Description

Technical Field

[0001] The utility model relates to the technical field of leg expansion, in particular to a leg expansion auxiliary device for normal delivery. Background Art

[0002] During childbirth, mothers need to spread their legs to fully open the vagina to facilitate the birth of the baby. During the delivery process, due to severe pain, mothers cannot maintain the leg-opening posture well. If mothers close their legs due to pain during delivery, the baby will be stuck in the vaginal opening, affecting the baby's bones. For this reason, a leg auxiliary expansion device is needed to help the patient's legs open.

[0003] The existing announcement number is CN205849513U, which is a leg-opening auxiliary device for normal delivery. This patent uses a support block to limit the upper or lower position of the knee, and adjusts the angle of opening of the legs by adjusting the rotation angle of the connecting piece. It is easy to use and can reduce the workload of medical staff. The structure of this device is relatively simple and the cost is relatively low, making it suitable for popularization and use.

[0004] The inventors found in their daily work that the above-mentioned leg-opening auxiliary device for normal delivery requires the patient to place both legs on a support block when in use. However, due to the lack of fixing components on the support block, the patient's legs are prone to slip off the support block, thereby reducing the effectiveness of the device during actual use. Summary of the invention

[0005] The utility model aims to solve the technical problems in the above background and proposes a leg-opening auxiliary device for normal delivery.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a leg-opening auxiliary device for normal childbirth, comprising a hollow plate, two extension plates are slidably connected inside the hollow plate, a first arc block is fixedly installed on the surface of one end of the two extension plates away from the hollow plate, and the outer wall surfaces of the two first arc blocks are provided with a limiting device, the limiting device comprises a U-shaped rod, the U-shaped rod is fixedly installed on the outer wall surface of the first arc block, the surface of the U-shaped rod is slidably connected with a slide plate, and the bottom surface of the slide plate is fixedly installed with a second arc block. The setting of the first arc block and the second arc block has the effect of limiting and fixing the patient's legs.

[0007] Preferably, a circular plate is fixedly mounted on the outer wall surface of the U-shaped rod, and a spring is fixedly mounted between the circular plate and the slide plate. The arrangement of the spring has the effect of limiting the position of the slide plate on the surface of the U-shaped rod.

[0008] Preferably, a vertical plate is fixedly mounted on the surface of one end of the U-shaped rod away from the first arc block, a sleeve is fixedly mounted on the surface of the vertical plate, a top rod is slidably connected inside the sleeve, and one end of the top rod away from the sleeve is fixedly connected to the second arc block. The arrangement of the sleeve and the top rod allows the second arc block to move stably.

[0009] Preferably, the surface of the hollow plate is provided with an adjustment device, the adjustment device comprises a U-shaped plate, the U-shaped plate is fixedly mounted on the surface of the hollow plate, a threaded rod is rotatably connected between the inner walls at both ends of the U-shaped plate, and a rotating wheel is fixedly mounted on one end of the threaded rod. The setting of the rotating wheel plays an effect of driving the threaded rod to rotate.

[0010] Preferably, a vertical groove is formed on the inner wall surface of the U-shaped plate, and a T-shaped plate is threadedly connected to the surface of the threaded rod. The threaded rod has the effect of driving the T-shaped plate to move inside the vertical groove.

[0011] Preferably, both side surfaces of the T-shaped plate are hinged with hinge plates, and one end of the hinge plate away from the T-shaped plate is hinged with the extension plate. The setting of the hinge plate plays an effect of driving the extension plate to move.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, by setting a limit device, when the device needs to be used, the second arc block is first pulled, and the movement of the second arc block drives the slide plate to move on the surface of the U-shaped rod. The movement of the slide plate on the surface of the U-shaped rod will squeeze the spring, so that the spring is compressed. At the same time, the movement of the second arc block also causes the push rod to move toward the inside of the sleeve. When the distance between the moving position of the second arc block and the first arc block allows the patient's legs to pass through the two, the patient extends the legs from between the first arc block and the second arc block. After extending, the second arc block is released, and the second arc block is reset by the rebound force of the spring. The second arc block is reset and cooperates with the first arc block to limit and fix the patient's legs. Through the cooperation of the above structure, the purpose of limiting and fixing the patient's legs is achieved, thereby making the device more stable when in use.

[0014] 2. In the utility model, by arranging the adjusting device, when the patient's legs are limited and fixed, at this time, when the angle between the patient's legs is adjusted as needed, the rotating wheel is first rotated, and the rotation of the rotating wheel drives the threaded rod to rotate, and the rotation of the threaded rod drives the T-plate to move inside the vertical groove, and the movement of the T-plate inside the vertical groove drives the hinged plate to move, and the movement of the hinged plate pushes the extension plate to extend from the inside of the hollow plate, and the extension plate extends from the inside of the hollow plate to drive the two first arc blocks and the two second arc blocks to move in the direction away from each other, and the two first arc blocks and the two second arc blocks move in the direction away from each other to drive the patient's legs to separate, and when the patient's legs are separated to a suitable angle, the rotating wheel is stopped. Through the cooperation of the above structure, when the patient spreads his legs, it can be driven by the threaded rod, so that the spreading effect is stable, and it will not cause large shaking, which will cause pain in the patient's surgical site, and the practicality of the device is further improved.
