Patent number: 8721593Abstract: An autoinjector is provided with a magnetically operated “injection complete” indicator. A moveable magnet (44) associated with the drive piston (38) is kept at one end of a recess by a soft iron keeper (46) until the drive piston reaches its formal position where the moveable magnet (44) is attracted to impact a magnet (48) on the housing to generate an audible click. Also described is a spring finger (52) that slips behind the rear edge of the syringe boot (50) temporarily to hold the end of the boot well clear of the housing to that it can be gripped for removal.Type: GrantFiled: May 20, 2009Date of Patent: May 13, 2014Assignee: Owen Mumford LimitedInventor: Robert Michael Wozencroft

Publication number: 20130195540Abstract: A fail-safe attachment is provided for coupling an exoskeletal prosthesis to a patient limb having a bone anchored mounting post with an external fixation structure. The fail-safe attachment comprises a first component adapted for connection to the fixation structure, and a second component adapted for connection to the prosthesis. A safety release mechanism is provided normally retaining the prosthesis in a rigid substantially motion-free interconnected relation to the fixation structure, said safety release mechanism responding to a force overload condition to permit relative movement between the prosthesis and the fixation structure. The safety release mechanism comprises a bending force release mechanism responsive to a bending force overload condition to permit the separation of the second component relative to said first component.Type: ApplicationFiled: April 12, 2011Publication date: August 1, 2013Applicant: STANMORE IMPLANTS WORLDWIDE LIMITEDInventors: Robert Michael Wozencroft, Katrina Orme

Patent number: 8460330Abstract: A lancing device includes a main housing 28 having in the forward upper end thereof a loading bay for receiving a capped lancet 12/20. The loading bay is closed by a cover 34 which is pivotally and slideably moveable in the housing. Closing the cover and then pushing it rearwardly causes the lancet body 12 to be pulled rearwardly clear of the cap 20 thereby exposing the lancet needle. Further rearward movement of the shifts the lancet cover into a battery position ready to be driven forwardly by a drive mechanism when fired.Type: GrantFiled: August 14, 2008Date of Patent: June 11, 2013Assignee: Owen Mumford LimitedInventors: Clive Nicholls, Robert Michael Wozencroft

Patent number: 8388639Abstract: A lancet device includes a main body in which is located a lancet drive shaft 20 having a lancet holder 22 at its front end. A front housing flap 12 is hinged to the front of the main body portion and opens to allow insertion/withdrawal of a lancet. A multi-function cocking/ejection element 16 is operable both to cock the drive shaft prior to firing and to eject a lancet from the lancet holder after firing. The cock/eject element also unlatches the front flap 12.Type: GrantFiled: August 14, 2008Date of Patent: March 5, 2013Assignee: Owen Mumford LimitedInventors: Clive Nicholls, Robert Michael Wozencroft

Publication number: 20110202011Abstract: An autoinjection device has front and rear separable assemblies (10) and (12). The rear assembly contains a drive assembly which is triggered or unlatched by rearward movement of an actuating sleeve (14) extending from the front assembly. A locking dial (16) is provided which locks the actuating sleeve against rearward movement until the dial is moved to an unlocked position. The dial automatically returns to a locked position upon initial rearward movement of the actuating member (14), so that, when the actuating member (14) moves forwardly after completion of an injection, it locks out to shroud the needle of the autoinjection device. The docking dial can be made integral with the actuating member (14) in an alternative embodiment.Type: ApplicationFiled: August 28, 2009Publication date: August 18, 2011Applicant: OWEN MUMFORD LIMITEDInventor: Robert Michael Wozencroft
