Contact activated lancet device

A lancet device comprising:

• a housing comprising a forward housing body and a rear housing body, the rear housing body having a rearward end;
• a lancet structure comprising a puncturing element, the lancet structure disposed within the housing and adapted for movement between a pre-actuated position wherein the puncturing element is retained within the housing and a puncturing position wherein the puncturing element extends through a forward end of the housing;
• a biasing member biasing the lancet structure toward the puncturing position;
• a retaining hub retaining the lancet structure in the pre-actuated position against the bias of the biasing member, the retaining hub comprising a lever pivotal about a fulcrum comprising a class 1 lever, the lever providing interference engagement with the lancet structure, the lever having a first contact surface;
• and
• an actuator adapted to pivot the lever, thereby releasing the lever from interference engagement with the lancet structure, permitting the biasing member to drive the lancet structure toward the puncturing position, the actuator having a second contact surface,
• wherein the forward housing body and the rear housing body mate at a position substantially peripheral to the retaining hub within the housing, and wherein movement of the actuator toward the lever such that the second contact surface contacts the first contact surface to cause the lever to pivot out of engagement with the lancet structure, wherein the pivoting of the lever moves the lancet structure toward the rearward end of the housing to at least partially compress the biasing member and release the interference engagement between the lever and the lancet structure.

A lancet device comprising:

• a housing;
• an internal contact disposed within the housing;
• a lancet structure comprising a puncturing element, the lancet structure disposed within the housing and adapted for movement between a pre-actuated position and a puncturing position wherein the puncturing element extends through an end of the housing;
• a biasing member in cooperation with the lancet structure for biasing the lancet structure toward the puncturing position;
• and
• a lever element pivotal about a fulcrum comprising a class 1 lever for providing interference engagement with the lancet structure and retaining the lancet structure in the pre-actuated position and adapted to retain the lancet structure against the bias of the biasing member,
• wherein movement of the housing toward the lever element causes the internal contact to contact and pivot a portion of the lever element about a pivot point and release of the interference engagement between the lever element and the lancet structure, permitting the biasing member to drive the lancet structure through the housing toward the puncturing position.

A lancet device comprising:

• a housing;
• a lancet structure comprising a puncturing element, the lancet structure disposed within the housing and adapted for movement between a pre-actuated position and a puncturing position wherein the puncturing element extends through an end of the housing;
• a biasing member in cooperation with the lancet structure for biasing the lancet structure toward the puncturing position;
• and
• a lever element pivotal about a fulcrum comprising a class 1 lever for providing interference engagement with the lancet structure and retaining the lancet structure in the pre-actuated position and adapted to retain the lancet structure against the bias of the biasing member,
• wherein movement of the housing toward the lever element causes pivotal movement of the lever element to at least partially compress the biasing member and release the interference engagement between the lever element and the lancet structure, permitting the biasing member to drive the lancet structure through the housing toward the puncturing position.
