Abstract:
1. A single-use blade lancet device, comprising: a body comprising a rear end and a front end; a triggering mechanism comprising a skin-engaging surface and a blade tip opening, the triggering mechanism being at least one of associated with the body and mounted to the body; the triggering mechanism being movable into the body during triggering; a blade member movably mounted within the body and comprising a front end and a rear end; the blade member being movable at least between a first retracted position, an extended position, and a second retracted position; a biasing arrangement comprising a spring arranged inside the body and spaced from the triggering mechanism and that biases the blade member from the first retracted position towards the extended position and then towards the second retracted position; and a guiding arrangement comprising a guide which guides the blade member while the blade member moves from the first retracted position towards the extended position and then towards the second retracted position, wherein, during movement of the blade member, the guiding arrangement ensures that the blade member both moves along a curved path and slides in a linear direction which is substantially parallel to an axis extending from the blade tip opening to the rear end of the body.
