Abstract
The utility model provides an alginate woundplast, including baseband layer, alginate non -woven fabrics layer and protective layer, baseband in situ side is the rubberised layer, alginate non -woven fabrics layer is pasted in the intermediate position on baseband layer, the protective layer is two barrier papers, and every barrier paper length is greater than the half the of baseband layer, and the width equals with the baseband layer, by extending to the centre at the both ends on baseband layer, alternately overlaps in alginate non -woven fabrics layer upper portion. The utility model discloses a when wound care is applied to to the woundplast, have the healing time short, do not keep the scar, do not stanch and avoid causing advantage such as secondary damage with higher speed.
Description
Technical field
This utility model belongs to field of medical products, is specifically related to a kind of alginate adhesive bandage.
Background technology
In daily life, people inevitably produce some little wounds, such as knife injury, scratch, scald etc., and therefore, adhesive bandage becomes the necessary article of life and travelling oneself nursing.
From 20 the beginning of the century Johson & Johnson the earliest since invention adhesive bandage, adhesive bandage experienced by numerous improvement, such as, through the research and development of different manufacfure of strip producer, invent the adhesive bandage being applicable to the different parts such as joint, finger tip place, and improve the properties of adhesive bandage by adding different pharmaceutical in adsorptive pads, as antibiotic property etc.
Although the kind of adhesive bandage gets more and more, the material of adsorptive pads never changes for main this point with common cotton gauze, fundamentally constrains the result of use of adhesive bandage.The effect of the aspects such as tradition adhesive bandage has protection wound surface, absorbs exudate and keeps wound dry; but there is imbibition ability difference, easy and wound adhesion; the shortcomings such as secondary injury can be caused to wound during removal; in accelerating wound healing, minimizing cicatrization and acceleration hemostasis etc., also do not have facilitation effect, that especially causes the scald caused because of oil droplet and friction has the wound of more transudate without any curative effect.
Summary of the invention
For solving the problems of the technologies described above, this utility model is in particular to a kind of alginate adhesive bandage, there is stronger liquid-absorbent, accelerate to stop blooding, alleviate patient pain, there is certain fungistatic effect and have wound healing the adhesive bandage of facilitation, especially the tools such as small size scald and friction wound are had a good therapeutic effect, to safeguarding that human health has great importance.
A kind of alginate adhesive bandage, comprise baseband layer, alginate nonwoven layer and protective layer, be rubberised layer inside described baseband layer, described alginate nonwoven layer sticks in the centre position of baseband layer; Described protective layer is two panels release paper, and every sheet release paper length is greater than the half of baseband layer, and width is equal with baseband layer, is extended to centre by the two ends of baseband layer, in alginate nonwoven layer top juxtaposition.
Further, described baseband layer is PUR elastical cloth or medical PU film.
Further, described baseband layer is long is 60-80mm, and wide is 15-30mm.
Further, the length of described alginate nonwoven layer is 20-30mm, and wide is 10-20mm.
Further, described protective layer is two frame Racine release paper.
Compared with prior art, advantage of the present utility model and good effect are: a kind of alginate adhesive bandage of the present utility model changes traditional adhesive bandage and uses cotton gauze as the drawback of adsorptive pads, using alginate non-woven fabrics as water accepting layer, alginate belongs to natural polymer, has the following advantages: safety non-toxic, high-hygroscopicity, hemostatic, gel barrier, promote wound healing, bacteria growing inhibiting and less local pain etc.
Accompanying drawing explanation
Fig. 1. the structural representation of alginate adhesive bandage of the present utility model.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the technical solution of the utility model is described in further detail.
The utility model discloses a kind of alginate adhesive bandage, comprise baseband layer 1, alginate nonwoven layer 2 and protective layer 3 three part, described baseband layer is PUR elastical cloth or medical PU film; inner side is rubberised layer; have and paste performance, described baseband layer is long is 60-80mm, and wide is 15-30mm.Described PUR elastical cloth has a lot of pore, can ensure that wound gas flows; Described medical PU film main component is polyurethane, has the performance of waterproof and breathable.
Described alginate nonwoven layer is prepared from through processing technique for nonwoven fabric and cutting by alginate fiber.The length of described alginate nonwoven layer is 20-30mm, and wide is 10-20mm, sticks in the centre position of baseband layer.Main component in described alginate is calcium alginate, alginic acid zinc, copper alginate, alginic acid silver etc.
Described protective film is two frame Racine release paper, and length is greater than the half of baseband layer, and width is equal with baseband layer, is extended to centre by the two ends of baseband layer, occurs that top-bottom cross is overlapping in alginate nonwoven layer.
Product of the present utility model adopts alginate non-woven fabrics as absorbent material, and described alginate non-woven fabrics has superpower hygroscopicity, can absorb the transudate of wound and pus and blood etc. in a large number, reduce the replacing number of times of adhesive bandage when being applied to wound care.Alginate non-woven fabrics has unique one-tenth colloidality, when alginate adsorptive pads contacts with pus and blood with wound fluid, calcium ion in alginate fiber, zinc ion etc. can exchange with the sodium ion in transudate, form the gel of one deck softness, be attached to wound surface, for wound provides a moistening environment, discharge calcium ion etc. simultaneously.Theoretical according to " wet method healing ", moistening condition is more conducive to wound healing, and therefore alginate adhesive bandage can add wound healing promoting, and meanwhile, the calcium ion discharged can accelerate hemostasis.The soft gel formed can available protecting teleneuron, avoids environmental stimuli, and reduce local pain, gel is not easy to wound adhesion, is easy to remove, can not causes secondary injury to wound.In addition, alginate non-woven fabrics also has moisture retention, gel barrier, hemostatic, the advantage such as biocidal property and low viscosity.Therefore, the wound of more transudate is had to have good curative effect for burn, scratch etc.
Embodiment 1
Adopt PUR elastical cloth as baseband layer, long 70mm, wide 18mm, should have excellent permeability, and inner side is rubberised layer.The length of described alginate nonwoven layer is 25mm, wide 12mm, alginate nonwoven layer is pasted the centre position of the rubberised layer one side at PUR elastical cloth baseband layer.Protective layer is two panels identical lattice Racine release paper, long 37mm, wide 18mm; paste by the two ends of baseband layer; and extend to centre, occur that in alginate nonwoven layer place top-bottom cross is overlapping, the alginate adhesive bandage using PUR elastical cloth as baseband layer that obtained a slice is complete.
During use, from middle infall, protective layer is thrown off, alginate nonwoven layer is aimed at wound, then baseband layer is sticked on the complete skin of wound circumference and be fixed.
This adhesive bandage is affixed on 2 days, wound, find after removing, alginate nonwoven layer forms gel, and is adsorbed with more wound fluid, and wound heals substantially, and do not stick together when adhesive bandage is removed phenomenon, not for cause secondary injury to wound.
