A drug delivery device is provided having a housing, a lead screw that is rotatably fixed with respect to the housing during dose setting and during dose delivery and that is axially moveable in a delivery direction relative to the housing for dose delivery, a number sleeve threadedly engaged with the housing to be screwable relative to the housing, and a dial link which is axially moveable and rotatable with respect to the housing for dose setting and which is prevented from rotation with respect to the housing for dose delivery. The dial link is rotatably fixed with the number sleeve when the dial link and the number sleeve are in a first arrangement, and the number sleeve and the dial link are rotatable with respect to one another when the dial link and the number sleeve are in a second arrangement.

A server having stored thereon information associated with an identified portable medical device. The server is configured to receive a position and a time point of a client device, and configured to use the position and the time point to retrieve position-specific data for the time point. The position-specific data is used to determine whether the portable medical device should be serviced or replaced.

Medication dispensing apparatuses for dosing-up and delivering a pre-set dosage of a fluid product include a housing; a dosing element moveable relative to the housing between a starting position and a dosed-up position; a drive system coupled to the dosing element operable to initiate or perform a dispensing operation; and a sub-dose preventing system for preventing or blocking a dispensing operation of the drive system when the dosing element has not reached the dosed-up position and for allowing or unblocking a dispensing operation of the drive system when or after the dosing element has reached the dosed-up position, wherein the sub-dose preventing system is operable to block a rotational movement in a circumferential direction of the medication dispensing apparatus of a drive element of the drive system corresponding to a dispensing direction or a dial-down direction when preventing or blocking the dispensing operation of the drive system.

An injector apparatus includes a housing (10.sup.1, 10.sup.2) for a cartridge or syringe, a plunger (40) for cooperating in use with the cartridge or syringe to express successive doses, a dose setting arrangement (16, 20) to select a dose volume, and a drive mechanism (22, 24) releasable to advance the plunger in respective predetermined increments of magnitude to express the successive doses. The drive mechanism includes a drive spring (22) for imparting movement directly or indirectly to the plunger (40), and the dose setting arrangement includes a dose setting element (16) moveable in a dose setting routine to define a magnitude of an increment of movement of the plunger for a given dose. The drive mechanism further includes a clutch arrangement (56) operable during the dose setting routine to inhibit forward movement of the plunger and/or to isolate the dose setting element from the force of the drive spring.

The present invention provides a drug delivery device (1) comprising a drug delivery unit (10) comprising a dose expelling mechanism operable to expel a dose of drug from a drug reservoir (11), a cap (20) configured for dismountable mounting over a portion of the drug delivery unit (10), the cap (20) comprising a cavity (25, 26) for reception of the portion of the drug delivery unit (10), a seal (40) adapted to provide a sealing in an interface between the cap (20) and the drug delivery unit (10), a sensor system (30) configured to monitor internal pressure in the cavity (25, 26) and to register an event in response to sensing a change in the internal pressure which numerically exceeds a specified threshold level over a period of less than 5 seconds, and energy means (50) for powering the sensor system (30).

A button for setting and dispensing a dose of a drug from a drug delivery device is described. The button comprises a plastic component and a metal component, wherein the plastic component is at least partly received by the metal component, and wherein the metal component is configured to be manipulated by a user for setting and dispensing the dose. Furthermore, a method for assembling a button for a drug delivery device and a drug delivery device comprising the button are described.

A dose setting mechanism of a drug delivery device and a respective method of assembling said dose setting mechanism. The dose setting mechanism includes an inner housing having a helical groove along an external surface of the housing. The inner housing includes a rotational stop member near one end of the helical groove. The dose setting mechanism also includes a dial sleeve rotatably engaged with the helical groove of the inner housing. When a user rotates the dial sleeve to select a dose, the rotational stop member prevents the user from selecting a dose greater than a pre-defined maximum selectable dose.

The disclosure relates to an injection device for expelling of a number of preset or user-selectable doses of a medicament. The injection device includes an elongated housing extending along an axial direction and configured to accommodate a cartridge containing the medicament and having a bung sealing a proximal end of the cartridge, a windup expelling mechanism, and a dose setting mechanism. The dose setting mechanism includes a handle, a dose tracking member, and a limiter. The dose tracking member is rotatable relative to the housing within a range of positional states and operatively connectable to the handle for tracking a rotation thereof. The limiter is operationally engageable with the dose tracking member and a trigger of the windup expelling mechanism for blocking actuation of the trigger when the dose tracking member is in one of a number of predetermined sections of the range of positional states.

A server having stored thereon information associated with an identified portable medical device. The server is configured to receive a position and a time point of a client device, and configured to use the position and the time point to retrieve position-specific data for the time point. The position-specific data is used to determine whether the portable medical device should be serviced or replaced.

A mechanism for a drug delivery device includes a body, a dial that is moved with respect to the body for setting a dose, and an indicator member coupled with the dial. A movement of the dial generates a helical movement of the indicator member, and a movable window is coupled to the indicator member.
