The present disclosure relates to a dose detection system for use with a medication delivery device in which a dose setting member rotates relative to an actuator during dose delivery. The dose detection system includes a module which is removably attached to the medication delivery device. The module includes a rotation sensor attached to the actuator during dose delivery. A sensed element is attached to the dose setting member and includes surface features detectable by the rotation sensor. The rotation sensor comprises a following member including a contact portion resting against and spring-biased in the direction of the surface features. The contact surface is positioned to move over the surface features during rotation of the sensed element, and the rotation sensor is responsive to the movement of the contact portion over the surface features to detect the rotation of the dose setting member.

Injection monitoring circuitry is provided for coupling to part of an injection device having a syringe and a plunger rod. The injection monitoring circuitry has an input to receive force measurement data from a force sensor, the force measurement data includes a plurality of timestamped force measurements of force applied by a user to the injection device when an injection is administered to an injection site. Processing circuitry is provided to determine from the force measurement data when an end of injection has been reached, the end of injection corresponding to the plunger rod having reached an end position in a distal portion of the barrel of the syringe during administration of the injection by the user. Machine readable instructions and an injection monitoring method are also provided.

A sliding cover for a liquid delivery device, such as a cap (100) for a pen injector (200), incorporates a set of sensors including an optical sensor (110) with an output which changes during uncapping or capping motions on passing of a plunger (220) of the pen injector. This output is used together with a position sensor (120) to determine the position of the plunger along a cylinder (210) of the liquid delivery device. By monitoring changes in the plunger position, the quantity of dosages delivered by the liquid delivery device can be determined, displayed, stored and/or transmitted to an external device for further data processing or storage. Preferred implementations of the invention employ optical sensors with a converging beam (115), and/or position sensors employing linear potentiometer strips (132).

A fertility kit for performing self-insemination, comprising a package with three sets of sterilized disposable syringes and collection jars. Each fertility syringe comprises: an outer rigid tubular barrel and an inner plunger. The barrel comprises a curved distal end with a small circular distal opening, and a sealed proximal end, and an inner hollow tube housing the plunger. The barrel's proximal end also comprises two opposing circular members to fit a user's fingers; and a plunger flat end fitting in-between. The plunger distal end has a has a funnel-like shape that fits into the barrel curved end to push all the semen out while preventing a backflow. The collection jar comprises a sealable lid, and an inner surface comprising smooth seamless edges. Fresh or frozen, unwashed semen is deposited into the jar, pulled into the syringe, and administered cervically during a user's maximum monthly level of luteinizing hormone.

Implementations of the present disclosure are directed to conserving energy of an injection device that includes an energy source configured to power an electronic component, a priming component configured to generate a trigger, a reactant configured to generate an instantiation signal in response to the trigger, and a sensor configured to detect and process the instantiation signal and generate an activation signal to activate the energy source.

The disclosure relates to a detector arrangement for detecting a position of an object with regard to a first direction, wherein the object includes a front edge and a rear edge separated from each other in the first direction and wherein the object is movable relative to the detector arrangement in the first direction. The detector arrangement includes a first detector configured to detect electromagnetic radiation, the first detector including a first detection area sensitive to the electromagnetic radiation, wherein the detection area is confined by a first detection front edge and by a first detection rear edge, wherein the first detection front edge is separated from the first detection rear edge in the first direction. At least one of the first detection front edge and the first detection rear edge extends non-parallel to at least one of the front edge and the rear edge of the object.

A system comprising a wireless data communication accessory and a drug delivery device is disclosed, wherein the wireless data communication accessory is configured for data exchange with the drug delivery device and to secure data from the drug delivery device using cryptographic information assigned to the drug delivery device.
