Silica gel dressing film and production method thereof

Abstract

The invention belongs to the technical field of medical patch beauty materials, and particularly relates to a silica gel dressing film which comprises an upper layer and a lower layer, namely a self-adhering silica gel layer and an anti-adhering silica rubber layer which are integrated through high-temperature sulfurization. The produced corrugated silica gel dressing film has the outstanding advantages of being high in softness and compliance, so that the problem that the silica gel dressing film is liable to fall off when in use can be solved; the silica gel dressing film can be closely and seamlessly adhered to the body surface without being impacted by body movement, can be applied to the surface of a scar for a long time, can be prevented from falling off automatically, is more convenient to use, and is beneficial to improvement of the treating effect on hypertrophic scars.

Description

technical field [0001] The invention belongs to the technical field of medical patch cosmetic materials, in particular to a silicone gel dressing film and a manufacturing method thereof. Background technique [0002] After burns, trauma or surgery, scars will be formed on the patient's body surface. When the wound surface reaches the dermis, the scars formed by healing will appear hypertrophic scars or keloids, which not only affect the appearance and appearance, but also seriously cause the patient's activities. Function is impaired, and limb deformity may even be caused by scar hyperplasia or contracture. How to cure scars is still a difficult problem in world medicine. Since the 1980s, when the effect of silicone gel on scar softening was discovered, scholars from various countries have conducted a lot of research on the mechanism and clinical effect of silicone gel on scar softening. It was also reported in medical journals, proving that silicone gel can not only soften...

AI Technical Summary

Problems solved by technology

Compared with the first-generation silicone gel film, the second-generation silicone gel film has a longer application time in clinical use, but it will fall off on its own after a long time or when the limbs move

The reason is: the so-called dermatoglyphs are not dermatoglyphs, but the dermatoglyph design is a disordered pattern, which cannot freely expand and contract with the expansion of the skin; At the same time, the silicone gel film will be cut according to the size of the scar area. Some of the cut silicone gel films are flat-shaped, and some are bar-shaped, which has nothing to do with the skin texture and affects the silicone The performance of the gel film stretching around with the skin, and its softness and conformability should also be reduced due to design defects, which affects the sticking effect of the product, making the effect of requiring the product to be tightly bonded to the body surface to be reduced and will fall off
