Description

Technical Field

[0001] This utility model relates to the field of knee brace technology, and in particular to a flat knitting cold and hot knee brace. Background Technology

[0002] The knee joint, as a key weight-bearing and mobility component of the human body, is prone to pain and swelling due to sports injuries, overuse, or arthritis. Hot and cold compresses are commonly used physical interventions in clinical practice. Cold compresses constrict blood vessels to reduce inflammation, while hot compresses promote blood circulation and relieve muscle stiffness. Traditional knee braces typically have built-in hot and cold compress packs of a fixed shape, but these have the following problems:

[0003] There are significant individual differences in the shape of the kneecap and the distribution of surrounding soft tissues. Most existing knee brace packs are rectangular or circular structures of a single size. For different users' knees, especially for patients with large patella or significant swelling around the patella, the fixed-size pack cannot cover the key pain areas, resulting in reduced efficacy. Utility Model Content

[0004] The purpose of this invention is to provide a flat knitted knee brace that can flexibly adjust the coverage area according to the individual's knee shape, ensuring that key pain areas are fully covered and improving the therapeutic effect of hot and cold compresses.

[0005] To achieve the above-mentioned objectives, the following technical solution is adopted for the flat knitting cold and hot knee pads of this utility model:

[0006] A flat knitted knee brace with hot and cold compresses includes a knee brace sleeve with a first and a second hot and cold compress pack inside. The first hot and cold compress pack is positioned on the front surface of the kneecap corresponding to the kneecap. Two second hot and cold compress packs are provided, one on each side of the knee joint. The first hot and cold compress pack includes a central compress pack, an extension compress pack, and a connecting component. Multiple extension compress packs are arranged circumferentially along the central compress pack, and the multiple extension compress packs are used to extend and cover the area around the knee. The connecting component connects and detaches the central compress pack and the extension compress packs.

[0007] Preferably, the edge of the central dressing is provided with a first edging, and the edge of the extended dressing is provided with a second edging; the connecting component includes a first connecting piece and a second connecting piece disposed on the second edging; one end of the first connecting piece is connected to the second edging, and the other end of the first connecting piece is provided with a first insert; one end of the second connecting piece is connected to the second edging, and the other end of the second connecting piece is provided with a second insert; the first edging has a plurality of circular holes, and the circular holes are connected to slits extending radially to the edge of the first edging; the first insert includes a first post, and the two ends of the first post are respectively provided with first limiting pieces, the diameter of the first limiting pieces being larger than the diameter of the circular holes; the second insert includes a second post, and the two ends of the second post are respectively provided with second limiting pieces, the diameter of the second limiting pieces being larger than the diameter of the circular holes; the first post or the second post is pressed into the circular holes through the slits; the first connecting piece is connected to one of the first limiting pieces, and the connection point between the first connecting piece and the first limiting piece is located on one side of the first edging; the second connecting piece is connected to one of the second limiting pieces, and the connection point between the second connecting piece and the second limiting piece is located on the other side of the second edging. The connection method of this utility model is to press the first or second insert into the round hole through the cut. Under the action of the first or second limiting hole, the first and second inserts will not be separated from the round hole. Moreover, the first connecting piece and the second connecting piece are respectively fixed on the front and back of the first edge to form a force couple balance and improve the torque bearing capacity.

[0008] Preferably, the central applicator has a pressing edge that presses its two sides together. The pressing edge is configured as a C-shaped structure, and two pressing edges are provided. The ends of the two pressing edges are arranged facing each other to form a flow gap. Two C-shaped pressing edges are used to press the two sides of the central dressing together, forming a flow gap at the ends. This structure divides the interior of the central dressing into a central hot and cold zone and an annular hot and cold zone. The dressing in the central hot and cold zone is thinner, while the dressing in the annular cooling zone is thicker. The central hot and cold zone corresponds to the center of the kneecap and has less dressing to avoid compressing the patella and causing discomfort. The annular hot and cold zone has more dressing, densely covering the muscles and ligaments around the patella, increasing heat capacity. Furthermore, during knee flexion and extension, the dressing in the central hot and cold zone reduces frictional resistance to the patella, while the dressing in the annular hot and cold zone generates micro-flow through the flow gap, continuously compensating for heat conduction loss caused by skin deformation and maintaining temperature stability. At the same time, the dressing in the annular hot and cold zone targets high-incidence areas of inflammation around the knee, such as the patellar ligament and pes anserine, and combined with the air-retaining design of the central hot and cold zone, it avoids mechanical stimulation for patients with chondromalacia patellae while ensuring that swollen areas receive sufficient hot and cold therapy penetration.

[0009] Preferably, the outline of the central dressing is set as a polygonal structure that is wider at the top and narrower at the bottom.

[0010] Preferably, the second hot and cold compress pack is configured as a long strip that is wide at both ends and narrow in the middle.

[0011] Preferably, the knee brace has a first storage bag and a second storage bag inside. The first storage bag is used to hold a first hot and cold compress pack, and the second storage bag is used to hold a second hot and cold compress pack.

[0012] Preferably, the first storage bag has a first opening, through which the first hot and cold compress pack is inserted into the first storage bag; the second storage bag has a second opening, through which the second hot and cold compress pack is inserted into the second storage bag.

[0013] Preferably, the interior of the first storage bag has multiple Velcro straps along its circumference, and the two sides of the first storage bag are glued together at the locations of the Velcro straps. A second gap is left between the Velcro straps and the edge of the first storage bag, and the central storage area formed by the multiple Velcro straps is adapted to the central dressing. The Velcro straps include a hook side and a loop side that adhere to each other; the hook side is located on one side of the interior of the first storage bag, and the loop side is located on the other side. If the central dressing can cover the knee, there is no need to assemble the extension dressing; simply insert the central dressing into the first storage bag through the first opening. At this time, the hook and loop sides of the Velcro straps adhere, thereby limiting the movement of the central dressing within the first storage bag.

[0014] Preferably, the interior of the central dressing, the extended dressing, and the second hot and cold dressing are all filled with a dressing, which is a hot and cold gel.

[0015] Preferably, the knee pad is formed by flat knitting.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention utilizes a detachable expandable first hot and cold compress pack design to achieve a modular splicing structure between the expandable pack and the intermediate pack. This allows users to flexibly adjust the coverage area according to their individual knee shape, ensuring that key pain areas are fully covered and significantly improving the therapeutic effect of hot and cold compresses.

[0035] The specific working process and principle of this utility model are as follows: First, depending on the individual's knee shape, it is selected whether to assemble the first hot and cold compress pack 5. If the central compress pack 501 cannot cover the knee, the extended compress pack 502 is spliced ​​with the central compress pack 501 through the connecting component. The extended compress pack 502 can be freely combined according to the location of knee pain, such as applying more to the upper side and less to the lower side. During splicing, the first insert 502d and the second insert 502g are pressed into the round hole 501c of the first edge pack 501b through the cut 501d to form a modular compress covering the anterior surface and surrounding area of ​​the kneecap. At this time, the assembled first hot and cold compress pack 5 can be inserted into the first storage bag 2 through the first opening 201. Specifically, when all the extended compress packs are spliced, such as... Figure 4 As shown, the hook and loop sides of all the Velcro 202 do not touch, and the edge of the extension pouch 502 is attached to the edge of the first storage pocket 2; when the extension pouch 502 is partially spliced, as... Figure 13-14 As shown, the rough and hook sides of some of the Velcro 202 are bonded together, thereby limiting the edge of the central dressing 501.

[0036] If the central dressing 501 can cover the knee, there is no need to assemble the extended dressing 502, such as Figure 12 As shown, simply insert the central dressing 501 into the first storage bag 2 through the first opening 201. At this time, the rough side and hook side of the Velcro 202 are bonded together, thereby restricting the movement of the central dressing 501 within the first storage bag 2.

[0037] Finally, place the second hot and cold compress pack 4 into the second storage bag 3; after the first hot and cold compress pack 5 and the second hot and cold compress pack 4 are installed, the knee brace 1 can be worn. The first hot and cold compress pack 5 corresponds to the position of the front surface of the kneecap, and the second hot and cold compress pack 4 corresponds to the position of both sides of the knee joint. Combined with the knee brace 1 woven by the horizontal knitting machine, it provides elastic restraint, realizes the directional conduction and dynamic adaptation of hot and cold heat, and achieves the therapeutic effect of inhibiting inflammation or relieving stiffness.
