Patent number: 6124522Abstract: A packaged article including an adhesive-sided article, such as an adhesive bandage, a release paper facing the adhesive side thereof, and packaging top support and bottom backing sheets. The facing surfaces of the top support and bottom backing sheets peripherally surrounding the adhesive-sided article have cohesive surfaces. An adhesive strip, preferably a double-sided adhesive strip, attaches the non-adhesive side of the adhesive-sided article to the top support sheet. Relative strength adhesives and cohesives are employed so that the bottom sheet and top sheet is first separated to leave the top sheet and adhesive-sided article together. The top sheet is used as an applicator for placing the article onto a target surface, such as a patient's skin. The cohesive surface of the top sheet surrounding the article does not adhere to the target surface. At the time, however, the top sheet "pops up" from the article now adhered in place. The top sheet is then removed by breaking the bond of the adhesive strip.Type: GrantFiled: December 8, 1998Date of Patent: September 26, 2000Inventor: Mark R. Schroeder

Patent number: 5833646Abstract: A hospital type of bandage integrates an absorbent pad and non-stick layer with a fluid-impermeable outer layer and an adhesive in a single composite structure. In a preferred embodiment the invention further includes means which may be used to turn the bandage inside out upon removal, so that surfaces once contacting a patient are no longer externally exposed. A bandage according to the invertible embodiment preferably includes a pocket formed on the side of the bandage facing away from the patient after application, this pocket being large enough to accommodate at least a portion of a human hand, and inside this pocket and located opposite the entrance is a means for grasping which may be pulled outwardly through pocket opening, thereby inverting the entire structure. Various forms of devices for grasping are possible as alternatives, including a string, a tab and a tab with one or more finger-receiving holes.Type: GrantFiled: July 1, 1997Date of Patent: November 10, 1998Inventor: Michael A.

Patent number: 5827213Abstract: A wound dressing is disclosed that is intended to be supplied to the user in generally planar condition and may then be easily shaped to conform with a joint surface, such as a heel or elbow, without forming wrinkles in that portion of the dressing overlying the wound and without causing potential leakage channels or gaps in the border portion of the dressing surrounding the wound. The dressing includes a layer of pliant adhesive material having particles of one or more water-absorbable and swellable hydrocolloids dispersed therein and a backing layer of a flexible (preferably elastomeric) material extending over one side of the adhesive layer. The dressing is contoured to provide a continuous border in which the adhesive layer has a thickness substantially less than in the central body portion of the dressing.Type: GrantFiled: October 19, 1995Date of Patent: October 27, 1998Assignee: Ole R.

Patent number: 5820578Abstract: A bandage has a central portion for application directly to a body wound and a plurality of adhesive tabs connected to and spaced around the central portion for adhesion to the body around and in spaced-apart relation to the wound. Each tab is capable of independent flexion. The bandage can be applied substantially without wrinkling to a wound administered to a convex, concave, or flexing body part, as well as to a wound administered to a body part that is flat and/or immobile. The bandage can be made to adhere reliably, despite any flexing or curvature of the body part.Type: GrantFiled: February 5, 1996Date of Patent: October 13, 1998Inventor: Christen Johansen

Patent number: 5810756Abstract: A perforated medical adhesive tape has a tape backing layer formed from flexible sheet material, e.g., plastic film, and a pressure-sensitive adhesive layer for bonding the adhesive tape to the skin of a patient. The pressure-sensitive adhesive layer is flexible, deformable, elastic and has a permanently tacky surface. The backing layer has a planar outer surface with a multiplicity of upwardly extending protrusions, i.e., minute mounds which are upward deflections in the tape with corresponding upwardly extending, downwardly opening concavities or indentations in its lower surface below each of the protrusions. Each of the protrusions has a pierced opening located at its approximate center. The openings are elevated above the planar surface of the tape, and each opening extends through both the tape backing and the pressure-sensitive adhesive layer to facilitate the diffusion of air and moisture vapor through the tape. The tape is pierced with a multiplicity of heated needles, each having a tapered point.Type: GrantFiled: November 22, 1996Date of Patent: September 22, 1998Assignee: LecTec CorporationInventors: David A. Montecalvo, Darrin J. Lee
