Blood lancet device for obtaining blood samples for diagnostic purposes, comprising a housing (10), a lancet holder (11) which is movable in the housing (10) for mounting of a lancet (4), and a lancet drive for driving the puncturing and withdrawal movement of the lancet holder (11). At the front end in the puncturing direction the housing has an exchangeable skin contact member (5) provided with a contact surface (42) for pressing it on to the skin during use of the blood lancet device (1). The skin contact member (5) and the lancet (4) form part of a disposable part (3) intended for single use and insertable in a handling step at the front end (2) of the housing (10). The disposable part (3) is designed such that the lancet (4) can be inserted only together with the skin contact member (5). In order to rule out reliably any re-use of any component of a blood lancet device that could come into contact with the blood of the patient it is proposed, according to the invention, that the skin contact member (5) and the plastic lancet body (31) in the disposable part (3) are connected to form a unit and that a first intended breaking point, via which the skin contact member and the lancet body can be separated from one another after insertion of the disposable part (3), is provided at the connection point between the skin contact member (5) and the lancet body (31). <IMAGE> |
