Abstract:
PCT No. PCT/GB93/02194 Sec. 371 Date Apr. 11, 1995 Sec. 102(e) Date Apr. 11, 1995 PCT Filed Oct. 25, 1993 PCT Pub. No. WO94/09912 PCT Pub. Date May 11, 1994A dispensing apparatus which defines an outlet through which a metered dose of liquid from a reservoir is dispersed as an atomized spray. A droplet of liquid is metered onto a perforate membrane which is vibrated by way of a piezoelectric transducer such that atomized droplets are dispensed through the holes formed in the membrane. At each actuation of a delivery device, which provides the metered quantity of liquid, the transducer is actuated so as to vibrate the membrane for a period greater than the dispensing period required for the droplet to be dispensed. The apparatus is particularly suitable for dispensing pharmaceutical preparations.
