Single-use blade lancet device includes a body having a rear end and a front end that includes a blade tip opening. A trigger is mounted to the body. A blade member is movably mounted within the body and includes a front end and a rear end. The blade member is movable between a first retracted position, an extended position, and a second retracted position. A biasing arrangement biases the blade member from the first retracted position towards the extended position and then towards the second retracted position. A guiding arrangement 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. During movement of the blade member, the guiding arrangement ensures that blade member maintains substantially the same orientation with respect to the body. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.
