Description
Technical field
The utility model is related to medical treatment and nursing articles for use fields more particularly to a kind of functional form wound repair to paste.
Background technology
In daily production and social activities, the destruction that various factors causes tissue or organ can unavoidably occur,
I.e. usually said wound, wherein most commonly seen by the wound problem brought of colliding with, wound.Only it is difficult to by wound self-healing
Up to good recovery effects, and reparation speed is slow, deals with improperly, will appear wound and is not cured, superinfection, generates apparent scar
The problems such as, so corresponding dressing or trauma plaster assist wound is usually selected to nurse, accelerate the reparation and healing of wound.
Traditional medical reparation is pasted mainly using non-woven fabrics as carrier, by drug coat or dip dyeing in non-woven fabrics, utilizes cotton
Non-woven fabrics is fixed at traumatic wounds by cloth, adhesive tape, and then is repaired to wound, and uncontrollable factor is more, cell toxicant easily occurs
Property, wound tissue infection and cutaneous anaphylaxis.Although currently, having gradually appeared portable reparation patch in the market, it is also equipped with
Antiphlogistic antibacterial, the hemostasis targeted drugs such as antipruritic, but still will appear that efficacy time is short, permeable breathable is poor in use
The problems such as.Therefore, a kind of antibacterial anti-inflammatory, good permeability are developed, the wound repair patch that efficacy stability, duration are grown is that extremely have
It is necessary.
Utility model content
The purpose of this utility model, which is to provide one kind, having good antibacterial and anti-inflammatory effects, and permeable breathable is good, efficacy stability,
Promote the wound repair patch that wound heals comprehensively.
Technical solution used by the utility model is：
A kind of functional form wound repair patch, it is characterised in that：Including from top to bottom set gradually protective layer, functional layer,
And basal layer, the protective layer are strippingly covered in functional layer upper surface, the functional layer is by dressing layer, pressure-sensitive adhesive layer and thoroughly
Gas-bearing formation forms, and the pressure-sensitive adhesive layer is located at air-permeable layer upper surface, and the pressure-sensitive adhesive layer and air-permeable layer close-packed arrays are in dressing layer four
Week.
It is rectangle, length-width ratio 4 that the functional form wound repair, which sticks surface,：1.
The dressing layer is located in the middle part of functional layer, account for functional layer length 1/2, width 3/4.
The dressing layer is the chitosan containing epidermal growth factor/polyamide composite nano-fiber film, Xian Weizhijing <
100 nm。
It is 0.5~2mm that the protective layer, which uses thermoplastic polyurethane film or release film, thickness,.
It is 1.5~3.5mm that the air-permeable layer, which uses medical non-woven layer of cloth, thickness,.
The dressing layer thickness is the sum of pressure-sensitive adhesive layer and ventilative layer thickness, and thickness is 2~4mm.
It is 0.5~2mm that the basal layer, which uses the Non-woven tape of micro-porous permeable, thickness,.
The functional form wound repair patch thickness is 3~8mm.
The beneficial effects of the utility model are as follows：
(1) basal layer uses the Non-woven tape of micro-porous permeable, has good gas permeability, efficiently avoids because of wound
Phenomena such as wound that can not be caused by eupnea festers, empyema, epidermis rot.Meanwhile it being set respectively at dressing layer both ends
Air-permeable layer has been set, the characteristic of air-and water-permeable is further ensured.
(2) dressing layer uses the chitosan containing epidermal growth factor/polyamide composite nano fiber, the composite Nano fine
Dimension has the characteristics that several functions.First, chitosan/polyamide composite nano fiber has good biocompatibility, nontoxic
Side effect, the membrane structure that nanofiber is formed have a large amount of, uniform pore size distribution, permeable breathable good.On the other hand, shell is poly-
Sugar is a kind of positively charged natural alkaline polysaccharide with antibacterial anti-inflammatory, blood coagulation anastalsis, has good bio-compatible
Property, bioadhesive and promote drug absorption, be typical wound repair material.
(3) most importantly, dressing layer has the functional characteristic of swelling release drug, can directly substitute water-absorption fiber
The effect of cloth can not only absorb wound tissue's liquid, fester, additionally it is possible to achievees the purpose that stablize release epidermal growth factor, from
And making drug releasing rate uniformly reliable, the drug effect retention time is long, can effectively promote wound healing, prevents and inhibit scar
Trace generates.
