PERCUSSIVELY IGNITED OR ELECTRICALLY IGNITED SELF-CONTAINED HEATING UNIT AND DRUG-SUPPLY UNIT EMPLOYING SAME

摘要

Heating units, drug supply units and drug delivery articles capable of rapid heating are disclosed. Heating units (800) comprising a substrate (801) and a solid fuel (802) capable of undergoing an exothermic metal oxidation reactio n is disposed within the substrate (801) are disclosed. These heating units (800) can be actuated by electrical resistance or by percussion (803, 804). Drug supply units and drug delivery articles wherein a solid fuel is configured to heat a substrate to a temperature sufficient to rapidly thermally vaporize a drug disposed thereon are also disclosed.
