Description

Wound hydrogel application based on hexagonal positioning and fixing structure

Technical Field

The invention relates to the technical field of hydrogel application, in particular to a wound hydrogel application based on a hexagonal positioning and fixing structure.

Background

Hydrogels are a class of very hydrophilic three-dimensional network-structured gels that swell rapidly in water and in this swollen state can hold a large volume of water without dissolving. Due to the presence of the crosslinked network, the hydrogel can swell and retain a large amount of water, the amount of water absorbed being closely related to the degree of crosslinking. The higher the degree of crosslinking, the lower the water absorption. Therefore, the hydrogel is mainly used for nursing wound, the hydrogel is mostly rectangular at present, the hydrogel is directly pasted at the wound when in use, a medical adhesive tape is adopted for fixing when necessary, the wound position is not a flat and smooth plane, particularly for joint positions, the rectangular hydrogel cannot be completely attached to the skin, meanwhile, the medical adhesive tape externally connected is adopted for adhesion fixing, the self-fixing effect is poor, the hydrogel and the skin cannot be tightly adhered, and the wound nursing effect is reduced; further, current aquogel adopts sealed wrapping bag to seal up for safekeeping more, during the use, tears sealed wrapping bag through spilling and draws the sack and tear again with inside aquogel and take out, on the one hand, sealed wrapping bag self is difficult to tear, is difficult to easily take out aquogel, and on the other hand, sealed wrapping bag can't utilize after tearing, causes certain medical waste.
