Finger activated lancet device

摘要

A lancet device includes a housing with a cantilever spring extending therein and defining a lancet having a puncturing end on the cantilever spring. An actuator extends within the housing through an opening at the forward end. The actuator includes an interfering engagement with the cantilever spring. Movement of the actuator into the housing through the forward end pivots the cantilever spring against its relaxed condition and then releases the engagement with the cantilever spring, thereby permitting the cantilever spring to pivot the lancet structure to an extended position with the puncturing end extending through the forward opening, and to return to the relaxed condition retracting the puncturing end back within the housing.

主权项

1. A lancet device comprising:
a housing including a forward opening; a lancet structure including a puncturing end; a resiliently flexible member extending from an inner wall of the housing and connected with the lancet structure, the flexible member adapted to pivot the lancet structure between a retracted position in which the puncturing end is maintained within the housing and an extended position in which the puncturing end extends through the forward opening; and an actuator extending through the forward opening of the housing and contacting the flexible member, the actuator including an engagement structure in contact with the flexible member, wherein at least a portion of the flexible member extends through a portion of the actuator to contact the engagement structure, the actuator being movable from a first position extending through the forward opening of the housing to a second position at least partially within the housing to store skin puncturing energy in the flexible member, wherein movement of at least a portion of the actuator into the housing from the first position to the second position releases the engagement with the flexible member, thereby permitting the flexible member to pivot the lancet structure to the extended position to puncture the skin of a user.
