Body fluid sampling device and methods of use

A lancet member, comprising:

• a body;
• an incision-forming member extending from said body, said incision-forming member being adapted to form an incision in skin;
• and
• a tube coupled to said body, said tube having an end adapted to move outwardly from said body, said tube having an extended position at which said end of said tube extends past said incision-forming member to collect a bodily fluid sample from the incision.

A lancet member, comprising:

• a body;
• an incision-forming member extending from said body, said incision-forming member being adapted to form an incision in skin;
• a tube coupled to said body, said tube having an end adapted to move outwardly from said body to collect a bodily fluid sample from the incision;
• and
• wherein said body includes:
• at least one lower boss to align said body in a lancet carrier;
• and
• at least a pair of upper bosses disposed at a same elevation above said lower boss to align said body in the lancet carrier, said lower boss and said upper bosses being circumferentially spaced apart from one another along said body.

A lancet member, comprising:

• a body;
• an incision-forming member extending from said body, said incision-forming member being adapted to form an incision in skin;
• a tube coupled to said body, said tube having an end adapted to move outwardly from said body to collect a bodily fluid sample from the incision;
• and
• wherein said body defines a slot in which said tube is received.

A bodily fluid sampling device, comprising:

• a housing including a contact surface for placement against skin in a use position;
• a member coupled to said housing and adapted to form an incision in the skin with said contact surface in said use position;
• a sampling tube provided in said housing, said tube having an inlet opening, said tube having a retracted position with said inlet opening displaced from the skin with said contact surface in said use position, said tube having a sampling position with said inlet opening adjacent the skin with said contact surface in said use position;
• and
• a mechanism positioned proximal said tube to move said tube independently with respect to said member, said mechanism being operable to move said tube from said retracted position to said sampling position while said contact surface is maintained in said use position.
