Publication number: 20030149389Abstract: This invention is related to wound dressings, supports, protection and care in humans and animals. Commonly, adhesives and wraps are used for this purpose. However, the use of adhesive have multiple problems: they are difficult to use with elastic gloves since the adhesive tapes stick to the gloves, cause skin irritations and discomfort on removal, and do not adhere to the skin covered by hairs. Many times the hair must be shaved which is a process of its own. Wound inspections or the exchange of dressing multiplies their problems and prohibits this process. Furthermore, wound wrapping cannot be done by use of adhesive tapes in an effective and convenient manner. Then, of course, is the major issue of dressing a wound with one hand only, that occurs in certain circumstances. It is very important to have a system that allows a person to be able to dress a wound solely with one hand, since the other one may be wounded. These units are extremely helpful in this regard.Type: ApplicationFiled: January 31, 2003Publication date: August 7, 2003Inventor: Yousef Daneshvar

Patent number: 6495229Abstract: The invention relates to a adhesive article comprising at least one backing layer with a first and second surface and a pressure sensitive adhesive layer adhered first surface of the backing layer in a pattern, wherein the pattern of the adhesive layer has an adhesive free area of less than about 25% and wherein the adhesive article has a water vapor transmission rate of greater than about 2000 g/m2/24 hour. The invention also relates to a method of forming an adhesive article comprising (a) providing a release liner, (b) applying pressure sensitive adhesive in a pattern wherein the free adhesive area is less than 25%, and (c) applying a backing layer to the pressure sensitive adhesive. The present invention provides pattern coated adhesive bandages that strongly adhere to human skin while permitting water vapor transmission there through. Accordingly the present invention also provides methods of facilitating the healing of wounds using the pattern coated adhesive bandage.Type: GrantFiled: August 22, 2000Date of Patent: December 17, 2002Assignees: Avery Dennison Corporation, Johnson & Johnson Consumer Companies, Inc.Inventors: Theresa L.
