Self-adhesive burn and scald dressing

Technical Field

The utility model relates to the technical field of medical dressing, in particular to a self-adhesive burn and scald dressing.

Background

The bacterial cellulose membrane dressing is mainly used for treating burn and scald wounds, and has good moisture retention and moisture absorption capacity, and good curative effects on first-degree and second-degree burn and scald wounds. However, because the dressing itself has the characteristics of no viscosity and a large amount of moisture, the dressing needs to be fixed on the outer layer in the using process, and the outer layer fixing materials used in the traditional method generally comprise two types, namely, the traditional dressing such as bandage, gauze and the like, and the acrylic pressure-sensitive adhesive application. Gauze bandages have good air permeability, the moisture of the bacterial cellulose membrane can quickly volatilize, the dressing change frequency is high, and the medical expense of patients can be increased. Acrylate pressure-sensitive adhesive is applied ointment or plaster and has better moisturizing function, but moisture in the bacterial cellulose dressing can soak the glue film of applying ointment or plaster, makes the glue film lose viscidity, also can appear changing the too fast problem of frequency, has increased medical personnel's work load to a great extent.

In the self-adhesive burn and scald dressing, the breathable film layer is a water-blocking and bacterium-blocking film.

In the self-adhesive burn and scald dressing, the breathable film layer is a medical PU film.

In the self-adhesive burn and scald dressing, the release film layer is a medical PE film.

In the self-adhesive burn and scald dressing, the bacterial cellulose membrane is an acetic acid bacteria reticular cellulose membrane.

The utility model discloses an useful part lies in:

the utility model applies the hydrocolloid layer to the burn and scald dressing, and has excellent adhesive force in both dry and wet states;

the utility model can stabilize the limit bacterial cellulose membrane and ensure the stability of the dressing by arranging the accommodating groove on the hydrocolloid layer;

the dressing of this structure is changed dressings conveniently, and is simple to use, and the loaded down with trivial details problem of changing dressings in the solution bacterial cellulose dressing use that can be fine has reduced medical personnel's work load to a certain extent simultaneously.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, a self-adhesive burn and scald dressing comprises: the hydrocolloid layer 2 is pasted on the breathable film layer 1 on one side of the hydrocolloid layer 2, is pasted on the bacterial cellulose film 3 on the other side of the hydrocolloid layer 2, and is covered on the release film layer 4 on the hydrocolloid layer 2 and the bacterial cellulose film 3.

The hydrocolloid layer 2 consists of: the hydrocolloid layer body 201 is arranged in the accommodating groove 202 on the hydrocolloid layer body 201; the bacterial cellulose membrane 3 is stuck in the containing groove 202; as a preference, the receiving recess 202 is located in the center of the hydrocolloid layer body 201. Due to the design, the middle part is thin and the periphery is thick, the middle part is thin and the bacterial cellulose membrane 3 layer is covered, the area of the bacterial cellulose membrane 3 is the same as that of the accommodating groove 202 in the middle of the hydrocolloid layer 2, the whole thickness of the dressing is reduced due to the structure, and the comfort level of a user is improved; the adhesiveness of the hydrocolloid can be increased at the thick periphery, so that the wound can not fall off even if the exudate is more; the single piece of the dressing made of the hydrocolloid adhesive can be used for 3 to 7 days generally.
