PCT No. PCT/GB91/01116 Sec. 371 Date Dec. 23, 1992 Sec. 102(e) Date Dec. 23, 1992 PCT Filed Jul. 8, 1991 PCT Pub. No. WO92/00770 PCT Pub. Date Jan. 23, 1992.An inhalation device for use with a pressurized aerosol canister. The device involves an electromechanical mechanism for applying a priming force to the aerosol canister prior to or at the start of inhalation. The device also involves a blocking mechanism. The electromechanical mechanism electromechanically applies to the aerosol canister a priming force sufficient to actuate the aerosol canister, and the blocking mechanism prevents the priming force from actuating the aerosol canister until inhalation is detected.
