Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary delivery devices, in particular to an auxiliary delivery device capable of automatically adjusting angles and leg postures. Background Art

[0002] Pregnant women will experience a very painful process during childbirth. During this process, they will struggle and lose the strength to position their legs. In order to reduce the pain of pregnant women during childbirth, assisted delivery devices are added to assist childbirth.

[0003] Most existing assistive devices are unable to adjust the leg position of pregnant women during labor. Pregnant women are prone to struggling during labor, causing changes in leg position, which can affect the safety of the newborn. Changes in body position can also prolong labor and increase the risk of childbirth. During labor, most women rely on their own strength, which can greatly deplete their energy in a short period of time. If labor is prolonged or the woman lacks strength, a normal delivery may not be possible, which can easily cause harm to the mother and fetus.

[0004] In addition, pregnant women are very likely to produce a lot of sweat during the struggle. When the sweat evaporates on the forehead, it will take away a lot of heat from the pregnant woman herself, which can easily cause the risk of the head being exposed to the wind, or even cause the pregnant woman to suffer from hypothermia, affecting the safety of delivery. Summary of the Invention

[0005] The object of the present invention is to provide an auxiliary delivery device that automatically adjusts the angle and leg posture to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] An auxiliary delivery device that automatically adjusts the angle and leg posture includes a supporting device, a buffering device, an adjusting device, a clamping device and an expansion cylinder. The supporting device and the buffering device are connected, the buffering device and the adjusting device are connected by pipeline, the adjusting device and the supporting device are connected, the clamping device and the supporting device are connected, the outer frame of the expansion cylinder and the supporting device are tightly connected, and the output end of the expansion cylinder and the clamping device are transmission-connected. The supporting device includes a bed body, and clamping devices are provided on both sides of the bed body. The buffering device includes a head airbag, one side of the head airbag is tightly connected to the bed body, and the adjusting device includes a waist airbag, which is placed in the middle of the bed body, and the head airbag and the waist airbag are connected by pipeline.

[0008] The supporting device is the main installation basis, and other devices are installed through the supporting device. The buffer device provides buffering protection for the pregnant woman's head, and the adjusting device protects the pregnant woman's waist. The clamping device is located on the inner side of the legs to support the legs to prevent the pregnant woman from losing strength during delivery, so that the pregnant woman can get more comfortable support during delivery and reduce the loss of strength during struggle. The power is provided by the expansion cylinder, and the expansion cylinder is connected to the clamping device to drive the clamping device to move, so as to facilitate the adjustment of the pregnant woman's leg posture. The expansion cylinder is installed through the bed body. The head airbag is located on the side of the pregnant woman's head to support the pregnant woman's head and protect the pregnant woman's head from impact during the struggle. The pregnant woman's waist is supported by the waist airbag, and the waist airbag and the head airbag are connected through a pipe. During the posture adjustment process, the pregnant woman adjusts the support angles of the waist and head through gas drainage, so that the pregnant woman can get more comfortable support during delivery.

[0009] Furthermore, the clamping device includes a carrier, and slide rails are respectively provided on both sides of the bed, and the slide rails are arranged in an arc shape. The carrier and the slide rails are slidably connected. The carrier includes a base plate and a rotating plate. A connecting plate is provided between the base plate and the rotating plate. The base plate is transmission-connected to the connecting plate and the rotating plate through the connecting plate. A first arc plate is provided at the lower end of the base plate, and a second arc plate is provided at the lower end of the rotating plate. The slide rails include an inner rail and an outer rail. The base plate is slidably connected to the inner rail through the first arc plate, and the rotating plate is slidably connected to the outer rail through the second arc plate. A first airbag is provided on the outside of the base plate, and a second airbag is provided on the outside of the rotating plate. The first airbag and the second airbag are connected through pipelines.

[0010] The carrier is slidably guided by the slide rail to adjust the leg posture of the pregnant woman. Two groups of carriers are set along the legs. Each group of carriers includes a base plate and a rotating plate. The base plate is located at the lower part of the thigh and supports the thigh through the first airbag. The rotating plate is located at the lower part of the calf and supports the calf through the second airbag. The base plate and the rotating plate are set at an angle to assist the waist airbag and the head airbag to perform multi-point positioning of the human body. The second arc plate is slidably guided by the outer rail, and the first arc plate is slidably guided by the inner rail. The inner rail is located in the inner circle. When the legs are expanded and adjusted by the carrier, the inner circle is rotated in a small arc, and the outer The circle rotates in a large arc. When the pregnant woman struggles, her middle section sinks and both ends are lifted up, squeezing the first airbag and the waist airbag respectively. The first airbag transmits the internal gas to the second airbag through a pipe, causing the second airbag to swell, compensating for the gap between the calf and the second airbag when the calf is lifted, so that the second airbag and the calf are in contact and supported; the waist airbag transmits gas to the head airbag, causing the head airbag to swell, compensating for the gap caused by the lifting of the head, so that the head airbag is in contact and supported on the head, thereby ensuring that during the delivery process, the pregnant woman's legs, waist and head are supported in real time, reducing the physical exertion of the pregnant woman.

[0011] Furthermore, the buffer device also includes a circulating air pump, a temperature control component and a circulating seat. The circulating seat is placed on the upper side of the head airbag, and a soft edge is provided on the lower side of the circulating seat. A guide chamber is provided on the circulating seat, and the soft edge is arranged along the outer edge of the guide chamber. An inlet and an outlet are respectively provided on both sides of the guide chamber. The circulating air pump is placed at the outlet of the guide chamber, and the negative pressure end of the circulating air pump is connected to the outlet of the guide chamber. A detection cavity is provided on the circulating seat, and the temperature control component is placed in the detection cavity. The temperature control component includes an expansion airbag and a heat exchange plate, one end of the heat exchange plate faces the guide chamber, the expansion airbag is placed in the detection cavity, and the end of the heat exchange plate away from the guide chamber is placed in the expansion airbag.

[0012] The circulating air pump is the power source for gas circulation. The circulating seat installs the circulating air pump through the diversion chamber. The air inlet end of the circulating air pump faces the space between the diversion chamber and the pregnant woman's forehead. The relative sealing of the diversion chamber is ensured by the soft edge. The circulating air pump inhales air to reduce the pressure in the diversion chamber, reduce the saturated vapor pressure, vaporize the sweat on the forehead, and reach a gas-liquid equilibrium state. The vaporized sweat is then discharged through the circulating air pump for local microcirculation. Adsorbents such as activated carbon are set at the outlet of the circulating air pump to dehydrate the sweat in the circulating air flow and improve the circulation safety. The temperature control component is placed in the detection cavity, and temperature monitoring is performed through the temperature control component. One end of the heat exchange plate faces the diversion chamber, and the other end is placed in the expansion airbag. The expansion airbag is filled with compressed gas. When the gas flows through the heat exchange plate, heat is exchanged through the heat exchange plate, causing the compressed gas in the expansion airbag to expand. The degree of expansion of the expansion airbag is positively correlated with the gas temperature in the diversion chamber to prevent the temperature from being too low and affecting the thermal insulation performance of the forehead.

[0013] Furthermore, the buffer device also includes an electric heating tube, a control chamber is provided on the circulation seat, the electric heating tube is placed in the control chamber, the control chamber is connected to the inlet of the diversion chamber, the temperature control component also includes a transmission plate and an electrode plate, the electrode plate and the electric heating tube are electrically connected, the expansion airbag and the transmission plate are transmission connected, a transmission groove is provided on the circulation seat, the electrode plate is placed in the transmission groove, the transmission plate and the electrode plate are transmission connected, the electrode plate includes a fixed plate and a sliding plate, the sliding plate is connected to the transmission plate, and the fixed plate is placed on the side of the transmission groove away from the sliding plate.

[0014] The electric heating tube is installed through the control room. The electric heating tube is the heat source for gas heating and is electrically connected to the electrode plate. The electrode plate includes two opposing fixed plates and a sliding plate. The fixed plate is placed in the transmission groove. When the expansion airbag outputs displacement, it drives the sliding plate to move, so that the relative distance between the sliding plate and the fixed plate increases. The fixed plate and the sliding plate are connected in series to the power supply, and the gap between the fixed plate and the sliding plate is broken down to make the circuit conductive. The electrode plate and the electric heating tube are connected in series to form a self-heating circuit. The circulating airflow is heated by electric heat, and the vaporization of sweat on the forehead causes heat absorption. The heat loss of the human body is compensated by mechanical heating. When the circulating airflow is overheated, the output displacement of the expansion airbag increases, the distance between the sliding plate and the fixed plate increases, the electrical conductivity decreases, and the conductive performance decreases, so that the current of the self-heating circuit is reduced and the heat generated by the electric heating tube is reduced, so that the heat generated by the electric heating tube is negatively correlated with the expansion amount of the expansion airbag, preventing the temperature in the diversion room from being too high and automatically regulating the temperature.

[0015] Furthermore, the adjusting device also includes a belt, a traction electric cylinder, a tensioning pulley and a clamping block. A mounting groove is provided on the bed, the traction electric cylinder is placed in the mounting groove, the belt is arranged horizontally along the bed, high-pressure gas is filled in the belt, the output end of the traction electric cylinder and one side of the belt are transmission-connected, the supporting device also includes a pressure-compensating box, the pressure-compensating box and the bed are tightly connected, an adjusting chamber is provided in the pressure-compensating box, the tensioning pulley and the adjusting chamber are rotatably connected, the end of the belt away from the traction electric cylinder is wrapped around the tensioning pulley, a clamping groove is provided on the tensioning pulley, the clamping block and the clamping groove are rotatably connected, a wedge groove is provided on the clamping block, a limiting groove is provided on the pressure-compensating box, the clamping block is intermittently clamped through the wedge groove and the limiting groove, a pre-tightening spring is provided on one side of the clamping block, the pre-tightening spring is tightly connected to the limiting groove away from the side of the clamping block, a reset spring is provided on the outer ring of the shaft end on both sides of the tensioning pulley, the reset spring is tightly connected to the adjusting chamber away from the side of the tensioning pulley.

[0016] After the fetal posture adjustment is completed, the front of the pregnant woman is assisted by the strap to prevent the fetus from moving towards the head during the lying process, which prolongs the delivery process. The strap is tensioned on one side by the traction electric cylinder, and the other end is tensioned by the tensioning wheel in the pressure compensation box. The strap is a strip-shaped air bag, and the bottom end is wrapped around the tensioning wheel. The ends of the strap are placed on the left and right sides of the pregnant woman respectively to limit the upper layer of the pregnant belly on one side. During the delivery process, the strap provides flexible force to assist delivery. The tensioning wheel is rotated and guided by the adjustment chamber, and the block rotates along the slot. The pre-tightening spring provides pre-tightening force, and the reset spring performs preliminary compression so that there is a gap between the block and the limit slot in the initial state. When the middle part of the pregnant woman moves up, The tensioning wheel is driven to rotate by the belt, and the block remains stationary under the action of inertia. The tensioning wheel rotates instantaneously, compressing the preload spring, and causing relative rotation between the block and the tensioning wheel. The block is accommodated in the slot and is transmitted through the slot wall, driving the block to cross the rear section of the limit slot, so that the belt on the tensioning wheel is automatically untied, extending the outer extension of the belt, and loosening the belt to avoid damage to the pregnant woman's middle part during the upward struggle. When the pregnant woman's middle part moves downward, the belt is tightened by the reset spring, and the displacement is output by the traction electric cylinder. When the traction electric cylinder output is in the position, the inertia force is small, so that the block cannot fully enter the slot, and the wedge groove of the block is connected to the limit groove, thereby limiting the position and assisting delivery.

[0017] Furthermore, the adjustment device also includes a stop plate, a pressure relief groove is provided on the tensioning wheel, the pressure relief groove is connected to the belt pipe, the stop plate and the pressure relief groove are slidably connected, the stop plate is placed at the end of the rotation stroke of the clamping block, and a limit block is provided on one side wall of the adjustment chamber;

[0018] Initial state: the stop plate is placed at the outlet of the pressure relief tank;

[0019] During discharge: the outer side of the clamping block is connected to the limit block, the side of the clamping block is connected to the stop plate, and the pressure relief groove is connected to the regulating chamber.

[0020] In the initial state, the stop plate is located at the outlet of the pressure relief groove, the pressure relief groove and the tail end of the strap are connected, the air pressure in the strap is greater than the air pressure at the outlet of the pressure relief groove, and under the action of the pressure difference, the stop plate blocks the mouth of the pressure relief groove. When the middle part of the pregnant woman moves up, the card block completely enters the card slot under the action of inertia, and as the tensioning wheel passes over the limit groove, when the pregnant woman struggles and the middle part offsets a long distance, the instantaneous compression of the gas in the strap increases. After the card block enters the card slot, it is further rotated in the card slot through the limit block and the card block. A protrusion is provided on the upper side of the stop plate, and the card block drives the stop plate to rotate through the protrusion, thereby performing mechanical pressure relief, making the pressure relief groove and the regulating chamber conductive, and the gas in the strap is quickly depressurized through the pressure relief groove.

[0021] Furthermore, the regulating device includes a pressure-stabilizing pump, a compensating chamber is provided on the pressure-compensating tank, the pressure-stabilizing pump is placed in the compensating chamber, and the compensating chamber is communicated with the regulating chamber;

[0022] During pressure replenishment: The pressure on the side of the stop plate closest to the regulating chamber is greater than the pressure in the pressure relief groove. Pressure replenishment is performed using a pressure-stabilizing pump. When the pregnant woman's midsection moves downward, the cinch band loosens, the internal gas pressure decreases, and air is introduced through the pressure-stabilizing pump, making the pressure in the regulating chamber greater than the pressure inside the cinch band. Under the action of the pressure differential, the stop plate moves downward, connecting the regulating chamber and the pressure relief groove, thereby replenishing pressure in the cinch band. This prevents the cinch band from loosening, reducing its one-way limiting performance on the pregnant belly, and prolonging labor.

[0023] As an optimization, the inflatable airbag consists of a large-diameter section and a small-diameter section. The small-diameter section serves as the output end. A bump is provided on the transmission plate near the inflatable airbag. The small-diameter section is connected to the transmission plate through the bump, and the detection cavity is arranged in a stepped manner. The inflatable airbag is designed in two sections, with the heat exchanger placed at the large-diameter end and the small-diameter section serving as the output end. This allows deformation to be concentrated in the small-diameter section, improving detection sensitivity. The detection cavity is stepped to limit the large and small-diameter sections.

[0024] As an optimization, the bed frame is equipped with accommodating grooves on both sides, in which the expansion cylinder is placed. The output end of the expansion cylinder is connected to the second curved plate in a transmission manner. The expansion cylinder is installed in the accommodating groove, making the expansion cylinder hidden. The expansion cylinder and the second curved plate are driven by the expansion cylinder, which drives the rotating plate to rotate. The rotating plate drives the base plate through the connecting plate, thereby adjusting the leg posture.

[0025] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: when a pregnant woman is struggling, when her middle part sinks and both ends are lifted, the first airbag and the waist airbag are squeezed respectively, and the first airbag transports the internal gas to the second airbag through the pipeline, causing the second airbag to swell, compensating for the gap between the second airbag when the calf is lifted, so that the second airbag and the calf are in contact and supported; the waist airbag transports gas to the head airbag, causing the head airbag to swell, compensating for the gap caused by the lifting of the head, so that the head airbag is in contact and supported on the head, thereby ensuring that the pregnant woman's legs, waist and head are supported in real time during the delivery process, reducing the physical exertion of the pregnant woman; the circulating air pump is used to inhale air, so that the pressure in the diversion chamber is reduced, the saturated vapor pressure is reduced, the sweat on the forehead is vaporized, and a gas-liquid equilibrium state is reached, and the vaporized sweat is discharged through the circulating air pump for local microcirculation; the electrode plate and the electric heating tube are connected in series to form a self-heating electric heating tube. The circulating airflow is heated by electric heating, and the evaporation of sweat on the forehead causes heat absorption. The heat loss of the human body is compensated by mechanical heating. When the circulating airflow is overheated, the output displacement of the expansion airbag increases, the distance between the sliding plate and the fixed plate increases, the electrical conductivity decreases, and the conductive performance decreases, which reduces the current of the self-heating circuit and the heat generated by the electric heating tube. As a result, the heat generated by the electric heating tube and the expansion amount of the expansion airbag are negatively correlated, preventing the temperature in the diversion room from being too high and automatically regulating the temperature; when the middle part of the pregnant woman moves upward, the tensioning wheel is driven to rotate by the belt, and the block remains stationary under the action of inertia. The tensioning wheel rotates instantaneously, causing the preload spring to be compressed, and the block and the tensioning wheel rotate relative to each other. The block is accommodated in the slot and is driven by the slot wall to cross the rear section of the limit slot, so that the belt on the tensioning wheel is automatically untied, extending the outer extension of the belt, and loosening the belt to avoid injury during the upward struggle of the pregnant woman's middle part.

[0039] The support device 1 is the main installation basis, and other devices are installed through the support device 1. The buffer device 2 provides buffering protection for the pregnant woman's head, and the adjusting device 3 protects the pregnant woman's waist. The clamping device 4 is located on the inner side of the legs to support the legs, preventing the pregnant woman from losing strength during delivery, so that the pregnant woman can get a more comfortable support strength during delivery and reduce the strength lost during struggling. The expansion cylinder 5 provides power, and the expansion cylinder 5 is connected to the clamping device 4 to drive the clamping device 4 to move, so that the pregnant woman can adjust the leg posture. The expansion cylinder 5 is installed through the bed body 11. The head airbag 21 is located on the side of the pregnant woman's head to support the pregnant woman's head and protect the pregnant woman's head from impact during struggling. The pregnant woman's waist is supported by the waist airbag 36. The waist airbag 36 and the head airbag 21 are connected by a pipe. During the posture adjustment process, the pregnant woman can adjust the support angle of the waist and head through gas drainage, so that the pregnant woman can get a more comfortable support strength during delivery.

[0040] like Figures 1 to 3 As shown, the clamping device 4 includes a carrier 41, and slide rails 112 are respectively provided on both sides of the bed 11. The slide rails 112 are arranged in an arc shape, and the carrier 41 and the slide rails 112 are slidably connected. The carrier 41 includes a base plate 411 and a rotating plate 412. A connecting plate is provided between the base plate 411 and the rotating plate 412.

A first airbag 42 is provided on the outside of the base plate 411, and a second airbag 43 is provided on the outside of the rotating plate 412. The first airbag 42 and the second airbag 43 are connected by pipes.

[0041] The carrier 41 is slidably guided by the slide rail 112, so as to adjust the leg posture of the pregnant woman. Two groups of carriers are set along the legs through the carrier 41, and each group of carriers includes a base plate 411 and a rotating plate 412. The base plate 411 is located at the lower part of the thigh and supports the thigh through the first airbag 42. The rotating plate 412 is located at the lower part of the calf and supports the calf through the second airbag 43. The base plate 411 and the rotating plate 412 are set at an angle to assist the waist airbag 36 and the head airbag 21 to perform multi-point positioning of the human body. The second arc plate 414 is slidably guided by the outer rail 1122, and the first arc plate 413 is slidably guided by the inner rail 1121. The inner rail 1121 is located at the inner circle. When the lower leg is expanded and adjusted, the inner circle rotates in a small arc and the outer circle rotates in a large arc. When the pregnant woman is struggling, the middle section sinks and the two ends are lifted, squeezing the first airbag 42 and the waist airbag respectively. The first airbag 42 transports the internal gas to the second airbag 43 through the pipe, causing the second airbag 43 to swell, compensating for the gap between the calf and the second airbag 43 when the calf is lifted, so that the second airbag 43 and the calf are in contact and supported; the waist airbag 36 transports gas to the head airbag 21, causing the head airbag to swell, compensating for the gap caused by the lifting of the head, so that the head airbag is in contact and supported on the head, thereby ensuring that during the delivery process, the legs, waist and head of the pregnant woman are supported in real time, reducing the physical exertion of the pregnant woman.

[0042] like Figures 2 to 4 As shown, the buffer device 2 also includes a circulating air pump 22, a temperature control component 23 and a circulating seat 24. The circulating seat 24 is placed on the upper side of the head airbag 21. A soft edge is provided on the lower side of the circulating seat 24. A guide chamber 242 is provided on the circulating seat 24. The soft edge is arranged along the outer edge of the guide chamber 242. An inlet and an outlet are respectively provided on both sides of the guide chamber 242. The circulating air pump 22 is placed at the outlet of the guide chamber 242. The negative pressure end of the circulating air pump 22 is connected to the outlet of the guide chamber 242. A detection chamber 241 is provided on the circulating seat 24. The temperature control component 23 is placed in the detection chamber 241. The temperature control component 23 includes an expansion airbag 231 and a heat exchange plate 233.

[0043] The circulating air pump 22 is the power source for gas circulation. The circulating seat 24 is used to install the circulating air pump 22 through the guide chamber 242. The air inlet end of the circulating air pump 22 faces the space between the guide chamber 242 and the forehead of the pregnant woman. The relative sealing of the guide chamber 242 is ensured by the soft edge. The circulating air pump 22 inhales air to reduce the pressure in the guide chamber 242, the saturated vapor pressure is reduced, and the sweat on the forehead is vaporized to reach a gas-liquid equilibrium state. The vaporized sweat is then discharged through the circulating air pump 22 for local microcirculation. Activated carbon and other adsorbents are set at the outlet of the circulating air pump 22 to regulate the circulation. The sweat in the circulating air flow is dehydrated to improve the circulation safety. The temperature control component 23 is placed in the detection cavity 241, and the temperature is monitored through the temperature control component 23. One end of the heat exchange plate 233 faces the guide chamber 242, and the other end is placed in the expansion airbag 231. The expansion airbag 231 is filled with compressed gas. When the gas flows through the heat exchange plate 233, heat is exchanged through the heat exchange plate, causing the compressed gas in the expansion airbag 231 to expand. The degree of expansion of the expansion airbag 231 is positively correlated with the gas temperature in the guide chamber 242, preventing the temperature from being too low and affecting the heat preservation performance of the forehead.

[0044] like Figure 4 As shown, the buffer device 2 also includes an electric heating tube 25, a control chamber 244 is provided on the circulation seat 24, the electric heating tube 25 is placed in the control chamber 244, the control chamber 244 is connected to the inlet of the guide chamber 242, the temperature control component 23 also includes a transmission plate 232 and an electrode plate 234, the electrode plate 234 is electrically connected to the electric heating tube 25, the expansion airbag 231 is transmission-connected to the transmission plate 232, a transmission groove 243 is provided on the circulation seat 24, the electrode plate 234 is placed in the transmission groove 243, the transmission plate 232 is transmission-connected to the electrode plate 234, the electrode plate 234 includes a fixed plate and a sliding plate, the sliding plate is connected to the transmission plate 232, and the fixed plate is placed on the side of the transmission groove 243 away from the sliding plate.

[0045] The electric heating tube 25 is installed through the control room 244. The electric heating tube 25 is a heat source for gas heating and is electrically connected to the electrode plate 234. The electrode plate 234 includes two opposing fixed plates and a sliding plate. The fixed plate is placed in the transmission groove 243. When the expansion airbag 231 outputs displacement, it drives the sliding plate to move, so that the relative distance between the sliding plate and the fixed plate increases. The fixed plate and the sliding plate are connected in series to the power supply, breaking through the gap between the fixed plate and the sliding plate to make the circuit conductive. The electrode plate 234 and the electric heating tube 25 are connected in series to form a self-heating device. The thermal circuit heats the circulating airflow through electric heating, and the vaporization of sweat on the forehead causes heat absorption. The heat loss of the human body is compensated by mechanical heating. When the circulating airflow is overheated, the output displacement of the expansion airbag 231 increases, the distance between the sliding plate and the fixed plate increases, the electrical conductivity decreases, and the conductive performance decreases, which reduces the current of the self-heating circuit and the heat generated by the electric heating tube 25. As a result, the heat generated by the electric heating tube 25 is negatively correlated with the expansion amount of the expansion airbag 231, preventing the temperature in the guide chamber 242 from being too high and automatically regulating the temperature.

[0046] like Figure 2 、 Figures 5 to 7 As shown, the adjusting device 3 also includes a belt 31, a traction electric cylinder 32, a tensioning wheel 33 and a clamping block 34. A mounting groove 111 is provided on the bed 11, and the traction electric cylinder 32 is placed in the mounting groove 111. The belt 31 is arranged horizontally along the bed 11. The belt 31 is filled with high-pressure gas. The output end of the traction electric cylinder 32 is connected to one side of the belt 31 by transmission. The supporting device 1 also includes a pressure-compensating box 12. The pressure-compensating box 12 is fastened to the bed 11. An adjusting chamber 121 is provided in the pressure-compensating box 12. The tensioning wheel 33 is rotatably connected to the adjusting chamber 121. The belt 31 is far away One end of the traction electric cylinder 32 is wound around the tensioning wheel 33, and a slot 331 is provided on the tensioning wheel 33. The clamping block 34 is rotatably connected to the slot 331. A wedge groove is provided on the clamping block 34, and a limiting groove 123 is provided on the pressure compensation box 12. The clamping block 34 is intermittently clamped through the wedge groove and the limiting groove 123. A pre-tightening spring 35 is provided on one side of the clamping block 34. The pre-tightening spring 35 is fastened to the limiting groove 123 away from the side of the clamping block 34. The outer rings of the shaft ends on both sides of the tensioning wheel 33 are provided with return springs. The return spring is fastened to the adjustment chamber 121 away from the side of the tensioning wheel 33.

[0047] After the fetal posture adjustment is completed, the front of the pregnant woman is assisted supported by the strap 31 to prevent the fetal position from moving towards the head during the pregnant woman's lying process, thereby prolonging the delivery process. The strap 31 is tensioned on one side by the traction electric cylinder 32, and the other end is tensioned by the tensioning wheel 33 in the pressure compensation box 12. The strap 31 is a strip-shaped air bag, and the bottom end is wrapped around the tensioning wheel 33. The ends of the strap 31 are placed on the left and right sides of the pregnant woman respectively to limit the upper layer of the pregnant belly on one side. During delivery, the strap 31 provides flexible force to assist delivery. The tensioning wheel 33 is rotated and guided by the adjustment chamber 121, and the block 34 rotates along the slot 331. The pre-tightening force is provided by the pre-tightening spring 35, and the initial compression is performed by the return spring so that there is a gap between the block 34 and the limit slot 13 in the initial state. When the middle part of the pregnant woman moves up, the strap The clamping block 34 is held in the clamping groove 331 and the clamping block 34 is driven to move past the rear end of the limit groove 123, so that the strap 31 on the tension wheel 33 is automatically untied, and the outer extension of the strap 31 is extended to loosen the strap, thereby avoiding damage to the pregnant woman's middle part during the upward struggle. When the pregnant woman's middle part moves downward, the strap is tightened by the reset spring, and the displacement is output by the traction electric cylinder 32. When the traction electric cylinder 32 output is in the position, the inertia force is small, so that the clamping block 34 cannot fully enter the clamping groove, and the wedge groove of the clamping block 34 is clamped in the limit groove 123, thereby limiting the position and assisting delivery.

[0048] like Figures 6 to 8As shown, the adjustment device 3 also includes a stop plate 38, a pressure relief groove 332 is provided on the tensioning wheel 33, the pressure relief groove 332 is connected to the pipe of the belt 31, the stop plate 38 and the pressure relief groove 332 are slidably connected, the stop plate 38 is placed at the end of the rotation stroke of the clamping block 34, and a limit block is provided on one side wall of the adjustment chamber 121;

[0049] Initial state: the cut-off plate 38 is placed at the outlet of the pressure relief groove 332;

[0050] During flow discharge: the outer side of the clamping block 34 is in transmission connection with the limit block, the side of the clamping block 34 is in transmission connection with the cut-off plate 38 , and the pressure relief groove 332 is in communication with the regulating chamber 121 .

[0051] After the pressure relief valve 331 is lifted up, the pressure relief valve 331 is lifted up and the pressure relief valve 332 is lifted up, so that the pressure relief valve 331 is lifted up and the pressure relief valve 332 is lifted up.

[0052] like Figure 2 、 Figure 6 As shown, the regulating device 3 includes a pressure-stabilizing pump 39, a compensation chamber 122 is provided on the pressure-stabilizing tank 12, the pressure-stabilizing pump 39 is placed in the compensation chamber 122, and the compensation chamber 122 is communicated with the regulating chamber 121;

[0053] During pressure replenishment: The pressure on the side of the stop plate 38 closest to the regulating chamber 121 is greater than the pressure in the pressure relief groove 332. Pressure replenishment is provided by the pressure-stabilizing pump 39. When the pregnant woman's midsection moves downward, the cinch 31 relaxes, the internal gas pressure decreases, and air is introduced through the pressure-stabilizing pump 39, causing the pressure in the regulating chamber 121 to exceed the pressure in the cinch 31. Under the action of the pressure differential, the stop plate 38 moves downward, connecting the regulating chamber 121 and the pressure relief groove 332, thereby replenishing the pressure in the cinch 31 and preventing the cinch 31 from relaxing and reducing its one-way retaining function on the pregnant belly, thereby prolonging labor.

[0054] As an optimization, the inflatable airbag 22 comprises a large-diameter section and a small-diameter section, with the small-diameter section serving as the output end. A bump is provided on the transmission plate 232 near the inflatable airbag 22, connecting the small-diameter section to the transmission plate 232 via the bump. The detection cavity 341 is arranged in a stepped manner. The inflatable airbag 22 is designed in two sections, with the heat exchange fin 233 positioned at the large-diameter end and the small-diameter section serving as the output end. This allows deformation to be concentrated in the small-diameter section, improving detection sensitivity. The detection cavity 341 is stepped to limit the large and small-diameter sections.

[0055] As an optimization, accommodating grooves are provided on both sides of the bed 11, into which the expansion cylinder 5 is placed, and the output end of the expansion cylinder 5 is connected by transmission to the second curved plate 414. The expansion cylinder 5 is installed in the accommodating groove, so that the expansion cylinder 5 is hidden. Transmission is generated by the expansion cylinder 5 and the second curved plate 414, thereby causing the second curved plate 414 to rotate the rotating plate 412. The rotating plate 412 is driven by the connecting plate, which drives the base plate 411 to rotate, thereby adjusting the leg posture.

[0056] The working principle of the present invention is as follows: when a pregnant woman is struggling, her middle part sinks and both ends are lifted, the first airbag 42 and the waist airbag are squeezed respectively, and the first airbag 42 transports the internal gas to the second airbag 43 through the pipeline, causing the second airbag 43 to swell, compensating for the gap between the second airbag 43 when the calf is lifted, so that the second airbag 43 and the calf are in contact and supported; the waist airbag 36 transports gas to the head airbag 21, causing the head airbag to swell, compensating for the gap caused by the lifting of the head, so that the head airbag is in contact and supported on the head, thereby ensuring that the legs, waist and head of the pregnant woman are supported in real time during the delivery process, reducing the physical exertion of the pregnant woman; the circulating air pump 22 inhales air, so that the pressure in the guide chamber 242 is reduced, the saturated vapor pressure is reduced, the sweat on the forehead is vaporized, and a gas-liquid equilibrium state is reached, and then the vaporized sweat is discharged through the circulating air pump 22 for local microcirculation; the electrode plate 234 and the electric heating tube 25 are connected in series to form a self-heating circuit, which heats the circulating airflow by electric heating. Heat increase, the evaporation of sweat on the forehead causes heat absorption, and the heat loss of the human body is compensated by mechanical heat increase. When the circulating airflow is overheated, the output displacement of the expansion airbag 231 increases, the distance between the sliding plate and the fixed plate increases, the conductivity decreases, the conductive performance decreases, the current of the self-heating circuit decreases, and the heat generated by the electric heating tube 25 decreases, so that the heat generated by the electric heating tube 25 and the expansion amount of the expansion airbag 231 are negatively correlated, preventing the temperature in the guide chamber 242 from being too high, and automatically regulating the temperature; when the middle part of the pregnant woman moves up, through The strap 31 drives the tensioning wheel 33 to rotate, and the block 34 remains stationary under the action of inertia. The tensioning wheel 33 rotates instantaneously, compressing the preload spring 35. The block 34 and the tensioning wheel 33 rotate relative to each other, and the block 34 is accommodated in the slot 331. The block 34 is driven through the wall of the slot to cross the rear section of the limit slot 123, so that the strap 31 on the tensioning wheel 33 is automatically untied, extending the outer extension of the strap 31, loosening the strap, and avoiding damage to the pregnant woman's middle part during the upward struggle.
