Patent number: 7089940Abstract: A valve device, particularly for a breathing regulator for divers, including an inlet chamber which can be connected to a source of gas under super-atmospheric pressure, and an outlet chamber which is under a regulated pressure. A seating, which is movable under the influence of the super-atmospheric pressure and the regulated pressure, seals between the inlet chamber and the outlet chamber and has a through-passing passageway that interconnects the chambers. Also included is a valve body which is movably arranged in the seating such as to open and close the through-passing passageway in the seating. A servo element exerts on the valve body a force that depends on the position of the movable seating, so that varying force-influence on the valve body from the super-atmospheric pressure will be compensated for by a corresponding varying force from the servo element. This results in an essentially constant valve characteristic, while providing a mechanically simple solution at the same time.Type: GrantFiled: October 11, 2002Date of Patent: August 15, 2006Assignee: Poseidon Industri ABInventor: Anders Kellstr{hacek over (o)}m

Publication number: 20040000307Abstract: A device used with fluid canisters comprising a transparent body allowing the viewing of movement within the body having a minor and major cavity with a float indicator and float seat within the minor cavity. An inhaler top and bottom fits each end of the body forming an airtight chamber within the major and minor cavity above the float, the top having a seat to accept a canister and a nozzle aperture to accept a nozzle of the canister oriented to release fluid from the canister into the major cavity. An inlet through the minor cavity below the seat maintains pressure equal to pressure outside of the body within the minor cavity. Inhalation through a mouthpiece and one way valve reduces pressure within the major and minor cavity above the float drawing fluid through the one way valve creating a pressure difference across the float causing it to move.Type: ApplicationFiled: June 27, 2002Publication date: January 1, 2004Inventor: Khaja H. Khan

Publication number: 20030209238Abstract: A fluid can be discontinuously atomized with an atomizer of the present invention. The atomizer can include a helical spring, disk spring or gas spring, acting as a pressure spring, as an energy storage device, a cylinder, piston, two ducts and two valves. Atomization can be initiated manually by triggering a locking mechanism. The energy storage device can be disposed outside a storage container for the fluid. The energy storage device can be provided mechanical energy manually. Via the piston, the stored energy can exert pressure onto the fluid in the cylinder, which ranges from 1 MPa to 5 MPa (10 bar to 50 bar). Distribution of the droplet size in the atomized jet can be independent from the level of experience and behavior of the person actuating the atomizer, and can be adjusted in a reproducible manner. The mean droplet diameter can be smaller than about 50 micrometers. The mass flow of the fluid through the nozzle can be less than about 0.4 g/s.Type: ApplicationFiled: November 7, 2002Publication date: November 13, 2003Applicant: STEAG microParts GmbHInventors: Ralf-Peter Peters, Joachim Eicher, Holger Hollmann, Holger Reinecke, Stephen Terence Dunne

Patent number: 6644305Abstract: A nasal inhaler for introducing a substance to a nasal cavity of a user. The nasal inhaler comprises a chamber having an interior and an exterior, an outlet comprising an air exit passageway in flow communication with the interior of the chamber, a one-way air inlet valve in one-way flow communication with the interior of the chamber, and a dosage inlet passageway in flow communication with the interior of the chamber. A container includes a dispensing portion disposed in the dosage inlet passageway. In preferred embodiment, an adapter defines the dosage inlet passageway and is connected to the chamber. A mask also can be connected to the outlet. A method for dispensing a substance into the nasal cavity of the user comprises inserting the outlet into the nasal cavity, dispensing the substance into the chamber and inhaling through the outlet. A method for assembling a nasal inhaler assembly also is provided.Type: GrantFiled: April 11, 2001Date of Patent: November 11, 2003Assignee: Trudell Medical InternationalInventors: John MacRae, Martin Foley, Jerry Grychowski

Publication number: 20030178022Abstract: The present invention relates to pressurized metered dose inhaler (pMDI) actuators having with laser-drilled orifices of novel dimensions, and to medicinal aerosol solution formulation products comprising these actuators. In particular, the present invention relates to the optimisation of the output characteristics of drug solution formulations in hydrofluoroalkanes (HFAs) by use of pMDIs with actuators with laser-drilled orifices of specific dimensions. Moreover, the actuators of the present invention allow the use of solution formulations with a high ethanol content and a high ratio of ethanol to active ingredients and thus, the use of poorly soluble active ingredients in solution formulations and allow the use of solution formulations which are substantially free of low volatility components.Type: ApplicationFiled: December 19, 2002Publication date: September 25, 2003Applicant: Chiesi Farmaceutici S.p.A.Inventors: Rebecca Jayne Davies, David Ganderton, David Andrew Lewis, Brian John Meakin

Patent number: 6612306Abstract: A respiratory nitric oxide meter includes a respiratory connector designed to be supported in contact with a subject and to pass respiratory gases as the subject breathes. A flow pathway receives and passes the respiration gases. One end of the pathway is in fluid communication with the respiratory connector, and the other end is in fluid communication with a reservoir of respiratory gases. A nitric oxide concentration sensor generates electrical signals as a function of the instantaneous fraction of nitric oxide as the respiration gases pass through the flow pathway.Type: GrantFiled: October 11, 2000Date of Patent: September 2, 2003Assignee: Healthetech, Inc.Inventor: James R.

Patent number: 6595202Abstract: A drug delivery device and method is disclosed which produces aerosolized particles of pharmaceutically active drug for delivery to a patient by inhalation. The device is comprised of a liquid feeding source such as a channel to which formulation is added at one end and expelled through an exit opening. The feeding channel is surrounded by a pressurized chamber into which gas is fed and out of which gas is expelled from an opening. The opening from which the gas is expelled is positioned directly in front of the flow path of liquid expelled from the feeding channel. Various parameters are adjusted so that pressurized gas surrounds liquid flowing out of the feeding channel in a manner so as to maintain a stable capillary microjet of liquid until the liquid exits the pressure chamber opening and is aerosolized. The aerosolized particles having a uniform diameter in the range of about 1 to 5 microns are inhaled into a patient's lungs and thereafter reach the patient's circulatory system.Type: GrantFiled: September 30, 2002Date of Patent: July 22, 2003Assignee: Universidad de SevillaInventor: Alfonso Gañán-Calvo
