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.

An electronic device comprising: a housing for attachment to an injection device; a first sensor assembly comprising a first coil and two magnets of opposite polarity, wherein the first coil is configured to provide a first voltage pulse as a first Wiegand wire of the injection device moves from a first position proximate to one of the magnets of the first sensor assembly to a second position proximate to the other magnet of the first sensor assembly; and one or more processors configured to enter an enabled state from a sleep state after receiving the first voltage pulse from the first coil.

A kit is disclosed for accurately loading a small volume dose of a medication within a syringe and for delivering the small volume dose of the medication at a treatment site. The kit generally includes a loading and delivery system in accordance herewith, a syringe, and a medication. The loading and delivery system includes a syringe delivery ring and a syringe loading guide, which may be used for example, to administer a small volume dose of a medication at the end of an ocular surgery.

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.

A syringe exostructure includes a main body which removably receives a syringe having a syringe barrel and a syringe plunger. A drive plunger is reciprocatably mounted on the main body, and a plunger bar is slidably received in an axial channel on the drive plunger. The plunger bar is configured to removably couple to the syringe plunger when the syringe is introduced into the main body. A drive pawl assembly is fixed to an upper surface of the drive plunger and transfers forward motion of the drive plunger to the plunger bar as the drive plunger is advanced and disengages from the plunger bar when the drive plunger is retracted. A locking pawl assembly is fixed to the main body and extends through a slot formed in the bottom of the axial channel in the drive plunger. The locking pawl engages the plunger bar and allows the plunger bar to be advanced by the drive plunger as the drive plunger is advanced but prevents the plunger bar from being retracted by the drive plunger as the drive plunger is retracted.

An example injector includes a rotary knob for selecting a function and setting a dosing quantity for an injection, a button located on an end of the rotary knob for initiating the injection, an electric motor, an encoder for evaluating output rotary motion of the motor, and a processor that converts the dosing quantity into a number of encoder pulses and controls operation of the motor based on the number of encoder pulses when dosage is triggered. The injector also includes a transmission coupled to the electric motor to convert a speed of the motor, a threaded spindle coupled to the transmission that moves linearly based on the output rotary motion of the motor at the speed as converted by the transmission, and a punch connected to an end of the threaded spindle. The linear movement of the spindle causes the punch to release medicament.
