[0019] like Figures 1-8 shown.

[0020] In some embodiments, the adjustable leg support mechanism 3 may include a position adjustment component and an angle adjustment locking component to support the legs of pregnant women of different heights.

[0021] Among them, the position adjustment component includes a sliding shaft 301, which is slidably connected to the recliner component 2; a rotating support plate 302, which is rotatably connected to the sliding shaft 301; a driving screw 303, which is rotatably connected to the recliner component 2 and threadedly connected to the sliding shaft 301, for adjusting the position of the sliding shaft 301; a sliding groove 304, which is opened on the sliding shaft 301; a support block 305, which is slidably connected in the sliding groove 304, for supporting the legs of the pregnant woman; a telescopic spring 306, one end of which is fixedly connected to the support block 305 and the other end is fixedly connected to the sliding shaft 301, for driving the support block 305 to reset; a strap 307, which is installed at the top of the support block 305, for fixing the legs of the pregnant woman on the support block 305.

[0022] In this embodiment, the position of the rotating support plate 302 is first adjusted according to the height of the pregnant woman. The manually rotating drive screw 303 can drive the sliding shaft 301 to move, and then the rotating support plate 302 rotatably connected to the sliding shaft 301 is moved, so that the support block 305 installed on the rotating support plate 302 is moved to the appropriate position of the pregnant woman's legs, and the pregnant woman's legs are placed on the support block 305 for support.

[0023] It should be noted that the threaded connection between the drive screw 303 and the sliding shaft 301 allows for fine adjustment of the position of the sliding shaft 301 by rotating the drive screw, thereby driving the synchronous displacement of the rotating support plate 302 and the support block 305. This design allows the support block 305 to be precisely adjusted to the appropriate leg support position based on individual differences such as the pregnant woman's height and leg length, ensuring that pregnant women of all shapes and sizes can receive a tailored support experience, thereby enhancing universal use.

[0024] Among them, the angle adjustment locking assembly includes a docking tooth 308, which is fixedly connected to one end of the rotating support plate 302 close to the sliding shaft 301; a lifting rack 309, which is meshed and connected to the docking tooth 308 and is used to lock the angle of the rotating support plate 302; a control rod 310, which passes through and slides to connect the recliner assembly 2 and is fixedly installed on the lifting rack 309; a reset spring 311, one end of which is fixedly connected to the recliner assembly 2 and the other end is fixedly connected to the control rod 310, which is used to drive the lifting rack 309 to reset.

[0025] In this embodiment, the pregnant woman can adjust the angle of the rotating support plate 302 by herself through the force of her legs according to her own comfort. The pregnant woman can lie on the recliner assembly 2 and manually pull the lifting rack 309 upward through the control rod 310 to separate the lifting rack 309 from the docking tooth 308. At this time, the rotating support plate 302 can rotate freely. After the pregnant woman adjusts the angle of the rotating support plate 302, she releases the control rod 310. The control rod 310 is reset under the action of the reset spring 311, and the lifting rack 309 re-engages the docking tooth 308 to lock the angle of the rotating support plate 302.

[0026] It should be noted that the meshing cooperation between the docking teeth 308 and the lifting rack 309 provides a multi-level locking basis for the angle adjustment of the rotating support plate 302. Pregnant women can freely adjust the angle of the rotating support plate 302 by exerting force on their legs according to their own comfort needs to meet the support needs in different postures, such as slightly bending the legs, laying them flat or slightly lifting them, etc., further improving the adaptability of the device to individual differences.

[0027] In some embodiments, the waist support adjustment structure 4 may include an air intake component, a lifting adjustment component, and an exhaust component to adjust the height and position of the waist of a pregnant woman during childbirth.

[0028] The lifting and adjusting assembly includes a supporting airbag 401, which is installed on the reclining chair assembly 2; a limiting baffle 402, which is fixedly arranged on both sides of the supporting airbag 401 and is used to limit the position of the limiting baffle 402; a scissor-type lifting frame 403, which is symmetrically arranged on the reclining chair assembly 2; and a cushion 404, which is fixedly installed on the top of the scissor-type lifting frame 403. In this embodiment, the support airbag 401 expands after intake of air, thereby moving the position of the cushion 404 upward. The scissor-type lifting frame 403 connected to the cushion 404 can ensure that the cushion 404 rises upward in the vertical direction.

[0029] Among them, the air intake component includes an air intake pipe 405, which passes through and is fixedly connected to the support airbag 401; a one-way valve 406, which is arranged at the connection between the air intake pipe 405 and the support airbag 401; a fixed cover 408, which is arranged on the recliner component 2; an input airbag 409, which is installed inside the fixed cover 408 and is used to inject air into the support airbag 401; a drive rod 410, which passes through and is slidably connected to the fixed cover 408 and is used to squeeze the input airbag 409.

[0030] Among them, the exhaust component includes an outlet pipe 407, which passes through and is fixedly connected to the support airbag 401 and is used to discharge the gas inside the support airbag 401; an exhaust valve 411 is arranged at the connection position between the outlet pipe 407 and the support airbag 401.

[0031] In this embodiment, the pregnant woman can squeeze the input airbag 409 inside the fixed cover 408 through the driving rod 410 according to her own needs. The input airbag 409 injects gas into the interior of the support airbag 401 to expand the support airbag 401. The expanded support airbag 401 lifts the pregnant woman's waist through the cushion 404, thereby making it easier for the pregnant woman to exert force. After the end, the caregiver can open the exhaust valve 411 to discharge the gas in the support airbag 401 and restore the cushion 404.

[0032] It should be noted that the support airbag 401 expands upon intake, pushing the cushion 404 upward. This, combined with the guiding action of the scissor-type lift frame 403, ensures the cushion 404 rises steadily in the vertical direction, enabling precise adjustment of the lumbar support height. Pregnant women can flexibly adjust the height of their lumbar support by controlling the amount of air intake, based on their specific labor demands, to find the optimal position for exerting force, enhancing comfort and convenience during labor.

[0033] In some embodiments, the recliner assembly 2 may include a reclining board 201 for supporting a pregnant woman; an inclined back panel 202 installed on the reclining board 201 for supporting the back of the pregnant woman; and an inclined headrest 203 installed at one end of the inclined back panel 202 away from the reclining board 201 for supporting the head of the pregnant woman.

[0034] In this embodiment, the lying board 201 serves as the basic bearing component, which can provide stable support for the pregnant woman's buttocks and legs and disperse the pressure from the lower body; the inclined backboard 202 is specially adapted to the back curve, and can provide fitting support according to the shape of the pregnant woman's back, relieving the tension of the back muscles during pregnancy; the inclined headrest 203 accurately supports the head, prevents the neck from being suspended or excessively bent, and reduces the pressure on the cervical spine. The three have clear division of labor, so that all parts of the body can get comfortable support.

[0035] It should be noted that the inclined back plate 202 and the lying plate 201 , and the inclined headrest 203 and the inclined back plate 202 may be connected in a rotatable or detachable manner.

[0036] In some embodiments, a tray can be provided on the support base 1. The tray is provided below the tail of the lying board 201 and can be used to receive secretions produced by pregnant women during childbirth. The tray is made of stainless steel and can be used to place sterile risks and instruments when suturing the perineum after delivery, so that midwives can sew more quickly and avoid walking back and forth to get instruments.

[0037] The reclining board 201 in the reclining chair assembly 2 provides basic support for the pregnant woman's buttocks and legs, the inclined backboard 202 supports the back, and the inclined headrest 203 holds the head. The rotatable connection between the inclined backboard 202 and the reclining board 201, and the inclined headrest 203 and the inclined backboard 202 can adjust the back and head angles according to the needs of the pregnant woman to form a preliminary comfortable support posture; if a detachable connection is used, the components can also be disassembled according to the needs of the scene to enhance the flexibility of use. The position adjustment component of the adjustable leg support mechanism 3 drives the sliding shaft 301 to slide along the reclining chair assembly 2 by manually rotating the drive screw 303, so that the rotating support plate 302 and the support block 305 move to the leg support position suitable for the height of the pregnant woman. The support block 305 is slidably connected to the sliding shaft 301 through the sliding groove 304, and can be elastically expanded and contracted with the leg pressure in conjunction with the telescopic spring 306 to achieve flexible support. The strap 307 fixes the leg on the support block 305 to prevent sliding.

[0038] In the angle adjustment locking assembly, the pregnant woman pulls the control rod 310 to separate the lifting rack 309 from the docking tooth 308, and adjusts the angle of the rotating support plate 302 by exerting force with her legs. After releasing the control rod 310, the return spring 311 drives the lifting rack 309 to return to the engaged docking tooth 308, locking the angle to meet the requirements of different leg postures. In the lumbar support adjustment structure 4, the pregnant woman squeezes the input airbag 409 in the fixed cover 408 through the driving rod 410, and the gas is injected into the support airbag 401 through the air inlet pipe 405 and the one-way valve 406, causing the support airbag 401 to expand.

[0039] The support airbag 401 pushes the cushion 404 to rise, and the symmetrically arranged scissor-type lifting frame 403 ensures that the cushion 404 moves stably in the vertical direction, realizing precise adjustment of the waist support height, which is convenient for pregnant women to exert force. After the delivery, the caregiver opens the exhaust valve 411, and the gas in the support airbag 401 is discharged through the exhaust pipe 407, the cushion 404 is reset, and the limit baffle 402 limits the lateral displacement of the support airbag 401 to ensure stable support. The above is the overall workflow of the present invention. Just repeat this step when you use it next time. The actual operation process is very simple and easy.
