Patent number: 6187126Abstract: The present invention provides a tube and cable restraint comprising: a strip of flexible material having a generally elongated rectangular loop-section adapted to form a loop about the tube with an attachment means near the first end of the loop-section adapted to secure (e.g., adhere) the strip to a surgical drape and a refastenable loop forming means adapted to secure (e.g., adhere) the second end of the loop-section to the first end thereby forming a loop around the tube or cable. In another embodiment, the restraint is adapted to secure a tubular drape around a projecting object such as a microscope eyepiece.Type: GrantFiled: December 30, 1997Date of Patent: February 13, 2001Assignee: 3M Innovative Properties CompanyInventors: Robert J. Rothrum, Robert L. Wheeler, F. Andrew Ubel

Patent number: 5832925Abstract: An apparatus for sealing an environment defined by a periphery is provided. The sealing apparatus includes a first frame defining an opening and being disposed on the periphery of the environment and a second frame defining an opening. A flexible material is rotatably interconnected between the first frame opening and the second frame opening to form an iris aperture. The size of the iris aperture can be adjusted by rotating the second frame with respect to the first frame. The first frame may be secured with respect to the second frame in order to fix the size of the iris aperture. For securing the frames with respect to one another, hook and loop fastening material may be provided. The environment and periphery may, for example, be a surgical patient and a surgical drape, respectively.Type: GrantFiled: June 9, 1997Date of Patent: November 10, 1998Assignee: Minnesota Mining and Manufacturing CompanyInventor: Robert J.

Patent number: 5765566Abstract: The present invention provides a universal surgical drape kit, comprising: a plurality of drape panels each having a top surface and a bottom surface; and a plurality of tape attachment strips comprising a backing, an adhesive layer covering one side of said backing, and a liner. At least two of the tape attachment strips are adhesively attached to the top surface and along at least a portion of one edge of the drape panels and a second portion of the tape attachment strips overhangs the drape panels and is covered with a liner. The present invention also provides a surgical drape, comprising: a sheet of drape fabric having a rectangular fenestration cut therein; and four tape attachment strips comprising a backing, an adhesive layer covering one side of said backing, and a liner. The four tape attachment strips are adhesively attached to the top surface of the sheet along the edges of the fenestration and a second portion of the tape attachment strips overhangs the fenestration and is covered with a liner.Type: GrantFiled: July 11, 1994Date of Patent: June 16, 1998Assignee: Minnesota Mining and Manufacturing CompanyInventor: Robert J.

Patent number: 5673433Abstract: The present invention provides a garment (e.g., a surgical gown) having adhered thereto a conformable, thin polymeric barrier film. The barrier film provides fluid resistance to the garment while still allowing the garment to "breathe." In addition, preferred barrier films are resistant to the transmission of pathogens. The barrier film of the present invention, prior to being applied to a fabric substrate, is preferably provided as an assembly in the form of an individual sheet, a roll of material, or a pad of stacked sheets.Type: GrantFiled: December 13, 1994Date of Patent: October 7, 1997Assignee: Minnesota Mining & Manufacturing CompanyInventor: Robert J.

Patent number: 5618278Abstract: The present invention provides a fluid collection pouch which may be easily attached to a surgical drape or directly to a patient's skin. The fluid collection pouch comprises a front panel and a rear panel joined along common side edges (thus defining a fluid receiving chamber). The pouch has an open top end to which is adhesively attached a portion of a tape attachment strip. A second portion of the tape attachment strip overhangs the open top end of the pouch and is covered with a liner. In use, the liner is removed (thus exposing an additional portion of the adhesive surface of the tape attachment strip) and the exposed adhesive is placed against the surface to which the pouch is being attached. This design provides a leak free seal between the surface and the pouch, and fluid is able easily to flow over the sealed region into the pouch without being inhibited or directed away.Type: GrantFiled: July 11, 1994Date of Patent: April 8, 1997Assignee: Minnesota Mining and Manufacturing CompanyInventor: Robert J.

Patent number: 5616385Abstract: A multi-cycle refastenable tape closure system is disclosed. The tape closure system comprises a fastener tape component having double-coated surfaces of pressure sensitive adhesive having the same or substantially similar pressure sensitive adhesive properties and preferably also a release tape component having opposing surfaces of pressure sensitive adhesive and a low adhesion release layer. The fastener tape component and the release tape component are capable of firmly adhering to opposing body coverings or along opposing edges of one body covering and capable of releasably adhering to each other to provide a multi-cycle refastenable contact of opposing body coverings or closure of the body covering opposing seams in an overlapping, low profile manner. A method of using a multi-cycle refastenable tape closure system is also disclosed.Type: GrantFiled: October 6, 1994Date of Patent: April 1, 1997Assignee: Minnesota Mining and Manufacturing CompanyInventors: Robert J.
