DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0027] The present application provides a knee joint limiting brace, which comprises a first brace 1 on the upper and lower sides, a second brace 2 rotatably connected to one side of the first brace 1 through a hinge, an adjusting and fitting assembly 3 arranged in the interiors of the first brace 1 and the second brace 2, the adjusting and fitting assembly 3 comprising a threaded rod 301 threaded on the outer surface of the second brace 2, the threaded rod 301 having a fitting plate 302 rotatably connected to one end thereof through a bearing seat, the fitting plate 302 and the inner side wall of the first brace 1 both being provided with air-permeable cotton pads 303, the inner side wall of the air-permeable cotton pad 303 and the outer surface of the fitting plate 302 both being fixedly installed with telescopic columns 304 on both sides thereof, recesses being formed in the inner side walls of the second brace 2, the telescopic columns 304 being arranged in the interiors of the recesses, connecting plates 305 being rotatably connected to the upper and lower surfaces of the second brace 2, insertion columns 306 being slidably connected to the surfaces of the connecting plates 305, limiting springs 307 being fixedly installed on the outer surfaces of the insertion columns 306, the limiting springs 307 being fixedly installed on the upper surfaces of the connecting plates 305, insertion holes 308 being formed in the upper and lower surfaces of the first brace 1, the insertion holes 308 being adapted to the insertion columns 306.

[0028] In use, the medical staff first places the first brace 1 and the breathable cotton pad 303 of the inner side wall on the surface of the patient's leg, so that the patient's leg overlaps the surface of the breathable cotton pad 303, and then rotates the second brace 2 through the hinge, so that the second brace 2 is closed with the first brace 1. During the rotation of the second brace 2, the insertion column 306 is pulled and the limiting spring 307 is deformed. After the closing is completed, the insertion column 306 is loosened, and the insertion column 306 moves through the restoring force of the limiting spring 307. The insertion column 306 is inserted into the inside of the insertion hole 308, so that the second brace 2 is closed with the first brace 1. Then rotate the threaded rod 301, so that the threaded rod 301 drives the clamping plate 302 to move downward. The clamping plate 302 moves stably under the guidance of the telescopic column 304. Adjust the distance between the clamping plate 302 and the surface of the patient's leg, so that the breathable cotton pad 303 on one side of the clamping plate 302 tightly abuts the upper surface of the patient's leg, so that the knee joint limiting brace can adapt to different sizes of legs, and the fitting degree of the knee joint limiting brace with the patient's leg is ensured, avoiding the knee joint limiting brace from falling off, and ensuring the safety of the patient during use.

[0029] In order to ensure the air permeability of the knee joint limiting brace, as shown in Figures 1 to 5 , the surfaces of the clamping plate 302, the first brace 1 and the second brace 2 are provided with air grooves 4, and the number of the air grooves 4 is several.

[0030] The clamping plate 302 is located on the side surface of the breathable cotton pad 303, and the breathable cotton pad 303 tightly abuts the skin of the patient's leg. The air grooves 4 on the surfaces of the clamping plate 302, the first brace 1 and the second brace 2 ensure the air circulation of the device and improve the skin comfort of the patient during use of the device.

[0031] In order to adjust the distance between the upper and lower braces, as shown in Figures 1-3 , the two side surfaces of the first brace 1 and the second brace 2 are connected with the telescopic plates 5 through screws. The inner plate surface of the telescopic plate 5 is provided with a threaded hole, and the outer surface of the telescopic plate 5 is threadedly connected with a limiting bolt, and the limiting bolt is matched with the threaded hole.

[0032] The length of the telescopic plate 5 can be stretched or contracted, and then the inner plate of the telescopic plate 5 is limited by the limiting bolt to fix the length of the telescopic plate 5, so as to adjust the distance between the upper and lower braces, and facilitate the device to adapt to the legs of different people.

[0033] In order to adjust the angle of the upper and lower braces, as shown in Figure 1 and Figure 2 , one end of every two telescopic plates 5 is connected with an adjustable chuck 6, the inner side wall of the adjustable chuck 6 is provided with a sponge block 7, and the surface of the two second braces 2 is fixedly installed with a connecting belt, one end of the connecting belt is fixedly connected with a knee protection cover 8.

[0034] The angle between the upper and lower telescopic plates 5 can be adjusted by the adjustable chuck 6. The telescopic plates 5 drive the brace to move, thereby adjusting the positions of the upper and lower braces so that the brace can adapt to the angle required by the patient's legs. The setting of the knee protection cover 8 can protect the patient's knees, avoid secondary damage to the knees caused by external forces, protect the patient's knees, and improve its practicality.

[0035] In order to improve the anti-slip property of the brace, Figures 1-3 As shown, the inner side wall of the breathable cotton pad 303 is provided with an anti-skid layer, the inner side wall of the anti-skid layer is provided with a plurality of anti-skid particles 11, and the surface of the anti-skid layer is provided with a plurality of air holes.

[0036] The anti-slip particles 11 arranged on the surface of the anti-slip layer make the anti-slip layer adhere closely to the patient's skin. The provision of the ventilation holes prevents the patient's legs from sweating, thus ensuring the anti-slip performance of the device after installation.

[0037] Extension straps 9 are fixedly mounted on both sides of the side surface of the first brace 1 , wherein a buckle 10 is fixedly mounted on one end of the extension strap 9 on one side, and the buckle 10 is adapted to the extension strap 9 on the other side.

[0038] The extension belt 9 is wrapped under the bed and limited by the buckle 10 on one side, so that the brace is fixed on the bed surface, forcibly braking the patient's legs, preventing the patient from moving their legs unconsciously, and ensuring the braking stability of the device.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
