A needle tip assembly for a pre-loaded syringe or a pen needle injection device, including a needle with a first puncturing end projecting from a front side of a needle support and a second puncturing end projecting from a rear side of the needle support. A body sized to receive therein the needle support and the needle. The body including a front portion, a rear portion, and an overall axial length that is greater than an axial length of the needle. Prior to the needle tip assembly being in an installed condition on the pre-loaded syringe or pen needle injection device, the front portion covers the first puncturing end and the rear portion covers the second puncturing end. Prior to removal from the pre-loaded syringe or pen needle injection device, the body is at least axially movable to a position where the front portion covers the first puncturing end.

The safety syringe assembly is for inserting a needle into a patient and comprises a needle hub assembly and a safety cover. The needle hub assembly includes a needle, needle hub, and hub flex unit. The needle is mounted on the front side of the needle hub while the rear side is for receiving a syringe. The safety cover houses the needle hub assembly in a first position during shipping, a second position during insertion of the needle into the patient, and in a third position after the needle has been inserted into the patient while awaiting disposal. A portion of the safety cover includes magnification enabling a user to view a dosage calibration scale, needle bevel and air bubbles. The hub flex unit assumes a first enlarged position during shipping, is compressed during insertion into the patient, and slides into a third position after usage while awaiting disposal.

The disclosure pertains to a safety syringe having a retractable needle shield which is capable of being retracted to expose the needle for use; being advanced to a needle shielding position; and, if desired, of being removed from the syringe with the shielded needle safely contained within the retractable needle shield via a frangible segment between the syringe barrel and the needle/needle shield components. The disclosure further pertains to a method of using the safety syringe having a retractable needle shield.

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.

A medicament delivery member housing assembly is disclosed that extends along an axis in a longitudinal direction from a proximal end to a distal end. The medicament delivery member housing assembly has a housing, a medicament delivery member, a proximal shield, and a distal shield. The housing can have a body and a flexible arm, the flexible arm extending in the longitudinal direction from a proximal end moveable relative to the body to a distal end attached to the body, wherein the flexible arm has a first surface facing towards the proximal end of the medicament delivery member housing assembly and a second surface facing in a radial direction relative to the axis. The proximal shield extends around a first end of the medicament delivery member, the proximal shield can have a surface facing towards the distal end of the medicament delivery member housing assembly to interact with the first surface of the housing during use.

A needle tip assembly for a pre-loaded syringe or a pen needle injection device, wherein the needle tip assembly comprises a needle mounted to a needle support and comprising a first puncturing end projecting from a front side of the needle support and a second puncturing end projecting from a rear side of the needle support. A body is sized and configured to receive therein the needle support and the needle. The body comprises a front portion, a rear portion, and an overall axial length that is greater than an axial length of the needle. Prior to the needle tip assembly being in an installed condition on the pre-loaded syringe or the pen needle injection device, each of the front portion covers the first puncturing end and the rear portion covers the second puncturing end. Prior to removal from the pre-loaded syringe or the pen needle injection device, the body is at least axially movably relative to the needle support to a position the front portion covers the first puncturing end.
