LANCING DEVICES
First Claim
1. A lancing device comprising a housing (10, 12), a lancet holder (22) within the housing for receiving in use a replaceable elongate lancet (34) introduced into said housing, a drive (58, 59) actuable to drive said lancet momentarily to project a tip from the housing, a lancet release element (20) for effecting relative angular movement of said lancet holder and said lancet generally about the longitudinal axis of the lancet from a position in which said lancet (34) is retained by said holder (22) and a position in which said lancet is released from said retention.

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.

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

11. A lancing device comprising a housing (10, 12) for receiving in use a replaceable lancet (34) introduced into said housing, A drive (58, 59) actuable to drive said lancet momentarily to project its tip from the housing, and a nose portion assembly (98, 104) mounted on the forward end (10) of said housing, said nose portion assembly comprising a nose portion element (98) slideably and non-rotatably mounted on the forward end of said housing, the nose portion being captive on a rotary collar (104) which is threadedly engaged with the forward end portion of the housing to allow the penetration depth of the lancet tip to be pre-set.
