Blood lancet device for withdrawing blood for diagnostic purposes, comprising a housing (10), a lancet holder (11), movable within the housing (10), for holding a lancet (4), and a lancet drive to drive the puncturing and retraction movement of the lancet holder (11). At its anterior end in the puncturing direction the housing has an exchangeable skin-contact part (5) on which a contact surface (42) is provided for pressing against the skin when using the blood lancet device (1). The skin-contact part (5) and the lancet (4) form a component of a disposable item (3) which is intended for once-only use and can be inserted at the anterior end (2) of the housing (10) in a single handling operation, said disposable item (3) being designed in such a way that the lancet (4) can be inserted only together with the skin-contact part (5). In order to reliably prevent re-use of all parts of a blood lancet device which could come into contact with the patient's blood, it is proposed that, in the disposable item (3), the skin-contact part (5) and the lancet body (31) made of a plastic material are connected to one another, and at the point of connection between the skin-contact part (5) and the lancet body (31) a first predetermined breaking section is envisaged by means of which the skin-contact part and the lancet body are separable from one another following insertion of the disposable item (3). |
