Description
Technical field
Medical treatment and nursing articles for use are the utility model is related to, are applied in particular to a kind of new chitosan composite wound.
Background technology
In medical care, Wound dressing product emerges in an endless stream, and has good protective effect to wound, is protected from
Extraneous pollution, second of injury is caused to wound, many convenience are also brought to people.
All the time, Wound dressing product is very different, but the deposited core of most products is still using conventional conventional absorbent paper
Cotton pad, and the material only plays a part of absorbing wound exudate for wound, can not active promotion wound healing, from basic
On constrain the effect of Wound dressing.
With the development of functional dressing, Wound dressing is constantly improving, and the productions such as alginate application occurs
Product, wound is healed under wet environment, promote the growth of wound granulation, but the effect of these products is still relatively more single
One.
It is additionally, since that the adhered layer permeability of most of Wound dressing is strong, and the diffusate of wound is readily volatilized so that wound
It can not be healed under wet environment, slow down the healing rate of wound to a certain extent.And water resistance deficiency, cause patient to exist
During shower and after the multiple-contact of water, the stickup of Wound dressing is set to fail, it is necessary to frequently change application.
Therefore, how to overcome disadvantage mentioned above, there is provided a kind of healing effect significantly, mitigate patient suffering, waterproof and breathable, conveniently
The Wound dressing of observation wound situation in time, is a necessary and meaningful thing.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, there is provided a kind of new chitosan is compound
Wound dressing, simple in construction, easy to use, waterproof and breathable, healing time is short, have the function that it is antibacterial, stop blooding, prevent adhesion, it is right
Wound has protective effect, and convenient observation wound healing situation.
To solve above-mentioned technical barrier, technical scheme provided by the utility model is：
A kind of new chitosan composite wound application, adhered layer, deposited sandwich layer and protective layer are followed successively by from top to bottom and is formed,
The adhered layer is made up of transparent material, the deposited sandwich layer for from top to bottom successively by compressed cellulose spongy layer and chitosan without
Layer of cloth to be spun to be combined, the chitosan nonwoven layer is completely covered compressed cellulose spongy layer and to extending around, until with
The adhered layer bonding, chitosan nonwoven layer is directly and Wound contact, covering compressed cellulose sponge are fixed on adhered layer.Shell
Glycan nonwoven layer can absorb oozing of blood and the sepage of wound, and gel is formed after imbibition, and gel can play the effect of preventing adhesion, together
When compressed cellulose sponge imbibition after expand rapidly, certain pressure is formed to chitosan nonwoven layer, then wound is formed
Certain pressure, blood vessel is blocked, further enhance the haemostatic effect of product.
Further, the chitosan nonwoven layer is prepared by carboxymethyl-modification chitosan, the chitosan without
The deacetylation for spinning layer of cloth is 85%-95%, thickness 2mm-4mm, grammes per square metre 120-180g/m2.Gathered by carboxymethyl-modification shell
The chitosan nonwoven layer that sugar is prepared possesses and has more preferable absorbent and gelling performance, while 85%-95%'s is deacetylated
Degree can effectively reduce the allergy probability of user.
Further, the surface of the compressed cellulose spongy layer carries micropore, thickness 1mm-2mm, the micropore
Aperture is 0.2mm-1mm.The gas permeability and absorbent of dressing layer can effectively be improved.In compressed cellulose spongy layer imbibition
Afterwards, its thickness will increase, and maximum can reach 7mm-10mm, certain pressure can be formed to wound, carry out physical stop
Blood.
Further, described transparent material is prepared by polyurethane film, and described polyurethane film upper surface applies
Pressure sensitive adhesive is covered with, polyurethane film has stronger water-proof breathable properties, and a kind of healing environment of moistening can be built to the surface of a wound, and
The situation of wound exudate oozing of blood can be directly observed, pressure sensitive adhesive plays fixed product.
Further, the adhered layer lower surface also includes one layer of PET film.In process of production, polyurethane film is answered
Close on a pet film, protection, fixed polyurethane film can be played a part of, PET film is relatively more stiffening, can improve adhered layer
Antiwear property.
Further, the PET film is divided into page two, extends from the easy-torn line of middle S shapes to both ends, until being completely covered viscous
Paste layer both ends, PET film is removed at easy-torn line using during product, leave the glue that polyurethane film is collectively forming with pressure sensitive adhesive
Band, this adhesive tape waterproof and breathable, transparent shape are convenient to observe blood oozing from the wound surface sepage situation.
Further, described pressure sensitive adhesive is in acrylate pressure sensitive adhesive, polyurethane contact adhesive, medical Medical PSA
Any one.
Further, the protective layer is page two, extends up to mutual covering from adhered layer both ends toward centre respectively, outside it
Edge is adhesively fixed with adhered layer outer rim.
Further, described protective layer is Ge Laxin silicone oil papers, has the advantages of easily peelable.
The beneficial effects of the utility model：（1）The effect of with wound wet union is promoted.The spy of chitosan dressing in itself
Property, there is function that is antibacterial, stopping blooding, and after progress carboxymethyl-modification, gelling performance enhancing is advantageous to prevent wound infection,
Wound adhesion is prevented, promotes wound healing.（2）Compressed cellulose sponge, expands rapidly after imbibition, wound can be formed necessarily
Pressure, further enhance the hemostasia effect of product.（3）Polyurethane film waterproof and breathable, transparent shape are convenient to observe wound feelings
Condition, the healing environment of moistening is provided to the surface of a wound.
