Adjustable disposable/single-use blade lancet device and method
First Claim
1. A single-use blade lancet device, comprising:
- a body comprising a rear end and a front end that includes a blade tip opening;
a trigger at least one of associated with the body and mounted to the body;
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 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 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 blade member maintains an orientation which is substantially parallel to an axis extending from the blade tip opening to the rear end of the body.

Abstract
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.
