Patent number: 8449498Abstract: An injection device for a syringe incorporates housing for a syringe. A needle shroud is captive to the leading end of the housing and is movable before use between extended and retracted positions. A drive member is releasable from a rearward position within the housing to urge the syringe forwards to project its needle beyond the retracted needle shroud and then to express a dose through the needle. Locating members on the housing capture the drive member at its forward position (attained after expressing the dose). The captured drive member is also arranged to block retraction of the needle shroud from its extended position.Type: GrantFiled: January 15, 2010Date of Patent: May 28, 2013Assignee: Owen Mumford LimitedInventors: Jeremy Marshall, Nick Hansen

Patent number: 8425460Abstract: A needle shroud assembly for a syringe holder comprises a barrel (16), a needle shroud (24) captively telescoped relative to the forward end of the barrel (16) and retained by a top outer body (44). A locking ring (42) cooperates with the shroud, having diametrically opposed keyways which are brought into and out of axial alignment with keys (38) on the shroud (24) to free or lock the shroud from movement. The locking collar (42) is biased towards a ‘safe’ position. On cocking the locking ring (42) to a ‘live’ position the shroud (24) is freed for retraction movement but on return to its extended position, the locking ring is returned to its ‘safe’ position.Type: GrantFiled: September 1, 2006Date of Patent: April 23, 2013Assignee: Owen Mumford LimitedInventor: Toby Cowe

Patent number: 8425547Abstract: A lancet body for a skin pricker has resiliently flexible fingers (9) with outwardly splayed tips (10). The device is fired by pressing a trigger (13) and a spring (5) urges the lancet forwards and the fingers (9) flex inwards as the tips (10) snap past barbs (11), so that the tips (10) of the arms (9) engage behind the barbs (11). If the user tries to push the lancet back into the cocked condition, the fingers (9) are trapped and will flex as the tips (10) press against the barbs (11) until the arms buckle and the tips (10) are pushed out through openings (14). Thus the lancet is arrested and immobilized before a re-cocked position is reached, and re-firing is prevented.Type: GrantFiled: March 9, 2004Date of Patent: April 23, 2013Assignee: Owen Mumford LimitedInventors: Jeremy Marshall, Adam John Mumford

Publication number: 20130035645Abstract: An injection device includes a cap (38) which is withdrawn from the front of the device before use to remove a boot (52) from the needle (50). The cap (52) has fingers (46) which grip the boot and which pass down a passage through which the needle projects to inject a dose. The passage has projections disposed to reduce the effective bore of the passage, the projections having inwardly inclined resilient portions which allow the boot to be withdrawn forwardly through the passage but prevent a finger being poked into the passage.Type: ApplicationFiled: March 4, 2011Publication date: February 7, 2013Applicant: OWEN MUMFORD LIMITEDInventors: Stephen Bicknell, Alan Peel

Patent number: 8343109Abstract: When a trigger of an injection device is released, a main spring (4) expands, driving a member (7) forwards. This compresses a weak spring (11), but a spring (5) is stiff enough to remain expanded. A syringe (2) is thus thrust forwards via a collar (9), so that a needle (3) projects from a barrel (1). The spring (4) continues to expand after the syringe has reached its forward position, with the spring (11) fully compressed, so that the stem (8) of the member (7) acts on a piston (14) within the syringe (2), to expel the dose while the spring (5) is caused to be compressed. The spring (5) ensures that the syringe is retained in its forward position during this phase.Type: GrantFiled: March 5, 2003Date of Patent: January 1, 2013Assignee: Owen Mumford LimitedInventors: Jeremy Marshall, David Danvers Crossman

Patent number: 8337472Abstract: A sheath remover device is of elongate tubular form having a sheath capture region at one end and a passage along which a captured sheath may pass from the capture region. A plurality of latching fingers, each with an internally directed latch, are equi-spaced in the capture region. Two further inwardly directed latches are on the cut out regions. The sheath remover is designed so that, a sheath already disposed in the sheath capture region is pushed along the passage away from the sheath capture region when the remover is offered up to and engages the subsequent sheath. The spacing of the latches and is such that the earlier sheath is not released from latches until the latches have securely engaged in the subsequent sheath, thereby providing an indication of secure engagement of the subsequent sheath. The sheath remover may also be used as a cap and/or a cocking rod.Type: GrantFiled: December 31, 2008Date of Patent: December 25, 2012Assignee: Owen Mumford LimitedInventors: Alex Edginton, Christopher William Hudson
