Integrated spot monitoring device with fluid sensor
First Claim
1. An apparatus, comprising:
- an integrated lancing test strip device including a lancet configured to form an incision in tissue, a test strip coupled to the lancet for analyzing body fluid from the incision, and a retention mechanism that holds the lancet in a static position relative to the test strip before formation of the incision, wherein the retention mechanism is configured to release the lancet for retracting the lancet relative to the test strip in order to reduce interference by the lancet during collection of the body fluid with the test strip.

Abstract
An integrated lancing test strip device includes a lancet configured to form an incision in tissue and a test strip coupled to the lancet for analyzing body fluid. A retention mechanism acts as a detent to hold the lancet in a static position relative to the test strip before forming the incision. The retention mechanism is configured to release the lancet for retracting the lancet relative to the test strip to reduce smearing of body fluid by the lancet during collection of the fluid with the test strip. In one form, the retention mechanism includes breakable tabs that are broken to release the lancet, and the lancet is retracted via translational movement. The retention mechanism in another form includes one or more dimples that release the lancet when the lancet is retracted via rotational motion. In a further form, the entire integrated device is rotated to collect fluid.

13. A method, comprising:
-
holding a lancet in a fixed position relative to a test strip of an integrated lancing test strip device;
forming an incision in tissue with at least a portion of the lancet extending from the test strip;
releasing the lancet from the fixed position;
retracting the lancet after said forming the incision; and
collecting body fluid from the incision with the test strip after said retracting the lancet. - View Dependent Claims (14, 15, 16, 17)

18. An integrated lancing test strip device, comprising:
-
means for creating an incision in tissue;
means for analyzing body fluid from the incision; and
means for holding said means for creating the incision in relation to said means for analyzing the body fluid and for releasing said means for creating the incision upon application of force. - View Dependent Claims (19)

20. An apparatus, comprising:
-
an integrated lancing test strip device including a test strip for analyzing body fluid, the test strip having a capillary channel with an opening for drawing the body fluid via capillary action, wherein the test strip is flat, and a lancet directly coupled to the test strip for forming an incision in tissue; and
an actuation device coupled to the integrated lancing test strip device, the actuation device being configured to fire the lancet into the tissue, wherein the actuation device is configured to rotate the lancet away from the incision in order to minimize interference by the lancet as the body fluid from the incision is drawn into the capillary channel of the test strip. - View Dependent Claims (21, 22)
