Patent number: 6467661Abstract: An adjustable, shoulder-strap assisting device having an elongate support member with a non-smooth surface on a shoulder engaging side. The elongate support member also has a deformable, rigid insert disposed therein such that the support member is capable of being custom fitted about the shoulder of the user in a non-slipping position. The shoulder-strap assisting device conforms to the contour of the user's shoulder and receives the shoulder strap of a backpack, golf bag, suitcase or the like and prevents the shoulder strap from moving relative to the device such that the load carried by the strap does not shift on the shoulder of the user.Type: GrantFiled: November 7, 2000Date of Patent: October 22, 2002Assignee: Kerl, Inc.Inventors: Louis A. Mistretta, Richard S. Binko, Floyd V. Edwards, Kenneth F. Munroe

Patent number: 5792122Abstract: A needle assembly is provided with a needle securely mounted to a needle hub. A shield assembly includes a plurality of telescoped tubes concentrically surrounding the needle. One of the telescoped tubes is securely connected to the needle hub. The other tubes in the assembly may be slid away from the needle hub. The tubes have combined lengths to enable complete shielding of the needle when the tubes are telescopingly extended. The distal-most tube, when the tubes are telescopingly extended, includes a tip guard which resiliently moves over the distal tip of the needle as the shield assembly is fully extended. The distal-most tube, when the tubes are telescopingly extended, of the shield assembly frictionally engages a catheter adapter to prevent withdrawal of the needle from the shield assembly until the tubes are fully telescopingly extended. As full shielding of the needle is reached, the shielded needle is separated from the catheter adapter.Type: GrantFiled: July 31, 1997Date of Patent: August 11, 1998Assignee: Becton Dickinson and CompanyInventors: Greg L. Brimhall, Charles W. Daugherty, Floyd V. Edwards

Patent number: 5346477Abstract: Apparatus for regulating pressure in and for controllably pressurizing infusion devices includes a flow-through pressure gauge for indicating and regulating the pressures within such infusion devices between minimum and maximum desirable pressures. Such apparatus includes a gauge, coupled between a fluid source and the bladder portion of the pressure infusion device. The gauge receives pressurized fluid from the fluid source, provides fluid to the bladder, indicates a range of fluid pressures in the bladder and maintains the pressure of fluid in the bladder between minimum and maximum pressures. The gauge includes a telescopingly coupled member to indicate a range of pressures in the bladder. A first valve permits the passage of fluid through the gauge and into the bladder when the fluid pressure exceeds a minimum pressure. A second valve prevents the passage of fluid through the gauge and into the bladder when the fluid pressure exceeds a maximum pressure.Type: GrantFiled: October 1, 1991Date of Patent: September 13, 1994Assignee: Harmac Medical Products, Inc.Inventors: Floyd V. Edwards, Norman M. Strobel

Patent number: 5053012Abstract: Pressure infusion apparatus for controllably pressurizing infusion bags includes a flow-through pressure gauge for indicating the pressures within such infusion bags between minimum and maximum desirable pressures. A lower housing member includes a chamber and an inlet to the chamber for receiving a flow of fluid from suitable sources of pressurized fluid. A resilient member seals the chamber and is used in cooperation with telescoping members in a downstream portion of the gauge for indicating a range of pressures within the chamber from predetermined minimum pressures, below which the gauge will not indicate, and predetermined maximum pressures, above which is dangerous for continuing use of the pressure infusion apparatus. The gauge is adaptable for both use in applications which are axial and transverse with respect to the flow of fluid therethrough.Type: GrantFiled: September 29, 1989Date of Patent: October 1, 1991Assignee: Harmac Medical Products, Inc.Inventors: Floyd V. Edwards, Norman M. Strobel
