Inhaler Device

摘要

A device (20) is disclosed for dispensing a fluid supplied from an external fluid source. The device comprises a transducer (32) adapted to receive a fluid from the fluid source, and a collapsible linkage and trip link (502) coupling the transducer and the fluid source. The linkage has a collapsible joint inhibiting discharge of the fluid source when in a locked orientation. The device (20) further comprises a moveable member coupled to the linkage such that inhalation forces on the device cause the linkage to collapse thereby discharging the fluid from the fluid source. The device may further include a dose counter coupled to the fluid source for registering the amount of doses administered from the fluid source.

1. An inhaler for dispensing metered doses of a medicament, the inhaler comprising a housing, an actuator member (508) moveable relative to the housing; a first link member (504) for coupling with a container of medicament; and a restraining surface (514) connectable with the first link member (504) for restraining movement of the first link member (504) from a first position, in which the medicament container is located in a stowed configuration, to a second position, in which the medicament container is located in a discharge configuration so as to dispense medicament; wherein the restraining surface (514) is moveable from a restraining position in response to movement of the actuator member (508) from a nominal position so as to allow movement of the first link member (504) from the first position to the second position; characterised in that the inhaler further comprises an elastically and resiliently deformable member (36) arranged adjacent the actuator member (508) so as to be compressed and thereby bias the actuator member (508) towards said nominal position.
