Publication number: 20110313364Abstract: An autoinjector includes front and rear separable housing parts 10, 12. These are connected by a rotary coupling action such as by bayonet coupling and the relative rotation action turns a needle shield 20 from a locked position in which it is both locked against longitudinal movement and acts as a shutter obscuring the contents of the syringe to an open position where the contents of the syringe are visible and the shield portion is freed for longitudinal movement. Connecting and securing the rear portion 12 on the front portion 11 therefore unlocks the needle shield 20 for operation. On completion of an injection, uncoupling of the front and rear portions returns the needle shield 20 to its locked position so the front portion may be disposed of safely.Type: ApplicationFiled: December 21, 2009Publication date: December 22, 2011Applicant: OWEN MUMFORD LIMITEDInventors: Steven Mark Guy Rolfe, Max Roland Allen, Jeremy Marshall

Patent number: 7972349Abstract: A housing retains a lancet body which encloses a needle whose tip is covered by a cap. The cap has a head provided with flanges. These flanges locate within notches at the end of the housing on only two sides of the housing. The location of the flanges within the notches holds the lancet within the body, before use, so as to compress a spring positioned between a head and a slotted portion of the housing. When the device is to be used, the head of the cap is rotated through 90° so as to detach the cap from the rest of the lancet body and release the flanges from the notches. This allows the lancet body to be actuated by a sprung-loaded trigger-release mechanism, when required, so that the tip of the needle projects momentarily through the opening at the end of the housing and then bounces back.Type: GrantFiled: August 2, 2004Date of Patent: July 5, 2011Assignee: Owen Mumford LimitedInventors: David Danvers Crossman, Jeremy Marshall

Patent number: 7914546Abstract: Plastics material injected through an entry point of a mould at the location (8) is caused to deflect around a pin which creates the hole (14) in a guard (5), so as to increase the balance of flow of material to either side of the pin (9). In order to minimize the tendency for the plastics material to bend out of shape the tip of the needle embedded within an enlarged portion (13) the mould is formed such that the mould material is initially encouraged to divide and flow through outer thickened regions (10) surrounding a thinner portion. At point (12) the plastics material is therefore caused to slow down resulting in greater equalization of the flow speed of the plastics material to either side of the needle tip.Type: GrantFiled: June 12, 2003Date of Patent: March 29, 2011Assignee: Owen Mumford LimitedInventor: Jeremy Marshall

Publication number: 20100174305Abstract: A return spring arrangement for a lancet (6) is provided by a pair of undulating plastic webs (14) formed integrally with the lancet. The undulations of the two webs (14) are shown out of phase with one another. These webs (14) are flexible and thus are caused to concertina when the tips (15) of the webs hit the interior of a lancet holder on release of a drive spring. The energy stored within the collapsed webs (14) is then released to drive the lancet back within the lancet holder. This positive return of the lancet ensures that a needle (5) will retract safely into the lancet holder, after operation, and does not rely on the spring being locked into the lancet holder and onto the lancet.Type: ApplicationFiled: March 16, 2010Publication date: July 8, 2010Applicant: OWEN MUMFORD LIMITEDInventors: Jeremy Marshall, Mark Eaton

Patent number: 7736343Abstract: A knob is rotated from its zero position to set a dose. This rotates an indexer, which through its peg turns a ring by pushing on one of the teeth. A position is reached wherein the free end portion of the peg meets a cam surface. On continued rotation of the knob, the peg is forced radially inwards to clear the tooth that it has just been pushing against. The ring, having been shifted through one-seventh of a complete revolution is then left stationary while the knob is turned further to whatever dose is required. When a syringe actuation trigger is pressed, the knob winds back again to its zero position, taking with it the indexer. The peg is still held clear of the ring until it hits the sloping side of the tooth following the one which it had previously pushed.Type: GrantFiled: January 10, 2003Date of Patent: June 15, 2010Assignee: Owen Mumford LimitedInventors: Jeremy Marshall, Rury Reginald Holman

Publication number: 20100121272Abstract: 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: ApplicationFiled: January 15, 2010Publication date: May 13, 2010Applicant: OWEN MUMFORD LIMTEDInventors: Jeremy MARSHALL, Nick HANSEN
