Abstract
The invention relates to surgical dressings, and particularly relates to a surgical dressing containing chitin. The surgical dressing containing chitin comprises a non-woven fabric layer, a chitin layer and a pressure-sensitive adhesive layer, wherein the content of chitin in the chitin layer is 0.4g-0.8g in each square meter; the area of the chitin layer is less than that of the non-woven fabric layer, and is arranged on the non-woven fabric layer; the pressure-sensitive adhesive layer encloses the chitin layer and is arranged on the non-woven fabric layer. Compared with the prior art, the surgical dressing has advantages of traditional Chinese medicinal auxiliaries in the prior art, and has the advantages of favoring wound healing, preventing wound adhesive and facilitating releasing.
Description
Technical field
The present invention relates to a kind of medical dressing, especially a kind of medical dressing that contains chitin.
Background technology
In the prior art, relevant medical dressing is made up of non-woven fabrics, absorbent paper, cotton for wadding, leakproof film conventionally, and this paper medical dressing liquid absorption is large, and modification not after imbibition, does not produce fracture and reakdown phenomenon.If but this medical dressing during for baby, scald, burn patient, dressing is easy to and wound adhesion, is difficult for peeling off, and is not absorbed by tissue.
Summary of the invention
The object of the invention is to solve a prior art problem existing, the medical dressing that contains chitin of a kind of baby of being applicable to and scald, burn patient is provided.
For achieving the above object, the present invention adopts following technical scheme: a kind of medical dressing containing chitin, comprises nonwoven layer, chitin layer and pressure-sensitive adhesive layer, chitin content in described chitin layer (by every square meter) 0.4g-0.8g.Described chitin aspect is long-pending is less than nonwoven layer area, is arranged in nonwoven layer, and pressure-sensitive adhesive layer is arranged in nonwoven layer around chitin layer.
Preferably, chitin content (by every square meter) 0.6g in described chitin layer.
Preferably, also comprise off-style paper layer, described off-style paper layer covers nonwoven layer, and with pressure-sensitive adhesive layer laminating, described off-style paper layer is divided into two parts, overlapping on chitin layer.
Principle: chitin has the activity of anti-bacteria, fungus growth, is the natural antimicrobial substance that antimicrobial spectrum is wider, and gram positive bacteria, gram negative bacteria and Candida albicans are all had to obvious inhibition; Can promote the secretion of LYSOZYME, help wound healing; Chelating heavy metal; Chitin polymer with positive electric load and the erythrocyte surface cross-linking agent that exists very high static load bonding to form, can make blood form tampon and make blood coagulation; Chitin can also promote the migration of leukin and macrophage, promotes the healing of wound; Chitin derives from organism structure material, has very strong affinity with human body cell, and the enzyme in can body decomposes and absorbs, to human body avirulence and side effect; The positive charge of chitin can attract each other with the negative charge of macrophage and T lymphocytic cell surface, and excite these immunocytes to send generation instruction to B cell, and produce various immunoglobulins, thus the cellullar immunologic response of enhancing body and humoral immunoresponse(HI); Radioprotective; Because amino and the cellulose structure of chitin make it have extremely strong hydrophilic, wherein the unit charge of each chemical residue and the density of polar group are very large, impel the moisture-retaining capacity brilliance of chitin.
Compared with prior art, tool has the following advantages in the present invention: there is medical accessory in prior art, be conducive to the healing of wound simultaneously, and not can with wound adhesion, easily peel off.
Accompanying drawing explanation
Fig. 1 is the embodiment of the present invention 1 structural representation;
Fig. 2 is the embodiment of the present invention 2 structural representations.
The specific embodiment
Below in conjunction with accompanying drawing 1, the present invention is further described: a kind of medical dressing containing chitin, comprises nonwoven layer, chitin layer and pressure-sensitive adhesive layer, chitin content in described chitin layer (by every square meter) 0.4-0.8g; Described chitin aspect is long-pending is less than nonwoven layer area, is arranged in nonwoven layer, and pressure-sensitive adhesive layer is arranged in nonwoven layer around chitin layer; Also comprise off-style paper layer, described off-style paper layer covers nonwoven layer, fits with pressure-sensitive adhesive layer; Described off-style paper layer is divided into two parts, overlapping on chitin layer.
Embodiment 1: a kind of biological baby's navel paster, protects umbilicus pad 11 and thin polyurethane film base material 10 by medical pressure-sensitive adhesive 12, release paper 13, non-woven fabrics of chitin biology and makes for main raw material(s); Chitin content in described chitin layer (by every square meter) 0.4g.This product is mainly used in medical institutions or family is daily for neonate, the nursing of umbilical part and for health care when swimming and having a bath, the scratch of prevention umbilical part, infects.
Embodiment 2: a kind of biological wound dressing pastes, is made up for main raw material(s) of medical pressure-sensitive adhesive 22, release paper 23, the biological adsorptive pads 21 of non-woven fabrics of chitin and spun-laced nonwoven fabric or plastic film substrate 20; Chitin content in described chitin layer (by every square meter) 0.6g.The wound of protecting that this product is mainly used in medical institutions' clinical operation otch and body surface minor trauma mouth is used, prevent wound infection.
The present invention mainly applies the medical science pharmacology of chitin, on consumption, is controlled, and makes it infant and Wicresoft's wound reach better effect.The size of medical dressing of the present invention and shape are not restricted to size represented in accompanying drawing and shape, can set as required.
