Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical protective technology, specifically to a novel knee brace. Background Technology
[0002] In cardiac operating rooms, where temperatures are typically low, nurses and doctors are prone to feeling cold during procedures, making knee warmth particularly important. Prolonged exposure to cold can cause discomfort and even exacerbate existing health problems such as joint pain or muscle stiffness. Furthermore, many healthcare workers are at risk of varicose veins, especially during prolonged standing or surgery. Therefore, existing products for keeping warm often lack sufficient insulation and effective varicose vein prevention. Existing knee braces also often fail to adequately cover the required area, resulting in poor effectiveness. Utility Model Content
[0003] The purpose of this invention is to provide a new type of knee brace to solve the problem that existing knee braces cannot simultaneously provide warmth and prevent varicose veins.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A novel knee brace includes: an insulating layer, an elastic layer, and a knee protection layer. The insulating layer is disposed on the outer layer of the elastic layer, and the elastic layer has a decreasing pressure distribution from the ankle to the thigh. The insulating layer has a cutout around the knee, and the edge of the cutout is sewn to the elastic layer. The knee protection layer is disposed at the knee and sewn to the elastic layer.
[0006] Preferably, the insulation layer is made of a fabric with elasticity.
[0007] Preferably, the knee brace also includes elastic bands at both ends, and both the insulation layer and the elastic layer are connected to the elastic bands.
[0008] Preferably, the elastic layer has multiple massage bumps distributed on the calf portion.
[0009] Preferably, the device further includes a heating assembly, which includes a heating wire and a power supply assembly. The power supply assembly is connected to the heating wire, and the heating wire forms a heating mesh and is disposed between the insulation layer and the elastic layer.
[0010] Preferably, the heating wire is arranged around the lower leg portion of the insulation layer.
[0011] Preferably, it further includes: a heating belt disposed outside the insulation layer, the heating belt being used to hold the chemical heating agent bag.
[0012] Preferably, there are two heating bands, one of which is located on the lower leg portion of the insulation layer, and the other is located on the thigh portion of the insulation layer.
[0013] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this utility model are:
[0014] This invention features an insulation layer, an elastic layer, and a knee protection layer. The insulation layer provides warmth, while the knee protection layer protects and warms the knees. Cutouts around the knee area facilitate movement. Furthermore, the elastic layer's elasticity decreases from the ankle to the thigh, helping to overcome gravity and promote venous blood flow back to the heart. By incorporating the insulation and knee protection layers, the knees are kept warm, and the elastic layer helps prevent varicose veins. Therefore, this knee brace combines warmth and varicose vein prevention. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.
[0021] This embodiment provides a novel knee brace, such as Figures 1-3 As shown, the system includes: an insulation layer 1, an elastic layer 2, and a knee protection layer 3. The insulation layer 1 is disposed on the outer layer of the elastic layer 2, and the elastic layer 2 has a decreasing pressure distribution from the ankle to the thigh. The insulation layer 1 has a cutout 4 around the knee, and the edge of the cutout 4 is sewn to the elastic layer 2. The knee protection layer 3 is disposed at the knee and sewn to the elastic layer 2. The insulation layer 1 provides insulation, the knee protection layer 3 protects and warms the knee, and the cutout 4 around the knee facilitates the user's movement. Furthermore, because the elasticity of the elastic layer 2 decreases from the ankle to the thigh, this decreasing pressure distribution from bottom to top helps overcome gravity and promotes venous blood return towards the heart.
[0022] In this embodiment, by providing a heat-insulating layer 1 and a knee protection layer 3, the user's knees can be kept warm. Furthermore, by providing an elastic layer 2, varicose veins can be prevented. The elastic layer 2 in this embodiment is made of the same material as varicose vein compression stockings in the prior art.
[0023] Furthermore, the insulation layer 1 is made of a fabric with elasticity, making it easy to slip over the legs. For example, the insulation layer 1 can be made of wool fabric.
[0024] Furthermore, it also includes elastic bands 5 at both ends of the knee brace, with both the insulation layer 1 and the elastic layer 2 connected to the elastic bands 5. By providing the elastic bands 5, the knee brace of this embodiment can be securely fitted around the user's ankle to mid-thigh.
[0025] Furthermore, the elastic layer 2 is provided with multiple massage bumps 6 distributed on the calf area. When medical staff walk or stand, muscle movement will cause the massage bumps 6 to exert a pressing effect on the calf muscles.
[0026] Furthermore, such as Figure 1 As shown, the knee brace in this embodiment also includes a heating component, which includes a heating wire 7 and a power supply component 8. The power supply component 8 is connected to the heating wire 7, and the heating wire 7 forms a heating mesh 9 and is disposed between the insulation layer 1 and the elastic layer 2. Specifically, the heating wire 7 is arranged around the lower leg portion of the insulation layer 1 to heat the lower leg portion. Specifically, the power supply component 8 for powering the heating wire in this embodiment adopts existing technology, only... Figure 1 The location of the power supply component 8 is indicated in the diagram, and its specific structure will not be described in detail here.
[0027] As alternative embodiments of heating methods, such as Figure 3As shown, the knee brace in this embodiment also includes a heating band 10, which is disposed outside the insulation layer 1 and is used to hold a chemical heating agent bag. In this embodiment, the chemical heating agent bag contains activated carbon and iron powder, and the heat released through the oxidation reaction heats the user's legs. The chemical heating agent bag in this embodiment can be directly replaced by heat patches in the prior art.
[0028] Furthermore, two heating bands 10 are provided, one of which is located on the lower leg portion of the insulation layer 1, and the other is located on the thigh portion of the insulation layer 1, thereby heating the thigh and lower leg portions of the user.
[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
