The driving configuration for a drug delivery device comprises an energy storing member (2) providing a force suitable for driving a bung (1) arranged in a container (3), the bung being movable relative to the container. The energy storing member (2) is loaded by an alteration of its mechanical state with respect to a mounting element (5), which is relocatable in such a manner that a force provided by the energy storing member when it is loaded is reduced by a relocation of the mounting element.

A medication injection pen comprises a dose set knob rotatable with respect to a housing to set a desired injection dose. The dose set knob comprises at least one internal thread. A leadscrew includes a thread element for advancing in a first direction via a corresponding thread engagement. A driver is rotationally fixed to the leadscrew and is rotatable in a first direction to rotate and advance the leadscrew in the first direction. The setback member is rotationally fixed to the driver. The dose stop member is rotationally coupled to the setback member and is axially movable relative to the dose set knob when the dose set knob is rotated relative to the setback member. Axial movement of the dose stop member limits the user from setting a dose that is greater than an injectable volume of medication remaining in a cartridge.

The present disclosure is generally directed to a drive mechanism for use in a drug delivery device having a cylindrical cartridge, i.e. a handheld injection device for selecting and dispensing a number of user variable doses of a medicament. The drive mechanism includes a base element, a toothed piston rod, which is guided within and movable relative to the base element, and a drive gear having a pinion, which is rotatably held in the base element and in meshed engagement with the toothed piston rod. The toothed piston rod includes multiple rigid rod pieces which are connected by hinges. The rigid rod pieces comprise a flat plate provided with a straight toothed rack.

A drug delivery system including: an oblong housing including a setting structure to set a dose of a drug via an angular position; and a sensor structure to determine the dose, including a magnet and a magnetic sensor, arranged so that at least one of an angular position and a displacement of the magnetic sensor relative to the magnet may be determined as a function of the electrical resistance of the magnetic sensor. The sensor structure is arranged in relation to the setting structure so that the angular position of the setting structure is determined as a function of the angular position and/or the displacement of the magnetic sensor. A sensor structure is also described including: a flexible foil, including a magnetic sensor, in a cylindrical shape configuration comprising an axis; and a magnet arranged at a line parallel to or collinear with the axis.

A monitoring system comprises: a first device (2) configured to capture an image of a medicament dosage indicated by a medicament dispensing device by an image capturing component of the first device; display the image of the medicament dosage on a display (21) of the first device; and transmit data representing the image of the medicament dosage to a second device; and computer code that when executed by a second device causes the second device (100) to: receive the data representing the image of the medicament dosage sent by the first device (2); perform optical character recognition on the data of the medicament dosage thereby to identify the dosage indicated by the medicament dispensing device; and make a non-transient record of dosage information based at least in part on the identified medicament dosage.

The invention concerns a device for preparing a dose of medicament on demand, comprising at least one receptacle (10), at least one cartridge (12) of a medicinal composition intended to enter said at least one receptacle, the medicinal composition being in liquid or solid powder form, as well as dosing means (14) for dosing said medicinal composition, monitoring means (16) for monitoring the dose of the medicinal composition delivered and control means (18) for controlling the at least one cartridge (12), the dosing means (14) and the monitoring means (16).

A drug delivery device comprising electronic circuitry comprising sensor means adapted to capture a property value related to the dose amount of drug expelled from the reservoir by the expelling means a during an expelling event, storage means adapted to store a plurality of property values to create a data log, and transmission means for wireless transfer of the data log to an external device at a low speed. The transmission means is adapted to listen for and receive a scan request packet whereby the transmission means is operated to wireless transfer of the data log to an external device at a higher speed.

Problem: To provide a liquid-material discharge device that enables easier correction of a changed discharge amount during discharge operation than conventional techniques. Solution: A liquid-material discharge device according to the present invention, which includes a discharging member having a rod-shaped body, a liquid chamber wider than the discharging member, in which a tip portion of the discharging member is disposed, a discharge port communicating with the liquid chamber, a liquid feed path that makes the liquid chamber communicate with a liquid-material reservoir, and a driving device configured to drive the discharging member, includes a discharge amount adjustment member positioned at the liquid feed path, and a member position adjustment mechanism configured to shift a position of the discharge amount adjustment member within the liquid feed path, the discharge amount adjustment member being kept from interrupting communication between the liquid chamber and the liquid-material reservoir.

A device (1) for monitoring the state of an injection applicator comprising an energy source (10) and the following electronic components: an accelerometer (5), a time measuring means (6), a temperature measuring means (7), a processing unit (8) connected to a system adapted to store, process and transfer data, said system including: the time measuring means (6), the accelerometer (5), the temperature measuring means (7) and a memory (9), a user interface (4) connected to the processing unit (8) for presenting information based on the data transferred by the processing unit (8), said monitoring device (1) being connected to a control member (3) of the applicator, and wherein said monitoring device (1) is adapted to operate in a sleep mode and in an active mode, and is further adapted to detect by means of the accelerometer (5) at least a first action and a second action, the first action being related to taking said monitoring device (1) out of the sleep mode and putting it into the active mode, and the second action being related to the setting and/or the delivering of a dose.

In some embodiments, an adjunct device for tracks time and/or dosage of a medicine. The device may include a connector for mounting the device to a deposable pen injector. The device may be configured to allow use of the native controls and injectors of the injector. For example the device may include a view port for viewing a dose indicator of the injector. The device may include one or more vibration sensors. A processor may be configured to differentiate increasing a dose, decreasing a dose and/or discharging the medicine based on the output of the sensors. Optionally a display of the device may be positioned for simultaneous viewing with the dosage indicator of the injector. For example a user may verify the accuracy of the adjunct device before performing a discharge.
