Asthma inhalers are comprised of a medicine canister fitting inside a plastic sleeve. When the patient pushes the canister, the stem, a small metal pin, releases an actuator inside the sleeve allowing the medication to be released and inhaled by the patient. The stem must mate properly with the actuator to ensure the medication is ...
