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: 7836884Abstract: A double-body therapeutics face and tracheostomy mask which functions as both a mask for the nose and mouth of a patient and a mask for the tracheostomy tube area of a patient is disclosed. The mask of the present invention serves as a means for delivering a gaseous medicament or a liquid, such as liquid medication, in the form of a fine spray or mist to the nose, mouth, and trachea of the patient simultaneously. The upper body (1) of the mask fits over the nose and mouth area of the patient and the lower body (5) of the mask fits a patient's tracheostomy tube area. The upper and lower mask bodies may be connected to one another and to a nebulizing apparatus (4) and adjustable-length delivery conduit (17). Therefore, the double-body therapeutics face and tracheostomy mask of the present invention may be adjusted to comfortably fit the face and trachea area of any sized patient.Type: GrantFiled: July 6, 2004Date of Patent: November 23, 2010Inventor: Vivian A. Wright

Publication number: 20100287636Abstract: The invention provides methods and compositions for the treatment of asthma and bronchial inflammation, e.g., as induced by an allergen or toxin. In one aspect, the invention provides inhibitors of “Inducible T Cell Kinase” (ITK) polypeptides and methods of making and using them, e.g., as agents and pharmaceutical compositions to treat asthma. In one aspect, the invention is directed to ITK protein expression and/or activity inhibitors. In one aspect, these ITK protein expression and/or activity inhibitors are used with targeting agents. In one aspect, the ITK protein inhibitors of the invention are used to treat asthma. In one aspect, the invention is directed to ITK protein inhibitors as chimeric proteins comprising fragments or altered or truncated forms of ITK protein, or equivalent. In other aspects ITK protein is joined or fused to another moiety (e.g., a targeting domain) or to an antibiotic.Type: ApplicationFiled: May 15, 2008Publication date: November 11, 2010Applicant: San Diego State University Foundation, dba San Diego State University Research FoundationInventors: Constantine Tsoukas, John Lambris

Publication number: 20100242961Abstract: A breathing assistance system includes a gas delivery system including a gas flow generation device configured to generate a gas flow; a humidifier system including a liquid water chamber and an outlet, and a microporous filter. The gas delivery system and the humidifier system at least partially define a gas flow path from the gas flow generation device to the outlet of the humidifier system. The microporous filter is located along the gas flow path such that the gas flow generated by the gas flow generation device flows through the microporous filter, subsequently becomes humidified in the liquid water chamber, and subsequently flows through the outlet of the humidifier system. The microporous filter is gas-permeable and liquid water-impermeable, such that the microporous filter prevents liquid water in the liquid water chamber from flowing into the gas flow generation device in any orientation of the gas delivery system and humidifier system.Type: ApplicationFiled: March 31, 2009Publication date: September 30, 2010Applicant: Nellcor Puritan Bennett LLCInventors: Laurent Mougel, Arnaud Mocellin, Philippe Perine, Hossein Nadjafizadeh
