摘要： The present invention is concerned with a drug delivery device with a rigid cannula, a soft cannula and an automatic needle or cannula insertion mechanism. A novel design of a cannula assembly uses a sealing sleeve to ensure a fluid-tight slidable connection between the soft cannula and the rigid cannula with improved sealing pressure while allowing damage-free, cost-effective manufacturing.

摘要： Systems and methods for driving electrical motors of medicament infusion pumps are disclosed. An infusion device for delivering a medicament to a body of a user can include a reservoir to contain medicament, a dispenser to cause medicament to be moved out of the reservoir, and a motor operably coupled to the dispenser. The motor can include a stator defining a central opening and a rotor removably disposed therein. A controller coupled to the stator is configured to (1) supply a first signal to the stator to cause the rotor to rotate in a first direction for a first rotational amount less than a full rotation; and (2) to then supply a second signal to the stator to cause the rotor to rotate in a second, opposite direction for a second rotational amount greater than the first, thereby causing medicament to be dispensed from the reservoir via the dispenser.
