A pen needle (10) includes a hub (34) supporting a needle (28) and a distal needle shield (14) that can retract to expose the needle during injection and return to the extended position after use and locked in the extended position cover the needle. A proximal needle shield (16) moves to an extended position with respect to the hub (34) to cover a proximal end (34) of the needle. A spring (64) extends between the distal needle shield (14) and the proximal needle shield (16) to bias each needle shield to the respective extended position. A locking member (78) on the distal needle shield cooperates with the hub to lock the needle shields in the extended position. An indicator (94) in the hub engages and couples to the distal needle shield (14) when moved to the retracted position. The indicator (94) moves with the distal needle shield (14) to the extended position where the indicator is visible through the distal needle shield (14) indicating that the pen needle is no longer usable.

The present disclosure relates to a cap for an injection device. The injection device comprises a body for holding a syringe having a needle extending from an end thereof. The cap is removably attachable to the body. The cap comprises an actuator and a needle shield to cover said needle. The cap further comprises a coupling between the actuator and the needle shield. The coupling is configured such that when the cap is attached to the body of an injection device axial movement of the actuator away from the body causes rotation of the needle shield relative to the body.

Needle shroud assemblies comprising a needle shroud and a support component. At least one of the needle shroud assemblies includes: a shroud body having an inner surface forming a cavity; a shroud beam arranged on the shroud body and biased radially outwards, wherein the support component is arranged on the inner surface of the shroud body and configured to form an inner radial support surface for the shroud body and/or for the shroud beam.

A storage device (30) for storing a pen needle assembly (10) includes a housing (30) having first wells (44) with a dimension for receiving the pen needle assembly and second wells (46) for receiving an inner shield (24) of the pen needle assembly. The second wells (46) have a diameter less than a diameter of the first wells (44). An ejector (40) in the housing (34) can be actuated to eject the used needle hub (16) and outer covers (22) from the first well (44) and the inner shield (24) from the second well (46) for disposal. A method of coupling a pen needle delivery device to a needle hub is also provided.

An insulin injection needle with needle tip protection has a needle body, needle base, main cover and outer sheath. The main cover is provided with the trigger tube, front casing and spring. The trigger tube is used to protect the injection section of needle body before use and the front casing is used to protect the injection section of needle body after use. Before use, the trigger tube extends out of the main cover and is in the state of protecting the needle, and the front casing is in the main cover; after, the trigger tube is in the main cover and the front casing extends out of the main cover and protects the needle. The unlocking of trigger tube and front casing correlate with injection readiness and the tail cover and needle base trigger the unlocking of trigger tube and front casing during the installation.

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.

A rotational locking type safety insulin pen needle comprises a needle body, intermediate shield, front shield and a spring, wherein the intermediate shield has a rotating tube with a beveled rail on the outer edge; the front shield has a bevel acting part on the inner edge; the rotating tube has an elastic arm in the front with a front protection stopper; relative to the front protection stopper, the front shield has a guiding and a limit slot at intervals along the circumferential direction. The backward movement of the front shield when the needle is pushed to drive the rotation of the rotating tube and uses the coordination of the front protection stopper on the rotating tube with the guiding and limit slot on the front shield to change the coordination relationship between the front shield and the rotating tube, which provides the reliable locking protection of the front shield.

A safe insulin pen needle has a structure effectively circumvents the risk of the needle head protection failure caused by the rotation of the insulin pen during the needle pulling process by some users through a first check flange on one side of a first initial fixing position matched with a first elastic clamping jaw. The safe insulin pen needle effectively circumvents the safety risk that the needle tail tends to damage the user through the needle tail protection structure and, at the same time, effectively circumvents the risk that the needle tail protector will rotate and thus the needle tail protection will fail during the separation of the insulin pen from the insulin pen needle through a second check flange on one side of a second initial fixing position matched with a second elastic clamping jaw.

A method of providing and/or injecting octreotide acetate to a subject in need thereof includes storing the octreotide acetate in a cartridge of a multi-use multi-dose injector provided with a variable dose setter and actuator. The injector includes a needle configured for subcutaneous administration of the octreotide acetate, the octreotide acetate having a concentration of 2,500 g/mL. The method further includes providing, on the injector, a plurality of indicia only at prescribed doses of 50 g, 100 g, 150 g and 200 g settable via the dose setter without indicia between said prescribed doses; and permitting setting of a dose of the octreotide acetate by rotation of the variable dose setter, wherein the injector is configured to provide at least one audible feedback during the rotation.

A needle hub assembly for a pen needle includes a needle hub, a cannula or needle coupled to the needle hub, a retractable and compressible sleeve covering at least one end of the cannula, and an outer cover. The outer cover encloses the needle hub and the retractable sleeve. The retractable sleeve is coupled to the hub to cover the end of the cannula where the sleeve can pass through or can be pierced by the cannula and the sleeve retracts axially on the cannula. The sleeve is resilient and returns to an original configuration when an insertion force is released. The needle hub can have a first sleeve to cover a patient end of the cannula, and second sleeve to cover a non-patient end of the cannula where the sleeves retract onto the cannula or hub and expand to the original configuration to cover the ends of the cannula.
