The present invention relates to a drug delivery device for setting and dispensing of a dose of a medicament is presented comprising a housing to accommodate a cartridge filled with the medicament, an electrically operated drive mechanism to be operably engaged with the cartridge to expel a predefined dose of the medicament from the cartridge, and at least one dose element displaceably arranged relative to the housing to set and/or to dispense the dose of the medicament, wherein the dose element and the drive mechanism are mechanically decoupled from each other.

A force actuated injection device including a body adapted to contain medication, a grip slidably disposed over the body, a lock disposed between the body and the grip, the lock when locked preventing movement of the grip relative to the body and when unlocked permitting movement of the grip relative to the body, a needle guard retractable relative to the body, a biasing member biasing the needle guard away from the body, and a resistance band disposed between the body and the needle guard adapted to resist initial needle guard retraction relative to the body, wherein force on the needle guard exceeding a predetermined amount overcomes a frictional force of the resistance band allowing the needle guard to retract relative to the body to unlock the grip relative to the body such that movement of the grip relative to the body causes medication to be delivered from the body.

An auto-injector device including a syringe, a needle arranged in the vicinity of a first end of the syringe, and a plunger arranged within the syringe. A volume within the syringe between the plunger the needle accommodates medicine, such that movement of the plunger toward the needle dispenses medicine through the needle. A selection assembly configurable by a user to adjust an amount of medicine dispensed by the auto-injector device and depth to which the medicine is delivered. Also, a method for treating a skin lesion or skin disorder utilizing the auto-injector and a kit for patient administered treatment.

The present disclosure relates to an assisted injection device for injecting a composition contained in a medical container. The injection device includes a main body adapted to receive a medical container in a fixed position relative to the main body. The main body includes an inner wall part and a second part. The first part includes an inner spring-loaded piston rod, and an outer piston body extending coaxially around the inner spring-loaded piston rod. The second part is arranged between the inner spring-loaded piston rod and the outer piston body, and is provided of the piston. The actuator is adapted to selectively move the second part between the proximal first portion and the distal second position.

A cap for intake and delivery of a fluid from a syringe is described. The cap includes an outer cap assembly comprising a fluid inlet path and a fluid outlet path and an inner cap assembly configured for innertion into a fluid nozzle of the syringe and to provide selective fluid communication between an interior of a syringe and the fluid inlet path or the fluid outlet path. The outer cap assembly is slidable relative to the inner cap assembly between a first filling position, where the interior of the syringe is in fluid communication with the fluid inlet path, and a second delivery position, where the interior of the syringe is in fluid communication with the fluid outlet path. The outer cap may further slide, relative to the inner cap assembly, to a third closed position where the interior of the syringe is fluidly isolated from the fluid inlet path and the fluid outlet path. Syringes including the cap are also described.

An auto-injector device including a syringe, a needle arranged in the vicinity of a first end of the syringe, and a plunger arranged within the syringe. A volume within the syringe between the plunger the needle accommodates medicine, such that movement of the plunger toward the needle dispenses medicine through the needle. A selection assembly configurable by a user to adjust an amount of medicine dispensed by the auto-injector device and depth to which the medicine is delivered. Also, a method for treating a skin lesion or skin disorder utilizing the auto-injector and a kit for patient administered treatment.

An injection device for holding and actuating a pre-filled syringe including a barrel holder having an axial passageway adapted to hold the barrel of the pre-filled syringe, a grip movable relative to the barrel holder to move a plunger of the pre-filled syringe, the grip configured to be locked to the barrel holder to prevent axial movement therebetween and unlocked from the barrel holder to permit axial movement therebetween, and a needle guard arranged to retract into the barrel holder in response to force against an injection site to unlock the grip from the barrel holder.

A pen-type drug injection device is disclosed which comprises a housing having a longitudinal axis, a threaded piston rod, a guide member for guiding the piston rod in a drug dispense operation, and a cartridge holder for receiving a cartridge, wherein the cartridge holder is detachable from the housing and wherein the guide member comprises an iris type aperture defined by a plurality of threaded pivotable segments. The drug delivery device is configured such that the aperture increases in diameter when the cartridge holder is being detached from the housing, such that the piston rod is free of the threaded engagement with the guide member and can be reset or pushed back to its initial position, and decreases in diameter when the cartridge holder is attached, such that the threads on segments reengage the piston rod.

A mini syringe includes a tubular base member, a microneedle unit including a microneedle device and a compressible pharmacy housing device and mounted in the bottom side of the base member, a plunger mounted in the base member and pressable to compress the pharmacy housing device, and an adjustment cover threaded onto the base member for controlling the moving distance of the plunger in a micro-adjustable manner.

The mechanism includes a body, a drive member movable in the body, a main spring that is loaded when a dose is set and is released for moving the drive member during a delivery of a dose, and a movable trigger inhibiting a movement of the drive member, a movement of the trigger releasing the main spring and the drive member. The trigger is moved from a start position to an end position relative to the body during a setting of a dose, the end position having a distance from the start position that increases as the dose set increases.
