The present disclosure is generally directed to a drug delivery device for selecting and dispensing a number of user variable doses of a medicament and to a non-numerical display for such a device. The display comprises a housing with at least one window, a dosing element movable relative to the housing during dose setting and/or dose dispensing, and a movable indicator element visible through the at least one window The indicator element is coupled to the dosing element and/or to the housing such that it moves not proportional to the dosing element.

An injector for injecting a medicament in a patient. The injector includes a container comprising a fluid chamber containing a first volume of a medicament, and an injection conduit associated with the fluid chamber for defining a fluid pathway therefrom to inject the medicament from the fluid chamber through the injection conduit to an injection location. The injector also includes a firing mechanism associated with the fluid chamber for expelling the medicament from the fluid chamber through the injection conduit, and a volume-control mechanism operable to control a fraction of the first volume of medicament that is injected when the firing mechanism is actuated to inject the medicament.

A dosing mechanism for an injection device includes a dose-setting element with a first element coupled thereto, which, during dose setting, is rotatable relative to a second element about a main rotation axis in a first direction and, during dose discharge, is fixed in rotation relative to the second element. The first and the second elements are coupled via a sleeve-shaped stop element, which forms a stop abutment. The dosing mechanism includes a stop, and the stop abutment, during the rotation of the first element in the first direction, executes a movement to a stop position where the stop abutment strikes the stop and prevents rotation of the first element relative to the second element in the first direction of rotation. The sleeve-shaped stop element is rotatable about a secondary rotation axis, which is offset parallel to or offset at an angle to the main rotation axis.

An assembly for a medication delivery device having a body, a piston rod and a setting nut. The piston rod is rotatable relative to the body in a dose setting state and is axially movable in a distal direction with respect to the body in a dose delivering state. The setting nut is secured against rotational movement with respect to the body, but is axially movable relative to the body, being helically coupled with the piston rod to axially travel in the proximal direction for setting a dose of a medication due to a helical movement of the setting nut with respect to the piston rod when the piston rod is rotated in the dose setting state, and is able to axially travel in the distal direction for delivering the set dose of the medication when the piston rod is axially moved in the dose delivering state of the assembly.

An assembly for a drug delivery device and an associated drug delivery device are provided. The device has a drug delivery device housing and a medicament contained in the drug delivery device housing. A clutch is established between the dose knob and the dial link to prevent inadvertent proximal axial movement of the lead screw away from the cartridge piston, which can lead to dosing inaccuracies.

A dosage limiting device is includes an elongated connecting member that has a plunger receiving head at a first end for capturing a plunger flange of a plunger of a syringe. The plunger receiving head has a back flange connected to the elongated connecting member and a forward slotted flange connected to the elongated connecting member, the forward slotted flange is separated from the back flange by a space sufficient to accept the plunger flange and a flat section of the plunger fitting in a slot of the forward slotted flange. A barrel loop is at a distal second end of the elongated connecting member so that the dosage limiting device limits a dosage provided by the syringe based upon a distance between the plunger receiving head and the barrel loop as the barrel loop abuts a barrel flange of the syringe, thereby limiting extraction of the plunger.

A medicament delivery device configured to provide a variable single dose of medicament is disclosed. The medicament delivery device includes a main body and a syringe arranged in the main body, wherein the syringe comprises a medicament. The medicament delivery device further includes a removable cap and a plunger rod operatively arranged to eject the medicament through a delivery member i.e. an injection needle attached to the syringe. Still further, the medicament delivery device includes a tubular member coupled to the plunger rod. The tubular member is configured to rotate during removing of the removable cap, and the rotation releases the plunger rod thereby allowing the plunger rod to travel a predetermined distance so as to prime the medicament delivery device.

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.

Devices and methods for intraocular fluid injection are disclosed. A device can include a surgical instrument for an ophthalmic procedure. The surgical instrument can include a handle. A fluid compartment can be coupled to the handle and configured to hold a substance. A tool can be coupled to the distal end of the handle and have a lumen configured to convey the substance into an intraocular site of a patient. A piston can be in the handle and configured to reciprocate along the longitudinal axis of the handle to draw the substance from the fluid compartment and eject the substance through the lumen of the tool. A push button can be on the lateral side of the housing and configured to engage the piston via a sloped surface to actuate a forward stroke of the piston towards the distal end of the handle.

A needleless injection system includes a pusher that pushes a plunger within a tapered bore of a cartridge. The pusher includes a nib, the tip of which is a ball.
