Abstract: A nebulizer (10) for providing a select oxygen concentration and total flow of respiratory gas includes at least two oxygen nozzles (102, 104, 106, 108), each oxygen nozzle having an outlet. A pressurized oxygen supply is connected in fluid communication to each nozzle. A liquid outlet (80) corresponding to each nozzle (102, 104, 106, 108) is positioned proximate the nozzle outlet of the corresponding nozzle for nebulization of liquid from the liquid outlet (80) in a stream of oxygen flowing from the gas outlet of each nozzle (102, 104, 106, 108). A liquid supply (174) is connected in liquid communication to each liquid outlet (80). An oxygen adjustment mechanism is provided in fluid communication with at least one of the oxygen nozzles (102, 104, 106, 108) for selectively recruiting the at least one oxygen nozzle and preventing gas from flowing from the at least one oxygen nozzle.

Abstract: A device for entraining a liquid into a carrier gas comprises a hollow cylindrical body having an inlet chamber separated from the interior of the body by a partition. A first nozzle and second nozzle are each supported in the partition and interconnect the inlet chamber and the body interior. A passageway connects a reservoir to the first nozzle so that a first stream of carrier gas flowing through the first nozzle aspirates a liquid within the reservoir and entrains the liquid therein. A second stream of carrier gas flows through the second nozzle and mixes with the first steam in the interior of the body, thereby forming a resultant carrier gas mixture that is lower in liquid concentration than obtainable by having the first nozzle alone. An air inlet opening with an adjustable cover communicates between the interior of the body and its exterior.

Abstract: A device and method for the aerosolization of a liquid, includes a liquid reservoir having a three dimensional geometric shape within a hollow cylindrical housing and a gas nozzle in the liquid reservoir. An internal component having a three dimensional geometric shape conforming to the internal walls of the liquid reservoir, having a liquid conduit and a liquid orifice, and minimally spaced from the internal walls of the liquid reservoir and the gas nozzle. The gas nozzle coupled to pressurized gas source, produces a high velocity gas stream which exits through the liquid orifice. A subatmospheric pressure is created within the minimal space between the liquid conduit, and gas nozzle. The liquid is aspirated from the minimal space between the internal component and the internal walls of the liquid reservoir, to the minimal space between the liquid conduit, and gas nozzle and out the liquid orifice.

Abstract: A T connection mouthpiece comprised of a first tubular member with open ends and internal, a tubular member with a smaller diameter having closed ends to define an air chamber. Proximate to the closed end of the air chamber and distal to the mouthpiece is an aperture. A second tubular conduit opens into the first tubular member to be attached to a nebulizer. On the external surface of the T connection mouthpiece and contiguous with the air chamber, is adhered a thin film of polyvinylidene flouride. When the patient inhales through the T connection, airflow is directed to the aperture to generate a fundamental tone, the acoustical energy is converted to electrical energy by the polyvinylidene flouride film. The electrical signal is received and processed by the electronic circuitry which energizes a solenoid valve normally closed to open and to allow for pressurized gas flow to activate the nebulizer. The aerosol is delivered synchronously during the inspiratory phase of the respiratory cycle.

Abstract: A position insensitive low resistance aspirator and nebulizer includes a generally disk-shaped hollow housing having an outwardly extending cylindrical input fitting and an outwardly extending oppositely positioned output fitting. A sleeve extends between the input and output fittings and communicates with the disk-like housing interior through a downwardly facing slot. A porous ring is received within the housing interior and defines a capillary between the outer surface thereof and the interior surface of the cavity. A gas pressure vaporizing assembly receives the liquid within the interior cavity through wicking and capillary action. In alternate embodiments, porous members having a dome shape and an annular cylindrical shape are also used.

Abstract: There is disclosed a device adapted to accurately deliver a selected concentration of a primary gas in a diluent gas, such as ambient air. The device of the invention includes a hollow diluter body having generally opposed ports for the ingress of a primary stream of gas and the egress of a dilution stream of gas. The interior of the body defines a dilution chamber and a vent chamber, both of which are open to the egress port. The top wall of the body is provided with a port for communication between the dilution chamber and the exterior of the body. A vent port in the housing provides communication between the vent chamber and the exterior of the device. Pressure sensitive sealing means normally closes the vent chamber to prevent communication between the chamber and the exterior of the device and is operative responsive to pressure in the vent chamber to open and allow communication between the vent chamber and the exterior of the device through the vent port.

Abstract: An apparatus is provided for delivering a fluid to an orifice of a patient. A delivery device, such as a mask or cannula with nostril tubes, has at least one electrode for contacting the patient's skin or other conductive surface. An alarm circuit produces an electrical alarm signal in response to an electrical condition. An electrical interconnection between each electrode and the alarm circuit is provided such that when the electrode is not in contact with the patient's skin or conductive surface the electrical condition is satisfied, thereby producing the electrical alarm signal.

Abstract: A device for aspirating liquids which is operable from any position or orientation includes a hollow housing which communicates with a source of carrier gas and a source of gas under pressure. A nozzle is disposed within the hollow housing through which the pressurized gas is directed to produce a high speed stream of gas. An entrainment member defining an aspiration chamber for the liquid is disposed in the housing with the aspiration chamber immediately adjacent to the nozzle outlet in the housing. A multi-directional liquid flow path communicating between the housing interior and the aspiration chamber is defined by the entrainment member and the edges thereof to provide fluid communication between the aspiration chamber and any point in the housing regardless of the orientation of the device.
