Description
Technical field
The invention belongs to medical instruments field, and in particular to a kind of medical dressing, more particularly to a kind of visual waterproof dressing.
Background technology
Medical dressing, it is the articles for use of bag wound, to cover the medical material of sore, wound or other infringements.With to the surface of a wound
The physiopathologic further investigation of agglutination, understanding of the people to wound is also more and more deep, so as to result in
Medical wounded surface dressing is updated and developed.Medical dressing has turned into one of standing medicine in daily life, be usually used in compared with
In emergent nursing when small wound occurs, wound is sterilized and protects for stopping blooding, while the germ contamination in isolation environment.It is common
Generally by peel ply, adhesive linkage, separation layer and protective layer, adhesive linkage is usually waterproofing membrane structure for dressing, and separation layer is usually
The gauze structure of medicine is soaked with, protective layer is usually the adhesive plaster of waterproof or the structure for being completely coated with bonding agent.In use, this biography
Uniting, often gas permeability is very poor for dressing, causes skin ponding at wound dressing, is unfavorable for the healing of wound, and can not check wound in time
The healing state in face.Meanwhile the separation layer with ointment directly and Wound contact, is easily bonded at one with wound in traditional dressing
Rise, easily tear the wound of healing again.
Patent CN204840393U discloses a kind of visual protective dressing, including adhesive linkage, separation layer, peel ply.It is logical
Cross and use waterproof, ventilative transparent pellicle as tack coat, and porous spongy insulation layer structure, realize to wound can
Improve dressing gas permeability depending on monitoring, and by double-layer structure.But the product does not solve separation layer directly and Wound contact,
Easily sticked together with wound due to hydrops, cause the tear repeatedly of wound, so as to bring Affliction grade to patient.With life
The raising of bioplasm amount, for the comfortable facility of medical dressing and requirement attractive in appearance also more and more higher, it is necessary to enter traveling one to its material
The improvement of step.
The content of the invention
For solve to be unable to existing for prior art waterproof, wound it is not visible, easily with wound adhesion and not attractive in appearance etc. enough
Defect, the present invention provide a kind of visual waterproof dressing, and it has, and waterproof and breathable, wound are visual, can prevent infection, avoid tearing repeatedly
The advantages of lacerated wound mouth.
The technical solution adopted in the present invention is：A kind of visual waterproof dressing, is divided into four-layer structure, is followed successively by from top to bottom
Backing, absorbed layer, wound-contacting layer and release layer.
The effect of the backing is protection dressing main body, and backing is to cover polyethylene (PE) or cover polyethylene terephthalate
The transparent polyurethane film (PU films) of ester (PET) layer, wherein the polyurethane film (PU films) is coated with the acrylate of low allergy
Adhesive.The thickness of the PU films is 0.01-0.025mm；It is preferred that the thickness of the PU films be 0.01,0.015,0.02 or
0.025mm, more preferably 0.025mm.As the presently preferred embodiments, the PE or pet layer, can in it is separated, be divided into left and right two
Part, wherein middle breaking part facilitates the tearing off into S waveforms.The thickness of the PE layers is 0.01-0.05mm, is preferably
0.01st, 0.02,0.03,0.04 or 0.05mm, more preferably 0.05mm.The thickness of the pet layer is 0.01-0.06mm, preferably
For 0.01,0.02,0.03,0.04,0.05 or 0.06mm.
The effect of the absorbed layer is to absorb sepage, and absorbed layer is the polyurethane foam or polyvinyl alcohol foam of hollow out, position
The centre position of the one side of adhesive is scribbled in backing, area is less than the backing；The preferably multiple circle hole shapes or more of the hollow out
Side shape engraved structure, described each hollow out can be formed objects, or different size, it is preferable that the engraved structure into
Geometry arranges.The thickness of the absorbed layer is 1-5mm, more preferably preferably 1,2,3,4 or 5mm, 3mm；The Circularhole diameter
For 0.6-1.5cm, more preferably preferably 0.6,0.8,1.0,1.2 or 1.5cm, 1cm.
The effect of the wound-contacting layer is to prevent adhesion, and wound-contacting layer is the silica gel material of hollow out, it is preferable that the wound
Contact layer has an equal amount of area with absorbed layer, has same hollow out form.The thickness of the wound-contacting layer is
0.06-0.12mm, preferably 0.06,0.08,0.1 or 0.12mm, more elects 0.1mm as.
The material of the release layer is Ge Laxin paper, and it is divided into left and right two parts, wound-contacting layer and backing is completely covered.
The Ge Laxin paper grammes per square metre is 50-80g, preferably 50,55,60,62,65,70,75,80g, more preferably 62g.In use, tear
Expose wound-contacting layer after release layer, after being affixed at wound, tear PE or pet layer, you can check the surface of a wound at any time.
The beneficial effects of the invention are as follows：(1) dressing backing of the invention is overcome using the transparent PU films for covering PE or pet layer
The problem of PU film softnesses are not easy to paste, tears the PE or pet layer, can check wound healing feelings at any time after stickup
Condition, and checked without tearing, avoid the tear to wound；
(2) PU films have the characteristics of waterproof, ventilative, fungi-proofing, the PU films that the backing uses, have preferable ductility and
Water resistance, effectively bacterium can be prevented to invade, while there is preferable gas permeability, and wound surface formed one it is moist more
Cyclization border, beneficial to wound healing；
(3) use absorbed layer and contact layer double-decker of the invention, and use engraved structure, that is, gas permeability is ensure that,
It is easy to absorbing wound exudate, avoids absorbed layer to be directly easily sticked together with Wound contact again, to wound when causes to change
Tear, and contact layer used uses silica gel material, the not sticky moist wounds of silica gel material, can gently adhere to wound circumference skin
Skin, prevent absorbed layer in sepage reflux, reduce dipping risk, effectively reduce more change dressings when damage and caused pain.
