Further, the outside cladding of reinforcer has release paper to be provided with independent packaging structure.
Further, the thickness of the thin alginate medical film is one half of the thickness of the main alginate medical film.
Further, the water absorption device also comprises an outer water absorption ring; the outer water absorption ring is sleeved outside the main alginate medical film and bonded with the back lining layer, and the thickness of the outer water absorption ring is larger than the overlapping thickness of the main alginate medical film and the reinforcing core; the outer surface coating of outer water absorption ring has pressure sensitive adhesive, the material that outer water absorption ring adopted is multilayer non-woven fabric structure or ordinary absorbent pad material, when the dressing pastes and covers the surface of a wound, the back sheet pastes and covers on the skin, with the dressing tensioning, during the tensioning, outer water absorption ring receives the oppression, paste simultaneously and cover on the skin, simultaneously, receive oppression deformation, make alginate medical membrane and/or strengthen the core and laminate the surface of a wound, at this moment, light subsides cover between surface of a wound and the dressing, the dressing absorbs the sepage, slightly expand the back, because set up the inflation clearance between surface of a wound and the dressing, can not lead to the wound to be oppressed, in addition, back sheet and outer water absorption ring form twice to the surface of a wound outside and seal, guarantee that it is in anaerobic or hypoxic environment, reduce the chance that bacterium and surface of a wound contacted.
Compared with the prior art, the utility model discloses an alginate dressing for wound resumes on general dressing basis, through the enhancement core that increases independent encapsulation, resume the initial stage at the wound and use, increase of service cycle, form an outside bed course through setting up outer water absorption ring simultaneously, form the gel back to the dressing, provide certain structural support, protect the growth of granulation tissue.
