[0013] 1. During use, the medical staff places the placement board on the bed, and the parturient can sit on the anti-slip grooves on the placement board with her back against the seat back. At this time, the drive motor can be started, and the output end of the drive motor rotates to drive the screw to rotate counterclockwise. The second hinge block is restricted by the limit groove so that the second hinge block can only move along the length direction of the screw. At this time, the second hinge block will move in the direction of the drive motor, and the movement of the second hinge block will drive the lower end of the support plate to move together, and the seat back and the support plate will be in a state of opposite inclination. At this time, an angle appears between the support plate and the seat back, so a stable triangular shape is formed between the placement board, the seat back and the support plate, thereby ensuring that the seat back has support during the backward tilting process, thereby ensuring the stability of the parturient during the backward leaning process, and improving the safety of the parturient during delivery;

[0014] 2. During use, when the parturient leans back, her buttocks will contact the inclined surfaces of the two rubber shields, and the blocking blocks inside the rubber shields provide a certain support force for the parturient's buttocks, ensuring that the back of the pregnant woman will not slide down during the leaning back process, thereby improving the comfort of the parturient;

[0015] 3. The maternity pad can be replaced by simply pulling out the nursing board, which not only facilitates the operation of medical staff, but also does not require the mother to turn over drastically, reducing unnecessary risks. Through the adaptation of the track groove and the sliding track, a certain supporting force is provided for the second hinge block to ensure that the screw rod will not fully bear the pressure from the support plate, thereby increasing the service life of the screw rod.

[0024] During use, the medical staff places the placement board 1 on the bed, and the parturient can sit on the anti-slip groove 21 on the placement board 1 with her back against the seat back 2. At this time, the drive motor 8 can be started, and the output end of the drive motor 8 rotates to drive the screw 7 to rotate counterclockwise. The second hinge block 6 is restricted by the limit slot 3 so that the second hinge block 6 can only move along the length direction of the screw 7. At this time, the second hinge block 6 will move in the direction of the drive motor 8, and the movement of the second hinge block 6 will drive the lower end of the support plate 4 to move together, and the seat back 2 and the support plate 4 will be in a state of opposite inclination.

[0027] During use, when the parturient leans back, her buttocks will contact the inclined surfaces of the two rubber shields 18, and the blocking blocks 17 inside the rubber shields 18 provide a certain support force for the parturient's buttocks, ensuring that the back of the pregnant woman will not slide down during the leaning back process, thereby improving the comfort of the parturient.

[0028] During the delivery process, the medical staff can spread the maternity pad flat on the nursing board 20. If it needs to be replaced, the mother can step on the protrusions on the blocking block 17 with both feet and exert force with both legs. At this time, the mother's buttocks will be slightly lifted, and the medical staff can pull the nursing board 20 out from the inside of the limit opening 19 to replace the maternity pad. Replacing the maternity pad by simply pulling out the nursing board 20 not only facilitates the operation of the medical staff, but also does not require the mother to turn over drastically, reducing unnecessary risks.
