A hydrogel dressing for wound care and a method of making the same
By matching the proportions of the absorbent colloidal phase, the polyvinyl alcohol-based elastic phase, and the calcium carbonate-gluconide calcium ion-releasing component and controlling the molding sequence, the problem of balancing the processing fluidity and liquid absorption performance, structural integrity and wet water retention of hydrogel dressings was solved, and a sheet-like gel layer suitable for wound care was prepared.

AI Technical Summary
Existing hydrogel dressings suffer from difficulties in balancing processing fluidity and liquid absorption performance, as well as structural integrity and wet water retention.
By matching the proportions of the liquid-absorbing colloidal phase, the polyvinyl alcohol-based elastic phase, and the calcium carbonate-gluconolactone calcium ion-releasing component and controlling the molding sequence, an elastic-liquid-absorbing composite hydrogel layer is formed, which takes into account processing fluidity, liquid absorption, wet water retention, and structural integrity.
This invention achieves simultaneous improvement in processing fluidity, liquid absorption performance, and structural integrity within a sheet-like gel layer, while ensuring wet water retention, making it suitable for the preparation of dressings for wound care.
