Embodiment Construction

[0039]Referring to the drawings, a drug delivery device 1 comprises a delivery unit 2 and a base unit 4 . The delivery unit 2 is a single use disposable unit 2 and is detachably connected to a base unit 4 which is reusable with a plurality of successive delivery units. The delivery unit can be used for single administration, or for continuous or intermittent administration over several days. For example, for the administration of a drug such as insulin, the drug delivery device may be configured as a patch device for installation on the patient's skin over a period of days to weeks for basal rate and single administration of the drug. medicine. Once the vial is empty or the delivery unit has reached the prescribed end of life, the delivery unit is discarded and a new delivery unit can be fitted to the base unit for a new dosing cycle.

[0040] The delivery unit 2 comprises a drug flow system comprising a subcutaneous delivery mechanism (not shown) for delivering fluid percut...

Abstract

A drug delivery device (1) comprises a delivery unit (2) in the form of a disposable singleuse part and a base unit (4) in the form of a reusable part for coupling to the delivery unit (2). The delivery unit comprises a liquid flow system for pumping liquid from a drug vial or cartridge (3) received in the drug delivery device to an outlet of the device for transcutaneous administration of a liquid drug, the base unit including at least a power source and an electronic control system, and the delivery unit and base units comprises a releasable locking mechanism including a locking shoulder (30) on the delivery unit that engages a complementary locking shoulder (34) on the base unit. The locking mechanism comprising an unlocking actuator that may be actuated to release the locking shoulder (30) from the complementary locking shoulder (34). The device further comprises a coupling member (8b) on the delivery unit that engages a complementary coupling member (8a) on the base unit, at least one of the coupling member and complementary coupling member comprising at least one elastic arm (10) with a protuberant portion (11) at a free end thereof, the protuberant portion (11) having a rearward ly inclined taper (13) that engages a complementary taper on a complementary protuberant latch portion (12) of the other of said coupling member and complementary coupling member, configured to provide a pulling force (F) between the base unit and the delivery unit to draw them together in a tight fit without play.

Description

technical field [0001] The present invention relates to a drug delivery device for transdermal administration of liquid drugs. In particular, the present invention relates to a drug delivery device in the form of a patch device having reusable and single-use disposable components. Background technique [0002] For example, WO2015015379 describes a drug delivery device, which is installed on the skin of a patient in the form of a patch device for transdermal delivery of liquid drugs. Patch devices for the transdermal delivery of liquid drugs include reusable units and disposable units, typically receiving a cartridge or vial containing the liquid drug to be administered. Liquid medications may be, for example, insulin or other medications that are administered at a basal rate and / or in single doses over a certain treatment period. For such cases, it is known to provide the drug delivery device as two separable parts, a reusable part containing the electronics, power supply ...
