ABSTRACT:
A system delivers a number of safe doses from a pressurized and metered medication canister via a dispenser to a patient. The improvement includes a counter device for accurately determining the number of safe doses delivered from the medication canister. Also, a warning device alerts the patient either visually, audibly, mechanically or in a combination thereof about an impending and then a final exhaustion of the number of safe doses delivered from the medication canister. The improved system takes advantage of the patient-actuated movement of the medication canister in the dispenser body to activate either an electronic or a mechanical counter device. Alternatively, the improved system may be patient-activated independently from, but in conjunction with, the dispensing of medication from the canister.
