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

[0024] A sheath-type waterproof structure for limb wounds includes two membrane bags 10 and a fixing ring 20. The two membrane bags 10 are an inner membrane bag 11 and an outer membrane bag 12. The inner membrane bag 11 has an inner membrane cavity 13 and an inner membrane end with an inner membrane opening. The outer membrane bag 12 has an outer membrane end with an outer membrane cavity and an outer membrane opening.

[0025] A fixed ring 20 is arranged around to form a fixed area. An elastically deformable and annular membrane ring 30 is arranged in the fixed area. The outer side of the membrane ring 30 has an outer peripheral ring, and the inner side of the membrane ring 30 has an inner peripheral ring. The inner peripheral ring surrounds and forms a hollow area 31, through which the user's limbs can pass. The outer peripheral ring of the membrane ring 30 is fixedly connected to the end ring and is arranged in a closed manner.

[0026] The outer membrane end and the inner membrane end are respectively fixed on the fixing ring 20 and arranged around the circumference of the fixing ring 20; the inner membrane bag 11 is formed in the outer membrane cavity, and an isolation cavity 14 is formed between the outer membrane bag 12 and the inner membrane bag 11, the isolation cavity 14 being located in the outer membrane cavity.

[0027] The aforementioned waterproof structure for limb wounds uses a membrane ring 30 for end sealing and fixation, and a double membrane bag 10 nested structure to form a double waterproof barrier. The isolation cavity 14 buffers external pressure and prevents the wound from contacting contaminants, thereby achieving a full-range seal of the inner membrane cavity 13. This waterproofs the wound without compressing it, avoiding secondary damage. The structure is simple to operate and solves the problem of inadequate waterproof protection for patients' limb wounds.

[0028] During use, the user's limb passes through the hollow area 31 of the membrane ring 30. The inner circumferential ring is compressed and elastically stretched, 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 inner membrane cavity 13, and the inner membrane cavity 13 is in a sealed state at this time. The outer membrane bag 12 and the inner membrane bag 11 are respectively wrapped around the outer circumference of the wound segment. In this way, the end is sealed and fixed by the membrane ring 30, and the inner membrane bag 11 and the outer membrane bag 12 form a double seal for the wound segment, thereby achieving a full-range seal of the inner membrane cavity 13. This can waterproof the wound segment and will not compress the wound, avoiding secondary damage to the wound. The operation is simple.

[0029] The purpose of setting the outer membrane bag 12 here is that when there is a large temperature difference between the inner membrane cavity 13 and the external temperature, water droplets will form on the inner side of the inner membrane bag 11, which greatly reduces the waterproof effect. The outer membrane bag 12 is arranged here to form a ring-shaped isolation cavity 14 between the inner membrane cavity 13 and the outside, so as to prevent water droplets from forming on the inner side of the inner membrane bag 11. Even if water droplets form, they will form on the inner side of the outer membrane bag 12 and in the isolation cavity 14, and will not come into contact with the wound.

[0030] In this embodiment, the inner membrane bag 11 has an outward-facing surface facing the outer membrane bag 12, and an absorbent cotton layer 15 is provided on the outward-facing surface. The absorbent cotton layer 15 is located in the isolation cavity 14. In this way, the absorbent cotton layer 15 can absorb water droplets formed in the isolation cavity 14, keeping the isolation cavity 14 dry.

[0031] In this embodiment, the inner membrane bag 11 has an inner surface facing the inner membrane cavity 13, and an antibacterial layer is provided on the inner surface. 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, five recessed grooves 16 are formed on the inner membrane bag 11, and the recessed grooves 16 are exposed in the inner membrane cavity 13. An elastic layer covers the recessed grooves 16. In this way, the tips of the five fingers or the tips of the five toes can be inserted, avoiding the tips of the fingers or toes from pressing against the inner membrane bag 11 and puncturing the inner membrane bag 11. Moreover, the elastic layer can adapt to joint movement, reduce friction, and improve wearing comfort.

[0033] In this embodiment, the isolation cavity 14 is provided with multiple elastically deformable buffer rings 17. The multiple buffer rings 17 are arranged sequentially at intervals along the length direction of the isolation cavity 14, and the buffer rings 17 are fixedly connected to the inner side of the isolation cavity 14. In this way, the pressure distribution can be optimized, the impact resistance performance can be improved, the excessive local pressure can be avoided from affecting the wound, and the membrane can also be prevented from collapsing.

[0034] In this embodiment, the outer membrane bag 12 adopts a three-layer composite structure, including a substrate layer, a waterproof and breathable membrane, and a tear-resistant layer; in this way, the waterproofness, breathability, and mechanical strength can be comprehensively improved, and the service life of the product can be extended.

[0035] In this embodiment, two membrane rings 30 arranged vertically are connected to the fixing ring 20.

[0036] After the limb passes through the two membrane rings 30, the two membrane rings 30 are staggered vertically and fixed to the limb, forming a closed partition cavity between the two membrane rings 30, which further achieves the effect of sealing and waterproofing the end.

[0037] In this embodiment, the outer side of the fixing ring 20 is provided with an adjustable elastic strap 21, and the end of the elastic strap 21 is provided with a Velcro 22. In this way, secondary fixation can be achieved through the elastic strap 21 to prevent the fixing ring 20 from sliding and shifting, and the Velcro 22 is designed to facilitate adjustment of tightness.

[0038] In this embodiment, an anti-slip strip is provided on the inner side of the inner circumferential ring. The surface of the anti-slip strip has a wavy or serrated structure, which can enhance the contact friction between the end and the skin, further prevent water from seeping in from the opening edge, and improve the overall sealing performance.

[0039] In this embodiment, the fixing ring 20 is provided with a one-way ventilation valve 23, which only allows moisture to be discharged from the inside to the outside; in this way, the internal and external air pressure can be balanced, moisture can be discharged, and stuffiness can be avoided to prevent the wound from worsening.

[0040] The one-way vent valve 23 is mainly composed of a valve body, a valve cover, and a diaphragm. One end of the valve body is provided with a connector with a central through hole, and the other end is provided with a threaded hole to connect with the valve body. One or more diaphragms are placed in the valve body cavity. The valve cover is provided with a central through hole, one end of which is a connector, and the other end extends into the valve body cavity and is provided with a vent groove at its end. The diaphragm achieves one-way function under the action of airflow pressure.

[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.
