In the second position, the canister is removable from the cradle and the cradle extends at an angle from the patient breathing circuit. The interface mechanism advantageously provides visual indication when the canister is removed and the breathing circuit is operating as a closed loop system, without CO2 filtration. The mechanism also facilitates efficient and accurate fluid connection between the carbon dioxide absorption canister and the breathing circuit.Type: GrantFiled: April 13, 2005Date of Patent: September 16, 2008Assignee: The General Electric CompanyInventor: James N. Mashak

Publication number: 20080196725Abstract: A quick pressure reducer and cylinder valve for use with an SCBA includes a cylinder valve that connects to a pressure vessel, a pressure reduction assembly for reducing the pressure of breathing air provided by the pressure vessel, a probe, and an inlet/latch assembly. The probe includes a notch and a threadless probe tip, and the inlet/latch includes a corresponding receptacle and one or more latches adapted to fit into the notch to retain the probe in the receptacle. A pushbutton switch in the receptacle is triggered by insertion of the probe tip therein, thereby providing an electrical signal. Probes of different lengths may be used to correspond to different pressure capacities, and the inlet/latch assembly may be arranged either to permit the insertion of only probe size or may be arranged to accept both sizes but to function differently based on the size of the probe. The latches are inoperable except at or below a nominal pressure.Type: ApplicationFiled: April 29, 2008Publication date: August 21, 2008Inventor: Ronald B. Mele

Publication number: 20080178877Abstract: A hyperbaric oxygen therapy system includes a pressure vessel containing a gas, an oxygen concentration measurement apparatus for monitoring the concentration of oxygen in the gas, an environmental control apparatus for controlling the temperature of the gas in the vessel, and a pressure/ventilation control apparatus for controlling the pressure of the gas in the vessel. The pressure vessel is capable of accommodating a patient. The oxygen concentration measurement apparatus includes an oxygen concentration analyzer and a plurality of gas lines connecting the oxygen analyzer to the pressure vessel. The pressure/ventilation control apparatus includes a pressure controlling valve, a pressure sensor, a ventilation valve, and a controller having a programmable pressure profile. The environmental control apparatus includes a scrubber, a heat exchanger and a blower located within the pressure vessel. A compressor for the system includes a compressor silencer.Type: ApplicationFiled: April 3, 2008Publication date: July 31, 2008Applicant: HYPERBARIC OXYGEN THERAPY SYSTEM CONTROLSInventors: William T.

Patent number: 7353822Abstract: A medical device clamping assembly includes proximal and distal axially aligned members. The proximal and distal members are movable relative to each other. A channel is defined through the members for receipt of at least a portion of a treatment device therethrough. A clamping member is configured between the proximal and distal members and defines a portion of the channel. The clamping member is actuated between an unclamped configuration and a clamped configuration by moving one of the distal or proximal members relative to the other. In its clamped position, the clamping member clamps upon and restricts axial movement of the treatment device through the assembly; however, the assembling may move on or within the treatment device and does not necessarily limit at least partial retraction of the device from a patient but rather only restricts insertion of the device beyond that point at which the assembly contacts a stopper.Type: GrantFiled: April 27, 2004Date of Patent: April 8, 2008Assignee: Kimberly-Clark , Worldwide, Inc.Inventors: David Theron van Hooser, Edward B.

Patent number: 7320722Abstract: A personal respiratory protection device 10 that comprises a mask body 12 that has a structure 35 located on it for receiving a clean air supply source such as a filter cartridge 14. The clean air receiving structure 35 has a first threaded portion 34. The clean air supply source has a second threaded portion 58 that has a thread 60 that mates with a thread 36 of the first threaded portion 34. The first and second threaded portions 34 and 58 engage each other at a high thread pitch and include an integral détente. A stop prevents over-rotation of the clean air supply source 14 relative to the mask body 12 during the securement operation. The inventive device allows the clean air supply source 14 to be attached to the mask body 12 with minimal rotation and is sufficiently intuitive that users may only need one hand to attach and replace the clean air source component 14 without having to remove the respirator 10 from their face.Type: GrantFiled: October 29, 2004Date of Patent: January 22, 2008Assignee: 3M Innovative Properties CompanyInventors: William A.

Patent number: RE41298Abstract: The present invention relates to a device for delivering a supply of gases to a patient. The device includes a patient interface and connecting member. The connecting member is preferably a L-shaped swivelled connector that is capable of being fixed into one of two positions, a first position where the connector is freely rotatable within the patient interface, and a second position where an interference between the interface and connector prevents the free rotation of the connector within the patient interface. The present invention further relates to a connector that has outlet means, which includes at least one outlet vent and a funnel, which in use directs and passes a substantial portion gases expired from the patient through the outlet vent or vents.Type: GrantFiled: October 10, 2007Date of Patent: May 4, 2010Assignee: Fisher & Paykel Healthcare LimitedInventors: Nicholas Charles Alan Smith, Alastair Edwin McAuley, Chris Earl Nightingale, Ivan Milivojevic, Lewis George Gradon
