Modular drug delivery device for administering discrete doses of a medicament
First Claim
1. A drug delivery device for providing a plurality of discrete doses of a medicament comprising:
- a disposable delivery unit configured to be worn by a patient, comprising a reservoir for holding a medicament to be delivered, an injection member adapted for trans-dermal drug delivery, a pump for pumping the medicament to be delivered from the reservoir to the injection member, and an outer docking interface; and
a separate reusable base unit configured to be carried separately from the disposable delivery unit between administration of said plurality of discrete doses of a medicament while the delivery unit is worn by the patient and to be temporarily placed in contactless power communication with the delivery unit for administration of said discrete doses of a medicament, comprising a drive module providing power for driving the pump to deliver a dose of the medicament, and a complementary outer docking interface configured for placement against the outer docking interface of the delivery unit, such that the base unit is guided when it is temporarily positioned over the delivery unit for bringing the base unit into electromagnetic or magnetic power communication with the delivery unit without mechanical attachment between the delivery unit and base unit.

Abstract
There provided a drug delivery device adapted for providing a plurality of discrete doses of a medicament including a disposable delivery unit (2) adapted to be worn by a user, comprising a reservoir (10b) for holding a medicament to be delivered, an injection member (22) adapted for trans-dermal drug delivery, and a pump (12) adapted for pumping the medicament to be delivered from the reservoir (10b) to the injection member (22); and a separate reusable base unit (4) comprising a drive module for driving the pump (12). The pump in the disposable delivery unit is activated to deliver a dose of the medicament by bringing the base unit temporarily into communication with the delivery unit.

17. A method of operating a drug delivery device adapted for pumping discrete doses of a medicament, comprising:
-
removably fixing to a patient'"'"'s skin a disposable delivery unit comprising a reservoir for holding a medicament to be delivered, an injection member adapted for transdermal drug delivery, and a pump adapted for pumping the medicament to be delivered from the reservoir to the injection member; placing a separate reusable base unit, comprising a power source and a drive module for driving the pump, temporarily against the delivery unit into electromagnetic or magnetic power communication such that the pump is activated to pump a dose of medicament, without mechanical attachment between the delivery unit and the base unit; and removing the separate reusable base unit from the delivery unit after pumping of the discrete dose of medicament while the delivery unit remains fixed against the patient'"'"'s skin.
