Description
Technical Field
[0001] The utility model relates to the technical field of silver-containing dressings, in particular to a silver-containing dressing for preventing central venous catheter-related bloodstream infection in burn patients. Background Art
[0002] Wound healing refers to a series of pathological and physiological processes in which local tissues are repaired through regeneration, repair, and reconstruction after tissue loss caused by the action of wounding factors. It is essentially an inherent defensive adaptive response of the body to tissue cell damage caused by various harmful factors. This regeneration and repair is manifested in the recovery of lost tissue structure and can also restore its function to varying degrees. Most skin wounds can heal naturally, but when the skin is extensively or irreversibly damaged, it needs to be covered immediately with wound dressings or skin substitutes to help skin regeneration and repair. Hydrophilic fiber silver dressings contain silver ions, which can be used to treat burns. They can also serve as an effective barrier to prevent bacterial penetration, helping to reduce wound infection. Silver ions can inhibit bacterial growth.
[0003] The existing hydrophilic fiber silver-containing dressing generally needs to be matched with a foam dressing, that is, the four sides of the tape edge extend out to assist in sticking on the skin. The existing hydrophilic fiber silver-containing dressing has the following disadvantages: when used to treat large-area burns, several pieces of silver-containing dressings and foam dressings need to be used in combination, and the tape edge at the combination is difficult to handle. It is separated at the connection of the silver-containing dressing and is easy to poke the burn area of the burn patient, causing secondary damage. Utility Model Content

DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figure 1-Figure 4 The silver-containing dressing for preventing central venous catheter-related bloodstream infection in burn patients shown in the figure comprises a base cloth block 7, a silver-containing dressing sheet 14 is fixedly connected to the bottom of the base cloth block 7, base cloth strips 4 are connected to the four sides of the base cloth block 7 through cut dotted lines 6, base cloth corners 5 are connected to the base cloth strips 4 through cut dotted lines 6, adhesive layers 2 are connected to the bottom of the base cloth strips 4 and the base cloth corners 5, a connecting piece 9 is fixedly connected to the top of the base cloth block 7 through a plastic film sheet 8, and a plurality of suspended adhesive tape bodies 10 are fixedly connected to the edge of the connecting piece 9 in a circumferentially equidistant array. The silver-containing dressing for preventing central venous catheter-related bloodstream infection in burn patients disclosed in the utility model can be spliced into a desired area size according to needs, and the seams at the splicing are neat, the user is more comfortable, and the connection between the silver-containing dressing unit sheets can be strengthened by the suspended adhesive tape body 10, and the connection is stable and not easy to fall apart.
[0022] Further, an outer wall of the base cloth block 7 is connected to an outer packaging sheet 1, and the outer packaging sheet 1 is composed of two upper and lower sheets, and the two sheets are adhered to each other through a frame-shaped adhesive layer 2 at the edge, so as to facilitate the packaging of the silver-containing dressing; further, a first tearing auxiliary sheet 3 extending out is fixedly connected to one side of the outer wall of the outer packaging sheet 1, which can assist in quickly tearing the outer packaging sheet 1; further, a tape head 12 is provided at the end of the suspended tape body 10, and a second tearing auxiliary sheet 13 is fixedly connected to the tail of the tape head 12, which can assist in quickly tearing the tape head 12; Furthermore, the base fabric strip 4 and the base fabric corner 5 are connected to a second silicone oil backing paper 15 through an adhesive layer 2, which can prevent the base fabric strip 4 and the base fabric corner 5 from sticking together when not in use. The suspended tape body 10 is suspended and bent, and the adhesive layer 2 below is bonded with a first silicone oil backing paper 11. The end of the suspended tape body 10 is bonded to the top edge of the plastic film sheet 8 through a tape head 12, which fixes the suspended tape body 10 to prevent it from being entangled together.
