ABSTRACT:
A conventional respiratory nebulizer has an emergency medication dose storage system delivering the stored medication dose directly to the nebulizing chamber with a single impulse of manual force to a simple mechanical delivery system, thereby making the nebulizer useable in two steps: (a) opening the medication capsule with a simple opening action; and (b) inhaling the nebulized medication. The nebulizer can be operated without disassembling the nebulizer housing so as to expose the nebulizing chamber and without manually opening the liquid medication container and, without spillage and without manual pouring of the liquid medication directly into the nebulizing chamber, and without reassembling the nebulizer housing before positioning the inhaler mouthpiece in the mouth so as to inhale the nebulized medication. The delivery system includes a pressure burstable seal at one end of the capsule, which is burst by the application of force against the opposite end of the capsule.
