Description

Technical Field

[0001] This utility model relates to the field of medical supplies technology, specifically to a medical antibacterial surgical drape. Background Technology

[0002] A surgical drape is a surgical drape specifically designed for performing surgery on a patient at a particular site. This drape has holes pre-drilled for specific surgical locations, allowing the surgeon to perform the operation through these pre-designated holes.

[0003] Traditional surgical drapes are mostly made of polyethylene or spunbond nonwoven fabric, which have poor shape retention and are generally fixed by gravity or surgical tape. They are prone to loosening and slipping when the patient's position changes or during surgery, leading to contamination of the surgical field. Moreover, surgical drapes cannot conform to the curves of the human body and tend to form wrinkles in the depressions of the body surface. This causes intraoperative fluid to accumulate in the wrinkles, making it difficult to be absorbed or drained, increasing the risk of infection. Therefore, there are still shortcomings and deficiencies in the current technology. Utility Model Content

[0004] This invention provides a medical antibacterial surgical drape to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a medical antibacterial surgical drape, comprising a drape body, which includes, from the outside to the inside, a waterproof outer layer, an antibacterial layer, a shaping layer, and a skin-friendly inner layer. A first fixing strip is provided around the inner edge of the drape body, a surgical hole is provided in the middle of the drape body, a second fixing strip is provided around the surgical hole on the inner side of the drape body, and an annular absorbent part is provided around the surgical hole on the outer side of the drape body. The shaping layer includes a silicone filling layer, in which a memory metal mesh is embedded. The memory metal mesh can be bent and shaped along the curved surface of the patient's body to conform to the skin.

[0006] Preferably, the shape memory metal mesh adopts a nickel-titanium alloy mesh structure with a thickness of 0.1-0.3 mm.

[0007] Preferably, the skin-friendly inner layer surface is provided with micro-protrusions.

[0008] Preferably, the silicone filler layer has vent holes.

[0009] Preferably, the first and second fixing strips are made of medical pressure-sensitive adhesive layer, and the surface of the medical pressure-sensitive adhesive layer is coated with a nano-silver antibacterial film.

[0010] Preferably, the annular absorbent part is made of hydrophilic cotton.

[0011] The beneficial effects of this utility model are as follows: (1) This utility model uses a memory metal mesh to make the shaping layer flexible and have shaping force, which can conform to the curved surface of the patient's body and maintain its shape. Combined with the first fixing strip fixing the edge of the surgical drape and the second fixing strip fixing the surgical hole, a double anchoring is achieved, which can reduce the displacement of the surgical drape caused by the patient's movement or operation during the operation, and ensure the stability of the sterile area. In addition, the self-adaptive shaping ability of the memory metal mesh allows it to conform to the curved surface of the skin, reducing the wrinkles formed by the unevenness of the drape body, thereby avoiding the accumulation of liquid in the wrinkles and reducing infection. Risks; (2) By setting micro-protrusions, the actual contact area between the surgical drape and the skin is reduced, and by setting ventilating holes, water vapor evaporation is promoted, thereby reducing local heat accumulation on the skin, improving breathability, and enhancing the patient's comfort during the operation; (3) By setting nano-silver antibacterial film to cover the contact area between the first and second fixation strips and the skin, bacterial growth at the skin-strip interface can be reduced, thereby reducing the risk of postoperative infection; (4) Hydrophilic cotton can absorb blood, medication, rinsing fluid, etc. that overflow from the surgical hole, thereby improving the cleanliness of the surgical area and reducing the risk of contamination and cross-infection.

[0014] The present invention will now be further described with reference to the accompanying drawings.

[0015] like Figure 1-4As shown, this utility model provides a medical antibacterial surgical drape, including a drape body 1. The drape body 1 includes, from the outside to the inside, a waterproof outer layer 2, an antibacterial layer 3, a shaping layer 4, and a skin-friendly inner layer 5. The inner edge of the drape body 1 is provided with a first fixing strip 6. A surgical hole 7 is opened in the middle of the drape body 1. A second fixing strip 8 is provided around the surgical hole 7 on the inner side of the drape body 1. An annular absorbent part 9 is provided around the surgical hole 7 on the outer side of the drape body 1. The waterproof outer layer 2 is made of spunbond nonwoven fabric coated with a polyurethane (PU) waterproof coating. The antibacterial layer 3 is made of spunbond nonwoven fabric impregnated with chitosan antibacterial solution. The skin-friendly inner layer 5 is made of spunbond nonwoven fabric treated with hydrophobicity. The shaping layer 4 includes a silicone filling layer 41. The silicone filling layer 41 is embedded with a memory metal mesh 42. The memory metal mesh 42 can be bent and shaped along the patient's body surface to fit the skin.

[0016] Specifically, the surfaces of the first fixing strip 6 and the second fixing strip 8 are covered with peelable release paper. In use, firstly, remove the release paper from the second fixing strip 8, align the surgical hole 7 with the center of the surgical field, and gently press the second fixing strip 8 to initially adhere to the skin and fix the center of the surgical field. Next, apply appropriate pressure to cause the drape body 1, especially the shaping layer 4 and its internal memory metal mesh 42, to plastically deform and maintain its shape according to the patient's body surface curvature. Then, remove the release paper from the first fixing strip 6, smooth the drape body 1 from the center outwards, ensuring that the first fixing strip 6 adheres to the skin along its entire length. Finally, the surgery can be performed. Fluid overflowing during the procedure is absorbed by the annular absorbent part 9. After the surgery is completed, the surgical drape is slowly removed along the directions of the first fixing strip 6 and the second fixing strip 8 to avoid damaging the skin. This utility model uses the memory metal mesh 42 to make the shaping layer 4 flexible and shape-holding, which can conform to the patient's body surface and maintain its shape. Combined with the first fixing strip 6 fixing the edge of the surgical drape and the second fixing strip 8 fixing the surgical hole 7, a double anchoring is achieved, which can reduce the displacement of the surgical drape caused by the patient's movement or manipulation during the operation, and ensure the stability of the sterile area. In addition, the self-adaptive shaping ability of the memory metal mesh 42 allows it to conform to the skin surface, reducing wrinkles caused by unevenness of the drape body 1, thereby avoiding the accumulation of fluid in the wrinkles and reducing the risk of infection.

[0017] In some embodiments, the shape memory metal mesh 42 adopts a nickel-titanium alloy mesh structure with a thickness of 0.1-0.3 mm, which can balance good shaping and shaping ability with comfortable fit.

[0018] In some embodiments, the surface of the skin-friendly inner layer 5 is provided with micro-bumps 10, which are used to reduce the contact area between the surgical drape and the skin, thereby reducing local heat accumulation on the skin and improving the patient's comfort during the operation.

[0019] In some embodiments, the silicone filling layer 41 is provided with vent holes 11, which can promote water vapor evaporation, improve breathability, and enhance the patient's comfort during the surgical procedure.

[0020] In some embodiments, the first fixation strip 6 and the second fixation strip 8 are medical pressure-sensitive adhesive layers, and a nano-silver antibacterial film is laminated on the surface of the medical pressure-sensitive adhesive layer. The nano-silver antibacterial film covers the contact area between the first fixation strip 6, the second fixation strip 8 and the skin, thereby reducing bacterial growth at the skin-adhesive strip interface and reducing the risk of postoperative infection.

[0021] In some embodiments, the annular absorbent part 9 is made of hydrophilic cotton, which can absorb blood, medication, irrigation fluid, etc. that overflow from the surgical hole 7, thereby improving the cleanliness of the surgical procedure and reducing the risk of contamination and cross-infection.

[0022] The above embodiments can be combined with each other.

[0023] The above embodiments are not intended to limit the shape, material, structure, etc. of this utility model in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
