Medicament respiratory delivery device and method

A medicament respiratory delivery device, comprising:

• a housing having a chamber therein, said chamber having a chamber inlet and a generally co-axially aligned chamber outlet;
• a medicament cartridge located within said chamber having opposed ends, a passage through said cartridge through said opposed ends generally coaxially aligned with said chamber inlet and chamber outlet of said housing, a medicament in said passage and burstable membranes sealing said passage at said opposed ends of said cartridge having a burst pressure of less than 10 atmospheres;
• a manually actuatable fluid delivery device having a fluid delivery device outlet in fluid communication with said chamber inlet for delivery of fluid under pressure to said chamber;
• and
• a manually actuatable valve located between said fluid delivery device outlet and said chamber inlet having a valve inlet in fluid communication with said fluid delivery device outlet and a valve outlet in fluid communication with said chamber inlet;
• whereby actuation of said manually actuatable fluid delivery device delivers fluid under pressure to said valve inlet and opening of said valve delivers fluid under pressure to said chamber inlet, thereby rupturing said burstable membranes of said medicament cartridge and expressing said medicament through said chamber outlet.

A medicament respiratory delivery device, comprising:

• a medicament dosing member including a chamber having a chamber inlet and a chamber outlet generally co-axially aligned with said chamber inlet;
• a medicament cartridge located within said chamber having opposed ends, a passage through said cartridge through said opposed ends generally coaxially aligned with said chamber inlet and chamber outlet of said medicament dosing member, a medicament in said passage and burstable membranes sealing said passage at said opposed ends of said cartridge having a burst pressure of less than 10 atmospheres;
• a fluid delivery device including a tubular barrel having a barrel outlet in fluid communication with said chamber inlet, a plunger located within said barrel manually movable from a first position within said barrel to a second position toward said barrel outlet, thereby compressing fluid within said barrel at said barrel outlet and said barrel and said plunger including cooperative stop members retaining said plunger in said barrel when said plunger is moved in said barrel to generate sufficient fluid pressure within said barrel at said barrel outlet to rupture said burstable membranes;
• a valve located between said barrel outlet and said chamber inlet having a valve inlet in fluid communication with said barrel outlet and a valve outlet in fluid communication with said chamber inlet;
• and
• a stop member fixing said plunger in said barrel at said second position;
• whereby movement of said plunger from said first position to said second position compresses fluid in said barrel at said barrel outlet and opening of said valve delivers fluid under pressure to said chamber inlet, thereby rupturing said burstable membranes of said medicament cartridge and expressing said medicament through said chamber outlet.
