[0005] In the above-mentioned wound protection sleeve, the one-way inflation valve comprises an L-shaped air intake valve body made of elastic rubber material, the air intake valve body is provided with an air intake channel, the outer end of the air intake channel is connected to the outside of the annular airbag, the inner ends of the air intake valve body are gradually reduced inwards to form an elastic constriction, and an air supply seam is formed on the elastic constriction that can be opened to supply gas into the annular airbag when the air intake channel supplies air. The air supply seam is opened when supplying air, and the air supply seam is closed after stopping inflation, so as to effectively prevent gas leakage and ensure that the airbag maintains pressure.

[0006] In the above-mentioned wound protection sleeve, the air inlet valve body is arranged on the air inlet hole on the outer wall of the annular airbag, and the air inlet valve body is connected to the annular airbag as a whole by bonding or ultrasonic welding.

[0007] In the above-mentioned wound protection sleeve, a cap is provided on the outer end of the air inlet valve body, the cap is provided with an inner plug and an outer edge, an axial limit ring is formed between the inner plug and the air inlet passage, and the axial limit ring is arranged in the axial limit ring groove. The cap can prevent dust, bacteria or external pollution from entering the one-way valve, and keep the valve body clean; the cooperation of the axial limit ring and the axial limit ring groove ensures that the cap is accurately installed, and avoids exposure of the valve body or misoperation due to slippage.

[0008] In the above wound protection sleeve, the water-changing structure includes an annular water-changing paper, the outer wall of which is bonded to the inner wall of the protective film sleeve. The water-changing paper can be used to visually observe whether water has entered the wound, and can be replaced with a new one, thereby reducing the use cost.

The water absorption of the sponge further improves the waterproof property.

[0011] In the above wound protection sleeve, the outer end of the protective film sleeve is connected to the inner end of the annular airbag as a whole. The protective film sleeve and the airbag are seamlessly connected to avoid gaps at the connection, reduce the risk of bacteria or liquid infiltration, and improve the firmness of the structure.

[0012] In the wound protection sleeve, the inner diameter of the annular airbag is smaller than the minimum inner diameter of the protective film sleeve. After inflation, the airbag can fit the skin more closely and provide a stable fixing force, while the loose design of the middle part of the protective film sleeve allows slight movement of the skin around the wound, improving comfort.

[0013] In the above wound protection sleeve, the inner wall of the annular airbag is provided with a plurality of wavy anti-skid patterns extending axially and arranged circumferentially, which increase the friction between the annular airbag and the skin, prevent the annular airbag from sliding when the limbs move or move, and ensure that the protection sleeve is always in the correct position.
