[0023] Reference Figure 1-2 The image shown is a preferred embodiment of the present invention.

[0024] A waterproof protective sleeve for limb wounds includes two end rings 10, which are arranged around each other to form an end area. An elastically deformable and annular membrane ring 20 is arranged in the end area. The membrane ring 20 has an outer peripheral ring on its outer side and an inner peripheral ring on its inner side. The inner peripheral ring surrounds and forms a hollow area 21, through which the user's limb can pass. The outer peripheral ring of the membrane ring 20 is fixedly connected to the end rings 10 and is arranged in a closed manner.

[0025] Two flexible waterproof membranes 30 arranged in a ring are provided between the two end rings 10. These are an outer membrane 32 and an inner membrane 31. The ends of the inner membrane 31 are fixedly connected to the two end rings 10, and the ends of the outer membrane 32 are fixedly connected to the two end rings 10. The inner membrane 31 surrounds and encloses to form a limb cavity 40. The outer membrane 32 is arranged outside the inner membrane 31 and forms an annular peripheral isolation cavity 33 between it and the inner membrane 31. The peripheral isolation cavity 33 surrounds the outer periphery of the limb cavity 40.

[0026] The aforementioned waterproof protective sleeve for limb wounds uses two membrane rings 20 for end sealing and fixation, and the outer membrane 32 and inner membrane 31 provide a double circumferential seal, thereby achieving a full-range seal of the limb cavity 40. This can waterproof the wound segment without compressing the wound, avoiding secondary damage. It is easy to operate and solves the problem of inadequate waterproof protection for patients' limb wounds.

[0027] When in use, the user's limbs pass through the hollow areas 21 of the two membrane rings 20 respectively. The inner circumferential ring is compressed and elastically stretched and deformed, and is bound to the outer circumference of the limb. The inner circumferential ring and the limb are arranged in a closed and fixed manner. The wound segment of the limb is located in the limb cavity 40, and the limb cavity 40 is in a sealed state at this time. The outer membrane 32 and the inner membrane 31 surround the outer circumference of the wound segment respectively.

[0028] In this way, the end is sealed and fixed by two membrane rings 20, and the outer membrane 32 and inner membrane 31 provide a double circumferential seal, thereby achieving a full-range seal of the limb cavity 40. This can waterproof the wound segment without compressing the wound, avoiding secondary damage to the wound, and the operation is simple.

[0029] The purpose of setting the outer membrane 32 here is that when there is a large temperature difference between the inside of the limb cavity 40 and the outside temperature, water droplets will form on the inside of the inner membrane 31, which greatly reduces the waterproof effect. The outer membrane 32 is arranged here to form a ring-shaped peripheral isolation cavity 33 between the limb cavity 40 and the outside, so as to prevent water droplets from forming on the inside of the inner membrane 31. Even if water droplets form, they will form on the inside of the outer membrane 32 and in the peripheral isolation cavity 33, and will not come into contact with the wound.

[0030] In this embodiment, the inner membrane 31 has an outward-facing surface facing the outer membrane 32, and an absorbent cotton layer 34 is provided on the outward-facing surface. The absorbent cotton layer 34 is located in the outer peripheral isolation cavity 33. In this way, the absorbent cotton layer 34 can absorb water droplets formed in the outer peripheral isolation cavity 33, keeping the outer peripheral isolation cavity 33 dry.

[0031] In this embodiment, the inner membrane 31 has an inward surface facing the limb cavity 40, and an antibacterial layer is provided on the inward surface. The antibacterial layer is located in the limb cavity 40. The antibacterial layer is a nano silver ion antibacterial layer with a thickness of 1-3 μm and a surface roughness Ra≤0.5 μm. This can inhibit bacterial growth, reduce the risk of wound infection, and reduce adhesion to the wound surface by a smooth surface.

[0032] In this embodiment, two membrane rings 20 arranged vertically are connected to the end ring 10.

[0033] After the limb passes through the two membrane rings 20, the two membrane rings 20 are staggered vertically and fixed to the limb, forming a closed end isolation cavity between the two membrane rings 20, which further achieves the effect of end sealing and waterproofing.

[0034] In this embodiment, an elastic strap 11 is provided on the outer side of the end ring 10, and a Velcro 12 is provided at the end of the strap. The surface of the strap is provided with anti-slip texture. In this way, the elastic strap 11 can achieve secondary fixation to prevent the end ring 10 from sliding and shifting, and the Velcro 12 is designed to facilitate adjustment of tightness.

[0035] In this embodiment, the two end rings 10 are the upper end ring 10 and the lower end ring 10, respectively. The lower end ring 10 is located below the upper end ring 10. A one-way drainage valve 13 is provided at the bottom of the lower end ring 10. The one-way drainage valve 13 is connected to a transparent liquid storage bag 14. The inner wall of the transparent liquid storage bag 14 is coated with an antibacterial layer. In this way, the accumulated liquid can be automatically drained through the one-way drainage valve 13 to prevent infection, and the transparent liquid storage bag 14 makes it easy to observe the liquid volume.

[0036] The basic structure of the one-way valve 13 includes main components such as the valve body, valve core, spring, and seals. The valve body, as the main structural component of the entire valve, primarily houses and secures other parts; the valve core is the key component controlling fluid flow and is typically made of materials such as PTFE; the spring controls the opening and closing of the valve core; and the seals provide a sealing function to ensure no fluid leakage. Furthermore, one-way valves are usually equipped with inlet and outlet ports so that fluid can flow in from the inlet and out from the outlet.

[0037] In this embodiment, the outer peripheral isolation cavity 33 is provided with multiple honeycomb-shaped support strips. The multiple support strips are arranged at intervals around the circumference of the outer peripheral isolation cavity 33. The two ends of the support strips are respectively connected to two end rings 10. The support strips are made of biodegradable polylactic acid material or rubber material. In this way, the stability of the outer peripheral isolation cavity 33 structure can be maintained, the membrane layer can be prevented from collapsing, and the biodegradable material is environmentally friendly and harmless.

[0038] In this embodiment, reflective strips 35 are provided on the outer surface of the outer film 32. The reflective strips 35 are distributed at intervals along the axial direction of the outer film 32, with a width of 5-8mm. The surface is provided with a prism reflection structure, which can enhance the safety of nighttime use. The reflection structure can increase the visibility distance to more than 50 meters.

[0039] In this embodiment, a transparent observation window 50 is provided on the outer side of the waterproof membrane 30, and a scale line is provided on the edge of the observation window. In this way, the wound healing status can be observed in real time through the transparent observation window 50, and the scale line can be used as an auxiliary measure to measure the area of ​​redness and swelling.

[0040] In this embodiment, an annular silicone anti-slip layer is provided on the inner side of the inner circumferential ring, and the surface of the silicone anti-slip layer is provided with spaced hemispherical protrusions 22. This enhances the contact friction between the end and the skin, further preventing water from seeping in from the edge of the hollow area 21 and improving the overall sealing performance.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
