Body fluid sampling device and methods of use
First Claim
1. A method of collecting a bodily fluid sample, comprising:
- forming an incision in skin with an integrated bodily fluid sampling device that has a sampling tube;
projecting an end of the sampling tube from the integrated bodily fluid sampling device after said forming; and
a collecting the bodily fluid sample from the incision with the sampling tube.

Abstract
A device for sampling body fluid includes a housing having a sleeve at a forward end thereof which is displaceable in response to being pressed against a user'"'"'s skin to trigger the firing of a lancet. After the lancet is removed from the incision, the sleeve is repeatedly pressed against the skin to depress a ring of body tissue in surrounding relationship to the incision to express body fluid outwardly through the incision. A pusher member is then actuated to push a capillary tube through a front end of the housing for drawing-in body fluid. The lancet is a disposable lancet which includes a body supporting a skin-lancing member and the capillary tube. The disposable lancet passes through an upper end of a lancet carrier when being installed or removed. The device cannot be armed until the disposable lancet is installed in the housing, because the capillary tube functions to push a safety device to a non-safety position.

10. 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. - View Dependent Claims (11, 12)

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.

16. 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. - View Dependent Claims (17, 18, 19)
