A needle assembly is disclosed, for use with an injection device. The needle assembly comprises a needle hub () having a needle () and a needle shield () arranged for relative axial movement with respect to the needle hub, between a retracted position in which the tip of the needle projects beyond a forward end of the shield and an extended position in which the tip of the needle does not project beyond the forward end of the shield. The needle shield () is axially biased towards the extended position. The needle shield () is further arranged to be torsionally biased for relative rotational movement with respect to the needle hub ().

Needle assembly

An injection device is disclosed which comprises a housing () for a plurality of cartridges () each containing a medicament to be administered to a patient. A plurality of needles () may be provided in communication with the plurality of cartridges. A delivery mechanism is arranged to deliver medicament through the plurality of cartridges via the plurality of needles. An injection device may comprise a drive member () having a cam surface () configured to engage a surface of a carrier () and rotate the carrier about a pivot () and at least one plunger () arranged to engage a cylinder in the cartridge.

Spring driven injector apparatus with needle insertion

An automatic injection device for delivering a dose from a medicine containing syringe includes a housing for containing the syringe, a force applicator for applying a force to eject medicine from the syringe, a trigger coupled to the force applicator for releasing the force applicator to cause an injection, a boot covering a needle attached to the syringe to protect and maintain sterility of the needle, and a mechanical interlock. The mechanical interlock prevents actuation of the trigger prior to removal of the boot. When the boot is removed, the mechanical interlock allows for actuation of the trigger.

Automatic injection device

A retractable needle assembly comprises a body portion, a needle having a patient end and being movable between an operational position in which the needle extends along a longitudinal needle axis with the patient end projecting forwardly from said body portion, and a safe position in which said patient end is retracted into said body portion, a deflector element rotatable about a deflector rotary axis generally perpendicular to said needle axis to move the needle to its safe position, and a manually operated deflector lever connected to or forming part of said deflector element, the deflector lever projecting from said body portion and intersecting a plane perpendicular to the deflector rotary axis and containing the needle axis.
