Description

Technical Field

[0001] This invention belongs to the technical field of cold compress equipment, specifically referring to a cold compress nursing belt for orthopedic care. Background Technology

[0002] Orthopedic cold compress bandages must have a continuous and stable low-temperature delivery capability. Key requirements include: precise and controllable temperature (typically between 5-15℃), a design that conforms to the body's curves, ease of use, and secure fixation. The product should support targeted localized cold compresses to prevent frostbite, and the material must be waterproof and antibacterial to suit the postoperative wound environment, effectively reducing swelling, pain, and inhibiting inflammatory responses.

[0003] The current shortcomings of orthopedic cold compress care are mainly concentrated in three aspects: First, traditional cold compress devices are prone to condensation due to temperature differences. This condensation can seep into the wound dressing, creating a damp environment and significantly increasing the risk of wound infection. Second, most products lack flexible size and shape adjustment functions, making them unsuitable for different anatomical sites. They are particularly inadequate for patients with swollen joints, resulting in poor fixation, uneven cold compress pressure, and severely affecting the cooling effect. Third, patients cannot easily adjust the temperature and time themselves, relying on frequent interventions by medical staff, which reduces the continuity of care and patient comfort. Summary of the Invention

[0004] In response to the above issues, and to overcome the problems of water vapor condensation on the surface of current cold compress nursing equipment, the inability to adjust the nursing area, and the inconvenience for patients to adjust it themselves, this invention provides a cold compress nursing belt for orthopedic care. A protective layer is set on the surface of the cold compress nursing equipment to reduce water vapor condensation, and the components of the protective layer can be rotated to allow patients to adjust the nursing area themselves, which helps to reduce the workload of medical staff.

[0005] The technical solution adopted by the present invention is as follows: The present invention provides a cold compress band for orthopedic care, including a bandage, a knee joint cold compress device, a water vapor condensation shielding device, a water inlet pipe and a water outlet pipe. The knee joint cold compress device is in contact with the human joint. The edge of the water vapor condensation shielding device is fixedly connected to the upper wall of the knee joint cold compress device. The water inlet pipe and the water outlet pipe are both fixedly connected to the knee joint cold compress device, and cold water is delivered through the water inlet pipe and the water outlet pipe. The bandage is fixedly set on the side wall of the knee joint cold compress device, and the knee joint cold compress device is fixed to the joint through the bandage.

[0006] Furthermore, the knee joint cooling device includes a knee joint wrapping layer, an extended cooling plate, an extended plate slot, an extended plate block, and an extended plate block slot. The knee joint wrapping layer is fixed in contact with the human joint. The extended plate slot is disposed within the knee joint wrapping layer. The extended cooling plate engages and slides within the extended plate slot. The extended plate block is fixedly disposed on the top wall of the extended cooling plate. The extended plate block slot is connected to the extended plate slot, and the extended plate block engages and slides within the extended plate block slot.

[0007] Furthermore, the knee joint wrapping layer is configured as an arc shape, and the arc of the extended cooling plate is the same as the arc of the knee joint wrapping layer.

[0008] Furthermore, the knee joint cold compress device also includes a first limiting clamping plate, a second limiting clamping plate, a first limiting plate slot, and a second limiting plate slot. The first limiting plate slot and the second limiting plate slot are respectively disposed on both sides of the extension plate slot. The first limiting clamping plate engages and slides on the first limiting plate slot, and the second limiting clamping plate engages and slides within the second limiting plate slot.

[0009] Furthermore, both the first and second limiting clamping plates are provided with circular protrusions, which are used to limit the movement distance of the extension plate block. The first limiting clamping plate is connected to the first limiting plate slot by a spring, and the second limiting clamping plate is also connected to the second limiting plate slot by a spring.

[0010] Furthermore, the top wall of the extension plate block is provided with an arc-shaped connecting paddle for adjusting the position of the extension cooling plate within the knee joint wrapping layer. The connecting paddle is relatively thin and slides within the gap between the knee joint cooling device and the waterproof vapor condensation shielding device.

[0011] Furthermore, the waterproof vapor condensation shielding device includes a central arc-shaped ring, an edge fixing ring, a middle limiting ring, an adjusting ring one, and an adjusting ring two. The edge fixing ring is fixedly mounted on the top wall of the knee joint wrapping layer. The adjusting ring two is concentric with the edge fixing ring and slides along the side wall of the edge fixing ring. The middle limiting ring is fixedly connected to the edge fixing ring by a connecting plate. The connecting plate connects the top walls of the edge fixing ring and the middle limiting ring and does not affect the sliding of the adjusting ring two in the gap between the edge fixing ring and the middle limiting ring. The adjusting ring one is slidably connected to the middle limiting ring, and the central arc-shaped ring is slidably connected to the adjusting ring one. The diameter of the adjusting ring two is larger than the diameter of the adjusting ring one.

[0012] Furthermore, the first limiting clamping plate is provided with a fixed column, the second limiting clamping plate is provided with a fixed column, and the knee joint wrapping layer is provided with a column sliding groove and a column sliding groove. The first column sliding groove is connected to the first limiting plate slot, and the second limiting plate slot is connected to the second column sliding groove. The first fixed column slides in the first column sliding groove, and the second fixed column slides in the second column sliding groove. The first column sliding groove and the second column sliding groove are not set at the same horizontal height.

[0013] Furthermore, the bottom wall of the first adjusting ring is provided with a first column fixing hole, and the bottom wall of the second adjusting ring is provided with a second column fixing hole.

[0014] Furthermore, the middle limiting ring has an annular retaining strip on its side wall, which engages and rotates the middle limiting ring with the first adjusting ring. The first adjusting ring and the second adjusting ring have semi-circular retaining strips on their side walls near the middle limiting ring.

[0015] Furthermore, the first adjusting ring has a triangular protrusion on its side wall near the middle limiting ring, and the second adjusting ring has a triangular protrusion on its side wall near the middle limiting ring. A limiting strip is provided in a groove on one side wall of the middle limiting ring to restrict the movement range of the triangular protrusion. A limiting strip is provided in a groove on the other side wall of the middle limiting ring. A movable lever is provided on the upper wall of the first limiting strip, and a movable lever is provided on the upper wall of the second limiting strip. A second movable lever is provided. The top wall of the intermediate limiting ring is provided with a lever groove 1 and a lever groove 2. The first movable lever slides on the first lever groove, and the second movable lever slides in the second lever groove. Both the first and second movable levers are connected to the intermediate limiting ring by springs. Dragging the first and second movable levers causes the first and second limiting strips to separate from the first and second triangular protrusions, respectively, so as not to affect the rotation operation of the first and second adjusting rings.

[0016] Furthermore, a small hole is provided at the center of the central arc-shaped ring for placing the inlet and outlet pipes. A vortex-shaped groove is provided on the bottom wall of the central arc-shaped ring, and a vortex groove block is provided on the top wall of the connecting lever. When the central arc-shaped ring is rotated, the vortex-shaped groove, the vortex groove block, and the extension plate groove work together to allow the extension plate block to slide along the extension plate groove during the operation of rotating the central arc-shaped ring.

[0017] Furthermore, the knee joint wrapping layer is provided with a water pipe that guides the flow of water. The water pipe is coiled inside the knee joint wrapping layer, avoiding the extension plate slot. The extension cooling plate is provided with a separate water pipe. The connection between the water pipe in the extension cooling plate and the inlet and outlet water pipes has a telescopic effect.

[0018] Furthermore, both the first and second limiting strips are provided with protrusions of a triangular prism structure to limit the movement distance of the first and second triangular protrusions.

[0019] Furthermore, the central arc-shaped ring, the edge fixing ring, the middle limiting ring, the first adjusting ring, and the second adjusting ring should preferably be made of inorganic materials such as plastic to avoid moisture contamination of the wound.

[0020] This solution provides a cold compress bandage for orthopedic care, which has the following beneficial effects:

[0021] (1) Effectively prevents water vapor condensation and reduces the risk of infection: By setting up a water vapor condensation blocking device, including a central arc-shaped ring, an edge fixing ring, and a middle limiting ring, a physical barrier is formed on the surface of the cold compress. This design can effectively block the direct contact between the low-temperature surface and the external humid air, greatly reducing the generation of condensation water and avoiding the problem of condensation water penetrating and wetting the wound dressing, thereby significantly reducing the risk of postoperative wound infection;

[0022] (2) The nursing area is flexible and adjustable to meet the needs of different patients: Through the unique combination of extended cold compress plate, extended plate slot and limiting clamping plate, the cold compress area can be flexibly adjusted. The user can drive the extended cold compress plate to slide out or retract by rotating the central arc ring, through the transmission of the vortex slot and the vortex slot block, so as to perfectly fit the joints (especially the swollen knee joints) of patients of different body types, ensuring the comprehensiveness and effectiveness of cold compress;

[0023] (3) Convenient operation and stable fixation, improving patient autonomy and comfort: The device integrates easy-to-operate adjustment rings and connecting levers, allowing patients to adjust the cold compress area and tightness themselves without relying on medical staff. At the same time, the limiting clamping plate and its protrusions and spring design can firmly lock the position of the extension plate block after adjustment, ensuring stability and safety during use, improving the continuity of care and the patient's comfort experience;

[0024] (4) This invention integrates multiple functions such as cold compress, waterproofing, area adjustment, and stable fixation into one efficient unit. The water channel design in each component, such as the knee joint wrapping layer, avoids moving parts. The adjustment mechanism and locking mechanism (such as the cooperation between the triangular protrusion and the limit strip) work together to ensure that the equipment can achieve complex functions while being compact, reliable in operation, and highly practical.

The water inlet pipe 4 and the water outlet pipe 5 are both fixedly connected to the knee joint cold compress device 2. The strap 1 is fixedly set on the side wall of the knee joint cold compress device 2.

[0042] The knee joint cooling device 2 includes a knee joint wrapping layer 6, an extension cooling plate 7, an extension plate slot 8, an extension plate block 9, and an extension plate block slot 10. The knee joint wrapping layer 6 is fixed in contact with the human joint. The extension plate slot 8 is set inside the knee joint wrapping layer 6. The extension cooling plate 7 is engaged and slid within the extension plate slot 8. The extension plate block 9 is fixedly set on the top wall of the extension cooling plate 7. The extension plate block slot 10 is connected to the extension plate slot 8. The extension plate block 9 is engaged and slid within the extension plate block slot 10.

[0043] The knee joint wrapping layer 6 is designed in an arc shape, and the arc of the extended cold compress plate 7 is the same as the arc of the knee joint wrapping layer 6.

[0044] The knee joint cold compress device 2 also includes a first limiting clamping plate 11, a second limiting clamping plate 12, a first limiting plate slot 13, and a second limiting plate slot 14. The first limiting plate slot 13 and the second limiting plate slot 14 are respectively disposed on both sides of the extension plate slot 8. The first limiting clamping plate 11 engages and slides on the first limiting plate slot 13, and the second limiting clamping plate 12 engages and slides within the second limiting plate slot 14.

[0045] Both the first limiting clamping plate 11 and the second limiting clamping plate 12 are provided with circular protrusions. The first limiting clamping plate 11 is connected to the first limiting plate slot 13 by a spring, and the second limiting clamping plate 12 is also connected to the second limiting plate slot 14 by a spring.

[0046] An arc-shaped connecting paddle 15 is provided on the top wall of the extension plate block 9, which is used to adjust the position of the extension cooling plate 7 inside the knee joint wrapping layer 6. The connecting paddle 15 slides in the gap between the knee joint cooling device 2 and the waterproof vapor condensation shielding device 3.

[0047] The waterproof condensation shielding device 3 includes a central arc-shaped ring 16, an edge fixing ring 17, a middle limiting ring 18, an adjusting ring 19, and an adjusting ring 20. The edge fixing ring 17 is fixedly mounted on the top wall of the knee joint wrapping layer 6. The adjusting ring 20 is concentric with the edge fixing ring 17 and slides along the side wall of the edge fixing ring 17. The middle limiting ring 18 is fixedly connected to the edge fixing ring 17 by a connecting plate. The connecting plate connects the top walls of the edge fixing ring 17 and the middle limiting ring 18. The adjusting ring 19 is slidably connected to the middle limiting ring 18. The central arc-shaped ring 16 is slidably connected to the adjusting ring 19.

[0048] The first limiting clamping plate 11 is provided with a fixed column 21, and the second limiting clamping plate 12 is provided with a fixed column 22. The knee joint wrapping layer 6 is provided with a column sliding groove 23 and a column sliding groove 24 respectively. The first column sliding groove 23 is connected to the first limiting plate slot 13, and the second limiting plate slot 24 is connected to the second column sliding groove 24. The first fixed column 21 slides in the first column sliding groove 23, and the second fixed column 22 slides in the second column sliding groove 24.

[0049] The bottom wall of the adjusting ring 19 is provided with a column fixing hole 25, and the bottom wall of the adjusting ring 20 is provided with a column fixing hole 26.

[0050] The middle limiting ring 18 has a ring-shaped retaining strip on its side wall. The retaining strip makes the middle limiting ring 18 engage and rotate with the adjusting ring 19. The adjusting ring 19 and the adjusting ring 20 have semi-circular retaining strips on their side walls near the middle limiting ring 18.

[0051] The adjusting ring 19 has a triangular protrusion 27 on its side wall near the middle limiting ring 18, and the adjusting ring 20 has a triangular protrusion 28 on its side wall near the middle limiting ring 18. A limiting strip 29 is provided in a groove on one side wall of the middle limiting ring 18, and a limiting strip 30 is provided in a groove on the other side wall of the middle limiting ring 18. A movable paddle 31 is provided on the upper wall of the limiting strip 29, and a movable paddle 32 is provided on the upper wall of the limiting strip 30. A paddle groove 33 and a paddle groove 34 are provided on the top wall of the middle limiting ring 18. The movable paddle 31 slides on the paddle groove 33, and the movable paddle 32 slides in the paddle groove 34. Both the movable paddle 31 and the movable paddle 32 are connected to the middle limiting ring 18 by springs.

[0052] A small hole is provided at the center of the central arc-shaped ring 16, a vortex-shaped groove 35 is provided on the bottom wall of the central arc-shaped ring 16, and a vortex groove block 36 is provided on the top wall of the connecting lever 15.

[0053] The knee joint wrapping layer 6 is equipped with a water pipe that guides the flow of water. The water pipe is coiled inside the knee joint wrapping layer 6, avoiding the extension plate slot 8. The extension cooling plate 7 is equipped with a separate water pipe, and the water pipe inside the extension cooling plate 7 is connected to the inlet pipe 4 and the outlet pipe 5.

[0054] Both limit strip 1 29 and limit strip 2 30 are provided with protrusions of triangular prism structure.

[0055] In practical use, the knee joint wrapping layer 6 is placed over the joint, and the knee joint wrapping layer 6 is fixed to the body with the strap 1. Cold water is injected into the knee joint wrapping layer 6 through the water inlet pipe 4 to lower the body temperature of the joint area. Then, the cold water that has been wrapped around the knee joint wrapping layer 6 is discharged from the water outlet pipe 5.

[0056] When the knee joint wrapping layer 6 alone cannot completely cover the joint surgery area, it is necessary to expand the area covered by the device on the joint, so that the extension cooling plate 7 can slide out from the extension plate slot 8, and achieve a large-area wrapping of the joint area with the cooperation of the knee joint wrapping layer 6 and the extension cooling plate 7.

[0057] When operating the extended cold compress plate 7, it is necessary to first separate the limiting clamping plate 11 and the limiting clamping plate 22 from the extension plate block 9. The adjusting ring 19 and the adjusting ring 20 can be rotated. The adjusting ring 19 rotates counterclockwise and the adjusting ring 20 rotates clockwise. The column fixing hole 25 at the bottom of the adjusting ring 19 fixes the limiting clamping plate 11, and the column fixing hole 26 at the bottom of the adjusting ring 20 fixes the fixing column 22. Therefore, when the adjusting ring 19 and the adjusting ring 20 are rotated, the fixing column 11 and the fixing column 22 will be moved, changing the horizontal position of the limiting clamping plate 11 and the limiting clamping plate 22, so that the extension plate block 9 can move freely.

[0058] When adjusting ring 19 and adjusting ring 20 rotate, the triangular protrusion 27 on the side wall of adjusting ring 19 comes into contact with the triangular protrusion on the limiting strip 29. When the limiting strip 29 comes into contact with the triangular protrusion 27, it causes adjusting ring 19 to rotate only in one direction. Adjusting ring 20 uses the same principle as adjusting ring 19 to ensure that the spatial position of limiting clamping plate 11 and limiting clamping plate 212 remains unchanged after adjustment.

[0059] Then, the rotating central arc ring 16, under the engaging connection between the vortex-shaped slot 35 and the vortex slot block 36, and the cooperation between the extension plate block 9 and the extension plate slot 8, causes the connecting paddle 15 to slide outward along the direction of the extension plate slot 8, thereby squeezing the extension cold compress plate 7 out of the extension plate slot 8.

[0060] Then, fix the extension plate block 9, and lift the movable lever 2 32 upward and the movable lever 1 31 downward respectively, so that the limiting lever 1 29 and the limiting lever 2 30 are separated from the triangular protrusion 1 27 and the triangular protrusion 2 28 respectively. Under the elastic action of the springs of the limiting clamping plate 1 11 and the limiting clamping plate 2 12, the adjusting ring 1 19 rotates clockwise and the adjusting ring 2 20 rotates counterclockwise. At this time, the position of the extension plate block 9 is fixed by the protrusions on the limiting clamping plate 1 11 and the limiting clamping plate 2 12.

[0061] During use, because the temperature of the joint area is lower than the room temperature, water vapor condenses on the surface of the waterproof water vapor blocking device 3. The water vapor can be wiped off directly to avoid water vapor wetting the knee joint wrapping layer 6 and causing joint bone infection.

[0062] It should be noted that, in this document, the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0063] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
