Trigger activated lancet
First Claim
1. 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.

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.

15. 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. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)

24. A method of assembling a lancet device comprising:
-
providing a housing defining an interior cavity and including a substantially closed forward end with an opening extending therethrough;
providing a lancet structure comprising a bow spring having a puncturing tip extending therefrom and a trigger integrally molded thereto through a fracturable connection;
inserting the lancet structure into the interior cavity such that the bow spring is maintained within the interior cavity with the puncturing tip directed toward the forward end of the housing and with the trigger extending laterally from the housing; and
fixing the trigger to the housing in a manner so as to provide for lateral movement into the housing upon fracturing of the fracturable connection. - View Dependent Claims (25, 26, 27, 28)

29. A method of actuating a lancet device comprising:
-
providing a lancet device comprising a housing including a bow spring maintained within an interior cavity thereof, the bow spring comprising a lancet structure having a puncturing tip extending toward an opening through the forward end of the housing, the lancet device further comprising a trigger extending laterally from the housing; and
laterally moving the trigger into the housing so as to bias the bow spring from a first state to a second state, thereby bending the bow spring and extending the puncturing tip through the opening in the forward end of the housing to achieve a puncturing position. - View Dependent Claims (30, 31, 32, 33, 34)
