Abstract
This invention relates to methods of promoting the healing of skin wounds, products for promoting the healing of skin wounds and processes for making such products. More particularly, this invention relates to layered absorbent dressings which absorb wound exudate in conjunction with additional products for assisting the healing of wounds at each stage of wound healing, as well as methods of using these dressings and methods of making these dressings.
Claims22
A method of promoting the healing of skin comprising the following steps:
- (A) applying a primary absorptive skin-facing layer to the skin of a mammal having a wound said primary absorptive skin-facing layer absorbing wound exudate during the early inflammatory phase of wound healing and said primary absorptive skin-facing layer having the characteristics of absorbing fluid from the wound without adhering to the wound and which is sufficiently breathable to permit vapor to escape from the wound or skin site covered;
- (B) upon completion of the early inflammatory stage of wound healing, removing said primary absorptive skin-facing layer and applying a maintenance layer which regulates the temperature and humidity of the wound environment during the proliferative phase of wound healing;
- and
- (C) upon the completion of the proliferative phase of wound healing, removing said maintenance layer and applying a barrier material which minimizes trans-epidermal water loss and enhances intercellular lipid fluidity of the skin during the phase in which the barrier properties of the skin are reestablished.

A composite absorbent product comprising:
- (a) a skin-facing acquisition facing comprising a film which is capable of being perforated without substantial stretching, said skin-facing acquisition facing having a skin-facing side and an outward-facing side;
- (b) an absorbent core contiguously associated with said skin-facing acquisition facing at its outward-facing side, said absorbent core having a skin-facing side and an outward-facing side;
- and
- (c) a barrier film layer contiguously associated with said absorbent core at its the outward-facing side of said absorbent core, said barrier film layer being breathable;
- said composite absorbent product having a Peak-load (5g) according to a Modified Circular Bend Procedure of from about 150 to about 250 g and wherein said composite absorbent product contains void volumes which are available for containing fluid.
2 more elements
A process for making an absorbent composite laminate comprising the following steps:
- (a) providing an acquisition layer and a contiguous absorbent core layer having an acquisition layer-facing side and an outward-facing side which are capable of bonding to each other when heat is applied;
- (b) perforating and embossing said acquisition layer and said contiguous absorbent core layer at a temperature of from about 150 to about 225° F., thus fusing said absorbent core layer to said acquisition layer at the acquisition layer-facing side of said absorbent core layer;
- (c) applying an adhesive to the outward-facing side of said absorbent core layer and laminating a breathable barrier film to the absorbent core layer.
A skin dressing for the face comprising a composite absorbent product comprising:
- (a) a skin-facing acquisition facing comprising a film which is capable of being perforated without substantial stretching, said skin-facing acquisition facing having a skin-facing side and an outward-facing side;
- (b) an absorbent core contiguously associated with said skin-facing acquisition facing at its outward-facing side, said absorbent core having a skin-facing side and an outward-facing side;
- and
- (c) a barrier film layer contiguously associated with said absorbent core at its the outward-facing side of said absorbent core, said barrier film layer being breathable;
- said composite absorbent product having a Peak-load (5 g) according to a Modified Circular Bend Procedure of from about 150 to about 250 g;
- said dressing having the approximate shape of a face and containing apertures for eyes, nose and mouth;
- said dressing further containing score lines for pleats along its perpendicular axis, equidistant from the midline of the dressing and score lines for darts located such that each of said dart score lines is at a 45° angle from said midline, beginning at the peripheral edge of said dressing.
4 more elements
A method of making a skin dressing for the face comprising the following steps:
- (a) providing an absorptive layer;
- (b) cutting a facial-shaped mask in said absorptive layer;
- (c) cutting apertures for eyes, nose and mouth in said absorptive layer;
- (d) sealing the peripheral edges of said mask and said apertures using radiant energy or adhesive;
- (e) making at least two score lines on a vertical axis parallel with the midline of said mask, said score lines being equidistant from said midline;
- (f) making at least four score lines at 45° angles from said midline, at least one in each quadrant of said mask;
- and
- (g) folding said mask at said score lines to form at least one vertical pleat and at least four darts.
