Lancet device with depth adjustment and lancet removal system and method

A lancet device comprising:

• a housing;
• a removable front cap mounted to the housing;
• lancet holding means for holding a removable lancet, the lancet holding means extending along a longitudinal axis of the housing, the lancet holding means comprising a front section having a front end that receives therein the removable lancet, a midsection and a rear section;
• a releasable arming system comprising a trigger in communication with the front section of the lancet holding means, the trigger structured and arranged to hold the lancet holding means in a trigger-set or armed position;
• a lancet penetration depth adjustment system comprising a cam surface that engages with the lancet holding means to limit axial movement of the lancet holding means to a corresponding puncturing position;
• a lancet ejection system located closer to a front end of the housing than to a rear end of the housing and adjacent to the front section of the lancet holding means, said lancet ejection system comprising a slide member, wherein the slide member comprises:
• a lancet remover portion at a front end of the slide member that removes or ejects the removable lancet from the lancet holding means by contact of a front edge of the slide member with a back end of the removable lancet loaded in the lancet holding means;
• a rear projection;
• and
• a slide button manually activatable by a user;
• and
• a plurality of springs comprising:
• a first spring that interfaces with the midsection of the lancet holding means, the first spring configured to cause movement of the lancet holding means towards the corresponding puncturing position when released from the trigger-set or armed position;
• a second spring that interfaces with the rear section of the lancet holding means, the second spring configured to cause a back cap to move towards an initial position from a retracted position;
• and
• a third spring configured to contact the rear projection to cause the slide member of the lancet ejection system to move towards an initial position from an extended position when the slide button is manually activated by the user, thereby providing removal of the removable lancet from the lancet holding means.
