Abstract
Abstract A device for providing a metered dose of medication for inhalation by the patient. The device includes a case (10) having a conduit passage (68) connected to a mouthpiece (16) and having an angled door (58) activated to open the conduit passage when the patient inhales through the mouthpiece. The angled door is connected to an electrical circuit which is closed when the patient inhales through the conduit. The closed electrical circuit releases a spring- tensioned medicinal cartridge (24) to force the cartridge release pin (46) into a conduit aperture to realease a dose of medicine into the conduit for inhalation by the patient.
