A drug delivery device comprising a delivery unit (2) including an internal reservoir (8), a subcutaneous delivery mechanism (6), a pump for pumping liquid from the internal reservoir to the subcutaneous delivery system, and a liquid filling mechanism (12) configured for injecting liquid from an external vial (16) or reservoir into the internal reservoir. The liquid filling mechanism comprises a filling port (14) and a valve mechanism (18) selectively operable to: open a first fluid path (54) extending from the filling port to the internal fluid reservoir and close a second fluid path (56) extending from the internal reservoir to the subcutaneous delivery member, or close the first fluid path and open the second fluid path. The valve mechanism comprises a valve housing (48) fixedly mounted in relation to a housing of the drug delivery device and a valve stem (50) rotatably received within the valve housing, whereby the first fluid path and the second fluid path are selectively operated by the rotational position of the valve stem in relation to the valve housing, such that when the valve stem is in a first position, the first fluid path is open while the second fluid path is closed, and when the valve stem is in a second position, the second fluid path is open while the first fluid path is closed.

Devices, systems, and methods are provided herein for delivering medication (e.g., insulin) via a wearable pump having a patch-style form factor for adhesion to a user's body. The reusable pump may be coupled to a disposable cap housing a microdosing system for delivering precise, repeatable doses of medication to a cannula configured to deliver medication to a target infusion area beneath the user's outer skin layer. The system further may include an applicator for inserting the cannula into the user's skin and/or applying an adhesive pad to the skin.

The present disclosure relates in one aspect to a measuring arrangement for measuring a volume occupied by a liquid medium inside a liquid reservoir, the measuring arrangement including a container having an interior volume containing a gas reservoir filled with a gaseous medium and containing a liquid reservoir filled with a liquid medium, wherein the gas reservoir and the liquid reservoir are hermetically separated by an impenetrable separation wall, a volume modulator to induce a volume change of the gas reservoir, a pressure sensor arranged inside the gas reservoir to measure a pressure change of the gaseous medium in response to the volume change of the gas reservoir, and a controller connectable to the pressure sensor, wherein the controller is configured to calculate the volume of the liquid reservoir on the basis of the pressure change and the volume change.

The invention concerns an injector device (100), comprising access means (110, 115) configured to selectively allow and prevent a cartridge (120) storing a pharmaceutical product (122) from being removed from the injector device (100), a self-test unit (130) configured to cause a self-test of at least one of an electronic component and an electronic assembly of the injector device (100), and a control unit (140) configured to control the access means (110, 115) to allow the cartridge (120) to be removed from the injector device (100) in case the self-test has failed.

Glucose control systems are disclosed. An ambulatory medicament pump that is configured to wirelessly transmit one or more of a plurality of glucose control parameters and glucose control therapy data to a second ambulatory medicament pump is disclosed. A control system for transferring historical pump data from a first ambulatory medicament pump to a second ambulatory medicament pump is also disclosed. The control system can receive the historical pump data from a first ambulatory medicament pump, determine that at least one of a plurality of pairing conditions is satisfied to connect the data interface to the second ambulatory medicament pump, transmit, via the data interface, a pairing signal to the second ambulatory medicament pump, and transmit at least one of the therapy data associated with the delivery of the glucose control therapy or the glucose control parameter.

An on-body drug delivery device having a housing and a cartridge removably attachable to the housing. The cartridge comprises: a drug chamber, a piston received in the drug chamber movable from a first, initial position to a second position, an actuation device for moving the piston from the first position to the second position, and at least one breakable sterility sensor circuit formed by attachment of the cartridge to the housing, the circuit being closed when the cartridge is properly attached to the housing and broken if the cartridge is not properly attached to the housing or removed from the housing after being attached thereto, and/or the circuit being broken if the piston is not in the initial position when the cartridge is first attached to the housing.

A fluid connector assembly is disclosed. The fluid connector assembly includes a body portion, a plug portion located on the body portion, the plug portion comprising a fluid path, a tubing, a first end of the tubing fluidly connected to the plug fluid path, a catch feature located on a first end of the body portion and configured to interact with a reservoir, and a latching feature located on a second end of the body portion, the latching feature configured to interact and lock onto the reservoir.
