Abstract: A method and apparatus that provides a continuous source of medical grade air. A substantially tubular housing includes a first end, an aperture extending through the housing, and a second end, opposite the first end. A valve extends from the first end of the housing for dispensing medical grade air to a patient.

Abstract: A method and system for generating vapors of liquid solutions where a pneumatically modulated liquid delivery system maintains a defined flow rate for a liquid solution. The pneumatically modulated liquid delivery system includes a flow meter configured to measure a flow rate for the liquid solution flowing from a pressure vessel; a microcontroller configured to determine a pressure necessary to achieve the defined flow rate; and an electronic pressure control unit configured to adjust the pressure inside the pressure vessel. The system includes a nebulizer coupled to the pneumatically modulated liquid delivery system configured to receive the liquid solution from the pneumatically modulated liquid delivery system at the defined flow rate and configured to generate an aerosol of the liquid solution. A heat tube can vaporize the aerosol generated by the nebulizer.

Abstract: A method and apparatus provides a continuous source of medical grade air. A substantially tubular and rigid housing includes a first end, at least one aperture extending through the housing and positioned a predetermined distance from the first end; and a second end, opposite the first end. A valve extends from the first end of the housing for dispensing medical grade air to a patient. A medical grade air compressor provides medical grade air for output by the valve, the medical grade air compressor being positioned within the housing on a side of the at least one aperture opposite the valve. An air flow generator is positioned between the second end of the housing and the medical grade air compressor, the air flow generator draws air into the housing through the at least one aperture. The air passes over and around the medical grade air compressor to reduce a temperature of the medical grade air compressor and to the medical grade air compressor for generating medical grade air.

Abstract: An apparatus includes a valve having at least two input ports. A first of the at least two input ports connected to a first source of material and a second of the at least two input ports connected to a second source of material. The also valve includes an output port and a valve selector for selectively connecting one of the at least two input ports to the output port. An electric circuit selectively connects an output device to receive data from a first sensor associated with the first source of material that senses at least one characteristic associated with the first source of material when the valve selector is in a first position connecting the first of the two input ports to the output port, and a second sensor associated with a second source of material that senses at least one characteristic associated with the second source of material when the valve selector is in a second position connecting the second of the two input ports to the output port.
