Patent number: 11324913Abstract: An anesthesia vaporizer system having a reservoir fillable with anesthetic agent from a bottle. A fill body defines a cavity that receives the anesthetic agent from the bottle via an inlet. The fill body further defines main and vent ports each communicating between the cavity of the fill body and the reservoir. A fill valve is receivable within the cavity of the fill body and moveable between open and closed positions. The anesthetic agent from the bottle flows through the inlet only when the fill valve is in the open position. A lower seal is receivable within the cavity of the fill body and moveable between open and closed positions by the fill valve. The vent port communicates between the cavity and the fill body only when the lower seal is in the open position. The lower seal is positionable in the open position when the fill valve is in the closed position.Type: GrantFiled: November 15, 2019Date of Patent: May 10, 2022Assignee: GE Precision Healthcare LLCInventors: Thomas L.

Patent number: 11253669Abstract: A method of drying an anesthesia breathing system includes removing a CO2 absorber from the anesthesia breathing system, when the CO2 absorber is connected to an absorber inlet port and an absorber outlet port. The method further includes moving a bag-to-vent flow diverter to an intermediate position so as to simultaneously open both a bag channel and a ventilator channel, and connecting an inspiratory port and an expiratory port of the anesthesia breathing system together. A dry gas source is connected to an absorber outlet channel, and then a dry gas flow is provided through the bag channel and the ventilator channel so as to dry out moisture from a bag circuit and a ventilator circuit of the anesthesia breathing system.Type: GrantFiled: May 7, 2019Date of Patent: February 22, 2022Assignee: GE Precision Healthcare LLCInventors: Timothy P.

Patent number: 8573248Abstract: A gas flow valve having pneumatic vibration dampening device to reduce the vibrations created by the flow of gas through the gas valve. The gas valve includes a gas flow conduit that terminates at a discharge opening. A valve member is movably positioned relative to the discharge opening and allows gas flow in a flow condition and prevents the flow of gas in a seated position. The valve member includes a gas passage formed within the valve member. At least one flexible membrane is mounted to the valve member and surrounds an outlet opening of the gas passage. The flexible membrane is inflated as the flow of gas within the gas flow conduit increases such that the flexible membrane contacts an inner surface of a stabilizing conduit. The interaction between the flexible membrane and the stabilizing conduit reduces the vibrations created by the flow of gas past the valve member.Type: GrantFiled: December 8, 2010Date of Patent: November 5, 2013Assignee: General Electric CompanyInventor: James N.

Patent number: 7591267Abstract: A breathing circuit for use with a ventilated patient that includes a heat exchanger for removing water vapor from the breathing gases to prevent condensation within the breathing circuit. The heat exchanger is positioned downstream from the CO2 absorber and receives the breathing gases from the CO2 absorber prior to delivery of the breathing gases to the inspiration limb of the patient circuit. The heat exchanger includes a plurality of inflow tubes and outflow tubes that are each open to a sump removably attached to the heat exchanger. The sump collects the water vapor condensed from the breathing gases within the heat exchanger.Type: GrantFiled: September 6, 2005Date of Patent: September 22, 2009Assignee: General Electric CompanyInventors: James N.

Patent number: 7487775Abstract: An arrangement and method is provided for controlling operational characteristics of medical equipment. A pressure sensor associated with the caregiver is arranged to sense changes in air pressure that correspond to breathing activity of the caregiver. The pressure sensor may comprise a neckband, headset, or the like. In the arrangement shown, a headset that is worn by the caregiver includes a disposable tube connected to a pressure transducer such that the pressure sensor senses changes in air pressure in the tube. An open end of the tube is positioned near the mouth of the caregiver to receive changes in airflow from the caregiver's mouth. The pressure sensor is in communication with a controller associated with the ventilator. The controller is arranged to control at least one operational parameter of the ventilator, such as the delivery of respiratory support to the patient pr actuation of an oxygen flush valve on the ventilator, based upon the changes in air pressure sensed by the pressure sensor.Type: GrantFiled: January 31, 2007Date of Patent: February 10, 2009Assignee: The General Electric CompanyInventor: James N.
