Dry powder inhaler delivery system |
摘要 |
A powder storage and delivery system for a drug powder inhaler has a carrier disk with a blister shell sealed by a shear layer. A tab is adhered to the shear layer, underneath the blister shell. The carrier disk is placed into a dry powder inhaler. An actuator pushes against the tab, causing the shear layer to tear away, releasing the powder drug contents from the blister into the dry powder inhaler. A disk carrier has bursting blisters with a brittle blister shell sealed with a foil lid, and covered by a plate. An actuator moves against the plate, causing the plate to buckle and the blister shell to burst open, releasing powdered drug into the dry powder inhaler. |
