Description

Technical Field

[0001] This utility model relates to a dressing, specifically a medical detachable dressing, belonging to the technical field of medical cold compress equipment. Background Technology

[0002] Medical cold compress devices and cold compress pads are medical tools used to relieve pain, reduce swelling, and lower body temperature. They are widely used in postoperative recovery, sports injuries, arthritis, sprains, muscle strains, and other scenarios. Medical cold compress devices are professional medical tools that provide a continuous cold compress effect through refrigeration technology. They are usually used in hospitals, clinics, or home care. Cold compress pads are cold compress tools that come into direct contact with the skin. They are usually used in conjunction with cold compress devices, but can also be used alone. Cold compresses can reduce blood circulation, reduce inflammation, and have an analgesic effect. They are a commonly used adjunctive treatment method in healthcare.

[0003] Currently, most existing dressings use ice cubes or hard cooling plates inside for cooling during use. Using ice cubes or hard cooling plates not only results in poor fit and comfort, but also requires regular manual replacement of the cooling medium, making them inconvenient to use. To address these issues, we provide a removable medical dressing. Summary of the Invention

[0004] To address the aforementioned problems, this utility model provides a removable medical dressing to solve these problems. The specific technical solution is as follows: A removable medical dressing includes an inner liner, a heat-insulating layer, and a breathable, antibacterial, and non-slip mesh. The inner liner is made of silicone or TPU or other flexible materials. A removable two-way shut-off valve is installed inside the inner liner, protruding from the upper surface of the inner liner. Multiple sets of water baffles are installed inside the inner liner, with the water baffles isolating the main water inlet channel from the inner liner. Multiple sets of capillary channels are isolated between two sets of water baffles. The height of the capillary channel baffles can be designed to be mm, and the spacing can be designed to be mm, to reduce water storage and weight. The water baffles are isolated from the inner wall of the inner liner, with the main water inlet and outlet channels designed diagonally. The heat-insulating layer is located on the four outer sides and the upper surface of the inner liner, and the breathable, antibacterial, and non-slip mesh is located at the bottom of the inner liner.

[0005] Preferably, the top of the thermal insulation layer is provided with two sets of limiting bands, and the inside of the two sets of limiting bands is provided with elastic bands. The upper surface of the elastic bands is provided with a first hook and loop fastener, and the lower surface of the elastic bands is provided with a second hook and loop fastener.

[0006] Preferably, the bottom end of the breathable, antibacterial, and anti-slip mesh is provided with multiple sets of anti-slip soft rubber particles, which are made of soft rubber particles to increase friction and prevent them from falling off.

[0007] Preferably, the main unit water tank is located on one side of the inner tank, and a control panel is provided on the front of the main unit water tank.

[0008] Preferably, the output end of the main unit water tank is provided with an inlet pipe, and the inlet pipe is detachably connected to the inlet end of the two-way shut-off valve. The return end of the main unit water tank is provided with an outlet pipe, and the other end of the outlet pipe is detachably connected to the outlet end of the two-way shut-off valve. The inlet pipe and the outlet pipe are made of silicone or PU polyurethane material.

[0009] Preferably, the outer sides of the inlet pipe and the outlet pipe are provided with heat insulation sleeves, and the heat insulation sleeves are made of heat insulation cotton.

[0010] Compared with the prior art, the present invention has the following beneficial effects: This utility model incorporates components such as water separators and capillary channels. The cooling pad is constructed using a biomimetic, densely arranged capillary channel design. This biomimetic capillary design increases the heat exchange frequency and efficiency. Furthermore, the multiple capillary channels reduce internal pressure and prevent water blockage (even if individual channels are blocked, it does not affect water circulation), thus increasing reliability. The main inlet and outlet water channels are designed with diagonal inlet and outlet paths, ensuring that the water flow path length of each capillary channel is consistent. This guarantees the uniformity of the temperature of the heat-conducting liquid flowing through the entire pad, resulting in a good fit, comfort, lightweight design, and portability.

[0013] The present invention will now be further described with reference to the accompanying drawings.

[0014] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A removable medical dressing; The system includes an inner liner 1, a heat insulation layer 7, and a breathable, antibacterial, and non-slip mesh fabric 12. The inner liner 1 is made of silicone or TPU or other flexible materials. A removable two-way shut-off valve 2 is installed inside the inner liner 1, protruding from the upper surface of the inner liner 1. Multiple water baffles 4 are installed inside the inner liner 1, creating a main water inlet channel 3 between the water baffles 4 and the interior of the inner liner 1. Multiple capillary channels 5 are separated between two sets of water baffles 4. The height of the capillary channel 5 can be designed to be 2mm. The distance can be designed to be 8mm to reduce water storage and weight. The water separator 4 is isolated from the inner wall of the inner tank 1 to form the main return water channel 6. The water channels of the main inlet channel 3 and the main return water channel 6 are designed to have diagonal water inlet and outlet. The heat insulation layer 7 is set on the four outer sides and the upper surface of the inner tank 1. The breathable antibacterial and anti-slip mesh 12 is set at the bottom of the inner tank 1. The bottom of the breathable antibacterial and anti-slip mesh 12 is provided with multiple sets of anti-slip soft rubber particles 13. The anti-slip soft rubber particles 13 are made of soft rubber particles to increase friction and prevent them from falling off. The main unit water tank 14 is located on one side of the inner tank 1. The control panel 15 is provided on the front of the main unit water tank 14. The output end of the main unit water tank 14 is provided with an inlet pipe 16, and the inlet pipe 16 is detachably connected to the inlet end of the two-way shut-off valve 2. The return end of the main unit water tank 14 is provided with an outlet pipe 17, and the other end of the outlet pipe 17 is detachably connected to the outlet end of the two-way shut-off valve 2. The inlet pipe 16 and the outlet pipe 17 are made of silicone or PU polyurethane material. The outside of the inlet pipe 16 and the outlet pipe 17 is provided with a heat insulation sleeve 18, which is made of heat insulation cotton.

[0015] The entire pad is a thin cavity. The heat-conducting inner liner 1 is made of a soft membrane with a thickness of 0.5mm, which is resistant to high and low temperatures. The material can be silicone, TPU, etc. In the middle of the inner liner 1, there are several vertically arranged 2mm high soft water separators 4 to form capillary channels 5 that mimic capillaries, so as to achieve the purpose of soft fit, pressure resistance, uniform heat and efficient heat exchange. The interior of the cooling pad is composed of biomimetic densely arranged capillary channels 5 (the height of the capillary channel slats can be designed to be 2mm, and the spacing can be designed to be 8mm to reduce water storage and weight). The biomimetic capillary design and multiple capillary channels 5 can increase the heat exchange frequency and improve the heat exchange efficiency. In addition, multiple capillary channels 5 can reduce the internal pressure of the pad and prevent water blockage (the water circulation is not affected even if individual channels are blocked by pressure). This increases reliability. The main inlet channel 3 and the main return channel 6 are designed to have diagonal inlet and outlet. The inlet port of the two-way shut-off valve 2 faces the direction of the main inlet channel 3, and the outlet port faces the direction of the main return channel 6, thereby ensuring that the water flow path length of each capillary channel 5 is consistent and ensuring the temperature uniformity of the heat-conducting liquid flowing through the entire water pad. The design employs multiple capillary channels 5. In actual use, if the pressure on the patient's warm compress area is too high and some channels are blocked, other capillary channels 5 can still flow back, which can effectively prevent water blockage and ensure normal function. The capillary channels 5 are arranged vertically along the length of the inner liner 1, making it easy for the inner liner 1 to bend and cover the affected area. The two-way shut-off valve 2 has inlet and outlet ports for connecting the inlet pipe 16 and outlet pipe 17 (a flexible silicone tube), respectively. The main unit's water tank 14 is designed for both hot and cold applications, with a temperature range typically controlled between 10°C and 20°C. Specific temperatures may vary depending on product type, brand, and usage scenario. The primary function of a cooling pad is to provide localized cooling to relieve pain, swelling, or inflammation. Therefore, its temperature is usually lower than body temperature but not excessively low to avoid frostbite or discomfort. For medical cooling pads or specially designed cooling products, the temperature may be even lower, but is generally controlled at 0°C. The temperature should be between 10°C and 10°C. Avoid prolonged direct skin contact during use to prevent low-temperature damage. The required temperature liquid (pure, non-toxic, and highly safe) is pumped into the inner tank 1 through the main unit's water tank 14. After circulating within the inner tank 1, the liquid re-enters the outlet pipe 17 through the outlet port of the two-way shut-off valve 2. The circulated liquid can then re-enter the main unit's water tank 14 for cooling or heating. The main unit's water tank 14 controls the liquid temperature through heat dissipation and circulation, thereby ensuring that the temperature of the internal components of the main unit remains within a controlled range. Within a safe range, to maintain a constant temperature, the inlet and outlet ports of the two-way shut-off valve 2 can be disconnected from the main unit's water tank 14 (inlet pipe 16 and outlet pipe 17), facilitating patient movement while wearing the dressing. The insulation sleeve 18 wrapped around the inlet pipe 16 and outlet pipe 17 reduces temperature loss. The inlet pipe 16 and outlet pipe 17 are two parallel pipes, wrapped with the insulation sleeve 18, resembling a single tube for ease of use. They are made of a soft material with a certain degree of pressure resistance to prevent collapse and blockage (such as PU polyurethane and silicone tubes). The two-way shut-off valve 2 is located in one corner of the inner liner 1 and is a quick-release two-way shut-off valve 2 (when disassembled, the water in the inner liner 1 and the inlet pipe 16 and outlet pipe 17 are all shut off and will not flow out; when reassembled, they can be connected in both directions), making it convenient for users to wear, replace and remove. To improve the effect of cold / hot compresses and increase comfort, an insulation layer 7 (such as insulation cotton, EVA foam, etc.) is added to the outside of the inner liner 1. The lower surface of the inner liner 1 (the surface in contact with the patient) is composed of a breathable, antibacterial and non-slip mesh fabric 12. Multiple sets of soft rubber anti-slip soft rubber particles 13 are distributed on the lower surface of the breathable, antibacterial and non-slip mesh fabric 12 to increase the friction of the pad and prevent it from falling off.

[0016] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A removable medical dressing; The top of the thermal insulation layer 7 is provided with two sets of safety limiting bands 8. The inside of the two sets of limiting bands 8 is detachably provided with elastic bands 9. The upper surface of the elastic bands 9 is provided with a first hook and loop fastener 10, and the lower surface of the elastic bands 9 is provided with a second hook and loop fastener 11.

[0017] The elastic band 9 is inserted inside the two sets of limiting bands 8. By stretching the elastic band 9 and attaching it with the first hook and loop fastener 10 and the second hook and loop fastener 11, the elastic band 9 allows the dressing to be wrapped around the patient's treatment area according to different locations (such as the shoulder, head, legs, etc.). When the dressing is not in use, the elastic band 9 inside one set of limiting bands 8 can be removed, and the dressing can be rolled up using the elastic band 9, the first hook and loop fastener 10 and the second hook and loop fastener 11 to secure the dressing after rolling it up, making it easy to store and carry.

[0018] The electrical equipment mentioned in this application are all common electrical equipment in the prior art. This application will not elaborate on their models or internal structures, and they can also be replaced by other power sources.
