Claims12
A medicated module configured for use with a drug inhaler (2), the medicated module comprising:
- a housing (5) configured for removable attachment to a drug inhaler (2), where the housing has a distal end and a proximal end;
- a removable cap (4);
- a reservoir (20) containing a dose of medicament, where the reservoir has a first seal (21) and a second seal (7);
- wherein the first seal (21) is configured to be opened by attachment of the medicated module to a drug inhaler (2);
- and
- wherein the cap (4) is operatively connected to the second seal (7) such that removal of the cap removes the second seal from reservoir (20).
The medicated module of any preceding claim where the reservoir (20) is positioned within the housing at an angle in the range of from about 60 to 120 degrees measured relative to an axis defined by the cannula so that the medicament from reservoir (20) is drawn into a reservoir chamber (32).
The medicated module of any preceding claim where the reservoir (20) is configured as a venturi injector.
The medicated module of any preceding claim further comprising a slider (30) for opening a seal connected to the reservoir (20) when the slider is moved in a distal direction.
The medicated module of any preceding claim further comprising a reservoir activation mechanism (23), wherein the reservoir activation mechanism (23) is movable relative to the housing (5) from a first position when the medicated module is not in an attached condition to a second position when the medicated module is in an attached condition.
An inhaler drug delivery system comprising, in combination,
- a medicated module of any preceding claim;
- and
- a pressurized metered dose housing (2) comprising a reservoir (10) of compressed fluid.
