[0001] The invention relates to the technical field of auxiliary support for childbirth, in particular to a self-stabilizing leg support device for pregnancy and childbirth. Background Art

[0002] During pregnancy and childbirth, in order to help the mother's pelvic opening expand and reduce the pressure on the perineum, thereby providing more space for the fetus to pass through and preventing perineal tearing, and to enable doctors and midwives to better observe the perineum area and more accurately guide the delivery process, it is necessary to lift the pregnant woman's legs so that she can take a specific posture on the delivery bed to facilitate the fetus to pass through the birth canal smoothly. In this process, the leg support auxiliary device plays an important role.

[0003] At present, delivery beds on the market usually have basic leg support and adjustment functions, but these functions often require manual adjustment or have only limited automated functions. Common delivery bed designs usually include the following parts: a support table for supporting the body of the pregnant woman, a carrier frame for supporting the legs of the pregnant woman, and adjustment buttons for manually or electrically adjusting the angles of the support table and the carrier frame. However, when lifting the legs of the pregnant woman, this type of delivery bed cannot quickly and adaptively adjust the leg posture freely according to the pregnant woman's own comfort needs through the adjustment button adjustment method.

[0004] To this end, the present invention provides a self-stabilizing leg support device for pregnancy and childbirth. Summary of the invention

The motor 107 is electrically connected, and the output shaft of the motor 107 is fixedly connected to the adjacent rotating frame 106. The bottom side of the rotating frame 108 is fixedly connected with the limit teeth 109. The top of the rotating frame 106 is rotatably connected to the supporting frame 110. The supporting frame 110 is used to support the legs of the pregnant woman. The supporting surface of the supporting frame 110 is set to an arc shape. The upper part of the rotating frame 106 is fixedly connected to the first fixed block 111, and the lower part of the supporting frame 110 is fixedly connected to the first full gear 112. The first fixed block 111 is rotatably connected to the rotating block 113 symmetrically distributed along the front and back of the first fixed block 111, and the rotating block 113 is used to rotate and clamp the adjacent first full gear 112.

[0033] like Figures 5 and 6As shown, it also includes a cylinder 201, which is fixedly connected to the base 101, and the rising button 103 and the descending button 104 are electrically connected to the cylinder 201 through the control module. The telescopic rod of the cylinder 201 is fixedly connected with a limit plate 202 for limiting the limit tooth 109, and the end surface of the limit plate 202 close to the limit tooth 109 is provided with two circles of evenly distributed grooves, wherein the circle of grooves on the left side is consistent with the limit tooth 109 on the left, and the circle of grooves on the right side is consistent with the limit tooth 109 on the right, and the front and rear sides of the limit plate 202 are fixedly connected with cylinder pistons 203 symmetrically distributed along the limit plate 202, and the cylinder part of the cylinder piston 203 is fixedly connected to the fixed frame 105.

[0034] like Figures 7 and 8 As shown, it also includes a connecting cylinder 301 corresponding to the rotating frame 106, the connecting cylinder 301 is fixedly connected to the corresponding rotating frame 106, a hose 302 is connected between the connecting cylinder 301 and the cylinder part of the adjacent cylinder piston 203, a piston cylinder 303 is fixedly connected to the front part of the rotating frame 106, the piston cylinder 303 and the adjacent connecting cylinder 301 are connected through a pipeline, the piston cylinder 303 is slidably connected to the piston frame 304 in the up and down directions, the piston frame 304 is movably connected to the adjacent rotating block 113 through a movable groove, and is used to push the rotating block 113 to clamp the first full gear 112.

[0035] When a pregnant woman is giving birth, she half lies on the sliding support platform 102 with her feet placed on the support frame 110. Then, the pregnant woman adjusts the posture of her legs according to her own comfort needs. During the adjustment process, under the force applied by the legs, the support frame 110 adaptively rotates around the rotating frame 106 to adjust a comfortable calf bending angle, and the rotating frame 108 rotates around the fixed frame 105 to adjust a comfortable leg opening angle. Then, the rising button 103 is pressed downward. The rising button 103 controls the motor 107 through the control module to drive the rotating frame 106 to rotate upward, thereby driving the support frame 110, the first fixed block 111, the first full gear 112 and the rotating block 113 to rotate upward synchronously to adjust a comfortable thigh lifting angle.

[0036] After adjustment, release the rising button 103. The rising button 103 controls the motor 107 to shut down through the control module, so that the rotating frame 106 cannot rotate, and controls the telescopic rod of the cylinder 201 to extend, thereby driving the limit plate 202 to move upward to jam the limit tooth 109, so that the rotating frame 108 cannot rotate. The cylinder piston 203 plays a role in stabilizing and guiding the movement of the limit plate 202. At the same time, the cylinder piston 203 injects gas into the connecting cylinder 301 through the hose 302, and then enters the piston cylinder 303 through the pipeline. The air pressure in the piston cylinder 303 pushes the piston frame 304 to move upward, thereby pushing the rotating block 113 to jam the first full gear 112, so that the carrier 110 cannot rotate.

[0037] After delivery, the descending button 104 is pressed downward first, and the control module controls the motor 107 to drive the rotating frame 106 to rotate downward, thereby driving the supporting frame 110, the first fixed block 111, the first full gear 112 and the rotating block 113 to rotate downward synchronously, and the legs of the pregnant woman are laid flat, and then the ascending button 103 is released. The ascending button 103 controls the motor 107 to shut down through the control module, and controls the telescopic rod of the cylinder 201 to shorten, thereby driving the limit plate 202 to move downward, so that the limit plate 202 no longer blocks the limit tooth 109, so that the rotating frame 108 can rotate. At the same time, the gas in the piston cylinder 303 is drawn back into the cylinder piston 203 through the connecting cylinder 301 and the hose 302. Under the action of negative pressure, the piston frame 304 moves downward, thereby pulling the rotating block 113 to release the first full gear 112, so that the supporting frame 110 can rotate.

[0038] In summary, in the present invention, the support frame 110 can rotate freely around the rotating frame 106, and the rotating frame 108 can rotate freely around the fixed frame 105. By pressing the rising button 103, the rotating frame 106 is driven to rotate freely around the rotating frame 106. In this way, pregnant women can freely adjust the posture of their legs according to their own comfort needs, and the posture will be automatically and fully fixed after the adjustment, assisting pregnant women to give birth in the most comfortable posture.

[0039] like Figures 9 and 10 As shown, it also includes a connecting sleeve 401, which is fixedly connected to the output shaft of the motor 107 on the left side. The right end of the connecting sleeve 401 is fixedly connected to a universal joint 402, and the universal joint 402 bends when the rotating frame 108 is rotated and adjusted. The right end of the universal joint 402 is fixedly connected to a rotating shaft 403, and the right end of the rotating shaft 403 is fixedly connected to a second full gear 404. The bottom of the sliding support platform 102 is fixedly connected to a rack 405, and the rack 405 is meshed with the second full gear 404.

[0040] When the motor 107 drives the rotating frame 106 to rotate upward, the lower body of the pregnant woman gradually approaches the upper body, and the angle between the lower body and the upper body gradually decreases, which makes the pregnant woman feel more uncomfortable in the waist and abdomen. In order to avoid this situation, when lifting the legs, the upper body is moved back a distance to increase the angle between the lower body and the upper body. The specific operation is as follows: The motor 107 drives the rotating frame 106 and the connecting sleeve 401 to rotate in the same direction, and the connecting sleeve 401 drives the rotating shaft 403 to rotate in the same direction through the universal joint 402, thereby driving the second full gear 404 to rotate in the same direction. When the legs are lifted, the second full gear 404 drives the rack 405 to move backward, and the rack 405 drives the sliding support platform 102 to slide backward along the base 101; when the legs are laid flat, the second full gear 404 drives the rack 405 to move forward, and the rack 405 drives the sliding support platform 102 to slide forward and reset along the base 101. In this way, when the legs are lifted, the upper body can automatically move backward to increase the angle between the lower body and the upper body, thereby improving the comfort of the pregnant woman.

[0041] like Fig.11 As shown, it also includes a second fixing block 501 corresponding to the support frame 110, the second fixing block 501 is fixedly connected to the front of the corresponding support frame 110, the second fixing block 501 is slidably connected to the pedal 502 along the front and rear directions, and the bottom of the second fixing block 501 is threadedly connected to a knob 503 for fixing the pedal 502.

[0042] By loosening the knob 503, moving the pedal 502 forward and backward to adjust the position, and then tightening the knob 503 to fix the pedal 502, the soles of the pregnant woman's feet are limited by the pedal 502, so that the legs can remain stable during delivery and avoid movement of the legs during the process of exerting force. In addition, by fixing the position of the soles of the feet, it can be ensured that the mother can better concentrate her strength when exerting force, which helps the fetus to pass through the birth canal smoothly.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
