Disclosed are systems and methods of detecting an impulse of energy given off by an injection device and determining a dosage of medicine based on the impulse. In one example, a module detects the vibrations given off by dialing a click-wheel on an autoinjector and determining the selected dosage of medicine based on the dialed dosage.

A micro dosing device is presented for delivering a metered dose of a therapeutic fluid having a dosing unit with a dosing chamber, a connector unit at a distal end for fluidly connecting a medicament container to the dosing chamber, a connector unit at a proximal end for fluidly connecting the dosing chamber to a medicament delivery member, and an activation mechanism, wherein the dosing chamber is configured to receive and therapeutic fluid. Further, the micro dosing device can have a dosing mechanism which provides an exactly metered dose of fluid to be expelled by the medicament delivery member, when the activation mechanism is triggered by a user.

A syringe with an injection dose adjustment function, the syringe comprising a medicine vial connecting apparatus and an adjustable propulsion apparatus; by means of assembling the medicine vial connecting apparatus and a medicine vial, and then installing the adjustable propulsion apparatus in the medicine vial connecting apparatus and extending the adjustable propulsion apparatus into the medicine vial, a rotating knob of the medicine vial connecting apparatus can drive a push rod of the adjustable propulsion apparatus to move backward to a predetermined scale; at a time of injection, pressing the push rod enables the medicine vial to output a predetermined dosage of medicinal liquid, such that the syringe can adjust the dosage of the injection according to requirements of different injection subjects.

The present invention relates to injectors, such as pen-type injectors, that provide for administration of medicinal products from a multidose cartridge and permit a user to set a delivery dose. An injector may include a housing, a cartridge containing a medicinal product, the cartridge being retained within the housing, means for selecting a dose of the medicinal product to be expelled, and means for expelling the selected dose of the medicinal product. The housing may be a unitary housing within which the means for selecting the dose and the means for expelling the selected dose are moveably retained. Alternatively, the injector may include a housing, a piston rod, an insert located in the housing and through which the piston rod may rotate, ratchet means, a dose dial sleeve, a drive sleeve, a button located on the drive sleeve and rotatable with respect to the drive sleeve, and clutch means which upon depression of the button prevents rotation between the dose dial sleeve and the drive sleeve.

A medication delivery device and/or dosing mechanisms suitable for use in medication delivery devices, in particular in pen-type injectors, preferably having a dose setting system and a drive device enabling the administration of a medicinal product from a single- or multi-dose medication cartridge.

A data collection device comprising an attachment assembly for attaching the data collection device to a dose setting dial of a medicament administration device, a light source configured to illuminate a portion of a surface of an internal component of the medicament administration device including a pattern of relatively reflective and non-reflecting regions formed on the surface of the internal component, and an optical sensor configured to receive light reflected by at least the relatively reflective regions.

The invention relates to a disposable drug delivery device for selecting and dispensing a number of user variable doses of a medicament. The device comprises a housing, a cartridge holder for retaining a cartridge containing the medicament, a piston rod displaceable relative to the cartridge holder, a driver coupled to the piston rod, a display member for indicating a set dose and being coupled to the housing and to the driver, and a button coupled to the display member and to the driver.

A drug injection device comprising: a cartridge configured to hold a volume of a drug; one or more processors configured to operate in at least an enabled state and a sleep state, wherein the one or more processors are configured to control an operation of the drug injection device while the one or more processors are in the enabled state; a member disposed in the cartridge, the member including at least two conductive surfaces electrically connected to the one or more processors; and a drive mechanism including a conductive element spaced from the at least two conductive surfaces, wherein the one or more processors are configured to enter the enabled state from the sleep state when the conductive element makes electrical contact with the at least two conductive surfaces.

The present disclosure relates to medicament injection devices. An injection device includes: a movable dosage programming component comprising a rotary encoder system having a predefined angular periodicity, a sensor arrangement including a first optical sensor configured to detect movement of the movable dosage programming component relative to the sensor arrangement during dosing of a medicament, wherein the first optical sensor is configured to operate in a strobe-sampling mode at a first frequency, a second optical sensor configured to detect movement of the rotary encoder system relative to the second optical sensor wherein the second optical sensor is configured to operate in a strobe-sampling mode at a second frequency lower than the first frequency, and a processor arrangement configured to, based on the detected movement, determine a medicament dosage administered by the injection device.

In one aspect the present disclosure relates to a sensor for measuring at least one physical or chemical parameter of a cartridge or syringe filled with a liquid substance. In further aspects the disclosure relates to a cartridge equipped with such a sensor as well as to a drug delivery device equipped with such a cartridge, wherein the sensor comprises: a planar flexible foil arrangeable to an outer circumference of a barrel of the cartridge or syringe, at least a first and a second measuring electrode arranged on said foil, and at least a first and a second contact electrode arranged on said foil, wherein the first contact electrode is connected to the first measuring electrode and wherein the second contact electrode is connected to the second measuring electrode.
