1. A portable, hand-held, patient-operable device for the delivery of inhalable medicament comprising:
- (a) a housing adapted to be carried by a patient breathing without the assistance of a respirator and sized to fit within the patient'"'"'s hand while said device is in use by the patient;
(b) a monitor for monitoring the breath cycle of a patient positioned within said housing;
(c) a medicament container having a release mechanism releasing inhalable medicament therefrom; and
(d) an actuator for actuating said release mechanism, said actuator being actuable in response to a signal from said monitor,characterized in that the monitor provides said signal at a trigger point which is correlated to the end of the exhalation part of the breath cycle.

Abstract
There is provided a system for the delivery of inhalable medicament comprising a monitor (40) for monitoring the breath cycle of a patient, a medicament container (2) having a release mechanism (4, 5) for releasing inhalable medicament therefrom, and an actuator (50) for actuating said release mechanism, the actuator (50) being actuable in response to a signal from the monitor (40). The monitor (40) provides the signal at a trigger point which is coupled to the end of the exhalation part of the breath cycle.
