  • Publication number: 20150112262
    Abstract: An autoinjection device includes a main body in the front end of which is slideably mounted a drawer or front body portion. The drawer can be opened to remove or insert a syringe. Closing the drawer whilst pressing a multifunction button primes the drive mechanism by latching it against trigger latch. Pressing the button gain whilst urging the front end causes the drawer to release the trigger latch. After the injection the drawer shrouds the used needle and can be released only by pressing the button.

  • Patent number: 8721593
    Abstract: 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.

  • Publication number: 20140121693
    Abstract: A lancing device includes a housing (10, 12) for receiving in use a replaceable lancet (34) introduced into said housing, a drive (58, 59) actuable to drive the lancet momentarily to project its tip from the housing, and a nose portion (14) having an aperture through which said lancet projects when fired. The nose portion is threadedly engaged (78, 81) with the forward end (10) of the housing to allow the penetration depth of said lancet tip to be pre-set, and is resiliently deformable between a position in which it is locked against rotation and a position in which it is free to rotate.

  • Patent number: 8663265
    Abstract: A lancing device includes a main body having a drive spring, hammer, trigger mechanism and a lancet holder 22. A lancet 34 may be pushed to engage in snap fit with forwardly extending arms 28 of the lancet holder. Whilst free to move axially, the lancet 36 is held against rotation and, following use, is released from the lancet holder by rotating the lancet holder to disengage the lancet from the forwardly extending arms 28 thus freeing the lancet.

  • Patent number: 8500744
    Abstract: A cap used during the insertion of an acetabular cup prosthesis. The cap includes impaction plate having an upperside and an underside. The impaction plate includes a plurality of separate sectors mutually connected at a connection point on the impaction plate by flanges. Each sector includes interlocking elements which in use enable the impaction plate to be connected to an introduction tool. The cap also includes at least one lug extending downwardly from the underside of each sector. The lug is located at the portion of the underside of the impaction plate which will in use enable the lug to be interconnected with a corresponding recess on an internal wall, an external wall or a rim of a prosthesis.

  • Publication number: 20130195540
    Abstract: 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.

  • Patent number: 8460330
    Abstract: 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.

  • Patent number: 8388639
    Abstract: 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.

  • Publication number: 20110202011
    Abstract: 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.
