Embodiment 1

[0030] A bamboo chitosan functional dressing, comprising a water-locking layer on the outer surface, a skin layer on the inner surface and a dressing base layer in the middle, the raw materials of the dressing base layer include 1.5 parts by weight of chitosan fiber and 5 parts by weight of bamboo fiber And 3 parts by weight of viscose fibers, the total weight of the dressing base layer is 60g / m 2 The chitosan of the chitosan fiber adopted is a high-viscosity chitosan with a degree of deacetylation of 80%, and a viscosity of 0.8Pa·s. After the chitosan fiber, bamboo fiber and viscose fiber are laid, the dressing base layer of the non-woven fabric structure is formed by needle punching. The fiber raw materials are arranged alternately, and the bamboo fiber and viscose fiber are used as the skeleton, which can increase the firmness. Moreover, the effect of each functional component of the dressing can be made more durable. The skin-adhesive layer is an anti-seepage film layer m...

Embodiment 2

[0032] A bamboo chitosan functional dressing, comprising a dressing base layer on the outer surface and a skin layer on the inner surface, the raw materials of the dressing base layer include 1 weight part of chitosan fiber, 7 weight parts of bamboo fiber and 2 weight parts of viscose Glue fiber, the total weight of the dressing base layer is 100g / m 2 ; The chitosan of the chitosan fiber adopted is a high-viscosity chitosan with a degree of deacetylation of 90%, and a viscosity of 0.9Pa·s. After the chitosan fiber, bamboo fiber and viscose fiber are laid, the dressing base layer of the non-woven fabric structure is formed by needle punching. The fiber raw materials are arranged alternately, and the bamboo fiber and viscose fiber are used as the skeleton, which can increase the firmness. Moreover, the effect of each functional component of the dressing can be made more durable. The skin sticking layer is an anti-seepage film layer made of high molecular polymer, and the high m...

Embodiment 3

[0034] A bamboo chitosan functional dressing, comprising a water-locking layer on the outer surface, a skin-adhesive layer on the inner surface and a dressing base layer in the middle, the raw materials of the dressing base layer include 2 parts by weight of chitosan fiber and 3 parts by weight of bamboo fiber And 5 parts by weight of viscose fiber, the total weight of the dressing base layer is 180g / m 2 ; The chitosan of the chitosan fiber adopted is a high-viscosity chitosan with a degree of deacetylation of 95%, and a viscosity of 1.0 Pa·s. After the chitosan fiber, bamboo fiber and viscose fiber are laid, the dressing base layer of the non-woven fabric structure is formed by needle punching. The fiber raw materials are arranged alternately, and the bamboo fiber and viscose fiber are used as the skeleton, which can increase the firmness. Moreover, the effect of each functional component of the dressing can be made more durable. The skin-adhesive layer is an anti-seepage fi...

Abstract

The invention belongs to the technical field of a medical supply, and relates to a bamboo chitosan functional dressing containing bamboo fiber and chitosan. The bamboo chitosan functional dressing comprises a dressing matrix, wherein the dressing matrix is prepared from 1-2 parts by weight of chitosan fiber and 3-7 parts by weight of bamboo fiber; and the dressing matrix, which is of a non-woven fabric structure, is formed by needling the chitosan fiber and the bamboo fiber. The dressing disclosed by the invention can guarantee proper humidity and temperature on wound and stimulate healing of the wound; the dressing is excellent in antibacterial and bactericidal effects, firm and comfortable to use; the chitosan, as a natural high polymer material for forming hydrogel, becomes into gel in water, so that the chitosan is good in affinity and has certain elasticity and tension, which is beneficial for adhesion of the dressing to skin of a patient and for guaranteeing high comfort degree of the patient; the dressing is free from toxic and side effect, and is free from pollution to environment; the dressing has no medicine, which is beneficial for properties of the matrix, capable of accelerating healing of wound and guaranteeing durable efficacy, and is free from toxic and side effect; and the matrix is biodegradable and is pollution-free to environment.

Description

technical field [0001] The invention relates to a dressing, in particular to a bamboo chitosan functional dressing containing bamboo fiber and chitosan, and belongs to the technical field of medical supplies. Background technique [0002] Wounds after injury or surgery need to be treated with dressings to absorb excess exudate exudate from the wound and allow the wound to heal quickly. However, the existing dressings have some shortcomings: when there is too much exudate, the water-absorbing layer cannot completely absorb it, and it will seep again from the water-absorbing layer, causing the skin at the wound to be soaked and softened, the healing speed is slow, and even ulceration occurs , greatly increased the suffering of the wounded, for this reason, a large number of improved dressings have emerged one after another, as the Chinese patent No. CN203662986 disclosed a new type of foam composite wound dressing on June 25, 2014, which is set to absorb water. The fast water...
