[0018] For a further understanding of the purpose, structure, features and functions of the present invention, the following is a detailed description in conjunction with the embodiments.

[0019] Referring to Figure 1 as shown, Figure 1 Schematic diagram of a knee joint pressurizing device according to an embodiment of the present invention. The present invention provides a knee joint pressurizing device 100 for pressurizing the knee joint. The knee joint pressurizing device 100 includes a fitting portion 11, a first pressurizing portion 121, a second pressurizing portion 122, a first fixing portion 131 and a second fixing portion 132. The fitting portion 11 has a first long side 111, a first short side 112 and a first surface 113. The first long side 111 and the first short side 112 form the first surface 113. The first long side 111 has a first length L1, and the first short side 112 has a second length L2. The first length L1 is greater than the second length L2. The first pressurizing portion 121 is disposed on the first surface 113. The second pressurizing portion 122 is disposed on the first surface 113. The first pressurizing portion 121 and the second pressurizing portion 122 extend along the direction of the first long side 111, and the projections of the first pressurizing portion 121 and the second pressurizing portion 122 on the first long side 111 do not overlap and have a gap. The first fixing portion 131 is disposed on the first long side 111. The second fixing portion 132 is disposed on the first long side 111. Wherein, when the knee joint pressurizing device 100 is disposed on the knee joint, the first fixing portion 131 and the second fixing portion 132 are respectively fixed so that the fitting portion 11 adheres to the knee joint. The first pressurizing portion 121 is located on one side of the knee joint, and the second pressurizing portion 122 is located on the other side of the knee joint. In this way, stable pressurization can be achieved on the upper and lower parts of the knee joint through the two separated pressurizing portions.

[0020] Referring to Figure 1As shown, the fitting part 11 has a first long side 111, a first short side 112, a first surface 113, a second long side, a second short side and a second surface. The first long side 111, the first short side 112, the second long side and the second short side enclose the first surface 113 and the second surface, and the first surface 113 and the second surface are opposite to each other. In a specific implementation, the fitting part 11 is in a long strip shape. The first length L1 of the first long side 111 ranges from 40 cm to 50 cm. The first pressing part 121 and the second pressing part 122 are arranged on the first surface 113 of the fitting part 11 and are respectively located at both ends of the long side direction of the fitting part 11. When the knee joint pressing device 100 presses the knee joint, the first surface 113 of the fitting part 11 adheres to the knee joint and the second surface faces away from the knee joint, so that the first pressing part 121 and the second pressing part 122 have a better pressing effect on the knee joint.

[0021] Referring to Figure 1 As shown, the first pressing part 121 is circular. The first pressing part 121 is arranged at one end of the long side direction of the fitting part 11, and the first pressing part 121 adheres to one side of the knee joint. In a specific implementation, the first pressing part 121 has a first opening and closing part 141, a first accommodating space 142 and a first counterweight 143. The first opening and closing part 142 is located on one side of the first accommodating space 142, and the first counterweight 143 can be placed in the first accommodating space 142 through the first opening and closing part 141. The first opening and closing part 141 uses a zipper, and the first counterweight 143 uses a rice bag. When the knee joint pressing device 100 is in use, the zipper is opened to open the first accommodating space 142, and the rice bag is put into the first accommodating space 142. The weight of the rice bag can be adjusted according to the pressure value required by the patient's condition. The first opening and closing part 141 and the first counterweight 143 are not limited to the zipper and the rice bag, and it depends on the actual situation and is not limited thereto.

[0022] Referring to Figure 1As shown, the second pressing part 122 is circular. The second pressing part 122 is arranged at the other end of the long side direction of the fitting part 11, and the second pressing part 122 is attached to the other side of the knee joint. In specific implementation, the second pressing part 122 has a second opening and closing part 151, a second accommodation space 152 and a second counterweight 153. The second opening and closing part 152 is located on one side of the second accommodation space 152, and the second counterweight 153 can be placed in the second accommodation space 152 through the second opening and closing part 151. The second opening and closing part 151 uses a zipper, and the second counterweight 153 uses a rice bag. When the knee joint pressing device 100 is in use, the zipper is opened to open the second accommodation space 152, and the rice bag is placed in the second accommodation space 152. The weight of the rice bag can be adjusted according to the pressure value required by the patient's condition. The second opening and closing part 151 and the second counterweight 153 are not limited to the zipper and the rice bag, and are determined according to the actual situation, and are not limited thereto. In a better implementation manner, the weight of the first counterweight 143 is different from the weight of the second counterweight 144. When the first pressing part 121 is arranged on the upper side of the knee joint and the second pressing part 122 is arranged on the lower side of the knee joint, the weight of the first counterweight 143 is greater than the weight of the second counterweight 144 to make the pressing effect better and avoid excessive pressure on the lower side of the knee joint, which is not conducive to recovery.

[0023] Refer to Figure 1 As shown, the first fixing part 131 has elasticity. The first fixing part 131 is arranged at the upper part of the perpendicular bisector of the first long side 111 of the fitting part 11, and the first fixing part 131 is fixed to one side of the knee joint to fix the fitting part to the knee joint. In the direction of the first short side 112, the projection of the first fixing part 131 on the first pressing part 121 is partially covered by the first pressing part 121. In specific implementation, in the direction of the first short side 112, the midline of the first fixing part 131 basically coincides with the midline of the first pressing part 121. In this way, the first pressing part 121 after the first fixing part 131 is fixed presses the knee joint better.

[0024] Refer to Figure 1As shown, the second fixing part 132 is elastic. The second fixing part 132 is arranged at the lower part of the perpendicular bisector of the first long side 111 of the fitting part 11. The second fixing part 132 is fixed to the other side of the knee joint to fix the fitting part to the knee joint. In the direction of the first short side 112, the projection of the second fixing part 132 on the second pressing part 122 is partially covered by the second pressing part 122. Specifically, in the direction of the first short side 112, the midline of the second fixing part 132 basically coincides with the midline of the second pressing part 122. In this way, the second pressing part 122 after being fixed by the second fixing part 132 and the first pressing part 121 after being fixed by the first fixing part 131 can better press the knee joint. In a preferred embodiment, in the direction of the first long side 111, the first pressing part 121 has a first width W1, the second pressing part 122 has a second width W2, the first fixing part 13 has a third width W3, and the second fixing part 132 has a fourth width W4. The first width W1 is greater than the third width W3, and the second width W2 is greater than the fourth width W4. Among them, when the first width W1 is equal to the second width W2 and the third width W3 is equal to the fourth width W4, the upper and lower symmetric structure makes it unnecessary to specifically distinguish the pressing parts during use.

[0025] Refer to together Figure 2 As shown, Figure 2 is a schematic diagram of a knee joint pressing device according to another embodiment of the present invention. The knee joint pressing device 100 further includes a first connecting part 161 and a second connecting part 162.
