Description

Technical Field

[0001] The utility model belongs to the field of medical devices, and particularly relates to an auxiliary device for maintaining the knee joint in a straight lying position. Background Art

[0002] After the endovascular treatment of lower extremity artery stent implantation, when there is no bleeding at the puncture site and the patient can tolerate it, the patient after endovascular treatment through femoral artery puncture should stay in bed and be immobilized for 3 - 4 hours. If there is bleeding at the puncture site after the operation or the patient's own condition does not meet the requirements of getting out of bed or staying in bed, the time of immobilization and staying in bed should be extended according to the actual situation and the doctor's advice. Within 6 - 12 hours or even longer after the operation, the patient will feel very tired when keeping the knee joint in a straight state all the time, and will often bend the knee involuntarily, especially during sleep, and it is even more impossible to control it voluntarily. The disadvantage of bending the knee is that it may cause the blood vessel to bend at different angles, resulting in an increase in the blood pressure in the blood vessel and bleeding at the surgical puncture site. Therefore, an auxiliary device for straightening the knee joint is needed to effectively assist in maintaining the knee joint in a straight lying position. The existing auxiliary devices for straightening the knee joint cannot be fixed on the hospital bed. The flipping and shaking of the patient's legs in a short time after the operation are not conducive to the recovery of the condition and are likely to cause pain at the wound. Therefore, we have designed an auxiliary device for maintaining the knee joint in a straight lying position that can be fixed on the hospital bed. Content of the Utility Model

Wrap the end of the first fixing strap 3 far from the arc-shaped support portion 1 from below the crossbar of the railing 102 to above the crossbar of the railing 102, then pass through the corresponding rings 4, and then fold up the end of the first fixing strap 3 far from the arc-shaped support portion 1, so that the first magic sticker rough surface 5 and the first magic sticker hook surface 6 are adhered together, thereby fixing the arc-shaped support portion 1 on the hospital bed 101. The pulling of the first fixing straps 3 on the front and rear sides can prevent the legs 100 from flipping or shaking forward or back and forth.

[0017] Specifically, as shown in the figure, the arc-shaped support portion 1 of this embodiment includes a support plate 20 with an arc-shaped protrusion. A support sponge 21 is fixedly installed on the support plate 20. The outer sides of the support plate 20 and the support sponge 21 are wrapped with a protective cloth cover 22. The support plate 20 with an arc-shaped protrusion is placed under the legs 100, and the arc-shaped protrusion fits with the popliteal fossa of the legs 100, which conforms to ergonomics. The support sponge 21 is soft in texture, ensuring the comfort of people and preventing the legs 100 from directly contacting the hard support plate 20 and causing discomfort.

[0018] Specifically, as shown in the figure, side cloth covers 30 are fixedly installed on the front and rear sides of the arc-shaped support portion 1 of this embodiment respectively. The left and right lengths of the side cloth covers 30 are greater than the left and right lengths of the knees. Two arc-shaped side support plates 31 are respectively placed in the side cloth covers 30. The two side support plates 31 in the same side cloth cover 30 are successively located on the left and right sides of the knees. The side support plates 31 can initially fix the legs 100 and prevent the legs 100 from shaking inadvertently, which is not conducive to the recovery of the injuries of the legs 100.

[0019] Further, as shown in the figure, the left and right sides of the side cloth cover 30 in this embodiment are respectively open. The openings on the left and right sides of the side cloth cover 30 facilitate the insertion and removal of the side support plate 31.

[0020] Further, as shown in the figure, side support plates 31 with different radian can be placed in the side cloth cover 30 in this embodiment. During use, the side support plate 31 with different radian can be selected according to actual needs and placed in the side cloth cover 30, so as to effectively support different legs 100.

[0021] Furthermore, as shown in the figure, the fixing belt 2 in this embodiment includes several second fixing belts 60 and several third fixing belts 61. In this embodiment, the number of the second fixing belts 60 and the third fixing belts 61 is two respectively. The second fixing belts 60 and the third fixing belts 61 correspond one by one. One ends of the second fixing belts 60 and the third fixing belts 61 are sequentially fixed on the front and rear sides of the arc-shaped supporting part 1. The front second fixing belts 60 and the rear third fixing belts 61 are respectively located on the left and right sides of the knee. Second magic paste rough surfaces 62 are respectively fixed at the ends of the second fixing belts 60 far away from the arc-shaped supporting part 1. Second magic paste hook surfaces 63 are respectively fixed at the ends of the third fixing belts 61 far away from the arc-shaped supporting part 1. The second magic paste rough surface 62 is adhered to the corresponding second magic paste hook surface 63. In order to ensure that the arc-shaped supporting part 1 is better fixed to the leg 100 to ensure a good supporting and fixing effect, one ends of the two front second fixing belts 60 need to bypass the leg 100 and be located at the rear side of the leg 100. At this time, the second magic paste rough surface 62 faces upward. Then, one ends of the two rear third fixing belts 61 bypass the leg 100 and are located at the front side of the leg 100. At this time, the second magic paste hook surface 63 faces downward and fits with the corresponding second magic paste rough surface 62, so as to fix the arc-shaped supporting part 1 to the leg 100.
