A needle assembly for mounting on an injection device which comprises a body configured to be attached to an injection device in use; a double ended needle and a needle shield coupled to the body. The needle shield is arranged for axial movement with respect to the body. The needle assembly has an injection configuration, in which the shield is positioned such that the forward tip of the needle projects beyond a forward end of the shield. The needle assembly also has a shroud configuration, in which the shield is positioned such that the forward end of the shield extends beyond the forward tip of the needle. The needle assembly further comprises a needle support fixed relative to the body when the needle assembly is in the injection configuration. Movement of the shield from the injection configuration to the shroud configuration axially displaces the needle support relative to the body.

A needle protection device () for protecting a needle has a needle carrier () for carrying said needle () and being translatable along a longitudinal axis X between a first, deployed, position (D) and a second, protected, position (P); a shuttle () surrounding said needle (); a hub () for receiving the needle carrier (); a sleeve () being rotatable around each of said needle carrier (), said shuttle () and said hub (); a first driving mechanism () between said needle carrier () and said shuttle () to cause axial displacement of said shuttle () in a first direction (A) between a first, retracted position R and a second, deployed position Ds upon axial displacement of the needle carrier () along axis X; and a second driving mechanism () between said needle carrier () and said sleeve () to cause axial displacement of the carrier () in said first direction (A) upon rotational displacement of the sleeve ().

Needle cover

A needle assembly for mounting on an injection device which comprises a body configured to be attached to an injection device in use; a double ended needle; and a needle shield coupled to the body. The needle shield is arranged for axial movement with respect to the body. The needle assembly has an injection configuration, in which the shield is positioned such that the forward tip of the needle projects beyond a forward end of the shield. The needle assembly also has a shroud configuration, in which the shield is positioned such that the forward end of the shield extends beyond the forward tip of the needle. The needle assembly further comprises a needle support fixed relative to the body when the needle assembly is in the injection configuration. Movement of the shield from the injection configuration to the shroud configuration axially displaces the needle support relative to the body.

A method of manufacturing a skin pricking lancet includes: thermoforming a plastic component; locating the thermoformed component and, optionally, one or more further plastic components around a lancet mechanism; and joining the located component(s) to form a hermetically sealed enclosure surrounding the lancet mechanism, the component(s) being formed and joined to provide a housing that structurally supports the lancet mechanism during use, and a cap breakable from the housing to facilitate firing of the lancet mechanism.

A retractable needle assembly () is disclosed comprising a body portion (); a needle () having a forward end () and being movable between an operable orientation in which the forward end projects forwardly from the body portion, and a safe orientation in which said forward end () is retracted into the body portion (). The needle assembly further comprises a deflector () mounted in the body portion (), which is moveable between a first position and a second position, wherein the movement of the deflector () between its first and second position urges the needle into its safe orientation, the deflector being biased towards the second position; a latching mechanism which holds the deflector in the first position; and an actuator (), operable to release the latching mechanism.

Retractable needle assemblies

A needle assembly () for mounting on an injection device is disclosed comprising: a main body () which is removably attached to an injection device in use; a needle () secured in the main body and having a forward portion which projects forwardly from the main body. The needle assembly further includes a shield () which is slideably mounted within the main body () and an actuator portion () which extends outside the main body and is configured for pushing the shield () forward manually in use. The shield () is slideably moveable between a first position in which the forward portion of the needle () projects forwardly of a shield cavity (), and a second position in which said forward portion of the needle is located within the shield cavity (). The shield () and main body () are provided with cooperating features comprising at least one latching element () provided on one of the shield () or the main body () and at least one corresponding engagement feature () provided on the other of the shield () and the main body. The latching element () moves into a latched position as the shield () moves into the second position to hold the shield in its second position.

Needle assemblies

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.
