Description
Technical field
The utility model belongs to medical material technical field, and in particular to a kind of promoting healing Wound protection pad.
Background technology
In daily life, some inevitable wounds that people occur generally carry out necessary disinfection and phase to wound
The nursing wrapping answered, process is complex, and needs to assist to complete.
Usually, after wound care, directly wrapped up using common gauze, this mode, permeability is strong, and wound holds
It is easily dry, and when removal gauze, it is difficult to it removes, secondary injury easily is caused to wound, meanwhile, pain is come than more sensitive crowd
It says, if there is foreign object encounters care layer, feeling of pain is also insufferable, if wound fluid is impregnated with care layer, is appeared
In outside, appearance is not only influenced, but also is easy to make clothing dirty.
Furthermore common gauze cannot active promotion wound healing, and the unscrupulous growth of scar can not be avoided, how more
The healing of fast, active promotion wound, is the problem of hospitalized patients are more paid close attention to.
Utility model content
To solve the above-mentioned problems, the utility model provides a kind of promoting healing Wound protection pad, have waterproof, it is ventilative, every
Bacterium, buffering, the effect of promoting healing play a part of to support wound, promote wound healing, reduce scar hyperplasia.The Wound protection pad
Using a kind of polyurethane foam with certain thickness and hardness, the wound after nursing is covered on so that foreign object is difficult to directly
Touch wound location, waterproof, every bacterium, it is ventilative while, play protection wound, intermediate flexible polyurethane foams layer contains
Promoting healing ingredient epidermal growth factor, alginate dressing layer be located at flexible polyurethane foams layer and hard polyurethane foams layer it
Between, in product in use, flexible polyurethane foams layer contacts wound, epidermal growth factor is discharged, the healing of wound, alginic acid are accelerated
Salt dressing layer also releasable calcium ion accelerates wound hemostasis, while between soft, hard bubble foam layer, can play the role of buffering.
To achieve the goals above, a kind of promoting healing Wound protection pad provided by the utility model, by rigid polyurethane foam
Foam layer, alginate dressing layer, flexible polyurethane foams layer and protective layer are constituted；The hard polyurethane foams layer is in groove
Shape；The alginate dressing layer and flexible polyurethane foams layer is set in the groove of hard polyurethane foams layer, described
Alginate dressing layer is set between flexible polyurethane foams layer and hard polyurethane foams layer；The protective layer is covered in soft
The upper surface of matter polyurethane foam, and extend to the edge of hard polyurethane foams layer upper surface.
Further, the upper table of the upper surface of the flexible polyurethane foams layer and hard polyurethane foams layer projection portion
Face is in same level.
Preferably, the height of the hard polyurethane foams layer is 5mm-10mm, a height of 3-8mm of groove, and shore hardness is
70-80 degree.
Preferably, the shore hardness of the flexible polyurethane foams layer is 20-30 degree, and the hole count of per inch is 100-130,
Liquid absorption amount is 10-15g/g.
Preferably, the hard polyurethane foams layer is made of hydrophobic polyurethane foam layer.
Preferably, the flexible polyurethane foams layer is by the hydrophilic polyurethane containing epidermal growth factor promoting healing ingredient
Froth bed is constituted.
Preferably, the content of the epidermal growth factor promoting healing ingredient of the flexible polyurethane foams layer is 10-15 μ g/
cm2。
Preferably, the calcium content of the alginate dressing layer is 5%-9%.
Preferably, the protective layer is the film adhesive tape coated with medical pressure sensitive adhesive.
Further, the shape of the Wound protection pad is round, ellipse or rectangular.
In use, selection is suitble to the Wound protection pad of wound size, protective layer is thrown off, by the soft poly- ammonia of Wound protection pad
Wound is completely covered in ester froth bed, and hard polyurethane foams layer is covered on intact skin, smooths Wound protection pad, support protection
Then wound uses gauze bandage to fix Wound protection pad as two layers of dressing.
The beneficial effects of the utility model：
（1）The hard polyurethane foams layer of the utility model has certain thickness and hardness, is fixed on intact skin,
Main support, cushioning and protection are played to wound.
（2）The flexible polyurethane foams layer of the utility model is hydrophilic polyurethane foam layer, has microcellular structure, is promoted
The absorbent of froth bed, can absorb oozing of blood and the sepage of wound, and can constantly discharge epidermal growth factor promoting healing ingredient,
It rises and promotes wound healing, reduce the effect of the hyperplasia of scar.
（3）The utility model increases alginate dressing layer in soft, rigid foam interlayer, and release calcium ion stops blooding, meanwhile, it can
The effect of buffering is further functioned as, the pressure to wound is reduced.
（4）The hard polyurethane foams layer of the utility model not only has the characteristics that waterproof and breathable, but also can effectively prevent
Only extraneous harmful substance contacts wound, further protects wound.
（5）The utility model is not provided with adhered layer, reduces sensitization rate of the medical adhesive to skin, for a wider population
It is general.
