Abstract: A supplemental oxygen delivery system is described in which Aerosol is delivered into a housing 10, 20, which sits in the circuit from the supplemental oxygen supply and optional humidifier. The supplemental oxygen passes through this chamber 10, 20 in which the aerosol is located, and collects the aerosol transporting it to a patient via a nasal cannula 3 or a face mask 4. An aerosol generator 9 is mounted to the housing 10, 20 and delivers aerosol into an oxygen stream 13 flowing between an inlet 14 and an outlet 15 of the housing 10. The housing 10 also has a removable plug 16 in the base 17 thereof for draining any liquid that accumulates in the housing 10. There is no disruption of oxygen delivery to patients using nasal cannulas who currently have to use a separate face-mask when receiving nebulized medication.

Abstract: A nebulizer 1 particularly for home use includes a housing 2 having an aerosol generator 3 mounted therein. The housing is closed by a hinged cap 4 and has an outlet 5 through which aerosol generated by the generator 3 is delivered. A suitable connector such as a mouthpiece 6 may be connected to the outlet 5. The housing 2 has a receiver for receiving a nebule 8. The receiver includes a slot 7 which is sized and/or shaped to accommodate only a nebule 8 of predetermined shape and/or size. The nebulizer cap 4 has a nebule opening device which may be in the form of a puncture pin 10 projecting therefrom to pierce the nebule 8 when the cap is moved to the closed position. The pin 10 is hollow or splined to regulate flow from the nebule. The nebulizer 1 also has a switch device for enabling operation of the aerosol generator 3 when the nebule 8 is opened. The switch device comprises a microswitch 12 on the housing which is engageable by a trigger 13 on the cap 4 when the cap is moved to the closed position.

Abstract: The invention provides a combination of a micro pump 27 or a micro valve with a vibrating mesh nebuliser 2. This is powered by a controller 3. The controller 3 may have modifications to provide the electrical drive mechanism for the pump 27 in addition to fulfilling the aerosol/nebuliser drive requirements. In one case the system is used for humidifying gas in a ventilator circuit. A humidifying agent (sterile water or sterile saline) is aerosolised and then delivered to a ventilator circuit 100 coupled to the respiratory system of a patient.

Abstract: A method for humidifying gas in a ventilator circuit 100, 101, 102, 105, 106 comprises aerosolising a humidifying agent such as water or saline using an aerosol generator 2 and delivering the aerosolised humidifying agent to the inspiration line 101 of the ventilator circuit coupled to the respiratory system of a patient. The aerosol generator 2 comprises a vibratable member 40 having a plurality of apertures extending between a first surface and a second surface. A controller 3 controls the operation of aerosol generator 2, for example in response to the flow of air in the inspiration line 101 as detected by a sensor 11.
