Assembly for an autoinjector device

An assembly for an autoinjector device, the assembly including:

• a syringe support for supporting a syringe by limiting forward axial movement of the syringe relative to the syringe support;
• and
• a guard element attachable to the syringe support;
• wherein the guard element is attachable to the syringe support so that the guard element is axially restrained both axially forwardly and axially rearwardly relative to the syringe support,
• wherein attachment of the guard element to the syringe support includes abutment of first abutment features on the syringe support and second abutment features on the guard element;
• wherein forward axial movement of the guard element relative to the syringe support is limited by the abutment of the first and second abutment features;
• wherein forwardly directed axial loads received by an axially rearward surface of the guard element are transmitted to the syringe support via the abutment of the first and second abutment features;
• wherein the second abutment features of the guard element include a plurality of axially forwardly extending legs, and the first abutment features of said syringe support include an external flange, and forward axial movement of the guard element relative to the syringe support is limited by abutment of said plurality of axially forwardly extending legs against said external flange;
• wherein said plurality of axially forwardly extending legs form part of at least a pair of clasps, where each clasp includes a pair of the axially forwardly extending legs and a front cross beam extending circumferentially to connect the two legs of each pair of axially forwardly extending legs;
• wherein the syringe support includes hooks that are configured to latch onto the guard element and limit rearward axial movement of the guard element relative to the syringe support;
• wherein each of said hooks is disposed on an axially rearwardly extending leg of the syringe support;
• and
• wherein the legs of each of said pair of axially forwardly extending legs of each clasp are circumferentially spaced to receive one of said axially rearwardly extending legs of said syringe support.

An assembly for an autoinjector device, the assembly including:

• a syringe support for carrying a syringe installed therein, by limiting forward axial movement of the syringe relative to the syringe support;
• and
• a guard element attachable to the syringe support;
• wherein the guard element is attachable to the syringe support so that the guard element is axially restrained both axially forwardly and axially rearwardly relative to the syringe support,
• wherein attachment of the guard element to the syringe support includes abutment of first abutment features on the syringe support and second abutment features on the guard element;
• wherein abutment of the first and second abutment features prevents forward axial movement of the guard element relative to the syringe support;
• wherein forwardly directed axial loads received by an axially rearward surface of the guard element are transmitted to the syringe support via the abutment of the first and second abutment features without applying axial loading to a syringe carried by the syringe support;
• wherein the axially rearward surface is an axially rearward surface of a flange;
• wherein said guard element defines a central bore extending in an axial direction and the flange extends radially outwardly from the bore;
• wherein said guard element further comprises locating features for co-axially aligning the guard element with the rear end of a syringe;
• and
• wherein said locating features comprise an axially forwardly extending spigot extending from an axially forwardly facing surface of the flange, the spigot defining part of said bore.
