Abstract
The utility model relates to a composite type hydrogel dressing, aquogel dressing packet draws together hydrophobic layer, absorbed layer and compound protective layer. Hydrophobic layer (1) is for containing the notched silicon gel coat of definite shape. Absorbed layer (2) comprise the transparence aquogel. Are compound protective layer (3) by adhesion layer (3 1 )With isolation layer (3 2 )Constitute. Adopt the utility model discloses aquogel dressing can reduce the wound infection the risk, maintain the wound cleaning, clear the offering convenience nature of creating for the wound of preventing to break after the aquogel imbibition, make the whole performance of dressing obtain improving simultaneously.
Description
Technical field
This utility model is related to medical hydrogel dressings（Wound treatment）Technical field, specially one kind have composite construction
Aerogel dressing.
Background technology
After " wet method " therapy of wound care was suggested from the 1950's, gradually obtain the accreditation of people, but traditional
Used by wound care, the dressing made by material such as gauze, cotton piece and various animal skin does not have or does not have enough moisturizings
Function is it is impossible to meet the requirement of " wet method " therapy.Absorbing wound exudate that therefore can either be good, has excellent moisture retention again
Hydrogel be gradually applied among " wet method " therapy of wound care by people.
Although hydrogel material has property and the moisture retention of excellent absorbing wound exudate, due to hydrogel intensity
Poor, tensile property is bad, and on the one hand this may make aerogel dressing cannot fit tightly with wound when using, and leads to hinder
Actinal surface faces the risk of infection, on the other hand, when " imbibition " phenomenon can occur after absorbed wound fluid, reduces further
The mechanical property of hydrogel, may lead to the spontaneous fragmentation of hydrogel in dressing, so that dressing loses using function or even shadow
Ring a series of wound hygienic issues such as the cleaning of wound.
Content of the invention
In order to solve existing technological deficiency, this utility model provides a kind of composite water gel dressing, can effectively solve
Certainly conventional hydrogels low strength and affect the problem of dressing serviceability.
To achieve these goals, this utility model adopts the following technical scheme that：A kind of composite water gel dressing, including
Hydrophobic layer, absorbed layer and composite protection layer；The outside of absorbed layer is fixed with composite protection layer, is fixed with thin inside absorbed layer
Water layer.
Technical scheme further, described hydrophobic layer is made up of the Silica hydrogel coating containing definite shape otch.
Technical scheme further, described otch through-silicon gel coat.
Further technical scheme, described otch be shaped as one of " ", " ", " ∩ ", " " or " recessed " or several
Plant composition.
Technical scheme further, described otch density is in 60,000～80,000/m2Between.
Technical scheme further, described Silica hydrogel coating layer thickness should be in the range of 0.5～2mm.
Technical scheme further, described absorbed layer is made up of transparence hydrogel.
Technical scheme further, the water absorption rate of described hydrogel should be in the range of 300～800%.
Technical scheme further, described composite protection layer is composited with laminating layer by sealing coat, and wherein laminating layer is located at
Between absorbed layer and sealing coat
Further technical scheme, described sealing coat be in polyesters or polyolefin based materials one or more be prepared into thin
Film.
Technical scheme further, the thickness of described thin film should be in the range of 5 μm～50 μm.
Technical scheme further, the moisture Penetration ration of described thin film should be in 500～10,000g/m2In the range of/24h.
Technical scheme further, described laminating layer is that in pressure sensitive adhesive, temperature sensitive glue and light-sensitive emulsion, one or more are prepared into
Coating.
Technical scheme further, the thickness of described laminating layer should be in the range of 5 μm～50 μm.
Compared with traditional dressing, of the present utility model be beneficial in that hydrogel colloid surface exist one layer carry certain
The otch Silica hydrogel coating of shape is coated.First, the selected Silica hydrogel containing definite shape otch in this structure can make
Wound fluid penetrates into absorbed layer by absorbed.Secondly, hydrophobic Silica hydrogel can prevent dressing adhesion wound.Finally,
This coating can prevent absorbing wound exudate after water-setting micelle colloid spontaneous be broken to wound surface, this not only can keep hinder
Mouth cleanliness factor, can be that the debridement of wound offer convenience again.
