Description

Modified chitin colloid dressing plaster

Technical Field

The utility model relates to a modified chitin colloid dressing subsides especially relate to a medical hydrocolloid surface of a wound dressing subsides that is used for facial burn nursing, belong to the medical dressing field among the medical instrument.

Background

At present, the treatment and nursing of the surface of a wound are mainly carried out by applying ointment, saline wet dressing and other modes aiming at the face burn, the original ointment is scraped off when the ointment is applied for the second dressing change, and then new ointment is applied, so that the pain of a patient is greatly increased; saline wet compress needs frequent change, increases medical personnel's work load. Meanwhile, the wound surface can be damaged by frequently changing the dressing, and secondary harm is brought to patients.

The hydrocolloid dressing is a new wound surface nursing medical dressing, is not adhered to the wound surface on the basis of a wet healing theory, is painless in dressing change, protects new tissues and avoids secondary damage of the wound surface; can accelerate wound healing, inhibit scar formation, and reduce pigmentation. However, the current medical hydrocolloid material is not designed into a special product according to the shape of the face and the concave-convex structure; in addition, because hydrocolloid's is relatively poor in the nature of pasting, can not cover facial wound completely, need medical personnel to cut the concatenation, complex operation, and cut that concatenation seam department skin recovery state has the difference, influences patient's quality after healing.

SUMMERY OF THE UTILITY MODEL

For satisfying the burn shape requirement of various positions of human face, accelerate healing time, improve the quality after healing, alleviate patient's misery, the utility model provides a modified chitin colloid dressing subsides as medical hydrocolloid burn facial mask, satisfies the burn shape requirement of various positions of human face, easy operation, change dressings painlessly, shorten healing time, restrain the scar formation, reduce the pigmentation, improve the quality after healing, alleviate patient's misery.

A modified chitin colloid dressing plaster comprises sequentially adhered release paper, a colloid layer, a PE film and an elastic film for adapting to various facial wound types; the colloid layer comprises a non-woven fabric and a modified chitin biomaterial colloid attached to the non-woven fabric, and the modified chitin biomaterial colloid contacts and covers the wound surface when in use.

The modified chitin colloid dressing plaster provided by the technical scheme of the utility model has the outermost layer of the elastic membrane, thus meeting the shape requirements of various parts of the human face, being simple to operate, painless in dressing change, accelerating the healing time, improving the quality after healing and relieving the pain of patients; on the other hand, the PE film can prevent bacteria from invading, maintain the temperature and the humidity of the wound surface, and change the original dry healing by utilizing the wet closure to treat the facial burn; the modified chitin biomaterial colloid makes the wound surface not easy to dehydrate and scab in the healing process, is beneficial to epithelial cell crawling, increases bioactive substances and improves the healing speed. The elastic membrane is pressed to ensure that no scar or color sediment is formed.

fig. 2 is a schematic structural view of the modified chitin colloid dressing patch of the present invention.

Detailed Description

The invention will be further described with reference to the accompanying drawings and preferred embodiments.

The specific embodiment of the utility model provides a modified chitin colloid dressing plaster, as shown in fig. 2, comprising a barrier paper 1, a colloid layer 2, a PE film 3 and an elastic film 4 for adapting to various facial wound types, which are sequentially attached; the colloid layer 2 comprises a non-woven fabric and a modified chitin biomaterial colloid attached to the non-woven fabric, and the modified chitin biomaterial colloid contacts and covers the wound surface when in use. When in use, the isolation paper 1 is firstly taken off, and the modified chitin biomaterial colloid of the colloid layer 2 is directly contacted with the skin to cover the wound surface. In order to be more stable when the elastic membrane is used at uneven wound parts, pressure-sensitive adhesive is attached to the edge of the elastic membrane 4 for fixing. The thickness of the colloid layer 2 is 1-1.5 mm; the thickness of the PE film 3 is 0.1-0.5 mm. The modified chitin biomaterial colloid of the utility model consists of modified chitin with deacetylation degree more than 90 percent and purified water. The utility model discloses when using, take off earlier barrier paper 1, make the colloid of colloid layer 2 cover the wound face and paste and go, the stretch film is located outmost.

Preferably, the shape of the modified chitin colloid dressing patch of the utility model is adapted to the face of human body, as shown in figure 1, and has openings at the eyes, nostrils and mouth; and may even extend to the neck. The dressing paste can be a whole piece, or two pieces spliced from left to right or two pieces spliced from top to bottom.

The foregoing is a more detailed description of the present invention, taken in conjunction with the specific preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments shown and described. To the technical field of the utility model belongs to the prerequisite of not deviating from the utility model discloses, can also make a plurality of equal substitution or obvious variants, performance or usage are the same moreover, all should regard as belonging to the utility model's scope of protection.
