Description
Technical field
The present invention relates to amenities technical fields, and in particular to the new Wound dressing that a kind of patient in hospital uses.
Background technology
Application also known as " hemostasis plaster " are most common a kind of surgical medicines in people's life, have hemostasis, protect wound
Effect is used suitable for minor cut or wound that wound more table is shallow, wound is neat totally, bleeding is few and need not suture, can had
Effect plays the purpose for preventing wound infection.Adhesive bandage is because its is easy to use, as the amenities of family's indispensability.Often at present
The adhesive bandage seen is that non-woven fabrics water absorption pad after sterilizing is clipped between mono layer gauze and medical adhesive tape or directly by non-woven fabrics to absorb water
Pad is fixed on medical adhesive tape surface, some drugs then can be also added on adhesive bandage with accelerating wound healing.However, existing skill
The adhesive bandage of art is mostly using single antibacterial structure, and the effect without high-efficiency antimicrobial.
The content of the invention
The technical problems to be solved by the invention are to overcome deficiency of the prior art, and it is an object of the present invention to provide a kind of hospital suffers from
The new Wound dressing that person uses.
The present invention is achieved through the following technical solutions：
The new Wound dressing that a kind of patient in hospital uses, it is described including carcass, adhesive layer, cotton layer and protective layer
Adhesive layer is located at the upper surface of carcass, and protective layer is located at the upper surface of cotton layer, is equipped between the adhesive layer and cotton layer
Bamboo fibre layer and moisture absorption layer, bamboo fibre layer are located at the upper surface of adhesive layer, and moisture absorption layer is located at the upper surface of bamboo fibre layer, and inhales
Wet layer is located at the lower surface of cotton layer, the gelatin and methyl-prop that the surface of the adhesive layer is esterified covered with 4- vinyl benzoic acids
Olefin(e) acid is esterified dextran, and the moisture absorption layer surface is covered with methacrylated amylopectin, polyethylene glycol dimethyl propylene
Olefin(e) acid ester, acrylamide.
Further, the upper surface of the moisture absorption layer is also coated with chitin layer.
Further, the thickness of the bamboo is 2.0-2.5mm.
Further, the methacrylated amylopectin is made of methacrylic anhydride and amylopectin.
Compared with prior art, the present invention it has the following advantages and advantages：
The new Wound dressing that a kind of patient in hospital of the present invention uses, the adhesive bandage can effectively be absorbed by moisture absorption layer
The blood of the wounded keeps dry and comfortable between adhesive bandage and wound, effectively prevents from combining between adhesive bandage and wound, and outer
Bamboo charcoal fiber can also effectively adsorb smelly scent molecule using its strong adsorptivity, eliminate wound peculiar smell, while adhesive layer covers nearby
Gelatin and methacrylated dextran covered with the esterification of 4- vinyl benzoic acids have been covered, has made it have higher adherency
Property, biomechanical property, moisture absorption layer surface is covered with methacrylated amylopectin, glycol dimethacrylates
Ester, acrylamide, help speed up wound healing.
Description of the drawings
Attached drawing described herein is used for providing further understanding the embodiment of the present invention, forms one of the application
Point, do not form the restriction to the embodiment of the present invention.In the accompanying drawings：
Fig. 1 is schematic structural view of the invention.
Mark and corresponding parts title in attached drawing：
1- carcass, 2- adhesive layers, 3- bamboos, 4- moisture absorption layers, 5- cotton layers, 6- protective layers.
Specific embodiment
Understand to make the object, technical solutions and advantages of the present invention clearer, with reference to embodiment and attached drawing, to this
Invention is described in further detail, and exemplary embodiment of the invention and its explanation are only used for explaining the present invention, do not make
For limitation of the invention.
Embodiment
As shown in Figure 1, the new Wound dressing that a kind of patient in hospital of the present invention uses, including carcass 1, adhesive layer 2, cotton
Yarn layer 5 and protective layer 6, the adhesive layer 2 are located at the upper surface of carcass 1, and protective layer 6 is located at the upper surface of cotton layer 5, described
Bamboo 3 and moisture absorption layer 4 are equipped between adhesive layer 2 and cotton layer 5, bamboo 3 is located at the upper surface of adhesive layer 2,
Moisture absorption layer 4 is located at the upper surface of bamboo 3, and moisture absorption layer 4 is located at the lower surface of cotton layer 5, the table of the adhesive layer 2
The gelatin and methacrylated dextran, the surface of the moisture absorption layer 4 that face is esterified covered with 4- vinyl benzoic acids cover
It is stamped methacrylated amylopectin, polyethylene glycol dimethacrylate, acrylamide；The upper table of the moisture absorption layer 4
Face is also coated with chitin layer, and the thickness of the bamboo 3 is 2.0-2.5mm, and the methacrylated branch forms sediment
Powder is made of methacrylic anhydride and amylopectin.
Since gelatin and methacrylated grape that the surface of adhesive layer 2 is esterified covered with 4- vinyl benzoic acids gather
Sugar, the gelatin and methacrylated dextran of the esterification of 4- vinyl benzoic acids are formed by curing sealing agent by ultraviolet light,
Make it have higher adhesiveness, biomechanical property；And the methacrylated amylopectin of moisture absorption layer 4 is by methyl
Acrylic anhydride is formed with amylopectin, helps speed up the healing of wound, and the upper surface of moisture absorption layer 4 is also coated with chitin
Layer, plays an important role of antibacterial.
Above-described specific embodiment has carried out the purpose of the present invention, technical solution and advantageous effect further
It is described in detail, it should be understood that the foregoing is merely the specific embodiments of the present invention, is not intended to limit the present invention
Protection domain, within the spirit and principles of the invention, any modification, equivalent substitution, improvement and etc. done should all include
Within protection scope of the present invention.
