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;
a triggering mechanism comprising a blade tip opening, the triggering mechanism being 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 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.

Abstract
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. 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.

19. A disposable and single-use blade lancet device, comprising:
-
a body comprising a rear end and a front end; a cap member arranged at the front end of the body and comprising a blade tip opening; 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 that is different than the first retracted position; a biasing device that causes movement of the blade member from the first retracted position towards the extended position and then towards the second retracted position; and a guiding arrangement that at least comprises first and second projections, a connecting member movably coupled to the first projection and a portion of the body, and a slide movably coupled to the second projection and slidably engagable with another portion of the body, wherein the 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.

20. A disposable and single-use blade lancet device, comprising:
-
a body comprising a rear end and a front end; a trigger device having a blade tip opening and being 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 portion and a rear portion; the blade member being movable 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 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 the guiding arrangement comprises a slide which linearly guides the front portion of the blade member and a connecting member which guides the rear portion of the blade member along a curved path.
