The alerting inhaler has a smaller air flow tube, with a front air inlet closed by a cover with a hole for slow, deep inhalation. An air inlet leads to alert giving whistle or vibrator or rotating vanes and longer mouth piece. The long spray rod of the drug vial with drug(s) in solvent, propellant, enters to air tube and ends in a novel jet spray nozzle at back of mouth piece. A handle for support, helps easy pressing of drug vial on the body. The long mouth piece is kept in mouth, air is sucked, alert is heard, drug vial is pressed, the spray is released at back of throat for easy flow into wind pipes and lungs for good relief. The inhaler gives an alert to time the spray, with delivery of spray at the back of throat and not outside mouth as now, has no mouth wastage, and reliably delivers drugs to lungs for good effect even for children and elderly persons! |
