Description
Technical field
The utility model relates to medical instruments fields, particularly belong to a kind of novel alginate dressing that prevents adhesion.
Background technique
Alginate dressing is the alginic acid extracted in seaweed, is the insoluble polysaccharide of fibre types element.It made
Alginic acid is converted into a kind of calcium salt in journey.When contacting with wound exudate, the calcium salt of alginic acid can be exchanged by interionic, be made
Indissolubility alginate calcium becomes soluble mosanom, and releases calcium, has extremely strong absorbability.It ensure that wound is wet
Property healing environment, extend the dressing time, while making the necrotic tissue self-dissolving in wound.Calcium ion in alginate is in wound table
Face forms one layer of network gel and peomotes hemostasis.But existing alginate dressing is generally by alginate layer, medical adhesive tape
Composition.It needs to be fixed again with bandage after alginate dressing imbibition or wound penetrating fluid penetrates on medical adhesive tape；It leads simultaneously
It causes alginic acid salt deposit to be easy to stick together with the surface of a wound, causes surface of a wound secondary damage.
Utility model content
The purpose of this utility model is provided a kind of new to meet the purpose for absorbing wound exudate and adhesion wound
Type prevents adhesion alginate dressing.
To achieve the goals above, the novel alginate dressing that prevents adhesion of one kind provided by the utility model, by upper and lower two layers
Structure composition, and tight bond, superstructure are acid fiber by polylactic film layer, are made of acid fiber by polylactic, the acid fiber by polylactic
Film layer is made by electrostatic spinning technique, and the understructure is alginate nonwoven layer, is made of alginate fiber, described
Alginate nonwoven layer is made by wet spinning and needling process, and the acid fiber by polylactic film layer is evenly distributed with diameter and is
0.5 μm ~ 1 μm of micropore.
Preferably, the acid fiber by polylactic film layer with a thickness of 2 μm ~ 5 μm, the acid fiber by polylactic diameter is the μ of 200nm ~ 1
m。
Preferably, the alginate nonwoven layer with a thickness of 1mm ~ 3mm, grammes per square metre 110g/m2~150g/m2。
The utility model has the following beneficial effects: not only with stronger absorption sepage performance but also having prevents wound viscous
Even to prevent the surface of a wound from causing secondary damage.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the novel alginate dressing that prevents adhesion of the utility model；
Description of symbols: 1, acid fiber by polylactic film layer；2, alginate nonwoven layer.
Specific embodiment
The utility model is further described with reference to the accompanying drawing.Following embodiment is only used for clearly illustrating this
The technical solution of utility model, and cannot be used as a limitation the limitation protection scope of the utility model.
As shown in the figure: the novel alginate dressing that prevents adhesion of one kind of offer is made of, and closely glue upper and lower double-layer structure
Knot, superstructure are acid fiber by polylactic film layer 1, are made of acid fiber by polylactic, the acid fiber by polylactic film layer 1 is by electrostatic spinning skill
Art is made, and the understructure is alginate nonwoven layer 2, is made of alginate fiber, the alginate non-woven fabrics
Layer 2 is made by wet spinning and needling process；The acid fiber by polylactic film layer 1 with a thickness of 2 μm ~ 5 μm, the acid fiber by polylactic
Diameter is 200nm ~ 1 μm；The acid fiber by polylactic film layer 1 is evenly distributed with the micropore that diameter is 0.5 μm ~ 1 μm；The alginic acid
Salt nonwoven layer 2 with a thickness of 1mm ~ 3mm, grammes per square metre 110g/m2~150g/m2。
Finally, it should be noted that obviously, above-described embodiment is merely examples for clearly illustrating the present invention,
And it does not limit the embodiments.For those of ordinary skill in the art, may be used also on the basis of the above description
To make other variations or changes in different ways.There is no necessity and possibility to exhaust all the enbodiments.And thus
Changes and variations that derived from still in the protection scope of the utility model among.
