Description

Aseptic application of chitosan

Technical Field

The utility model relates to the field of medical equipment, especially a chitosan aseptic applying ointment or plaster.

Background

The traditional sterile application is medical absorbent gauze which is mainly used for hemostasis, and the water absorption pad of the existing sterile application product is a non-woven fabric absorption pad which only can play a role in absorbing wound exudate; the pure absorption of seepage cannot meet the market demand.

Chitosan (chitosan), also known as chitosan, is obtained by deacetylation of chitin (chitin) widely existing in nature, and is chemically named polyglucosamine (1-4) -2-amino-B-D glucose. Chitosan is readily soluble in weakly acidic solvents, and it is particularly noted that the dissolved solution contains amino groups (NH2+) that inhibit bacteria by binding negative electrons. The chitosan has the function of inhibiting the activity of bacteria, so that the chitosan has wide application in the fields of medicine, textile, food and the like.

Aforementioned aseptic applying ointment or plaster of chitosan, paper frame formula is from type paper constitution and has: and the release paper frame is positioned on the writing adhesive tape on the release paper frame.

The chitosan sterile patch comprises a chitosan water absorption pad which comprises the following components: the water absorption pad comprises a water absorption pad body, a chitosan fiber layer wrapping the water absorption pad body, and chitosan gel particles formed between the water absorption pad body and the chitosan fiber layer.

In the chitosan sterile patch, the water absorption pad body is water absorption non-woven fabric.

The chitosan sterile patch has the thickness of the water-absorbing non-woven fabric of 0.2-0.5 mm.

In the chitosan aseptic patch, the thickness of the chitosan fiber layer is 0.03-0.1 mm.

In the chitosan aseptic application, the thickness of the chitosan fiber layer is 0.05-0.07 mm.

The utility model discloses an useful part lies in:

the chitosan water absorption pad of the utility model not only can absorb water rapidly, but also has good bacteriostatic effect due to the matching of the chitosan fiber layer and the chitosan gel particles;

the structural design and the thickness selection of the water-absorbing non-woven fabric and the chitosan fiber layer ensure that the chitosan water-absorbing pad has good water-absorbing effect and good extension capacity;

the design of the release paper frame is convenient for writing marks.
