Abstract
A lancet device including a housing and a lancet structure having a puncturing tip maintained within an interior cavity of the housing. The device incorporates a bow spring which cooperates with the lancet structure within the housing, and a trigger which extends laterally through and into the housing. The bow spring is resistive to movement, and therefore maintains the puncturing tip in a retracted position within the housing. Lateral movement of the trigger into the housing, such as through a pivoting trigger operation, biases the bow spring against this resistive to deflect the bow spring and extend the puncturing tip through the forward end of the housing to achieve a puncturing position.
Claims25
A lancet device comprising:
- a housing including an opening at a forward end thereof;
- a lancet structure comprising a puncturing end, the lancet structure adapted for movement within the housing between a retracted position with the puncturing end within the housing and a puncturing position with the puncturing end extending through a forward end of the housing;
- a bow spring maintaining the lancet structure in the retracted position in a first state;
- and
- a trigger adapted for lateral movement into the housing,
- wherein lateral movement of the trigger into the housing biases the bow spring from the first state to a second state, thereby extending the lancet structure to the puncturing position.
A lancet device comprising:
- a housing including an interior cavity and an opening through the forward end;
- a lancet structure maintained within the interior cavity of the housing, the lancet structure comprising a bow spring having a puncturing tip extending therefrom, the bow spring in a first state maintaining the puncturing tip in a retracted position within the housing;
- and
- a trigger adapted for lateral movement into the housing so as to bias the bow spring from the first state to a second state thereby bending the bow spring and extending the puncturing tip through the forward end of the housing to achieve a puncturing position.
