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, andwherein, during the movement of the blade member, the blade member at least one of;
has a side edge whose distance from the axis changes;
has a side edge whose distance from the axis increases between the first and second retracted positions; and
has a first side edge that moves toward the axis and a second side edge that moves away from the axis.

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.

45. A single-use blade lancet device, comprising:
-
a body comprising a rear end, a front end that includes a blade tip opening, and a sidewall arranged between the front end and the rear end; a trigger; 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 arranged on a side of the blade member and biasing 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, and wherein, during the movement of the blade member, the blade member at least one of; has a side edge whose distance from the sidewall of the body changes; has a side edge whose distance relative to the axis is different in each of the first and second retracted positions; and has a first side edge that moves toward the axis and a second side edge that moves away from the axis. - View Dependent Claims (46, 47, 48, 49)

50. A single-use blade lancet device, comprising:
-
a body comprising a blade tip opening; a trigger; 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 arranged on a side of the blade member and biasing 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 through the blade tip opening, and wherein, a distance between a side of the blade member and the axis is different in each of the first retracted position, the extended position, and the second retracted position. - View Dependent Claims (51)
