The device further comprises a first detector for detecting movement of the stop wheel relative to the housing and/or the at least one sleeve and a data processing unit connected to the first detector reading, storing, processing, transmitting, and/or displaying signals received from the first detector.

A system, a detection device, a method, a use, and a computer program product for monitoring an actual or simulated preparation, performing, and/or post-processing of a dispensing—referred to as dispensing process below—of an administrable, preferably pharmaceutical, substance, with a dispensing device for dispensing the substance, whereby the dispensing device has at least one sound generator, which is designed in the dispensing process to generate at least one sound event, specific to a property or change in state of the dispensing device, in an acoustic signal, and with a detection device for checking the acoustic signal for the at least one sound event, in order to make possible a detection of the property or change in state of the dispensing device.

A medicament dispensing mechanism is disclosed that is configured to eject successive doses of the medicament from a medicament chamber. An embodiment of the dispensing mechanism includes a housing and a plunger rod configured for ejecting the doses of medicament from the chamber. The dispensing mechanism further includes an actuation mechanism that comprises a trigger associated with the housing and having a ready and a fired position with respect thereto. The trigger is configured for manipulation by a user for successive movement in a generally axial dosing motion from the ready position to the fired position in which the trigger is associated with the plunger rod to cause the plunger rod to eject one of the doses of a predetermined volume and a resetting motion from the fired position to the ready position that comprises axial rotation, wherein the trigger is uncoupled from the plunger rod during the resetting motion.

An automatic medication injection device that provides a user with audible notice of injecting progress. The device in one form includes a plurality of sound elements located on drive mechanism portion that inserts within a barrel of a container of medication to advance a sealing plunger of that container. The device also includes at least one actuating element movable axially with the container of medication within the device housing, which at least one actuating is element arranged to engage the plurality of sound elements to generate audible notices as the advancing portion moves past the at least one actuating element when advancing the sealing plunger for an injection.

A medical device and system for the administration of a medical substance or for dosing body fluids comprising a rotor, rotating around an axis X-X, operatively connected to an injection device of said medical substance, and a rotor locking/unlocking device mechanically separate from the rotor and integral in rotation therewith. The locking/unlocking device comprises, in one piece, a disc, centered with respect to said axis X-X, from which a plurality of flexible fins radially unravel. The flexible fins are configured to flex around transverse hinges at a connection portion with the disc, and are angularly spaced so as to define gaps between adjacent pairs of fins which prevent interferences between adjacent fins in the respective flexing movement. The flexible fins are associated with ferromagnetic means for the operation of the same fins and locking/unlocking means of the rotation of the disc. The disc and fins are formed from a single plastic body.

The present invention provides a drug injection device (100) comprising a first element (140) and a second element (103) configured to undergo unidirectional movement relative to each other corresponding to an action performed on or by the drug injection device (100), wherein the first element (140) comprises a plurality of serially disposed protrusions (143), wherein the second element (103) comprises first and second deflectable transducers (103a/153a, 103b/153b) configured for sequentially cooperating with the plurality of protrusions (143), and wherein a processor (151) is electrically connected with the first and second deflectable transducers (103a/153a, 103b/153b) to register activation signals, wherein the protrusion configuration is so disposed on the first element (140) and the first and second deflectable transducers (103a/153a, 103b/153b) are so disposed on the second element (103) that a second activation signal generated by the second deflectable transducer (103b/153b) is delayed relative to a first activation signal generated by the first deflectable transducer (103a/153a) as the first element (140) and the second element (103) move relative to each other, and wherein the processor (151) is configured to provide a) a first control action if a time delay between the first and second activation signals is above or equal to a pre-defined value, and b) a second control action if said time delay is below said pre-defined value.
