A pressure activated electronic switch connected to the power source is responsive to a selected amount of voluntary fingertip, pressure for opening the solenoid valve to transmit the gas therethrough to a conduit, which further transmits the gas to a destination for use or storage.Type: ApplicationFiled: April 5, 2013Publication date: August 29, 2013Inventor: Frank Levy

Patent number: 8511299Abstract: An apparatus for metering the delivery of an aerosol. The apparatus has a variable acoustic source and a microphone, both acoustically coupled to a volume having a fluid region and an air region. The apparatus may also include a processor to determine a volume of the air region based on signals received from the microphone and the variable acoustic source. A fluid valve is coupled to the processor, and is configured to allow an amount of fluid to exit the fluid region associated with the volume of the air region. An atomizer, coupled to the fluid region, is configured to aerosolize at least a portion of the fluid.Type: GrantFiled: October 4, 2010Date of Patent: August 20, 2013Assignee: DEKA Products Limited PartnershipInventors: David E. Altobelli, Russell Beavis, Larry B. Gray, Derek G. Kane

Patent number: 8511301Abstract: There is provided a liquid formulation ejection device which improves reliability of inhalation even in a case where a preejection is performed and resolves a concern about hygiene. The liquid formulation ejection device (1) ejects a liquid formulation in a form of liquid droplets into an inhalation flow path (20) and allows a user to inhale the formulation. The liquid formulation ejection device (1) includes an ejector (11) for performing normal liquid droplet ejection for inhalation and liquid droplet preejection not for inhalation, and a discharger (13, 14, 28) for removing liquid droplets ejected by the liquid droplet preejection out of an inside of the inhalation flow path (20).Type: GrantFiled: September 7, 2006Date of Patent: August 20, 2013Assignee: Canon Kabushiki KaishaInventors: Toshiyuki Nobutani, Mitsuru Imai

Publication number: 20130192595Abstract: Described is an apparatus for monitoring nitric oxide delivery, wherein such apparatus comprises a display that provides a visual and/or numeric indication of the calculated dose of nitric oxide. Also described is a method of monitoring nitric oxide delivery, wherein the breathing gas flow rate and therapeutic gas flow rate are measured and used to determine the calculated dose of nitric oxide, which is then displayed. In some embodiments, an alert is provided when the calculated dose rises above or falls below a predetermined level or range.Type: ApplicationFiled: March 13, 2013Publication date: August 1, 2013Applicant: INO Therapeutics LLCInventor: INO Therapeutics LLC

Publication number: 20130186392Abstract: An aerosol delivery system (e.g., MDI or nebulizer for delivering aerosolized medication to a patient) includes a temperature sensor (10) in an aerosol output pathway of the system. A controller (600) determines that an aerosol generator of the system has released aerosol when the sensor senses a predetermined temperature change in the pathway. The temperature sensor may also comprise a thermal flow sensor that includes a heater and upstream and downstream temperature sensors. The controller compares the upstream and downstream temperatures to determine the presence, direction, and/or magnitude of fluid flow in the pathway. The controller may use the aerosol detection and/or flow detection to monitor compliance with desired use of the system and/or provide real-time instructions to a user for proper use of the system. The controller may record the aerosolization and flow data for later analysis.Type: ApplicationFiled: December 16, 2010Publication date: July 25, 2013Applicant: KONINKLIJKE PHILIPS ELECTRONICS, N.V.Inventors: Jacob Roger Haartsen, Jonathan Stanley Harold Denyer, Michael James Robbert Leppard, Anthony Dyche, Ronald Dekker, Bout Marcelis

Patent number: 8486043Abstract: Described here are unit dose containers, methods, and kits for treating asthma and other pulmonary conditions by nebulization. The unit doses of active agents are provided in a low volume formulation, which results in faster nebulization of the unit doses. The containers are also formed to minimize internal surface area so that effective re-dispersion of the active agents can be achieved while reducing adsorption to the walls of the containers.Type: GrantFiled: October 13, 2008Date of Patent: July 16, 2013Assignee: MAP Pharmaceuticals, Inc.Inventors: Laxmi Iyer, Paul S.
