Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a pressure fixation device after skin grafting. Background Technology

[0002] Skin grafting involves taking a portion of healthy skin from the donor site to cover an area where scar tissue has been removed (the recipient site). The donor skin needs new blood vessels to supply the recipient site in order to survive. Generally, autologous skin grafts have a high success rate, but there is a possibility of graft failure. Furthermore, all skin grafts will leave a scar at the donor site.

[0003] Existing post-skin grafting pressure fixation devices still have some shortcomings. Most of them use bandages for pressure bandaging, which creates tension adhesion, causing tension blisters and skin damage in patients. They are also inconvenient to use. Therefore, we propose a post-skin grafting pressure fixation device. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 This utility model provides a technical solution: a pressure fixation device for post-skin grafting, including a heat dissipation layer 1 and a breathable layer 2. The surface of the heat dissipation layer 1 is provided with the breathable layer 2, and the breathable layer 2 and the heat dissipation layer 1 are fixedly connected. The surface of the breathable layer 2 is provided with an inner fixation layer 3, and the surface of the inner fixation layer 3 is provided with an airbag 4. The airbag 4 and the inner fixation layer 3 are fixed by adhesive. One end of the airbag 4 is provided with an inflation hole 5, and the other end of the airbag 4 is provided with an exhaust pipe 6. The exhaust pipe 6 and the airbag 4 are interconnected, and a vent valve 7 is provided on one side of the exhaust pipe 6.

[0019] In this embodiment, when using the post-skin graft pressure fixation device, the wound is first bandaged with gauze, and then the device is wrapped around the surface of the gauze. The air bladder 4 is inflated through the air inlet 5. When the air bladder 4 is inflated, it can press and fix the gauze. The air bladder 4 is a whole unit. When it compresses the skin, the pressure is distributed as a whole, which can protect the skin. In contrast, the bandage provides local compression and is more likely to damage the skin.

[0020] Specifically, an adhesive layer 8 is provided on one side of the heat dissipation layer 1, and the adhesive layer 8 is fixedly connected to the heat dissipation layer 1. A protective film 9 is provided on the surface of the adhesive layer 8.

[0021] In this embodiment, the adhesive layer 8 and protective film 9 can fix the airbag 4 and adhere it to the skin surface to prevent the airbag 4 from shifting, thus effectively improving stability. The fixing buckle 10 and fixing strap 11 provide convenience for fixing the device. Simply pass the fixing strap 11 through the fixing buckle 10 and fix it with Velcro 12. The outer fixing layer 13 is used to fix the surface of the airbag 4.
