Abstract:
1. A lancet device comprising a casing, and a lancet supported for reciprocatory movement in the casing between a cocked position and an advanced position, the lancet having a drive head at one end and a projecting needle at an other end, the lancet body having integral webs projecting down both sides toward the location of a tip of the projecting needle, the webs being of undulating form and of a resilient material so as to act as spring members, and a drive spring positioned between the casing and said drive head of the lancet to drive the lancet and projecting needle into an advanced position in which the needle performs a pricking operation and to compress said resilient webs, said resilient webs thereafter serving as return spring members to return the lancet to a position in which the needle is retracted into the casing, wherein, when said lancet is in its cocked position, forward free ends of the webs are spaced from respective abutment surfaces in said casing, and on movement towards said advanced position, said forward free ends engage the respective abutment surfaces to compress said webs.
