Patent number: 11344695Abstract: A gas flow arrestor is provided that is configured to be coupled at one end to an oxygen concentrator, a VIPR type device associated with a compressed gas cylinder, or other gas delivery component such as a regulator or flowmeter and at the opposing end to a length of flexible tubing or hose that delivers the medical gas to the patient or patient breathing apparatus, such as a nasal cannula or breathing mask. The gas flow arrestor device includes a firebreak together with a visual flow indicator that is actuated by the flow of gas through the gas flow arrestor device. The visual flow indicator allows a user or patient to visually confirm from a distance whether or not gas is flowing to the patient or breathing apparatus.Type: GrantFiled: March 11, 2019Date of Patent: May 31, 2022Assignee: PRAXAIR TECHNOLOGY, INC.Inventors: Stephan Christophe Fernand Gamard, Christopher Hugh Davies

Patent number: 7785329Abstract: An adjustable reamer spindle is provided to aid a surgeon in controlling an instrument. The reamer spindle is easily disassembled for cleaning. The spindle has a repositionable handle, a locking ring, and an elastic device. The locking ring aids in holding the reamer spindle together. Removal of the locking ring against an elastic bias of a spring unfastens an end of the assembly in order to facilitate disassembly and/or cleaning. Adjustment of the position of the handle about the spindle enables the palm/grip of each hand to be changed in order to provide maximum control in different orientations.Type: GrantFiled: April 28, 2003Date of Patent: August 31, 2010Assignee: Greatbatch Medical S.A.Inventors: André Lechot, Hugh Davies, Michel Patrick White

Patent number: 7780669Abstract: An adjustable reamer spindle is provided to aid the surgeon in controlling the instrument. The reamer spindle is easily disassembled for cleaning. The spindle has a repositionable handle, a locking ring, and an elastic device. The elastic device biases against a handle locking mechanism that locks the repositionable handle at angular positions about an axis of the spindle. The elastic device further biases a locking ring into a locked position. The locking ring aids in holding the reamer spindle together. Removal of the locking ring against an elastic bias of the elastic means unfastens an end of the assembly in order to facilitate disassembly and/or cleaning. Adjustment of the position of the handle about the spindle enables the palm/grip of each hand to be changed in order to provide maximum control in different orientations.Type: GrantFiled: November 5, 2007Date of Patent: August 24, 2010Assignee: Greatbatch Medical S.A.Inventors: André Lechot, Yves Desarzens, Hugh Davies, Patrick White

Patent number: 7572259Abstract: An acetabular reamer for surgical use includes (a) a substantially hemispherical dome defining an equatorial plane, and (b) a reamer spindle interface structure fixedly attached to the inside of the dome so as to substantially inset the interface structure within the dome. This insetting of the interface structure helps minimize the size of an assembly of the reamer and a reamer spindle when performing minimally invasive joint surgery.Type: GrantFiled: September 12, 2003Date of Patent: August 11, 2009Assignee: Greatbatch Ltd.Inventors: Yves Desarzens, Hugh Davies, Patrick White, Andre Lechot

Patent number: 7473254Abstract: A rotary surgical reamer assembly for removing bone and tissue from a joint to facilitate the installation of a prosthetic device. The assembly includes a hollow reamer body having an opening and a base portion. The base portion includes a first pivoting link member, a wall with a surface defining a central cavity, and a plurality of spaced apart cutting sites defining apertures through said wall. A shaft is configured to be de-mountably attached to a rotary source of power. The shaft has a rotary axis and a second pivoting link member coupled to the first pivoting link member. The axis of the shaft forms an angle to the base portion. A mechanism adjusts the angle of the hollow reamer body from an un-deployed position to a deployed position.Type: GrantFiled: May 8, 2003Date of Patent: January 6, 2009Assignee: Precimed S.A.Inventors: Patrick Michel White, André Lechot, Yves Desarzens, Hugh Davies

Patent number: 6056634Abstract: Apparatus for applying a thin liquid coat to muscle meat comprises a conduit of generally constant cross-section along which the muscle meat is forced under pressure. The conduit has an entry port for the introduction of the liquid, and fixed structure is provided for promoting the relative movement of the meat chunks within the conduit to cause the liquid material to be smeared over the surface of the meat chunks. Suitably the fixed structure comprises at least one zone wherein the cross-section differs from that of the conduit. The cross-section of the zone may be characterized by one or more of an increased cross-section area, or by a decreased cross-sectional area, or by a different aspect ratio. The liquid may be one part of a two part settable adhesive; the other part of which is applied to the meat separately from the one part.Type: GrantFiled: June 5, 1996Date of Patent: May 2, 2000Assignee: Handtmann Piereder Machinery Ltd.Inventors: Gunther Schwarz, Morris Herbert Friske, Peter Hugh Davies
