A plunger stopper configured for attachment with a plunger rod for use with a within a syringe barrel for high dose accuracy drug delivery. The stopper having a first portion formed from a first material and a second portion formed from a second material, wherein the second material has a greater rigidity than the first material and wherein the second portion is configured to be attached to a plunger rod. The second material can be in the form of an insert which functions to reduce the amount of distortion of the stopper during use, reduce air bubble size variation from fill to fill, maintain a seal with the inner wall of the syringe barrel with lower contact pressure in a resting state and reduce the amount of hysteresis of the stopper. The stopper can be adapted for use with infusers, pens, and other types of auto-injectors.

Systems, methods and devices for administering medication are disclosed. One or more embodiments of a medication delivery device may include a syringe, a needle, a guiding element, and a volume limiter for limiting the amount of medication that can be drawn from a vial. At least one method for administering medication using a medication delivery device, may include: inserting a vial into a guiding element, drawing back on a plunger, removing the guiding element and the vial from a needle to expose the needle, inserting the needle into a patient, depressing the plunger to inject the medication into the patient, and withdrawing the medication delivery device from the patient.

A motorized drug delivery device configured to administer at least one pre-set dose of a medicament contained within a medicament container. The delivery device comprising a user activation system (13), a motor (22), a gear train (15) operatively coupled to the user activation system and the motor, and a piston plunger system (200) operatively coupled to the gear train. The piston plunger system comprises a piston plunger (50) and at least one plunger extension (42; 44) for extending a length of the piston plunger. The piston plunger system is configured to act on a stopper contained within the medicament container to deliver at least one pre-set dose of medicament. The user activation system comprises a mechanical automatic reset activation system for automatically resetting the drug delivery device after administration of the pre-set dose.

A liquid medicament administration device includes a body configured to contain and support a medicament container. The body includes an aperture. The aperture includes a viewing window that is coincident with the medicament container when the medicament container is present. The device is configured such that the viewing window is size-adjustable. Also disclosed are associated methods of manufacture.

A delivery device for delivering a medical fluid to a patient has a housing configured for receiving a container at least partially filled with the medical fluid. The delivery device further has a drive mechanism associated with the housing configured for delivering the medical fluid from the container to the patient in a dosing procedure. The delivery device further has a module configured for detecting at least one of a property of the dosing procedure and a property of the medical fluid. The module has at least one dose detection sensor configured for detecting an initiation, progression, and completion of the dosing procedure based on a position of a stopper within the container. The module further has at least one temperature sensor configured for measuring a temperature of the medical fluid within the container based on a temperature of the container.

Described is an electronics assembly with pressure or force sensing capabilities for use in a drug delivery device. The electronics assembly includes a processor, a sensor arranged to measure the force applied by a drive mechanism to drive a medicament from a cartridge, a wireless module to which an external device can be paired, a power module arranged to supply power to the assembly, and memory storing instructions for the processor to perform. The instructions include receiving a measurement signal during the drug delivery operation, and determining if the dose of the medicament was expelled from the drug delivery device based on the received measurement signal.

The invention concerns an injection device for apportioning set doses of a drug from a reservoir to a subject. The injection device comprises a housing having an interior thread formed as an outwardly pointing thread carried on an upstanding tower centrally located in the injection device. The outwardly pointing thread forms a first thread connection with an interior thread of a rotatable scale drum. The injection device further comprises a driver for moving a piston rod forward when moved axially. The driver operates the piston rod through a second thread connection having a pitch different than the first thread connection.

Methods, systems, and devices are disclosed for administering a medicament to a patient. In one aspect, a system includes an injection pen device in wireless communication with a mobile communication device. The injection pen device includes a housing including a chamber to encase a cartridge containing medicine, a dose setting and dispensing mechanism to set the mechanism to dispense a particular dose of the medicine from the loaded cartridge, a sensor unit to detect a dispensed dose based on positions and/or movements of the dose setting and dispensing mechanism, and an electronics unit in communication with the sensor unit to process the detected dispensed dose and time data associated with a dispensing event and to wirelessly transmit the dose data to a user's device. The mobile communication device provides a software application to provide the user with health information using the processed dose data.

The invention relates to a method for delivering at least one fluid medicament from a medical device. The invention also relates to a medical device. The technical problem of improving the dose accuracy is solved by a method for delivering at least one fluid medicament from a medical device comprising a first reservoir containing a first fluid medicament, a second reservoir containing a fluid, and a fluid element connected to said first reservoir and said second reservoir. The method comprises receiving information about a desired dose of the first fluid medicament to be ejected, adjusting said dose to be ejected from said first reservoir based at least in part on information about a content of said fluid element, and ejecting said adjusted dose from said first reservoir through said fluid element. The technical problem is further solved by a medical device configured to work according to the method.

An add-on logging device (100, 300) mounted to a drug delivery device is turned on when the cap is removed. After a given amount of time in inactivity the sensor means of the add-on device is turned off automatically to save energy. If the user takes a dose of drug this is not detected as the add-on device is only turned on when the cap is removed. According to the present invention a warning message is provided when the cap is re-mounted after the sensor means has been turned off automatically, the warning message indicating to a user that an expelled dose may not have been detected.
