摘要：
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. Aerosol generated by the aerosol generator 3 is delivered into a chamber defined by the nebulizer housing 2. Air passes into the chamber through air inlets 30. The air entrains the aerosolized medicament and the entrained aerosolized medicament is delivered from the nebulizer through the outlet 5.
