Nebulizer systems and methods

摘要

A nebulizer assembly configured for removable attachment to an ultrasonic actuator includes a base plate portion, a porous mesh member, and a cover member. The base plate portion includes an opening extending therethrough, and is substantially rigid such that ultrasonic vibrations from the ultrasonic actuator may be transmitted through the base plate portion to the porous mesh member to vibrate the porous mesh member. The porous mesh member is configured for passage therethrough of a nebulized fluid, and is disposed in the opening of the base plate portion proximate a fluid emission side of the nebulizer assembly. The cover member is disposed on a second side of the nebulizer assembly opposite the fluid emission side. The cover member covers the opening and defines a cavity between the cover member and the porous mesh member. The cavity is configured to retain a fluid to be nebulized.

1. A nebulizer assembly comprising:
a base plate portion having an opening extending therethrough, the base plate portion configured to transmit ultrasonic vibrations from an ultrasonic actuator through the base plate portion; a porous mesh member configured for passage therethrough of a nebulized fluid, the porous mesh member disposed in the opening of the base plate portion proximate a fluid emission side of the nebulizer assembly, the porous mesh member configured to receive the ultrasonic vibrations from the ultrasonic actuator via the base plate portion, wherein the ultrasonic vibrations received by the porous mesh member via the base plate portion cause the porous mesh member to vibrate and pass droplets through the vibrating porous mesh member; and a cover member disposed on a second side of the nebulizer assembly opposite the fluid emission side, the cover member covering the opening and defining a cavity within the base plate portion between the cover member and the porous mesh member, the cavity configured to retain a fluid to be nebulized, the cover member configured to receive the ultrasonic vibrations from the ultrasonic actuator and to transmit the ultrasonic vibrations to the base plate portion.
