A lancet has a needle (2) embedded in an elongate plastics body (1) with its tip (6) concealed in a cap (4) integrally moulded with the body (1) but connected only through a narrow neck (5) which enables the cap (4) to be twisted and broken free of the body (1), exposing the needle tip (6). The cap (4) has a central aperture (8) and is adapted to fit the forward end of a firing device for the lancet, once freed from the body (1). The cap (4) then serves as a platform against which a finger to be pricked is pressed, the needle tip (6) projecting momentarily through the aperture (8). The cap (4) may be reversible, and be fitted to the firing device either way up. |
