摘要： Disclosed is an auto-injection apparatus for receiving a syringe, including: an outer casing enclosing a drive assembly and a syringe carrier configured to hold a barrel of the syringe, the syringe carrier being forward of the drive assembly and having stowed and delivery positions; an interlock extending between the syringe carrier and a syringe carrier housing at least partially surrounding the syringe carrier, the interlock preventing forward motion of the syringe carrier under the influence of an insertion actuator whilst in the stowed position. The drive assembly includes the insertion actuator for inserting a needle of the syringe into an injection site and a delivery actuator for driving a plunger into a barrel of the syringe which contains a substance for injection. The syringe carrier includes an interlock release mechanism which is configured to release the interlock such that the insertion actuator drives the syringe carrier forward.

摘要： An injection device is disclosed comprising a plunger for expressing medicament from a syringe and a delivery mechanism arranged in use to provide a forward biasing force to urge the plunger from a first rearward position to a second forward position to express a dose from the syringe. A latch arrangement is provided that releasably holds the plunger against the force of the de livery mechanism. The latch arrangement comprising at least two resilient segments which define opposing sections of an aperture within which a rearward end of the plunger is retained in the rearward position. A trigger is provided for releasing the plunger in use, the trigger being arranged to outwardly deflect at least one of the resilient segments such that the aperture is expanded to release the rearward end of the plunger. A method of manufacturing the injection device is also enclosed.

摘要： The invention relates to an injection device comprising an elongate housing and a cap removably mounted over a forward end of the housing. The cap comprising at least one slot extending forwardly from its rear edge; the at least one slot being configured to engage with an outwardly projecting protrusion on an outer surface of the housing when the cap is mounted on the housing. A rearward portion of the cap includes rearwardly extending engagement features provided on each side of the at least one slot, the engagement features being configured to locate within a cavity in the housing when the cap is mounted on the housing. The cavity is provided with corresponding surfaces which align with the cap engagement features so as to hold the outwardly projecting protrusion within the cut-out.

摘要： An injection device for delivering a dose of medicament from a syringe (5), the injection device comprising a housing (10), a plunger (210) moveably mounted within the housing (10), an actuation mechanism (200), a trigger mechanism (40), and a plunger velocity regulator. The actuation (mechanism (100) is arranged to provide a forward biasing force to urge the plunger (210) forward in use to express a dose of medicament, and the trigger mechanism (40) is arranged to releasably hold the plunger (210) against the force of the actuation mechanism (200). The plunger velocity regulator comprises a cam surface (262) associated with the housing, and a cam member (252) associated with the plunger (210) and arranged to engage the cam surface (262) during actuation movement of the plunger (210) such that axial movement of the plunger (210) relative to the housing (10) causes relative rotational movement of the cam member (252) which limits the forward velocity of the plunger movement. The plunger (210) is axially connected to the cam member (252) by a releasable coupling (300), and the plunger velocity regulator further comprises a coupling member (350) which blocks release of the releasable coupling (300) when the plunger (210) is in a rearward position and wherein forward movement of the plunger (210) moves the releasable coupling (300) out of engagement with the coupling member (350) such that the plunger (210) may disengage the cam member (252) after an initial movement of the plunger (210).
