Abstract
A skin pricker has a body (1) with a spring-loaded lancet holder (4) with a forward facing socket (20) to receive the rear end of a lancet. The socket (20) is radially expandable/compressible and the spring-loading is a coil spring (5) part of which embraces the socket and tends to close it up. This allows lancets of slightly varying diameters to be firmly held. The pricker is primed by pressing a lancet into the socket (20), which urges the holder (4) back to be releasably held by a trigger mechanism (3, 9).
