A needle tip (22) for being connected and disconnected in use from a needle tip support (16), comprises a needle (24) having a forward end and a rearward end and, a connector secured to the needle intermediate its ends. The connector comprises two arms (28) each extending outwardly and rearwardly relative to the needle (16) and configured to be coupled and uncoupled in use from said needle tip support, and the arms are disposed on opposite sides of the needle. Also disclosed are arrangements for storing, dispensing and later disposing such needle tips, as well as coupling interfaces between the needle tip and a needle support cap to which it is fitted in use.

A needle actuator assembly for a drug delivery system includes a needle actuator body having a guide surface, a needle shuttle having a cam surface, with the needle shuttle moveable along a vertical axis between a first position and a second position. The needle shuttle is configured to move between the first and second position through engagement between the guide surface of the needle actuator body and the cam surface of the needle shuttle. The assembly further including a needle received by the needle shuttle.

A multiple carrier injection system (10) comprising an adapter (20) including at least one arm (22), a pen needle assembly (29) including a hub (30) retaining a needle (44), and a bullet (50) having a cover (58) to seal the bullet (50), the bullet (50) enclosing the hub (30) in a first position, wherein the arm (22) engages the adapter (20) to the hub (30), and the arm (22) causes the hub (30) to rotate within the bullet (50) to move the hub (30) into a second position.

A drug delivery device with a housing configured to connect to a dispensing unit including a compartment containing a fluid, a piston rod configured to move in a proximal direction for ejecting the fluid, and a dosing mechanism including an actuation member to be actuated by a user. The device includes a conversion mechanism configured to convert a movement of the actuation member to a movement of the piston rod. The conversion mechanism includes a dose selector member, which is rotationally fixed to the housing and axially movable with respect to the housing, and a dosing member, which is rotationally movable with respect to the dose selector member. The drug delivery device includes a friction reduction mechanism provided between the dose selector member and the dosing member to reduce friction between the dose selector member and the dosing member.

Disclosed herein are pressure control systems, comprising: a touch screen electrically connected to industrial computer or embedded operating system; a pressure output channel connected to the touch screen and/or the industrial computer or embedded operating system; and pressure control unit for communicating with the pressure output channel, wherein the pressure control unit can be controlled with the touch screen, and wherein the industrial computer or embedded operating system comprises preinstalled software with User Interface (UI) for pressure control setup and running the system.

The needle shuttle is configured to move between the first and second position through engagement between the guide surface of the needle actuator body and the cam surface of the needle shuttle. The assembly further including a needle received by the needle shuttle.

The invention relates to a safety device for avoiding stabbing injuries, for a syringe having a syringe body and a piercing means arranged on the distal end of said syringe body. The safety device comprises a sleeve element that extends in an axial direction (X) and encloses at least partly the piercing means and the syringe body, and a collar element that is arranged on a distal end region of the syringe body and locks the safety device in the axial direction (X), said collar element having at least one guide projection which is guided in at least one guide track of the sleeve element during a movement of the syringe body relative to the sleeve element substantially in the axial direction. The safety device is characterised in that the collar element is arranged on the distal end region of the syringe body so as to be rotatable in a circumferential direction (U) and has at least one tolerance compensating element which is in operative contact, mechanically, with the syringe body so that tolerances of the syringe body can be compensated for.

An automatic injection device including a housing, a chamber with a first compartment and a second compartment, and a seal structure between the compartments. The seal structure is initially in a sealing condition that seals the first compartment from the second compartment, where the seal includes a plug and an outer sealing member. The plug is slidably movable within the outer sealing member to convert the seal structure from the sealing condition to a mixing condition by opening a path between the first compartment and the second compartment. The automatic injection device also includes a needle assembly and an activation assembly. Activation of the activation assembly causes (1) pressurization of the first compartment, (2) the seal structure to convert from the sealing condition to the mixing condition, and (3) the first and second medicament components to be mixed and forced through the needle assembly.

An apparatus includes a housing coupled to a medicament container, which is coupled to a needle. An injection assembly is disposed within the housing and includes an energy storage member and an actuation rod. A distal end portion of the actuation rod is disposed within the medicament container. The energy storage member can produce a force on a proximal end portion of the actuation rod sufficient to move the distal end portion of the actuation rod within the medicament container. This can convey at least a portion of a substance from the medicament container via the needle when a distal tip of the needle is disposed within a first region of a target location. The force is insufficient to move the distal end portion of the actuation rod within the medicament container when the distal tip of the needle is disposed within a second region of the target location.
