Abstract
The utility model relates to a piece of natural absorbable biological dressing for medical use, which is composed of a functional layer that is made of chitin fibrous hydroentangled non-woven fabrics in sequence, a buffering absorption layer that is made of other non-woven fabrics, and a dressing layer that is made of autohesion non-woven fabrics, wherein, all the three layers of material are made of non-woven fabrics and specially processed. Compared with common cotton gauze and hydroentangled non-woven gauze, the utility model has the obvious advantages multifunction, convenient use, etc.
Description
This utility model relates to a kind of medical dressing, the dressing of particularly a kind of natural medical absorbable biological.
Medical dressing is the medical supplies of using always as the protecting wound surface cladding material.In traditional medical procedure, for general skin wound, all to carry out bandaging method for treating, avoid wound to be infected, or it is injured again, thereby impel wound to heal as early as possible, yet conventional woven cotton cloth or water thorn nonwoven gauze are in use, need successively the stack of multilamellar gauze to be applied to be placed on the wound, use cumbersome, and body fluid adhesion easy and that wound oozes out, cause when removing cloth, staying new wound at the wound place of scabbing easily, bring unnecessary misery to the patient, particularly at the large-area burn of treatment, during scald, use conventional dressing meeting to cause certain difficulty to treatment, wound healing is slow.In recent years, along with the appearance successively and the clinical use of various anti-stick gauzes, reduced the not antiseized misery of bringing to the patient of normal gauze.Antiseized gauze has anti-adhesion effectiveness, but antiseized gauze biocompatibility is poor, and when promoting wound healing, effect is also not obvious, and have also can cause skin allergy.No matter be conventional gauze or anti-stick gauze, when making medical dressing, usually need dressing to be fixed on the wound surface in addition, use cumbersomely like this, also can cause skin allergy sometimes with rubberized tape.
Goal of the invention of the present utility model is to provide a kind of natural medical absorbable biological dressing that adopts the biomaterial chitin fiber as primary raw material.
The purpose of this utility model realizes in the following manner:
The dressing of a kind of natural medical absorbable biological is characterized in that the application layer that non-woven fabrics that described dressing is the functional layer that is made of natural polymer biomaterial hydro-entangled non-woven chitin fibre cloth successively, other non-woven fabrics constitutes buffering absorbed layer and one side scribble medical pressure-sensitive adhesive constitutes constitutes.
Described buffering absorbed layer is by constituting with one or more non-woven fabrics made as raw material in viscose rayon, cotton fiber, polypropylene or the polyster fibre.
Because natural polymer biomaterial chitin fiber has good biological activity and biocompatibility, can be absorbed by human body safety, therefore this utility model is compared with conventional dressing and is had the wound of protecting, inhibiting bacteria and diminishing inflammation, hemostasis, analgesia, promote the cell tissue growth, quicken wound healing, the buffering external force collision, characteristics such as self-adhesion is fixed, and breathable moisture permeability is good and easy to use.
Below in conjunction with accompanying drawing a step explanation is done in preferred embodiment of the present utility model.
Accompanying drawing is the cross section structure sketch map of a kind of natural medical absorbable biological dressing.
As shown in the figure, the dressing of a kind of natural medical absorbable biological successively by the spun-laced nonwoven fabric made from natural polymer biomaterial chitin fiber as functional layer 1, apply one deck medical pressure-sensitive adhesive non-woven fabrics as application layer 3 formations with one or more non-woven fabrics in viscose rayon, cotton fiber, polypropylene, the polyster fibre as buffering absorbed layer 2 and one side.
Claims (2)
1, a kind of natural medical absorbable biological dressing is characterized in that described dressing is that the functional layer (1) that is made of natural polymer biomaterial hydro-entangled non-woven chitin fibre cloth successively, the buffering absorbed layer (2) of other non-woven fabrics formation and the application layer (3) of the non-woven fabrics formation that one side scribbles medical pressure-sensitive adhesive constitute.
2,, it is characterized in that described buffering absorbed layer (2) is by constituting with one or more non-woven fabrics made as raw material in viscose rayon, cotton fiber, polypropylene or the polyster fibre according to right 1 described biological dressing.
