Description

Technical Field

[0001] The present application relates to the technical field of delivery auxiliary devices, and in particular to a multifunctional delivery auxiliary chair. Background Art

[0002] Childbirth refers to the emergence of a new individual from the mother's body, specifically the period and process when the fetus is separated from the mother's body and exists independently. Factors affecting childbirth should include labor force, birth canal, fetus and mental factors. During childbirth, since the labor force of childbirth mainly depends on the contraction force of the uterus and the fetus's own gravity, it is most conducive to the delivery of the mother when the gravity of the fetus is consistent with the direction of the birth axis. If a sitting or semi-sitting position is adopted for childbirth, it can promote pelvic expansion, which is conducive to the descent of the fetus and relieves the discomfort of the mother's back. During a sitting delivery, the height and direction of the seat are not easy to adjust, and it is impossible to adjust in time according to the height and body of the pregnant woman, which makes the pregnant woman feel uncomfortable, which may affect the entire delivery process. Therefore, a multifunctional delivery auxiliary chair is proposed. Utility Model Content

[0014] 1. When the height of the auxiliary chair needs to be increased, the hand wheel is turned, and the worm fixedly connected to the hand wheel rotates at the same time, the worm drives the worm wheel to rotate, and the rotation of the worm wheel drives the screw to move upward. Since the upper end of the screw is fixedly connected to the chassis, the chassis moves upward at the same time, and the seat cushion fixedly installed on the upper end of the chassis moves upward at the same time, and the height of the auxiliary chair is increased. When the height of the auxiliary chair needs to be lowered, the hand wheel is turned in the opposite direction, and the worm fixedly connected to the hand wheel rotates in the opposite direction at the same time, the worm drives the worm wheel to rotate in the same direction, and the reverse rotation of the worm wheel drives the screw to move downward. Since the upper end of the screw is fixedly connected to the chassis, the chassis moves downward at the same time, and the seat cushion fixedly installed on the upper end of the chassis moves downward at the same time, and the height of the auxiliary chair is lowered.

[0015] 2. When adjusting the height of the delivery auxiliary chair, the partition can limit the lowest height of the auxiliary chair, separating the telescopic rod from the worm gear, so that the telescopic rod will not reach the worm gear position and get stuck when moving downward.

[0016] 3. When adjusting the height of the delivery auxiliary chair, the limit plate limits the maximum adjustment of the auxiliary chair, so that the screw will not completely disengage from the threaded hole and fall out when moving upward. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present application is further described in detail below in conjunction with the accompanying drawings.

[0025] Example, see Figures 1 to 6 A multifunctional delivery auxiliary chair comprises a support rod 7, the support rod 7 is hollow inside, a worm 13 is rotatably connected inside the support rod 7, the worm 13 is horizontally connected to the inner wall of the support rod 7, the worm 13 is meshedly connected with a worm wheel 14, the lower end of the worm wheel 14 is rotatably connected to a connecting rod 15, a bottom plate 9 is fixedly installed at the lower end of the connecting rod 15, a threaded hole 20 is provided in the middle of the worm wheel 14, a bolt 11 is rotatably connected in the threaded hole 20, a chassis 5 is provided at the upper end of the bolt 11, the bolt 11 is rotatably connected to the chassis 5, a telescopic rod 6 is provided outside the bolt 11, the telescopic rod 6 is fixedly installed at the lower end of the chassis 5, the telescopic rod 6 is slidably connected to the support rod 7, a seat cushion 3 is fixedly installed at the upper end of the chassis 5, a backrest 1 is fixedly installed on one side of the seat cushion 3, a hand wheel 8 is provided on one side of the support rod 7, and the hand wheel 8 is fixedly connected to one side of the worm 13.

[0026] When it is necessary to increase the height of the auxiliary chair, the hand wheel 8 is rotated, and the worm 13 fixedly connected to the hand wheel 8 rotates at the same time, the worm 13 drives the worm wheel 14 to rotate, and the rotation of the worm wheel 14 drives the screw rod to move upward. Since the upper end of the screw rod is fixedly connected to the chassis 5, the chassis 5 moves upward at the same time, and the seat cushion 3 fixedly installed on the upper end of the chassis 5 moves upward at the same time, and the height of the auxiliary chair is increased. When it is necessary to lower the height of the auxiliary chair, the hand wheel 8 is rotated in the opposite direction, and the worm 13 fixedly connected to the hand wheel 8 rotates in the opposite direction at the same time, the worm 13 drives the worm wheel 14 to rotate, and the reverse rotation of the worm wheel 14 drives the screw rod to move downward. Since the upper end of the screw rod is fixedly connected to the chassis 5, the chassis 5 moves downward at the same time, and the seat cushion 3 fixedly installed on the upper end of the chassis 5 moves downward at the same time, and the height of the auxiliary chair is lowered.

[0027] Reference Figure 1 , Figure 2 , Figure 3 as well as Figure 5 A hand wheel 8 is provided on one side of the support rod 7, and the hand wheel 8 is fixedly connected to one side of the worm 13. When the height of the delivery auxiliary chair needs to be adjusted, rotating the hand wheel 8 can drive the worm wheel 14 and the worm 13 to move, thereby adjusting the height of the auxiliary chair.

[0028] Reference Figure 2 as well as Figure 3 A partition 12 is fixedly installed above the worm gear 14. When adjusting the height of the delivery auxiliary chair, the partition 12 can limit the lowest height of the auxiliary chair, separate the telescopic rod 6 from the worm gear 13, so that the telescopic rod 6 will not reach the position of the worm gear 14 and get stuck when moving downward.

[0029] Reference Figure 2 as well as Figure 3 The lower end of the bolt 11 is fixedly mounted with a limit plate 21. When adjusting the height of the delivery auxiliary chair, the limit plate 21 limits the maximum adjustment of the auxiliary chair so that the screw rod will not completely disengage from the threaded hole 20 and fall out when moving upward.

[0030] Reference Figure 1 The cushion 3 is provided with a U-shaped opening 22, and the use of the U-shaped cushion 3 may improve the safety of childbirth. The upright delivery posture helps to reduce the compression of the aorta by the parturient, provide a better oxygen supply to the fetus, and reduce the risk of hypoxia and acidosis.

[0031] Reference Figure 1 The seat cushion 3 is provided with handles 2 fixedly mounted on both sides, and the handles 2 enable the parturient to find a more comfortable and relaxed posture during childbirth. By grasping the handles 2, additional support is obtained. This helps the parturient to maintain a stable posture during uterine contractions and labor pains, and can exert force by grasping the handles 2 to reduce the pressure during childbirth. The parturient can adjust her posture and breathing more naturally, reducing the tension and discomfort caused by childbirth.

[0032] Reference Figure 1 as well as Figure 4 Universal wheels 10 are provided at the lower ends of the four corners of the bottom plate 9. When the delivery auxiliary chair needs to be moved, the universal wheels 10 can more conveniently move the delivery auxiliary chair.

[0033] Reference Figure 1 as well as Figure 4 A fixing plate 18 is provided above both sides of the universal wheel 10, and a rotating rod 16 is rotatably connected between the fixing plates 18. A paddle 17 is fixedly installed on the upper end of the rotating rod 16, and a fixing block 19 is provided at the lower end of the rotating rod 16. When the delivery auxiliary chair does not need to be moved, the paddle 17 can be pushed down to make the fixing block 19 rotate downward and abut against the universal wheel 10 so that it will not slide. When the delivery auxiliary chair does not need to be moved, the paddle 17 can be pushed upward to make the fixing block 19 rotate upward and no longer abut against the universal wheel 10, so that the fixing block 19 no longer restricts the movement of the universal wheel 10.

[0034] Reference Figure 1Two connecting plates 23 are provided at the lower end of the cushion 3, and a pedal 4 is provided above one end of the two connecting plates 23. The pedal 4 allows the pregnant woman to put her feet on the pedal 4 and open her legs at a certain angle, which is convenient for the pregnant woman to exert force on her lower abdomen and avoid the pregnant woman clamping her legs due to pain, thereby speeding up the delivery process and protecting the safety of the pregnant woman and the fetus during delivery.

[0035] Working principle: when the height of the auxiliary chair needs to be increased, the hand wheel 8 is turned, and the worm 13 fixedly connected to the hand wheel 8 rotates at the same time, the worm 13 drives the worm wheel 14 to rotate, and the rotation of the worm wheel 14 drives the screw rod to move upward. Since the upper end of the screw rod is fixedly connected to the chassis 5, the chassis 5 moves upward at the same time, and the seat cushion 3 fixedly installed on the upper end of the chassis 5 moves upward at the same time, and the height of the auxiliary chair is increased. When the height of the auxiliary chair needs to be lowered, the hand wheel 8 is turned in the opposite direction, and the worm 13 fixedly connected to the hand wheel 8 rotates in the opposite direction at the same time, the worm 13 drives the worm wheel 14 to rotate, and the reverse rotation of the worm wheel 14 drives the screw rod to move downward. Since the upper end of the screw rod is fixedly connected to the chassis 5, the chassis 5 moves downward at the same time, and the seat cushion 3 fixedly installed on the upper end of the chassis 5 moves downward at the same time, and the height of the auxiliary chair is lowered.
