Patent number: 8322334Abstract: A nebulizer includes a receptacle for containing a liquid, a liquid-drawing tube, and a hollow cover including a partition plate dividing an interior of the cover into first and second chambers, first and second conduits each having an inlet end adapted to be connected to a compressed gas supply tube, and an outlet end communicated with the first chamber, and a mist output tube communicating fluidly with the second chamber. A nebulizing unit is connected to the outlet end of the first conduit and the liquid-drawing tube for directing a first compressed gas from the first conduit to the liquid exiting from the tube to convert the liquid into a mist. The second conduit introduces into the first chamber a second compressed gas which entrains the mist when flowing to the second chamber and exiting through the mist output tube.Type: GrantFiled: September 17, 2009Date of Patent: December 4, 2012Assignee: Galemed CorporationInventors: Gary C. J. Lee, Yu-Chien Yen, Thomas Loescher

Patent number: 8091545Abstract: Containers for incrementally dispensing pressurized contents are described. The containers comprise a vessel suited to contain pressurized contents, a port integral with the vessel and through which pressurized contents contained in the vessel can be released from the vessel, preferably incrementally in approximately equal amounts, and a measuring device disposed in or otherwise associated with the vessel such that the quantity or amount of contents in the vessel can be measured or assessed. The measuring device senses ambient conditions in the vessel and, directly or with other components, indicates, for example, the amount of pressurized contents remaining in the vessel and displaying it to an observer. Devices for incrementally dispensing pressurized contents from such containers are also described.Type: GrantFiled: December 22, 2005Date of Patent: January 10, 2012Inventors: Alan M. Schechter, Adam M. Schechter

Patent number: 7975687Abstract: The device and a process for the heating and humidification of gas, especially respiratory gas. Fluid from a fluid reservoir is supplied to a sprinkling type chamber where, for the purpose of humidification, it is moved through the gas. The point is that the fluid is heated by a temperature controlled heater to a preset temperature. In addition to the description of the device, a description of the process underlying the operation of the device is described.Type: GrantFiled: October 31, 2003Date of Patent: July 12, 2011Assignee: Grundler GmbHInventors: Christoph Gründler, Markus Gründler, Daniel Heine

Patent number: 7905228Abstract: A nebulizer for efficiently and reliably delivering aerosolized fluid to an inhaling patient is disclosed. The nebulizer includes a fixed diverter and a movable fluid orifice or fluid pathway connected with an actuator for responding to an inhalation or a manual actuation and beginning the nebulization process. Also provided is a method of providing nebulization including the steps of moving a fluid orifice or fluid pathway connected to an actuator so that the fluid orifice or fluid pathway reaches a nebulizing position during inhalation.Type: GrantFiled: October 3, 2006Date of Patent: March 15, 2011Assignee: Trudell Medical InternationalInventors: Rick Blacker, Evan Goodwin

Patent number: 7849852Abstract: A medical breathing assistance apparatus (20) for supplying pressurised gases to a patient is disclosed. The breathing assistance apparatus (20) comprises a heating chamber (29) and a pressure chamber (27) both adapted to contain water, and at least one pressure adjusting means (24,25,26). The pressure chamber (27) is connected to the heating chamber (29) and the pressure adjusting means (24,25,26) is located between the heating chamber (29) and a gases supplying means (23) supplying gas to both the pressure chamber (27) and heating chamber (29). The pressure adjusting means (24,25,26) is adapted to convert pressurised gases from the gases supply means (23) to two different pressures, one to each of the heating chamber (29) and the pressure chamber (27), so that water flows from said pressure chamber (27) to the heating chamber (29).Type: GrantFiled: February 3, 2004Date of Patent: December 14, 2010Assignee: Fisher & Paykel Healthcare LimitedInventors: Michael Brian Edward Bremner, Lewis George Gradon

Patent number: 7832394Abstract: Containers for incrementally dispensing pressurized contents are described. The containers comprise a vessel suited to contain pressurized contents, a port integral with the vessel and through which pressurized contents contained in the vessel can be released from the vessel, preferably incrementally in approximately equal amounts, and a measuring device disposed in the vessel. The measuring device senses ambient conditions in the vessel and, directly or with other components, indicates, for example, the amount of pressurized contents remaining in the vessel and displaying it to an observer; methods for comparing the amount of contents actually released from the vessel compared to a theoretical constant; and methods for time logging (alone or in conjunction with the logging of other data) the actuation of the dispensing valve for comparison to a prescribed method. Devices (including metered dose inhalers) for incrementally dispensing pressurized contents from such containers are also described.Type: GrantFiled: December 22, 2004Date of Patent: November 16, 2010Inventors: Alan M. Schechter, Adam M. Schechter
