DETAILED DESCRIPTION

[0022] The embodiments of the utility model are described in detail below, examples of the embodiments are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the embodiments of the utility model, but cannot be understood as a limitation of the utility model.

[0023] As Figure 1 shown, the utility model discloses a lower limb lifting air cushion, including the bottom plate, the bottom plate is by first sub-board 1 and the second sub-board 2 of sliding connection with it are formed. Be equipped with the first air cushion 3 on the first sub-board 1, and be equipped with the second air cushion 5 that is connected with the first air cushion 3 through the air pipe 4 on the second sub-board 2. The first air cushion 3 is configured with inflation pipe 6, and the inflation pipe 6 is embedded with one-way valve. Inflation pipe 6 can be connected with inflation equipment, so that the first air cushion 3 and the second air cushion 5 are inflated. Since the first air cushion 3 and the second air cushion 5 are communicated with each other through the air pipe 4, only one inflation pipe 6 is needed, and the number of air pipes 4 can be set according to demand, and in the embodiment, the air pipe 4 is provided with two, to improve the inflation efficiency of the second air cushion 5. The first sub-board 1 and the second sub-board 2 are connected through the connecting plate 7, one end of the connecting plate 7 is slidably connected with the first air cushion 3, and the other end is rotatably connected with the second sub-board 2. A connecting groove, into which the connecting plate 7 can be slidably inserted, is arranged on the side of the first sub-board 1 close to the second sub-board 2, and a locking device for locking and fixing the connecting rod 16 is arranged on the side wall of the first sub-board 1. In the embodiment, the locking device mainly adopts locking screws, and two locking screws are arranged on the two sides of the first sub-board 1. By sliding the connecting plate 7 in the connecting groove, the distance between the first sub-board 1 and the second sub-board 2 can be adjusted. After the distance is adjusted, the locking screws are used for locking and fixing, so as to realize the adjustment of the width of the lifting air cushion (the adjustment range of the embodiment is a proper range), to meet the needs of different patients.

[0024] In the process of closely adhering the first sub-plate 1 and the second sub-plate 2, in order to prevent the air pipe 4 from being squeezed, a receiving groove 9 for accommodating the connecting pipe is designed on the side of the first air cushion 3 close to the second air cushion 5. In this way, the air pipe 4 is properly arranged in the receiving groove 9, ensuring the close adherence between the first air cushion 3 and the second air cushion 5, while avoiding improper compression of the air pipe 4.

[0025] In order to realize the constraint of the patient's legs on the air cushion, a sliding groove 10 is arranged on the first air cushion 3, and a limiting device for leg limiting is arranged in the sliding groove 10. The limiting device can constrain the patient's legs on the air cushion to the certain extent, and try to prevent the patient's feet from turning in or out. In the embodiment, the limiting device includes two vertical plates 11 arranged at intervals on the first sub-plate 1, a connecting shaft 12 arranged between the two vertical plates 11, and two sets of limiting components 13 slidingly arranged on the connecting shaft 12. The two limiting components 13 form a limiting groove therebetween, and a fixing device is arranged on the limiting component 13. The fixing device is used for fixing the limiting component 13 after adjustment. According to different needs of the thickness of the patient's legs, the limiting component 13 is slid to adjust the distance between the two limiting components 13, and then the width of the limiting groove is adjusted. When the limiting component 13 contacts with the leg, it has a certain friction force, which can constrain the patient's leg to keep it in the neutral position as much as possible.

[0026] As shown in Figure 2 In the embodiment, the fixing device includes a pressing plate 14 arranged at the bottom of the limiting component 13, a spring 15 arranged between the pressing plate 14 and the limiting component 13, a connecting rod 16 slidingly penetrating the limiting component 13, and a pull rod 17 connected with the connecting rod 16. The bottom end of the connecting rod 16 is connected with the pressing plate 14, and the top end is connected with the pull rod 17. The spring 15 exerts a force on the pressing plate 14, so that the pressing plate 14 abuts against the first sub-plate 1. Through the friction force between the pressing plate 14 and the first sub-plate 1, the position of the limiting component 13 is fixed. In addition, an anti-slip sheet or the like can be attached to the bottom of the pressing plate 14 to improve the fixing effect.

[0027] Working principle: The patient should first place the legs on the first air cushion 3 and the second air cushion 5, and then lift the pull rod 17. This will cause the pressing plate 14 to rise through the connecting rod 16, so as to separate the pressing plate 14 from the first sub-plate 1. While the pull rod 17 is kept in the lifted state, the limiting component 13 is moved to contact and clamp the patient's leg, so as to constrain and position the patient's leg. Through the friction force between the limiting component 13 and the leg, the patient's leg is kept in the neutral position as much as possible. The bottom surface height of the limiting groove is lower than the surface height of the second air cushion 5, so that the bottom surface of the patient's leg does not contact with the limiting component 13, avoiding the formation of pressure sores on the leg.

[0028] In order to realize further adjustment of the air cushion height, the bottom of the first sub-plate 1 is provided with a height adjusting device. The device is composed of two support plates 18, which are respectively arranged on the two sides of the first sub-plate 1 and are provided with a support rod 19 for connecting the two support plates 18. The support rod 19 is designed in a column shape to ensure good contact with the bottom surface. In addition, the two support plates 18 and the first sub-plate 1 are fixed by locking screws. When the air cushion height needs to be adjusted, the support rod 19 can be operated to rotate the support plates 18, thereby adjusting the air cushion height within a certain range. After adjustment is completed, the locking screw is used for fixation.

[0029] In order to prevent the patient from having foot drop, a baffle 20 is arranged on the side of the first sub-plate 1 away from the second sub-plate 2. The bottom of the baffle 20 is provided with a clamping rod 21, and the first sub-plate 1 is provided with a clamping groove which is detachably connected with the clamping rod 21. Through the contact of the patient's foot bottom with the baffle 20, foot drop can be effectively prevented. Through the cooperation between the clamping rod 21 and the clamping groove, the baffle 20 can be easily disassembled and assembled, which is convenient to use.

[0030] The above is only a preferred embodiment of the present application, and is not used to limit the present application. Any modification, equivalent replacement and improvement made on the basis of and within the scope of the present application shall be included in the protection scope of the present application.
