Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to an auxiliary device for correcting abnormal fetal position. Background Art

[0002] Abnormal fetal position is most commonly persistent occiput transverse position and occiput posterior position, which can lead to uterine atony, prolonged or arrested labor, etc. It is an important factor in increasing the conversion rate to cesarean section and aggravating the harm to mother and baby.

[0003] Currently, in the late stages of pregnancy and delivery, you can coordinate your breathing and train your pelvic floor muscles through "hip opening" to increase labor force and promote the entry of the fetal head into the pelvis. The hip joint is a ball-and-socket joint that has the ability to internally rotate and externally rotate the acetabulum and femur. The external rotators (piriformis, mentalis superioris, obturator internus, mentalis inferior, quadratus femoris and obturator externus, etc.) produce external rotation of the hip, help stabilize the pelvis, and are located deep in the buttocks. The internal rotators of the hip are also called hip abductors, and their main function is abduction. Hip internal rotation is its secondary function. Hip internal rotation is the synergistic action of the adductor brevis and long muscles and the upper part of the adductor magnus.

[0004] However, the existing equipment cannot meet the needs of pregnant women to complete hip opening exercises independently, requires a large amount of midwifery human resources, and has little effect. Utility Model Content

The knee fixed seat 31 is a hollow arc-shaped plate structure with a notch on it at the lower part, and the hollow arc-shaped plate structure is covered with an airbag.

[0048] The utility model transmits the motion of the knee transmission motor to the bending rotating part, drives the bending part at the tail of the bending rotating part to perform circular motion, and then transmits the motion to the rotating cylinder connected to it. The rotating cylinder then transmits the circular motion to the knee fixing seat connected to the lower part through a universal coupling to achieve the effect of the knee fixing seat performing circular motion.

[0049] The universal coupling in the present invention can be replaced by any small component that achieves the same effect as the universal coupling. When using the universal coupling or a component that achieves the same effect, the type of universal coupling can be selected according to actual conditions to ensure the effect of the universal coupling.

[0050] The lower portion of the knee mount features a hollow, curved structure that secures the pregnant woman's knees. Slots in the hollow curved plate allow for the insertion of straps, securing the knee mount to the pregnant woman's knees. This assists the pregnant woman's knees in circular motion, correcting abnormal fetal position. The upper end of the knee mount is connected to a universal coupling, allowing it to rotate freely during the assistive movement. The hollow curved plate also encloses the airbag, enhancing the device's comfort.

[0051] Specifically, in this embodiment, the opening and closing lifting assembly includes a knee opening and closing motor 14, a mounting base 12, a first connecting plate 15, a sliding mounting plate, a second connecting plate 19, a third connecting plate 20, a first rotating shaft 21, a second rotating shaft 22, and a middle transmission shaft 13;

[0052] The knee opening and closing motor 14 is connected to the middle transmission shaft 13 via a coupling, and the middle transmission shaft 13 is connected to the mounting base 12 via a bearing;

[0053] The mounting base 12 is connected to the mounting slider 9 by bolts. A slide groove is provided inside the mounting base 12. A polished rod is symmetrically mounted with the central axis of the slide groove. The sliding mounting plate passes through the polished rod and slides on it.

[0054] The sliding mounting plate includes a first sliding mounting plate 18 located on the left and a second sliding mounting plate 17 located on the right, wherein the first sliding mounting plate 18 and the second sliding mounting plate 17 are symmetrically mounted with the central axis of the opening and closing lifting assembly as the center;

[0055] The first sliding mounting plate 18 is connected to the knee first action component through a double mounting fixing seat 25, and the second sliding mounting plate 17 is connected to the knee second action component through a double mounting fixing seat 25. The first sliding mounting plate 18 is fixed to the double mounting fixing seat 25 by bolts, and the second sliding mounting plate 17 is fixed to the double mounting fixing seat 25 by bolts.

[0058] The utility model is also provided with an opening and closing lifting component on the connection of the knee assembly. Figure 3-5 It can be seen that the rotation of the first connecting plate and the middle transmission shaft is fixed, so the action of the knee lifting motor will be transmitted to the first connecting plate to rotate it. The second connecting plate and the third connecting plate are driven to move inward or outward at the same time, thereby driving the first sliding mounting plate and the second sliding mounting plate to perform corresponding actions, so that the two knee fixing seats are opened and closed at the same time, so that the utility model can adapt to the different opening and closing situations when pregnant women bend their knees to perform circular movements of the knees. Since the sliding mounting plate needs to be installed with a knee fixing seat at its lower installation, a light rod is installed in the slide groove of the mounting seat in this auxiliary device to pass through the sliding mounting plate to share the weight on the sliding mounting plate, making its sliding state more stable. A straight groove and a fixing buckle are provided on the rotating shaft to facilitate the maintenance of the opening and closing component connecting plate.
