Description
Technical field
This utility model relates to field of medical article technology, specifically comprises the non-woven fabric compounded dressing of a kind of alginate.
Background technology
The eighties in 20th century, alginate fibre started to be widely used in wound dressing aspect.After Sorbsan fiber commercial in 1981, alginate fibre is widely used in nursing aspect, the main dressing being used as absorption Wound exudate.At present, the alginic acid wound dressing more than 10 types has been had.Alginic acid fibre has high moisture absorption, easily removals, high oxygen flow, and the characteristic such as human compatibility is good, is applicable to very much doing medical surgical material.1962, British Winter found, the surface healing of wound is faster than drying regime in wet condition.Move to gushing of wound from the skin of health because the environment of humidity can accelerate epidermis cell, the speed that cicatrizes a wound is accelerated, and " wet therapy " expands the application of alginic acid fibre on medical dressing, gauze, binder.
But get over today of functionalization at medical dressing, the alginate fibre dressing that composition is single shows slightly not enough already in the treatment of some wound, in order to strengthen the suitability of alginate fibre, the means such as compound, grafting, modification can be passed through and give its other performance.Hydrogel, as the carrier of medicine, has quite outstanding sustained release performance, on this basis according to the medicine needing to add different efficacies for the treatment of to reach antibacterial, antiinflammatory, the object such as analgesia.But example alginate fibre and hydrogel being combined utilization was not still reported so far on document or patent.
Existing disclosed compound wound applies note, comprise tack coat, first dressing layer, the second dressing and sealing coat, the first dressing layer is fixed on tack coat, and between tack coat and sealing coat, the first described dressing layer is provided with hole, the second dressing is filled in hole, and described tack coat is provided with opening, and hole is corresponding with the position of opening.This type of deposited note utilizes the dressing changed in hole to reach timely absorbing wound exudate, but there is pore quantity limited, can only be provided with one or two, and there is the little problem of diffusion area, and skin glues the note shortcoming such as loosely.
Utility model content
The purpose of this utility model is to address the deficiencies of the prior art and deficiency, there is provided a kind of alginate non-woven fabric compounded dressing, multiple hole distribution can make the scope of the drug diffusion of pharmaceutical hydrogel layer in hole become large, simultaneously, making autohension better because filling pharmaceutical hydrogel layer, gluing note with skin and obtaining more firm.Also there is simple structure, reasonable, easy to use, there is high-hygroscopicity, keep wound moist, antibacterial, promote the advantages such as wound healing.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
The non-woven fabric compounded dressing of a kind of alginate, this combine dressing is made up of thin polyurethane rete, alginate nonwoven layer, pharmaceutical hydrogel layer and off-style paper layer; Described thin polyurethane rete is positioned at the bottom, with alginate nonwoven layer hot pressing compound; Described alginate nonwoven layer offers multiple hole, in described hole, fills pharmaceutical hydrogel layer; Described off-style paper layer covers on alginate nonwoven layer and pharmaceutical hydrogel layer.This combine dressing makes the scope of the drug diffusion of pharmaceutical hydrogel layer in hole become large by design multiple hole structure, meanwhile, making autohension better, gluing note obtain more firm with skin because filling pharmaceutical hydrogel layer.
Further, the aperture of described hole is 0.5cm ~ 1cm, and porosity is 50% ~ 70%.Distribution of pores expands drug diffusion area, keep wound moist, antibacterial, promote the effects such as wound healing.
Further, the thickness of described alginate non-woven fabrics is 0.5cm ~ 1cm.
Further, in described pharmaceutical hydrogel layer containing somatomedin, silver ion, salicylic one or more.
Further, the size of described thin polyurethane rete and the measure-alike of alginate nonwoven layer, the size of described off-style paper layer and the measure-alike of alginate nonwoven layer.
The beneficial effects of the utility model are: 1) this combine dressing is by design multiple hole structure, pharmaceutical hydrogel layer is filled again in hole, comparing the benefit directly coating hydrogel layer in alginate nonwoven layer is like this to allow alginate fibre directly and Wound contact, gives full play to the absorbency of alginate fibre; 2) on the other hand, if water pharmaceutical hydrogel layer is directly coated on alginate fibre, its medicine likely transfers to alginate fibre inside instead of through wound under the powerful absorbefacient effect of alginate fibre, thus affect therapeutic effect, and design of the present utility model makes pharmaceutical hydrogel layer and alginate fibre layer independent separately, both structure combines, give full play to its therapeutic effect; 3) multiple hole structural design makes the scope of the drug diffusion of pharmaceutical hydrogel layer in hole become large, meanwhile, making autohension better, gluing note obtain more firm with skin because filling pharmaceutical hydrogel layer; 4) this combine dressing has simple structure, reasonable, easy to use, there is high-hygroscopicity, keep wound moist, antibacterial, promote the advantages such as wound healing.

Detailed description of the invention
Below in conjunction with drawings and Examples, the technical solution of the utility model is described further.
As shown in Figure 1, 2, the non-woven fabric compounded dressing of a kind of alginate, this combine dressing is made up of thin polyurethane rete 1, alginate nonwoven layer 2, pharmaceutical hydrogel layer 3 and off-style paper layer 4; Described thin polyurethane rete 1 is positioned at the bottom, with alginate nonwoven layer 2 hot pressing compound; Described alginate nonwoven layer 2 offers multiple hole 5, the aperture in described hole 5 is 0.5cm ~ 1cm, porosity is 50% ~ 70%, fills pharmaceutical hydrogel layer 3 in described hole 5, in described pharmaceutical hydrogel 3 containing somatomedin, silver ion, salicylic one or more; Described off-style paper layer 4 covers on alginate nonwoven layer 2 and pharmaceutical hydrogel layer 3, and the thickness of described alginate non-woven fabrics 2 is 0.5cm ~ 1cm.The size of described thin polyurethane rete 1 and the measure-alike of alginate nonwoven layer 2, the size of described off-style paper layer 4 and the measure-alike of alginate nonwoven layer 2.
This combine dressing makes the scope of the drug diffusion of pharmaceutical hydrogel layer in hole and diffusion area become large by design multiple hole structure, meanwhile, making autohension better, gluing note obtain more firm with skin because filling pharmaceutical hydrogel layer.Also there is simple structure, reasonable, easy to use, there is high-hygroscopicity, keep wound moist, antibacterial, promote the advantages such as wound healing.
During use, off-style paper layer is peeled off, adhesive bandage is faced with alginate nonwoven layer 2 and pharmaceutical hydrogel layer 3, ensure that wound contacts with pharmaceutical hydrogel layer 3 with alginate nonwoven layer 2, utilize the multiple hole structural design of this combine dressing, while making alginate nonwoven layer 2 play its absorbency, pharmaceutical hydrogel layer 3 play its performance of keeping humidity and antibacterial, promote the effect such as wound healing.
It should be noted, the accompanying drawing of this description and the above description to the drawings and the specific embodiments are only for this utility model example is clearly described, are not the restrictions to embodiment of the present utility model.All do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., within the protection domain that all should be included in this utility model claim.
