Inhaler for treatment of lungs and respiratory passages - incorporates electromagnetically pulsed valve in mouth of exhalation vent above nebuliser of liq. medicament inhaled through mouthpiece

摘要

A nebuliser (1) operated by a lever (14) is connected by a pressure tube to a control unit (5) which times the opening and closure of a valve (4) by two coaxial electromagnets (8,9).
