close to the outer sleeve is fixedly connected to the outer sleeve. The inner side of the outer sleeve is slidably connected to the telescopic rod through a oil seal.

[0019] With the above technical solution, by setting the outer sleeve to cooperate with the empty cylinder, the telescopic rod is connected to the empty cylinder through the piston piece. Since the eccentric outer ring is pressed under the contact of the friction ring and the friction plate, it always maintains an eccentric state relative to the output end of the control motor. When it is necessary to drive the movement, the control motor drives the telescopic sleeve to rotate. Even if the eccentric outer ring and the friction ring rotate and move along the friction plate, and when the movement stops, since the friction plate is closer to the parturient's abdomen and fits the parturient's abdomen, the friction plate will press the friction ring and be pushed relative to the output end of the control motor. During the pushing process, the telescopic rod and the piston piece displace along the empty cylinder, and push the internal fluid to flow along the flow hole to play a damping effect. Limited by the flow rate under the continuous rotation of the control motor, the friction ring and the output end of the control motor relatively maintain a concentric state. After stopping, the return spring pushes the piston piece and the telescopic rod to reset, so that the eccentric outer ring is in an eccentric state, which not only plays the effect of keeping the structure stationary and not easy to displace, but also can reduce the pressure on the parturient's abdomen.

[0020] The present invention is further configured as: the telescopic end of the electric cylinder penetrates through the sliding frame and is fixedly connected to a rotating shaft. The bottom of the rotating shaft is fixedly connected to the annular probe.

[0021] With the above technical solution, by setting the rotating shaft, when the electric cylinder pulls the annular probe, there can be a certain displacement space, and at the same time, the structure can rotate at a certain angle relatively.

[0022] The present invention is further configured as: a filling valve is fixedly connected to the top of the container outer shell. A hollow column is fixedly connected to the top of the container inner shell. The top of the hollow column is fixedly connected to the container outer shell.

[0023] With the above technical solution, by providing a filling valve, it is convenient to fill the ultrasonic coupling agent into the interior of the container housing. The provided hollow column can support the structure while allowing the ultrasonic coupling agent to flow.

[0024] The present invention is further configured such that: a fastening screw is provided inside the carriage, and the bottom of the fastening screw is movably connected to the horizontal frame.

[0025] With the above technical solution, by providing the fastening screw, after the carriage slides along the horizontal frame to the desired position, the relative position between the structures is fixed by tightening the fastening screw.

[0026] Compared with the prior art, the present invention provides a fetal heart rate monitoring device for special delivery positions of parturients, having the following beneficial effects: This fetal heart rate monitoring device for special delivery positions of parturients can be attached to the abdomen of the parturient through an abdominal belt by setting a fixing part. At this time, the empty position inside the abdominal belt is the position of the monitoring part, and the bottom of the monitoring part is attached to the abdomen of the parturient. The outer hoop on the outside of the abdominal belt covers the outside of the abdominal bulge, and the elastic net covers the entire abdomen of the parturient and elastically deforms to fit the shape of the pregnant woman's abdomen. Then, the auxiliary belt is placed behind the parturient along both sides of the abdomen and fixed. Two shoulder straps are crossed at the back of the parturient and fixed to the outer hoop from the front of the parturient along the shoulders to pull the top position of the outer hoop. Then, the leg straps are wound around the thighs of the parturient, and the outer hoop is pulled through the connecting strip to expand the outer hoop and fix the position of the structure. The wearable design can fit the body contour of the parturient, effectively reducing the pressure on the parturient during fixation, being more stable, and being more convenient to disassemble. Compared with direct pasting, it can also reduce discomfort. By setting a carrier plate and a circular probe, the circular probe can better fit the abdomen of the parturient. When monitoring, gas can be inflated into the circular airbag to make the circular airbag expand and increase in volume until the bottom circular probe firmly contacts the abdomen of the parturient. When the monitoring position is relatively inclined and difficult to fix, the probe can be pulled by an electric cylinder to compress the airbag at the pulling position, so that the bottom of the probe also tilts to fit the monitoring position. The set content structure can assist in applying the ultrasonic coupling agent. Before monitoring, the monitoring part can be held and gently pressed and repeatedly moved at the abdominal position of the parturient that needs to be monitored. When pressing, the pressing beads are pressed into the inner shell of the container. At this time, the hollow rod is pressed and shortened, and the pressing spring stores energy. Since a gap is generated between the inner shell of the container and the pressing beads, the pressure at the opening decreases. Therefore, the pushing spring can push the piston ring to displace. During the displacement process, the ultrasonic coupling agent will be extruded from the top of the piston ring and squeezed out between the pressing beads and the inner shell of the container. During the repeated movement process, the circular probe will apply the ultrasonic coupling agent to the monitoring position, avoiding the situation where it is difficult to apply when the parturient adopts a kneeling and lying position. After the parturient completes wearing and fixing through the fixing part, the carriage can be horizontally moved along the horizontal frame according to the monitoring position required to complete the position adjustment. When position adjustment is required during the monitoring process, the active component can be controlled to displace inside the silicone guide rail. At this time, the active component drags the horizontal frame for position adjustment. When the horizontal frame moves, it is limited by the sliding sleeve on the silicone guide rod, so it will not tilt at too large an angle. This method can change the monitoring position by controlling the active component, even when it is difficult for medical staff to adjust in some positions. Brief Description of the Drawings

Before monitoring, the monitoring part 1 can be held and gently pressed and repeatedly moved several times at the abdominal position of the parturient that needs to be monitored. When pressing, the bead 163 is pressed into the inner shell 162 of the container. At this time, the hollow rod 164 is pressed and shortened, and the pressing spring 165 stores energy. Since a gap is generated between the inner shell 162 of the container and the bead 163, the pressure at the opening decreases. Therefore, the pushing spring 167 can push the piston ring 166 to displace. During the displacement process, the ultrasonic coupling agent will be squeezed from the top of the piston ring 166 and extruded from between the bead 163 and the inner shell 162 of the container. During the repeated movement process, the annular probe 12 will apply the ultrasonic coupling agent to the monitoring position, avoiding the situation where it is difficult to apply when the parturient adopts a kneeling and lying position, etc. After the parturient is fixed and worn through the fixing part 2, the carriage 14 can be horizontally moved along the horizontal frame 35 according to the required monitoring position to complete the position adjustment. When position adjustment is required during the monitoring process, the active component 34 can be controlled to displace inside the silicone guide rail 31. At this time, the active component 34 drags the horizontal frame 35 to adjust the position. When the horizontal frame 35 moves, it is limited by the sliding sleeve 36 on the silicone guide rod 33, so it will not tilt at too large an angle. This method controls the active component 34 to adjust the position, and the monitoring position can also be changed when it is difficult for medical staff to adjust in some body positions.

[0034] Among them, the active component 34 includes a control motor 341. A suspension 342 is fixedly connected to the rear side of the control motor 341. The top of the suspension 342 is fixedly connected to the horizontal frame 35. The output end of the control motor 341 is rotatably connected to the suspension 342. An expansion sleeve 343 is fixedly connected to the outside of the output end of the control motor 341. One side of the expansion sleeve 343 away from the control motor 341 is fixedly connected to an eccentric outer ring 344. A friction ring 345 is fixedly connected to the outside of the eccentric outer ring 344. Anti-slip grooves are formed on the surface of the friction ring 345. A friction plate 346 is provided at the bottom of the friction ring 345. The bottom of the friction plate 346 is fixedly connected to the silicone guide rail 31. A silicone cross bar 347 is fixedly connected to the inside of the silicone guide rail 31. The outside of the silicone cross bar 347 is sleeved with the inside of the suspension 342. There is a clearance fit between the suspension 342 and the silicone cross bar 347. By setting the control motor 341 to provide power, the expansion sleeve 343 and the eccentric outer ring 344 connected thereto can be driven to rotate during use. The friction ring 345 on the outside of the eccentric outer ring 344 contacts the friction plate 346, and the friction ring 345 is driven to move along the silicone guide rail 31 through the frictional force. During the movement, it is restricted by the limit of the suspension 342 and the silicone cross bar 347. Therefore, it is not easy to tilt or fall off. The control motor 341 directly connected to the suspension 342 can also be in a relatively stable operating state. The expansion sleeve 343 includes two outer sleeves 3431 fixedly connected to the outside of the output shaft of the control motor 341. A hollow cylinder 3432 is fixedly connected to the inside of the outer sleeve 3431. Flow holes 3433 are formed at the top and bottom of the inside of the hollow cylinder 3432. A piston piece 3434 is slidably connected to the inside of the hollow cylinder 3432. The inside of the hollow cylinder 3432 is filled with hydraulic fluid. A telescopic rod 3435 is fixedly connected to the outside of the piston piece 3434. The outside of the telescopic rod 3435 is slidably connected to the outer sleeve 3431. One side of the telescopic rod 3435 away from the hollow cylinder 3432 is fixedly connected to the eccentric outer ring 344. A return spring 3436 is sleeved on the outside of the telescopic rod 3435. One side of the return spring 3436 close to the outer sleeve 3431 is fixedly connected to the outer sleeve 3431. The inside of the outer sleeve 3431 is slidably connected to the telescopic rod 3435 through a oil seal. By setting the outer sleeve 3431 to cooperate with the hollow cylinder 3432, the telescopic rod 3435 is connected to the hollow cylinder 3432 through the piston piece 3434. Since the eccentric outer ring 344 is pressed under the contact of the friction ring 345 and the friction plate 346, it always maintains an eccentric state relative to the output end of the control motor 341. When it is necessary to drive the movement, the control motor 341 drives the expansion sleeve 343 to rotate, so that the eccentric outer ring 344 and the friction ring 345 rotate and move along the friction plate 346. When the movement stops, since the friction plate 346 is closer to the parturient's abdomen and fits the parturient's abdomen, the friction plate 346 will press the friction ring 345 and be pushed relative to the output end of the control motor 341. During the pushing process, the telescopic rod 3435 and the piston piece 3434 displace along the hollow cylinder 3432.And it promotes the internal fluid to flow along the flow hole 3433 to achieve a damping effect. Limited by the flow velocity under the continuous rotation of the control motor 341, the friction ring 345 and the output end of the control motor 341 relatively maintain a concentric state. After being stationary, the return spring 3436 pushes the piston piece 3434 and the telescopic rod 3435 to reset, making the eccentric outer ring 344 in an eccentric state. This not only achieves the effect of keeping the structure stationary and not easily displaced, but also can reduce the pressure on the abdomen of the parturient. The telescopic end of the electric cylinder 15 penetrates through the carriage 14 and is fixedly connected to a rotating shaft 9. The bottom of the rotating shaft 9 is fixedly connected to the annular probe 12. By setting the rotating shaft 9, there can be a certain displacement space when the electric cylinder 15 pulls the annular probe 12, and at the same time, the structure can relatively rotate by a certain angle. The top of the container outer shell 161 is fixedly connected to a filling valve 10. The top of the container inner shell 162 is fixedly connected to a hollow column, and the top of the hollow column is fixedly connected to the container outer shell 161. By setting the filling valve 10, it is convenient to fill the ultrasonic coupling agent into the interior of the container outer shell 161. The provided hollow column can supply the flow of the ultrasonic coupling agent while supporting the structure. The inner side of the carriage 14 is provided with a fastening screw, and the bottom of the fastening screw is movably connected to the horizontal frame 35. By setting the fastening screw, after the carriage 14 slides along the horizontal frame 35 to the required position, the relative position between the structures is fixed by tightening the fastening screw.,

[0035] Working principle of this embodiment: Attach the abdominal belt 21 to the abdomen of the parturient, so that the monitoring part 1 is located at the vacant position inside the abdominal belt 21, and the bottom of the monitoring part 1 is attached to the abdomen of the parturient. After wearing and fixing, hold the monitoring part 1 and gently press and move it repeatedly at the abdominal position to be monitored by the parturient. When pressing, the pressure bead 163 is pressed into the inner shell 162 of the container, the hollow rod 164 is pressed and shortened, the pressure spring 165 stores energy, a gap is generated between the inner shell 162 of the container and the pressure bead 163, the pressure at the opening decreases, and the push spring 167 pushes the piston ring 166 to displace. The ultrasonic coupling agent is extruded from the top of the piston ring 166 and extruded from between the pressure bead 163 and the inner shell 162 of the container. The annular probe 12 smears the ultrasonic coupling agent at the monitoring position during repeated movement. Move the carriage 14 horizontally along the horizontal frame 35 according to the position required for monitoring. After reaching the appropriate position, tighten the fastening screw inside the carriage 14 to fix the relative positions between the fixing structures. If position adjustment is required during the monitoring process, start the control motor 341 of the active component 34 to drive the telescopic sleeve 343 and the eccentric outer ring 344 to rotate. The friction ring 345 on the outside of the eccentric outer ring 344 contacts the friction plate 346, and the friction ring 345 is driven to move along the silicone guide rail 31 through the frictional force, driving the horizontal frame 35 and the monitoring part 1 to displace. When moving, restricted by the limit of the suspension 342 and the silicone cross bar 347, the structure is not likely to tilt or fall off. When the movement stops, the friction plate 346 presses against the friction ring 345, and the telescopic rod 3435 and the piston plate 3434 displace along the empty cylinder 3432, pushing the internal fluid to flow along the flow hole 3433 to achieve a damping effect, so that the friction ring 345 and the output end of the control motor 341 remain concentric relative to each other. After stopping, the return spring 3436 pushes the piston plate 3434 and the telescopic rod 3435 to reset, making the eccentric outer ring 344 in an eccentric state. When the parturient adopts a special position such as a kneeling and lying position, and the monitoring position is relatively inclined and difficult to fix, start the electric cylinder 15. The electric cylinder 15 pulls the annular probe 12 through the rotating shaft 9, so that the airbag at the pulling position is compressed, so that the bottom of the annular probe 12 also tilts to fit the monitoring position. Gas can be filled into the annular airbag 13 as needed to make the annular airbag 13 expand and increase in volume until the bottom probe firmly contacts the abdomen of the parturient.
