A medicament delivery device is presented that has a manually operable activator element, an activator blocker operably arranged to the activator element, where the activator blocker defines at least one locking member. A medicament delivery device housing is included having at least one flexible hook, wherein the at least one flexible hook of the medicament delivery device housing is operably between a locked position and an unlocked position. In the locked position the flexible hook is releasably engaged with the at least one locking member of the activator blocker, thereby preventing operation of said activator element and in the unlocked position the flexible hook is out of engagement with the at least one locking member of the activator blocker, thereby allowing operation of said activator element.

A drug delivery device includes a magnet assembly, a coil assembly and processing circuitry. The magnet assembly has a plurality of magnets arranged in a ring. The coil assembly has one or more coils. The magnet assembly and the coil assembly are arranged to rotate relative to each other during ejection of medicament from the drug delivery device such that a voltage signal is produced in the coil assembly when a unit of dose is ejected. The processing circuitry is arranged to: receive the voltage signal; increment a counter in response to receipt of the voltage signal; and store information indicative of the number of units of dose ejected during a medicament ejection.

An autoinjector for dispensing a liquid product, in particular a highly viscous medication, includes: a housing, a product container, which is arranged in the housing and has a slidable piston, wherein the piston can be slid in a dispensing direction in order to dispense the product contained in the product container, a forward drive element, which acts on the piston as the product is being dispensed, a first spring, which is preloaded such that the product can be dispensed from the product container by the sliding of the forward drive element and the piston, and a rotation element, which is operatively coupled to the forward drive element, wherein the first spring acts on the rotation element in such a way that the rotation element is set into rotation in order to dispense the product, wherein the rotation element or the forward drive element has a thread having a variable pitch.

The syringe dispenser includes a syringe and a plunger. The plunger includes a first shaft member including a piston and second shaft member configured to be fitted in a tubular portion of the first shaft member. The first shaft member includes an elastic piece, the elastic piece being provided with a slide projection configured to slide on an inner surface of the syringe and a lock projection configured to be locked against the syringe. The second shaft member includes a pressing shaft configured to be fitted in the tubular portion. The pressing shaft is provided in a front end thereof with an end surface configured to press a free end of the elastic piece. In response to pressing from the end surface, the lock projection is locked against the rear end of the syringe, and in response to the pressing being released, the locking of the lock projection is released.

A fluid delivery device comprises a fluid reservoir for containing medicament. The fluid reservoir is sealed proximate one end with a sliding seal piston. A delivery path is configured to fluidly couple the fluid reservoir and a patient wearing the fluid delivery device. A basal engine mechanism is configured to directly or indirectly move the sliding seal piston in the fluid reservoir at a controlled basal rate. A bolus mechanism configured to move the basal engine relative to the fluid reservoir and directly or indirectly move the sliding seal piston in the fluid reservoir a discrete bolus amount at a time.

The invention relates to an autoinjector for dispensing a liquid product, in particular a highly viscous medication, comprising: a housing, a product container, which is arranged in the housing and has a slidable piston, wherein the piston can be slid in a dispensing direction in order to dispense the product contained in the product container, a forward drive element, which acts on the piston as the product is being dispensed, a first spring, which is preloaded such that the product can be dispensed from the product container by the sliding of the forward drive element and the piston, and a rotation element, which is operatively coupled to the forward drive element, wherein the first spring acts on the rotation element in such a way that the rotation element is set into rotation in order to dispense the product, wherein the rotation element or the forward drive element has a thread having a variable pitch.

Single use hydraulic drive devices and single use large volume injectors are described. A method for single use hydraulic drive including releasing a holding device to move a catalyst coated portion of a rod into a reagent filled chamber, generating pressure in the chamber due to at least one of gas creation and thermal expansion from a chemical reaction between the catalyst coated portion and the reagent, hydraulically displacing a moveable object in hydraulic communication with the chamber, and stopping further chemical reaction when the pressure exceeds a holding device force threshold to enable the holding device to re-hold a retracted catalyst coated portion of the rod outside of the chamber. The self-regulating pressure in the chamber enables a controlled rate of hydraulic displacement of the moveable object.

The present invention relates to a finger grip (1) arranged to be connected to a syringe barrel having a plunger and a plunger rod for driving said plunger. The finger grip comprises a body having a lower side with finger supporting surfaces (13) for supporting fingers of a user during handling and an engagement member (5) being moveable between an inactive position where the engagement member is arranged not to engage with the plunger rod of the syringe barrel and an active position where the engagement member is arranged to engage with a grooved surface on the plunger rod of the syringe such that feedback is given to a user as the plunger is moved relative to the finger grip. An activation member (7) for moving the engagement member from said inactive position to said active position is built-in into the finger grip.

The present invention provides a system (1) comprising: a pen injection device (10) holding a specific type of medicament and comprising a dose expelling mechanism and pen communication means (15), a mobile communication unit (30) comprising mobile communication means (35) adapted to communicate with the pen communication means (15), and a software application program configured to determine a recommended type of medicament to be delivered to a user based on information indicative of a physiological condition of the user, wherein the pen injection device (10) further comprises indication means which in a first state indicates that the dose expelling mechanism is to remain idle and in a second state indicates that the dose expelling mechanism is available for operation, and wherein the mobile communication unit (30) is configured to, via a communication from the mobile communication means (35) to the pen communication means (15), a) prompt a change of state of the indication means from the second state to the first state in response to the recommended type of medicament to be delivered differing from the specific type of medicament, and/or b) prompt a change of state of the indication means from the first state to the second state in response to the recommended type of medicament to be delivered corresponding to the specific type of medicament.
