Description

Technical Field

[0001] The utility model relates to the technical field of ulcer patches, in particular to a novel foam dressing structure for preventing ulcers from occurring. Background Art

[0002] Ulcer is a common and frequently occurring disease in clinical practice. Currently, direct drug administration is the main method of treatment in clinical practice.

[0003] For example, the Chinese patent application, with publication number CN213642218U and titled "A Portable Ulcer Patch," includes a base layer, a medication pad, and a protective layer. The medication pad is disposed between the base layer and the protective layer. The base layer and the protective layer are connected as a single unit via a connecting portion, which is folded to allow the protective layer and the base layer to overlap. The base layer also includes an adhesive region for bonding the base layer and the protective layer. This invention configures the base layer and the protective layer into a single, overlapping, and adhesively bonded "bag-like" structure, isolating the medication pad from external contamination. Furthermore, the provision of an easy-tear portion allows for the appropriate number of ulcer patches to be removed as needed, while the removed patches remain individually sealed, making them easy to carry and clean.

[0004] For example, the announcement number is CN212699683U, and the name of the Chinese authorized patent is (A recombinant collagen ulcer patch), which includes: an ulcer patch body, the ulcer patch body is in the shape of a sheet with a high middle and low sides, the ulcer patch body is a layered structure in which each layer is adhesively bonded and hot-pressed into a whole, the layered structure of the ulcer patch body from top to bottom is a permeable membrane, a recombinant collagen matrix layer, and a waterproof isolation layer, and the recombinant collagen matrix layer is located in a protruding position in the middle of the ulcer patch body, and the outer edge of the outer surface of the permeable membrane is provided with an adhesive layer. The ulcer patch of this utility model has the recombinant collagen matrix layer protruding, so that the drug in the recombinant collagen matrix layer is directly aimed at the wound site and penetrates the permeable membrane directly to the affected area to exert its medicinal effect, which can have antibacterial and analgesic effects, help the ulcer surface to repair quickly, relieve the patient's pain, and greatly shorten the treatment cycle.

[0005] However, the existing ulcer patches have the problem of positional deviation of the internal medicine when they are used; therefore, they do not meet the existing needs. To this end, we have proposed a new foam dressing structure to prevent the occurrence of ulcers. Utility Model Content

[0013] Preferably, a breathable outer layer mechanism is provided on the inner side of the foam dressing patch body, and the breathable outer layer mechanism is hot-melt-connected to the inner side of the foam dressing patch body.

[0014] Preferably, an adhesive layer is provided on the inner side of the breathable inner layer structure, and the adhesive layer is connected to the inner side of the breathable inner layer structure by hot melt.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The utility model arranges an annular adhesive layer, a liquid absorption layer, a waterproof and antibacterial layer, an anti-adhesion wound contact layer and medicine inside the foam dressing material. The foam dressing material is installed in the reserved inner cavity of the breathable inner layer mechanism, and a circle of the outer wall of the foam dressing material is embedded and fixed in the reserved inner cavity of the breathable inner layer mechanism through the annular adhesive layer. The arranged liquid absorption layer and waterproof and antibacterial layer can effectively protect the medicine inside the patch when not in use, avoiding the problem of position deviation of the medicine inside the existing ulcer patch when in use.
