Abstract
A wound dressing possessing a wound exudate-absorbing component and at least one liquid-impermeable dressing-securing component is manufactured from the same flexible, cellular, thermoplastic resin workpiece.
Claims10
A wound dressing for application to a wound site comprising:
- a) a wound exudate-absorbing component constructed from a flexible cellular structure fabricated from a flexible cellular thermoplastic resin workpiece, the wound exudate-absorbing component having a wound contacting surface;
- b) at least one wound dressing-securing component having a skin-contacting portion, the wound dressing-securing component integral with and adjacent the wound dressing-absorbing component and being fabricated from the same workpiece as the wound exudate-absorbing component, the wound dressing-securing component possessing a layer of adhesive on its skin-contacting surface;
- and
- c) a region of collapsed cellular structure where the wound exudate-absorbing component and the wound dressing-securing component meet, the region of collapsed cellular structure formed by compressing and heating the flexible cellular thermoplastic resin workpiece and being essentially non-absorbing for aqueous substances for substantially preventing the passage of wound exudate from the wound-absorbing component,
- the wound dressing being fabricated from a single workpiece.
