CN203042642U - Water-soluble chitosan woundplast - Google Patents

Abstract

The utility model relates to a water-soluble chitosan woundplast which is composed of gluing cloth (1), a water absorption pad (2) and protective films (3). The water-soluble chitosan woundplast is characterized in that the water absorption pad (2) is arranged in the middle of the gluing cloth (1) and the protective films (3) are arranged on the gluing cloth (1) and the water absorption pad (2). The water-soluble chitosan woundplast has the advantages of being simple in structure, reasonable and practical in design, safe, sanitary and capable of replacing ordinary woundplast of a cotton fiber and chemical fiber water absorption pad and facilitating healing of a wound well and rapidly. The water-soluble chitosan woundplast is strong in bacteria resistance, capable of stopping bleeding instantly, strong in analgesia and capable of enabling the wound to heal fast, being absorbed completely without adhering to the wound and restricting generation of a scar.

Description

A kind of water-soluble chitosan adhesive bandage

Technical field

This utility model belongs to field of medical products, is specifically related to a kind of water-soluble chitosan adhesive bandage.

Background technology

At present; the adhesive bandage of domestic production all is medical adhesive tape (adhesive plaster); adsorptive pads (antiseptic gauze); release paper protects film three parts are formed; directly the part of contact wound is adsorptive pads; be also referred to as medicated core, be the core material of adhesive bandage, general adsorptive pads often uses cotton fiber cloth to make; a part is chemical fiber cloth; the last attached isolated film that has, purpose are for having prevented the adhesion wound, but the antibacterial action of existence own is poor; wound there is not analgesic activity; only rely on compression method hemostasis, can not quick-acting haemostatic powder, and the effect of anti wound is little; and the effect of unrestraint cicatrix, defectives such as wound healing time length.

Summary of the invention

For overcoming above-mentioned shortcoming; this utility model has been taked a kind of water-soluble chitosan adhesive bandage of following technical scheme; it is made up of gluing cloth (1), adsorptive pads (2), protecting film (3); it is characterized in that: adsorptive pads (2) is arranged in the middle of the gluing cloth (1), and protecting film (3) is arranged on gluing cloth (1), the adsorptive pads (2).

The area of described adsorptive pads (2) is 1/3rd of gluing cloth (1).

Described adsorptive pads (2) is to be made by the water-soluble chitosan fiber cloth

The centre of described protecting film (3) disconnects.

This novel adhesive bandage is at the defective of common adhesive bandage, design is transformed from adsorptive pads, do not re-use common cotton fiber cloth or chemical fiber cloth adsorptive pads, but employing is that the adsorptive pads that a kind of novel water-soluble chitosan biological fiber cloth is made replaces common cotton fiber cloth or chemical fiber cloth adsorptive pads; Chitosan is from halobiontic fish, shrimp, the material that extracts in the housing of Eriocheir sinensis, make water-soluble fibre cloth by a series of technical matters, with perusal, chitosan water-soluble fibre cloth and general fibre cloth differences in appearance are little, but in immersing water or behind the colourless solution, become transparent spawn with regard to moment, in becoming the process of gel, not only can absorb more than the moisture content of own vol more than 20 times, keep moisture state, can also impel wound healing, medical circle is generally acknowledged under moistening environment, fast 1.5 times than the environment of drying of the healing rates of wound.

Chitosan material is the unique positively charged pure natural macromolecule polysaccharide of nature, be described as the protein that continues, the 6th biological element of needed by human after saccharide, fat, vitamin, the mineral, have excellent biological compatibility and degradability, can stop blooding, antibiotic, ease the pain, suppress the generation of cicatrix, effectively promote wound healing, particularly to burn, the reparation of scald is especially outstanding, and this utility model belongs to use first in this field.

The advantage of this utility model is: simple in structure, and practicality reasonable in design, safety and sanitation, the adhesive bandage of alternative common cotton fiber and chemical fibre adsorptive pads impels the faster and better healing of wound.And it is antibiotic to have brute force, the moment hemostasis, and powerful pain-stopping, quickly-healing absorbs fully, and the adhesion wound suppresses the effect that cicatrix generates.

The specific embodiment

A kind of water-soluble chitosan adhesive bandage, it is made up of gluing cloth (1), adsorptive pads (2), protecting film (3), it is characterized in that: adsorptive pads (2) is arranged in the middle of the gluing cloth (1), and protecting film (3) is arranged on gluing cloth (1), the adsorptive pads (2); The area of adsorptive pads (2) is 1/3rd of gluing cloth (1); Adsorptive pads (2) is to be made by the water-soluble chitosan fiber cloth; The centre of protecting film (3) disconnects.

During use protecting film is removed, adsorptive pads places on the wound of clearing up, and adhesive tape is bonded on the skin of wound circumference, and adsorptive pads is fixed.Adsorptive pads runs into blood, can become translucent gel, plays hemostasis, and is antibacterial, and analgesia is short, suppresses the effect that cicatrix generates.Change once about general a couple of days, perhaps behind wound healing, take off.

Claims (4)

1. water-soluble chitosan adhesive bandage; it is made up of gluing cloth (1), adsorptive pads (2), protecting film (3); it is characterized in that: adsorptive pads (2) is arranged in the middle of the gluing cloth (1), and protecting film (3) is arranged on gluing cloth (1), the adsorptive pads (2).

2. a kind of water-soluble chitosan adhesive bandage according to claim 1, it is characterized in that: the area of adsorptive pads (2) is 1/3rd of gluing cloth (1).
