Description

Technical Field

[0001] This utility model relates to the field of hip elevation technology, and in particular to a hip elevation pillow for premature rupture of membranes. Background Technology

[0002] Premature rupture of membranes (PROM) refers to the spontaneous rupture of the amniotic sac before labor. Causes of PROM include trauma, cervical insufficiency, infection, increased amniotic pressure, poor engagement of the presenting part of the fetus with the pelvic inlet, and poor amniotic membrane development. After PROM, the buttocks need to be elevated to prevent umbilical cord prolapse, reduce amniotic fluid leakage, and lower the risk of infection. Clinically, the method of elevating the pregnant woman's buttocks is commonly used, keeping her in a head-down, hip-up position, generally at a height of 10-15°. This can reduce the amount of amniotic fluid leakage to some extent. Examples include existing technologies such as CN213098950U (a PROM protection mechanism) and CN211271850U (a maternity pad for PROM).

[0003] Currently, existing techniques for elevating the pregnant woman's hips can only reduce the outflow of amniotic fluid. Some amniotic fluid will still flow out of the uterus and down the vagina, continuously flowing onto the hospital bed. This not only increases the discomfort of the pregnant woman in the bed but also increases the workload of medical staff in cleaning. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a buttock-elevating pillow for premature rupture of membranes. The technical problem to be solved by this utility model is that the continuous flow of amniotic fluid onto the hospital bed increases the discomfort of pregnant women in the bed and the workload of medical staff in cleaning.

[0032] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of this utility model. Based on the description of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0033] This utility model provides a buttock-elevating pillow for premature rupture of membranes, such as... Figure 1-6As shown, it includes an elevation component 1 for raising the buttocks and a collection component 2 for collecting amniotic fluid.

[0034] Specifically, the lifting assembly 1 includes a base plate 11 and an inclined plate 12 located on top of the base plate 11. One side of the base plate 11 is rotatably connected to one side of the inclined plate 12. An electric push rod 13 is provided between the base plate 11 and the inclined plate 12, with both ends of the electric push rod 13 rotatably connected to the top of the base plate 11 and the bottom of the inclined plate 12, respectively. In actual use, a battery can be installed on the top of the base plate 11 to power the electric push rod 13. The electric push rod 13 is remotely controlled by an infrared remote controller. The infrared remote controller converts electrical signals into infrared signals through an infrared LED and sends them out. The infrared receiver installed on the electric push rod 13 receives the infrared signals, thereby controlling the electric push rod 13. Infrared remote control technology is a commonly used existing technology and will not be described further here.

[0035] When in use, the inclined board 12 is placed under the pregnant woman's buttocks to elevate them and reduce amniotic fluid leakage. A soft pad 15 is also fixed at the top of the inclined board 12 to further enhance the pregnant woman's comfort. Then, the electric push rod 13 can be activated to drive one side of the inclined board 12 to rotate around one side of the base plate 11 to adjust the angle of the inclined board 12, thereby adjusting the angle at which the buttocks are raised. This method is suitable for different pregnant women and has a wide range of applications.

[0036] like Figures 3-6 As shown, the collection component 2 includes a box body 21 and a movable plate 22 located on the top of the box body 21. The movable plate 22 has a flow port 23 that passes through it. The top of the movable plate 22 is fixed to an upper frame 24 outside the flow port 23, and a limit frame 25 is fixed to the top of the upper frame 24.

[0037] The other side of the base plate 11 is fixedly connected to the bottom of one side of the box body 21. A connecting plate 5 is provided between the other side of the inclined plate 12 and the top of one side of the movable plate 22. The connecting plate 5 includes an outer plate 51 and an inner plate 52 located on the side of the outer plate 51 near the movable plate 22. One side of the inner plate 52 extends into the interior of the outer plate 51 and is slidably connected to the outer plate 51. The other side of the inner plate 52 is fixedly connected to one side of the movable plate 22, and the side of the outer plate 51 near the inclined plate 12 is rotatably connected to the other side of the inclined plate 12. The bottom of the movable plate 22 extends into the interior of the box body 21 and is slidably connected to the box body 21.

[0038] When the inclined plate 12 is raised and lowered on the other side, the movable plate 22 is driven to move up and down along the box 21 through the connecting plate 5, so that the movable plate 22 is always located at the bottom of the pregnant woman's vagina. The amniotic fluid flowing out of the pregnant woman's vagina enters the box 21 through the drainage port 23 for collection, reducing the amount of amniotic fluid flowing onto the bed, reducing the discomfort of the pregnant woman and reducing the cleaning workload of medical staff.

[0039] To facilitate cleaning of the box 21, a round hole 26 is provided at the bottom of the box 21, and a cover plate 27 is threaded into the round hole 26. The top of the cover plate 27 is provided with a sealing ring 28 for sealing the round hole 26. By rotating and opening the cover plate 27, the box 21 can be cleaned through the round hole 26.

[0040] like Figures 1-3 As shown, a pad 3 is also provided on the outside of the lifting component 1 and the collecting component 2. The top of the pad 3 has an opening 1 that surrounds the outside of the upper frame 24, and an elastic band is sewn in the opening 1 to tightly wrap the opening 1 around the outside of the upper frame 24. The pad 3 has an opening 2 on the side near the collecting component 2, and a zipper 4 is sewn in the opening 2.

[0041] The pad cover 3 includes an inner waterproof cover 31 and an outer absorbent cover 32, with the waterproof cover 31 and absorbent cover 32 fixed together. The absorbent cover 32 can be made of pure cotton or degreased cotton, etc.: pure cotton has excellent moisture absorption and breathability. Degreased cotton: refers to cotton that has been chemically treated to remove grease. It is made from raw cotton by removing impurities, degreasing, bleaching, washing, drying, and finishing, and is more likely to absorb liquids than ordinary cotton.

[0042] The absorbent cover 32, made of pure cotton or degreased cotton, not only increases the comfort of pregnant women but also absorbs any amniotic fluid that may leak onto the bed, further reducing the amount of amniotic fluid that may reach the bed. The waterproof cover 31 prevents amniotic fluid from seeping into the pad cover 3 and soiling or damaging the lifting assembly 1 and the collection assembly 2. The zipper 4 allows for easy removal of the pad cover 3 for cleaning.

[0043] In addition, handles 14 are fixed at both the front and rear ends of the base plate 11. Both handles 14 extend outside the pad cover 3, allowing pregnant women to hold the handles 14 to get up easily.

[0044] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
