Disposable/single-use blade lancet device and method

Single-use blade lancet device includes a body having a rear end and a front end. A triggering mechanism has a blade tip opening and 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 at least 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.
