Abstract
A lancet device has a two part housing (1) integrally molded in a folded-out configuration with a spring (2), a lancet body (3) encasing a needle (4), and a needle cap (5) concealing the needle tip. The spring (2) is a zig-zag connected at one end to one housing part (7) by a web (19) and merging at the other end into the lancet body (3). This is folded over with the spring (2) about the web (19) into the housing part (7), and the other housing part (6) is closer over about web hinges (8) and fastened. A trigger (9) is incorporated in the other housing part (6) and is deformable inwardly to release the lancet body (3) from a catch arrangement (14, 21) which holds the lancet retracted with the spring energized. The needle cap (5) can be used for the retraction before being removed.
