Patent number: 7481215Abstract: An anesthetic evaporator with a pressure control circuit has a differential pressure pick-up (18) can be calibrated in a simple manner. A switchover device (20) is provided according to the present invention at a bypass gap (3), which is designed to connect the gas inlet (4) directly with the gas outlet (5) via a first bypass line (23) and to bridge over the bypass gap (3) via a second bypass line (26) connected to a ventilation duct (27) in a first switching position. The gas flow from the gas inlet (4) to the gas outlet (5) is established via the bypass line (2) in a second switching position. The calibration of the differential pressure pick-up (18) with the pneumatic connections (16, 17) is performed in the first switching position of the switchover means (20) via the ventilation duct (27), which is open toward the ambient atmosphere.Type: GrantFiled: July 27, 2005Date of Patent: January 27, 2009Assignee: Dräger Medical AG & Co.

Publication number: 20080308100Abstract: A patient treatment system and method comprising a patient circuit, a pressurizing flow module disposed in the patient circuit, a humidifier disposed in the patient circuit, a monitor, sensors within the patient circuit, and a processor. The patient circuit delivers a flow of gas from a gas source to an airway of a patient. The pressurizing flow module elevates the pressure of the gas within the patient circuit. The humidifier elevates the humidity of the gas in the patient circuit to a circuit humidity level. The monitor monitors at least one parameter of the gas from the gas source. The sensors generate corresponding signals that can be processed to estimate a rate at which vapor is added to the gas in the patient circuit. The processor determines the humidity level of the gas in the patient circuit downstream from the humidifier based on the signals generated by the sensors and the at least one parameter of the gas in the gas source.Type: ApplicationFiled: July 5, 2006Publication date: December 18, 2008Applicant: RIC Investments, LLC.Inventors: J. Raymond Pujol, William Perroz, JR., Robert G. Rybicki

Patent number: 7458374Abstract: Disclosed is a method and device for rapid heating of a coated substance which preferably includes a drug to vaporized for inhalation therapy. A device in accordance with the present invention preferably includes a substrate which has an interior surface surrounding an interior region and an exterior surface upon which the coated substance is to be adhered. Though the substrate is preferably metallic, it does not need to be. A combustible element is placed in the interior region of the rigid substrate and an igniter is connected to the combustible element. The igniter is for initiating oxidation of the combustible element. Preferably, the coated substance is vaporized inside of a housing to allow the vaporized drug to aerosolize and be inhaled by a user.Type: GrantFiled: May 13, 2002Date of Patent: December 2, 2008Assignee: Alexza Pharmaceuticals, Inc.Inventors: Ron L.
