Description

A leg-flexing assistive device for delivery rooms Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a leg-flexion assistive device for the delivery room. Background Technology

[0002] During childbirth, the correct position plays a crucial role in a smooth delivery. Assisting the mother to bend her legs is a key technique. When the mother is in a suitable leg-bending position, it effectively increases the pelvic diameter, creating more favorable space for the baby's delivery. It also helps the mother exert more force, reducing physical exertion during labor, lowering the risk of dystocia, and greatly improving the safety and efficiency of childbirth.

[0003] However, most existing devices for assisting mothers in flexing their legs use a fixed method to achieve this movement. While this fixed method can maintain the flexed position to some extent, it brings a significant problem: the mother's legs cannot move independently. When maintaining a fixed flexed position for a long time, the leg muscles are prone to soreness and numbness due to lack of activity. This not only increases the mother's physical discomfort during childbirth but may also affect the mother's normal pushing rhythm. In addition, the inability to move the legs independently also limits the mother's ability to make minor adjustments to her position based on her own feelings and the progress of labor, making it difficult to find the most comfortable and conducive position for childbirth, which to some extent affects the delivery outcome. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a leg-flexion assistive device for the delivery room. This design uses an airbag to relieve the pressure on the rotating shaft of the connecting rod and the hinged bracket, allowing for flexible rotation. The device can be tightened and loosened in conjunction with the delivery process, providing the mother's legs with a certain degree of freedom of movement. Furthermore, it can fix the mother's legs when she is exhausted.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A leg-flexion assist device for delivery rooms includes two sets of piston-type adjusting sleeves. A connecting rod is fixedly connected to the top of each set of piston-type adjusting sleeves. A hinge bracket is connected to the top of each connecting rod via a pin. A fixing plate is fixedly connected to the top of each hinge bracket. A water-storing shell is installed in the middle of the outer wall of each hinge bracket. A compressible elastic membrane is connected to the inner wall of the water-storing shell. The compressible elastic membrane is tightly attached to the rotation axis of the connecting rod and the hinge bracket. A pressure injection pipe is fixedly connected to the outer wall of the water-storing shell, and an air guiding assembly is connected to the other end of the pressure injection pipe.

[0007] Through the above technical solution, the device introduces liquid into the inner water storage shell through the injection pipe to keep the squeeze elastic membrane under high pressure, thereby restricting the rotation of the connecting rod and the limiting component. When the connecting rod and the hinge bracket cannot rotate relative to each other, the mother's legs can be fixed, avoiding the situation where the mother is unable to maintain the bent leg due to exhaustion.

[0008] Furthermore, the air guiding assembly includes a three-way pipe, the top of which is fixedly connected to a pressure storage shell. The inner top of the pressure storage shell is connected to a pressure holding spring tube via a spring. A branch pipe is fixedly connected to the outer wall of the pressure storage shell. A side wedge rod is connected to the branch pipe via a spring. The side wedge rod and the pressure holding spring tube cooperate with each other through a wedge groove and a wedge-shaped protrusion. An active wedge rod is connected to the outer wall of the branch pipe via a spring. The protrusion on the active wedge rod cooperates with the wedge groove of the side wedge rod.

[0009] With the above technical solution, when the active wedge rod is pressed and moves closer to the side wedge rod, the active wedge rod drives the side wedge rod away from the pressure-holding spring tube. The pressure-holding spring tube moves upward under the action of the spring, so that the water originally stored in the water storage shell is extracted through the injection pipe and the three-way pipe. This causes the originally squeezed elastic membrane to lose pressure, and the rotating shaft of the connecting rod and the hinge bracket is no longer squeezed and can rotate flexibly.

[0010] Furthermore, an air supply pipe is fixedly connected to the outer wall of the pressure storage shell and to the front of the active wedge rod, and the other end of the air supply pipe is connected to a compression airbag.

[0011] With the above technical solution, the compression airbag can be held in the hand during childbirth. When the mother squeezes the airbag tightly, the rotating shaft of the connecting rod and the hinge bracket is no longer squeezed and can rotate flexibly. The device can be tightened and loosened and fixed in conjunction with the mother's childbirth. The mother's legs have a certain amount of free movement space, and the mother's legs can be fixed when she is exhausted.

[0012] Furthermore, a limiting component is fixedly connected to the bottom middle position of the fixed plate. The limiting component includes a limiter, and a limiting pressure block is threadedly connected to the rear side wall of the limiter. Limiting ropes are connected to the inner side walls of the two connecting rods, and the limiting ropes pass through the rope groove portion of the limiter and the limiting pressure block.

[0013] Through the above technical solution, the limiting component can limit the range of motion of the mother's legs to a certain extent, preventing the mother's legs from being fully straightened. During adjustment, the limiting rope is partially pulled out of the limiter according to the mother's maximum relaxation angle. When the mother's legs are out of control and she wants to straighten them, the two limiting ropes can limit the mother's legs.

[0014] Furthermore, a main binding member is installed on the front side wall of the piston-type adjusting sleeve, and a movable binding member is installed on the movable end of the piston-type adjusting sleeve;

[0015] The above technical solution uses a main binding component to fix the piston-type adjusting sleeve to the mother's thighs and calves. The movable end of the piston-type adjusting sleeve can be adjusted according to the length of the mother's thighs and calves to fit the mother's body shape.

[0016] Furthermore, both the main binding and the movable binding are provided with straps for securing the patient's legs;

[0017] The above technical solution allows the device to be flexibly attached to the patient's leg by swinging.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, during childbirth, the compression airbag can be held in the hand. When the mother squeezes the airbag tightly, the rotating shaft of the connecting rod and the hinge bracket is no longer squeezed and can rotate flexibly. The device can be tightened and loosened and fixed in coordination with the mother's childbirth. The mother's legs have a certain amount of free movement space, and the mother's legs are fixed when she is exhausted.

[0020] 2. In this utility model, the limiting component can limit the range of motion of the mother's legs to prevent the mother's legs from being fully extended. During adjustment, the limiting rope is pulled out of the limiter according to the mother's maximum relaxation angle. When the mother's legs are out of control and she wants to straighten them, the two limiting ropes can limit the mother's legs. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example: Referring to Figures 1-5, one embodiment of this utility model provides a leg-flexion assist device for delivery rooms, including two sets of piston-type adjusting sleeves 1. A connecting rod 4 is fixedly connected to the top of each set of piston-type adjusting sleeves 1. A hinge bracket 6 is connected to the top of each connecting rod 4 via a pin. A fixing plate 7 is fixedly connected to the top of each hinge bracket 6. A water storage shell 14 is installed in the middle of the outer side wall of the hinge bracket 6. A compression elastic membrane 15 is connected to the inner side wall of the water storage shell 14, and the compression elastic membrane 15 is tightly attached to the connecting rod 4. A pressure injection tube 16 is fixedly connected to the outer wall of the water storage shell 14 on the rotation axis of the hinge bracket 6. The other end of the pressure injection tube 16 is connected to the air guiding component 13. The device introduces liquid into the inner water storage shell 14 through the pressure injection tube 16 to keep the elastic membrane 15 under high pressure, thereby restricting the rotation of the connecting rod 4 and the limiting component 5. When the connecting rod 4 and the hinge bracket 6 cannot rotate relative to each other, the mother's legs can be fixed, avoiding the situation where the mother is unable to maintain the bent legs due to exhaustion.

[0031] The air guiding assembly 13 includes a three-way pipe 135. A pressure storage shell 131 is fixedly connected to the top of the three-way pipe 135. A pressure holding spring tube 133 is connected to the inner top of the pressure storage shell 131 via a spring. A branch pipe 132 is fixedly connected to the outer wall of the pressure storage shell 131. A side wedge rod 134 is connected to the branch pipe 132 via a spring. The side wedge rod 134 and the pressure holding spring tube 133 cooperate with each other through a wedge groove and a wedge-shaped protrusion. An active wedge rod 136 is connected to the outer wall of the branch pipe 132 via a spring. The protrusion on the active wedge rod 136 cooperates with the wedge groove of the side wedge rod 134. When the active wedge rod 136 is pressed and moves closer to the side wedge rod 134, the active wedge rod 136 drives the side wedge rod 134 away from the pressure holding spring tube 133. The pressure holding spring tube 133, when subjected to pressure... Driven by the spring, the device moves upward, causing the water stored in the water storage shell 14 to be drawn out through the injection pipe 16 and the three-way pipe 135. This causes the previously compressed compression elastic membrane 15 to lose pressure, and the rotating shaft of the connecting rod 4 and the hinge bracket 6 is no longer compressed and can rotate flexibly. An air supply pipe 9 is fixedly connected to the outer wall of the pressure storage shell 131 and to the front of the active wedge rod 136. The other end of the air supply pipe 9 is connected to a compression airbag 8. During childbirth, the mother can hold the compression airbag 8 in her hand. When the mother squeezes the compression airbag 8 tightly, the rotating shaft of the connecting rod 4 and the hinge bracket 6 is no longer compressed and can rotate flexibly. This device can be tightened and loosened and fixed in conjunction with the mother's childbirth. The mother's legs have a certain amount of free movement space, and the mother's legs are fixed when she is exhausted.

[0032] A limiting component 5 is fixedly connected to the bottom center of the fixing plate 7. The limiting component 5 includes a limiter 10. A limiting pressure block 11 is threadedly connected to the rear side wall of the limiter 10. Limiting ropes 12 are connected to the inner side walls of the two connecting rods 4. The limiting ropes 12 pass through the rope grooves of the limiter 10 and the limiting pressure block 11. The limiting component 5 can limit the range of motion of the mother's legs to a certain extent, preventing the mother's legs from being fully straightened. During adjustment, the limiting rope 12 is partially pulled out of the limiter 10 according to the mother's maximum relaxation angle. When the mother's legs are uncontrollable and want to straighten, the two limiting ropes 12 can limit the mother's legs. A main binding component 2 is installed on the front side wall of the piston-type adjusting sleeve 1. A movable binding component 3 is installed on the movable end of the piston-type adjusting sleeve 1. Both the main binding component 2 and the movable binding component 3 are equipped with straps for fixing the patient's legs.

[0033] Working principle: The piston-type adjusting sleeve 1 is fixed to the mother's thighs and calves by the main binding component 2. The movable end of the piston-type adjusting sleeve 1 can be adjusted according to the length of the mother's thighs and calves to fit the mother's body shape. Liquid is introduced into the inner water storage shell 14 through the injection tube 16 to keep the compression elastic membrane 15 under high pressure, thereby restricting the rotation of the connecting rod 4 and the limiting component 5. When the connecting rod 4 and the hinge bracket 6 cannot rotate relative to each other, the mother's legs can be fixed, preventing the mother from being unable to maintain leg flexion due to exhaustion. During childbirth, the mother can hold the compression airbag 8 in her hand. When the mother squeezes the compression airbag 8 tightly, the active wedge rod 136 is pressed towards the side wedge rod 134, and the active wedge rod 136 drives the side wedge rod 134 away from the compression airbag 8. The pressure spring tube 133 is compressed, and the pressure-holding spring tube 133 moves upward under the action of the spring, so that the water originally stored in the water storage shell 14 is drawn out through the injection tube 16 and the three-way tube 135, so that the pressure-reduced elastic membrane 15 loses pressure, and the rotating shaft of the connecting rod 4 and the hinge bracket 6 is no longer compressed and can rotate flexibly. This device can be tightened and fixed in conjunction with the delivery of the mother. The mother's legs have a certain amount of free movement space, and when the mother is exhausted, the mother's legs are fixed. The limiting component 5 can limit the movement space of the mother's legs to a certain extent to prevent the mother's legs from being fully straightened. During adjustment, the part of the limiting rope 12 is pulled out of the limiter 10 according to the mother's maximum relaxation angle. When the mother's legs are uncontrollable and want to straighten, the two limiting ropes 12 can limit the mother's legs.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
