Patent number: 5981822Abstract: The invention provides a wound dressing (1) comprising a wound contacting sheet (4) laminated to one side of an absorbent layer (3) of water-swellable absorbent material such as a polyurethane. A liquid water-impermeable backing layer (2) is laminated to the other side of the absorbent layer (3). The wound contacting sheet is provided with one or more slits (5) therein. Expansion of the absorbent layer (3) due to absorption of wound exudate causes the slits (5) in the wound contacting sheet (4) to expand, thereby allowing passage of high flow rates of wound exudate. If the flow of exudate falls, then the slits close, thereby avoiding excessive drying of the wound surface.Type: GrantFiled: April 28, 1998Date of Patent: November 9, 1999Assignee: Johnson & Johnson Medical, Inc.Inventor: Deborah Addison

Patent number: 5861348Abstract: The present invention provides a body-adhesive tape having adhesive properties preventing the tape from peeling off due to sweat when it is applied in an overlapped manner, and which also has good moisture permeability. In the body-adhesive tape, a base cloth is formed from a stretchable warp thread and a standard weft thread. On one side of the base cloth a plurality of pressure-sensitive adhesive layers are formed separated by appropriate gaps. The pressure-sensitive adhesive layers are formed so that they meander left and right along the length of the tape. At the gaps, the base cloth is exposed so there is permeability. Since the gap meanders, it is longer than the tape, and thus there is more exposure of the weave and more permeability. The pressure-sensitive adhesive layers meander so that the tape can be attached anywhere on the body and can respond to tension due to body movement from any direction.Type: GrantFiled: September 19, 1996Date of Patent: January 19, 1999Assignee: Kinesio Co., Ltd.Inventor: Kenzo Kase
