1. A body fluid sampling device, comprising:
- a meter;
a lancing device configured to create an incision in a surface of tissue, wherein the lancing device includes a lancet;
a fluid detector configured to detect sufficiency of body fluid bled from the incision while on the surface of the tissue;
an analysis device configured to analyze the body fluid once the fluid detector detects that the body fluid on the surface of the tissue is sufficient for analysis, wherein the analysis device includes a test strip;
an integrated lancing test strip including the lancet attached to the test strip;
the integrated lancing test strip being detachably coupled to the meter, the lancet and test strip of the integrated lancing test strip being configured to be removed together from the meter as a single unit;
wherein the fluid detector includes one or more sensors disposed on the integrated lancing test strip to detect sufficiency of the body fluid bled from the incision while on the surface of the tissue;
the test strip defining a capillary channel with a capillary channel opening for drawing the body fluid; and
the test strip having the one or more sensors integrated into the test strip at the capillary channel opening.

Abstract
A bodily fluid sampling device is operable to breach the skin surface and allow bodily fluid to emerge from the breach location. The bodily fluid sampling device further evaluates the amount of bodily fluid emerged from breach location and determines whether the amount is sufficient or insufficient for a particular purpose, such as sampling and testing. The determination is accomplished automatically without moving the device. The user may also intervene to perform a variety of tasks following the determination of the amount of bodily fluid.

12. A body fluid sampling device, comprising:
-
a test strip including a capillary channel for drawing body fluid from tissue and an analysis portion located along the capillary channel for analyzing the body fluid; a lancet coupled to the test strip for creating an incision in the tissue; wherein the lancet is coupled to the test strip in a slidable manner to allow extension of the lancet from the test strip; the test strip has a fluid detector to sense sufficiency of the body fluid on the tissue before the body fluid is drawn into the capillary channel; the capillary channel having an opening for receiving the body fluid; and the test strip having the fluid detector disposed at the opening to sense distance between the opening and the tissue. - View Dependent Claims (13, 14)

15. A body fluid sampling device, comprising:
-
a test strip comprising a capillary channel with a capillary channel opening to draw body fluid from tissue, the capillary channel opening being located at an end of the test strip, an analysis portion located along the capillary channel to analyze the body fluid from the tissue, and one or more sensors disposed at the capillary channel opening at the end of the test strip configured to detect a position of the capillary channel opening relative to the tissue; a lancet coupled to the test strip to form an integrated lancing test strip; a mechanism coupled to the test strip configured to change the position of the capillary channel opening relative to the tissue; and a controller operatively coupled to the one or more sensors, the controller being configured to move the capillary channel opening with the mechanism to collect the body fluid from the tissue based on the position of the capillary channel opening detected by the one or more sensors. - View Dependent Claims (16, 17, 18, 19, 20)
