Description

Technical Field

[0001] This utility model relates to the field of prenatal examination technology, specifically to a prenatal examination auxiliary device for placenta previa with high risk of complications. Background Technology

[0002] Placenta previa accreta is a condition where a woman has a history of cesarean section or myomectomy, and the placenta is attached to the previous surgical scar. This carries a high risk of placenta accreta and fatal hemorrhage. Placenta previa accreta is the most severe type of placenta previa, with a high probability of placenta accreta. It is associated with recurrent vaginal bleeding during pregnancy and a high risk of fatal hemorrhage during surgery. It is a serious complication of pregnancy and should be treated in a hospital with the necessary facilities.

[0003] To ensure the safety of mothers with placenta previa at high risk of complications, prenatal examinations are necessary before delivery. Normally, this requires the pregnant woman to lie on an examination bed. However, due to labor pains and exhaustion, pregnant women often find it difficult to lie down, and they are often unable to place their legs on the leg support board, thus affecting the prenatal examination. Therefore, we need to propose an auxiliary device for prenatal examinations of placenta previa at high risk of complications. Utility Model Content

[0004] The purpose of this invention is to provide a prenatal examination auxiliary device for placenta previa with high risk. By raising the backrest, the pregnant woman sits on the seat board and leans against the backrest, placing her feet inside the two sets of support leg arc plates. Then, the headrest is adjusted to a suitable position, moving the limiting module away from the side connecting plate. The rotating column is then rotated to slowly rotate the backrest, thereby slowly making the pregnant woman lie down. At the same time, the two sets of support leg arc plates follow the movement of the backrest to support the pregnant woman's legs, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a prenatal examination auxiliary device for placenta previa with high risk, comprising a seat board and a backrest rotatably mounted on the side of the seat board, wherein two sets of connecting columns are symmetrically arranged on the side of the backrest near the seat board, and a support leg arc plate is fixedly mounted on the end of the two sets of connecting columns away from the backrest.

[0006] The side of the backrest is provided with a leveling component for rotating the backrest to flatten it.

[0022] 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.

[0023] This utility model provides: a prenatal examination auxiliary device for placenta previa with high risk of complications, such as... Figures 1-4 As shown, the device includes a seat panel 1 and a backrest 4 that is rotatably mounted on the side of the seat panel 1. Two sets of connecting columns 3 are symmetrically arranged on the side of the backrest 4 closest to the seat panel 1, and leg support arc plates 2 are fixedly mounted on the ends of the two sets of connecting columns 3 away from the backrest 4. When a pregnant woman sits on the surface of the seat panel 1, she places her legs inside the two sets of leg support arc plates 2, and then rotates the backrest 4 to flatten it. At this time, the two sets of leg support arc plates 2 will slowly rise along with the backrest 4, thereby raising the pregnant woman's legs, which makes it easier for medical staff to conduct prenatal examinations on pregnant women with placenta previa.

[0024] Preferably, the backrest 4 is provided with a leveling component on its side for rotating and leveling the backrest 4. The leveling component includes front support legs 10, rotating columns 12, bolted plates 14, support modules, and limiting modules. There are two sets of front support legs 10 and bolted plates 14. The two sets of front support legs 10 are rotatably connected to the corresponding bolted plates 14 through rotating columns 12, and the two sets of bolted plates 14 are bolted to the lower surface of the backrest 4. The two sets of folding support legs 8 are rotatably disposed inside the bolted plates 14 through rotating columns 12, and the rotating columns 12 are threadedly connected to the bolted plates 14. The rotating columns 12 are fixedly connected to the two sets of folding support legs 8. When the rotating columns 12 rotate relative to the bolted plates 14, the rotating columns 12 will synchronously drive the front support legs 10 to rotate, thereby slowly leveling the backrest 4, and thus allowing the pregnant woman to lie flat for examination.

[0025] Furthermore, the support module includes folding legs 8, side connecting plates 9, and connecting plates 13. Each of the folding legs 8, side connecting plates 9, and connecting plates 13 has two sets. One end of each set of side connecting plates 9 is rotatably connected to the corresponding folding leg 8, and the other end of each set of side connecting plates 9 is rotatably connected to the corresponding front support leg 10. One set of connecting plates 13 is positioned between the two sets of folding legs 8, and the other set of connecting plates 13 is positioned between the two sets of front support legs 10. Several sets of fixed legs 11 are provided on the lower surface of the seat plate 1. Furthermore, the bottom ends of the folding legs 8, the front legs 10, and the fixed legs 11 are all equipped with anti-slip pads. A connecting plate 13 is provided to improve the stability of the two sets of folding legs 8 and the two sets of front legs 10. A side connecting plate 9 is provided to rotatably connect the two sets of folding legs 8 to the corresponding front legs 10, reducing the floor space occupied by the folding legs 8 when the backrest 4 is folded up. At the same time, when the backrest 4 is flat, the folding legs 8, the front legs 10, and the fixed legs 11 are in contact with the ground through the anti-slip pads, thereby improving the stability of the overall device during use.

[0026] Furthermore, the limiting module includes a fixed sleeve 18, a limiting plate 19, a movable column 20, and a locking column 22. The fixed sleeve 18 is fixedly installed on the outside of a set of front support legs 10. The limiting plate 19 and the locking column 22 are respectively installed at both ends of the movable column 20, and both the movable column 20 and the locking column 22 are slidably installed inside the fixed sleeve 18. The locking column 22 is located below the corresponding side connecting plate 9. The limiting plate 19 is located on the side of the fixed sleeve 18 away from the connecting plate 13. A compression spring 21 is sleeved on the outer arc surface of the movable column 20, and one end of the compression spring 21 is fixedly installed on the fixed sleeve 18. Inside the fixed sleeve 18, when the backrest 4 is folded up, the moving column 20 and the locking column 22 extend out from inside the fixed sleeve 18 under the action of the compression spring 21. At this time, the locking column 22 contacts the corresponding side connecting plate 9 and locks the corresponding side connecting plate 9 to prevent the side connecting plate 9 from continuing to rotate, thereby limiting the backrest 4. When the backrest 4 needs to be flattened, the limiting plate 19 drives the moving column 20 and the locking column 22 to move outward of the fixed sleeve 18, thereby driving the locking column 22 away from the side connecting plate 9, so that the backrest 4 can continue to rotate and flatten.

[0027] Specifically, two sets of side panels 5 are symmetrically arranged on the upper surface of the backrest 4. Two sets of extension blocks 6 are fixedly arranged on the side of the backrest 4 away from the seat panel 1. A pillow 7 is slidably arranged between the two sets of extension blocks 6. Moving blocks 16 are symmetrically arranged on both sides of the pillow 7. The corresponding surfaces of the two sets of extension blocks 6 are provided with moving grooves 15 corresponding to the moving blocks 16. A lead screw 17 is rotatably arranged inside one set of extension blocks 6, and a set of moving blocks 16 is threaded onto the outer arc surface of the lead screw 17. The pillow 7 is set to support the head of the pregnant woman. Then, by rotating the lead screw 17, the moving blocks 16 are moved up and down through the thread, thereby moving the pillow 7 between the two sets of extension blocks 6, so that the pillow 7 is suitable for pregnant women of different heights.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
