This disclosure relates to pre-filled syringes and their methods for use and injection. The embodiments provide a pre-filled syringe system for controlled depth of injection in a subject, including a pre-filled syringe having a needle tip and a plunger for injecting the contents of the pre-filled syringe; a housing for holding the pre-filled syringe and needle tip in a defined position for a depth of injection; and a needle shield mounted on the housing for releasable movement from a locked injection position to a shield position, wherein after the needle shield is moved into the locked injection position with the needle tip extended out of the needle shield and pre-filled syringe system, the needle can be inserted into the subject at a defined depth of injection. The embodiments further provide methods of injecting a subject using a pre-filled syringe system, including providing a pre-filled syringe system having a housing, a needle shield mounted on the housing, and a pre-filled syringe with a needle tip; moving the needle shield mounted on the housing into a locked injection position to extend the needle lip of the pre-filled syringe and system at a defined length out of the needle shield and prc-filled syringe system; inserting the needle tip of the pre-filled syringe and system into a subject at a defined injection depth, and injecting the contents of the pre-filled syringe and system into the subject.

A cannula arrangement includes a cannula support and a cannula held thereon. A distal flow-through channel end section of a flow-through channel of the cannula support has a stepped cross-sectional shape as seen in axial section, with multiple mutually different cross-sectional dimensions decreasing in the axial direction. Each one of the cross-sectional dimensions defines its own receiving section for the respective cannula to be received therein. Each one of the cross-sectional dimensions of the receiving sections is embodied to receive the cannula with a corresponding cross-sectional cannula dimension in each case.

An injector device includes a housing for receiving a medicament cartridge; a needle unit comprising a needle; and a first sleeve slideable along a longitudinal axis of the housing from a first position, in which the first sleeve conceals the needle, to a second position, in which the needle is exposed from an end of the first sleeve, the first sleeve configured to engage the needle unit so that, during use, movement of the first sleeve from the first position to the second position moves the needle unit from a primary position to a secondary position, in which secondary position the needle unit locates over an end of a medicament cartridge, wherein the device further comprises a second sleeve arranged to move telescopically with respect to the first sleeve, the first sleeve extending from the second sleeve when the first sleeve is in the first position.

Medicament delivery device comprising a movable guard (10) being movable between a proximal and a distal position and a locking mechanism (15) having a level (16), the lever (16) restricting movement of an actuation locking member (24) until the movable guard is positioned in a distal position and the lever (16) restricting movement of the guard (10) in a proximal position after actuation of the device.

An auto-injector for administering a dose of a liquid medicament (M) is presented having an elongate case, a carrier subassembly comprising a tubular carrier slidably arranged inside the case, where the carrier adapted to contain a syringe with a hollow injection needle. The injector also has, a drive spring and a plunger for forwarding load of the drive spring to a stopper of the syringe, wherein the syringe is lockable for joint axial translation with the carrier. A control spring is arranged around the carrier for translating the carrier in a proximal direction (P) for advancing the needle beyond a proximal end of the auto-injector, and a trigger button is used for releasing the control spring on actuation.

Systems and methods are disclosed for processing sensor data collected by a drug delivery device with an external computing device. The drug delivery device may include a reservoir and a delivery cannula having a proximal end in fluid communication with the reservoir and a distal end to be received within a patient. The drug delivery device may further include one or more sensors configured to generate sensor data representative of a condition and/or operational state of the drug delivery device, and a communication module configured to transmit information to the external computing device. The external computing device may process the information received from the drug delivery device according to information stored in a memory of the external computing device to determine the condition or the operational state of the drug delivery device and/or generate instructional or informational prompts to be displayed to a user or patient.

A safety needle device is disclosed having a housing configured to couple to a syringe, the housing having a proximal end, a distal end, and a housing body. A first guide path, a second guide path and a third guide path may be disposed on the housing body. A needle hub is disposed on the proximal end of the housing and a needle cannula is attached to the needle hub. The device having a retractable sheath configured to move between an initial position, a retracted position and an extended position with respect to the housing, wherein the initial position partially exposes a distal tip of the needle cannula, the retracted position fully exposes the needle cannula, and the extended position fully covers the distal tip of the needle cannula. The retractable sheath also may have a guide element. The first, second and third guide paths are configured to slidingly receive the guide element. The device also having a first locking member, a second locking member, a rotating cam disposed in the housing body, and a spring element to bias the retractable sheath to an extended state to cover the distal end of the needle cannula upon completion of an injection.

A spring clip needle tip shielding device for arrangement in a catheter hub of an intravenous catheter assembly is provided. The spring clip needle tip shielding device comprises a base plate with a hole extending therethrough and at least one resilient arm extending at an attachment point at said base plate. The at least one resilient arm has a resting state, from which it may be urged to yield free passage through said hole in an axial direction of said base plate in a tension state, said at least one resilient arm being adapted for clamping a needle tip of a needle extending through said hole when said resilient arm is in said resting state. Any straight imaginary line extending longitudinally through said hole in the axial direction of said base plate coincides with said at least one resilient arm when said resilient arm is in said resting state of said body. The spring clip needle tip shielding device is of a rigid material, and at least a part thereof is coated with a solid lubricant. A catheter assembly including such shielding device is also provided.
