In general, systems for administering a dmg are provided. In an exemplary embodiment, a dmg administration system includes a dmg administration device configured to communicate with a computer system and at least one sensor configured to obtain sensor data and communicate the sensor data to the drug administration device. The dmg administration device is configured to utilize a first drug dosing scheme when a drug is delivered to a patient, determine a second drug dosing scheme for delivering a drug to the patient dependent on dosing data from the computer system and sensor data collected by the sensor during and/or after the delivery of the first drug according to the first drug dosing scheme, and utilize the second drug dosing scheme when the drug is delivered to the patient.

A method of assembling a drug delivery device, comprising the steps of: inserting a piston rod in a nut portion of a cartridge assembly and rotating the piston rod until the piston rod distal end engages the cartridge piston, mounting a drive member on the piston rod in a rota-tional position being closest to a pre-determined rotational position, and rotating the drive member to the pre-determined rotational position.

The present invention provides a sensor module (50) adapted to be arranged in a cartridge based drug delivery device between a rotatable piston rod and a cartridge piston. The sensor module (50) comprises a first sensor structure (52, 152, 252, 352) adapted to be at least substantially rotationally locked with respect to the cartridge piston and comprising a transversal sensor surface (52.2, 152.2, 252.2, 352.2), and a second sensor structure (53, 153, 253, 353) adapted to be rotationally locked with respect to the piston rod and comprising one or more flexibly supported and axially deflectable contact members (53.1, 53.2, 153.2, 253.2, 353.1, 353.2), which are positioned distally of the transversal sensor surface (52.2, 152.2, 252.2, 352.2) and are adapted to apply a proximally directed force thereto. The first sensor structure (52, 152, 252, 352) and the second sensor structure (53, 153, 253, 353) are adapted to undergo relative rotational motion, whereby the one or more contact members (53.1, 53.2, 153.2, 253.2, 353.1, 353.2) sweep the transversal sensor surface (52.2, 152.2, 252.2, 352.2). A processor (52.5, 152.5, 252.5) determines a relative angular displacement between the first sensor structure (52, 152, 252, 352) and the second sensor structure (53, 153, 253, 353) from signals generated as the one or more contact members (53.1, 53.2, 153.2, 253.2, 353.1, 353.2) sweep the transversal sensor surface (52.2, 152.2, 252.2, 352.2).

In general, drug administration devices configured to communicate with networks and external devices are provided. In an exemplary embodiment, a drug administration device is configured to adjust an operational parameter of the drug administration device based on a data packet formed from drug administration data ancillary data received from networks and/or external devices.
