BODY FLUID SAMPLING DEVICE
First Claim
1. Body fluid sampling device comprising a skin-piercing element having a collection zone for receiving body fluid, wherein at least a portion of said collection zone is open to the environment and a fluid receiving means comprising a test zone and being spaced from said collection zone so that the fluid receiving means being out of fluidic contact with said collection zone, so that fluid present in said collection zone will not contact the fluid receiving means.

Abstract
Body fluid sampling device comprising a skin-piercing element having a collection zone for receiving body fluid, and the device further comprising a fluid receiving means remote spaced apart from the collection zone so that body fluid in the collection zone will not contact the fluid receiving means initially. The collection zone takes up a very small volume of body fluid of about 10 to 500 nl in a very short time period of less than 0.5 seconds. The fluid receiving means may have a test zone for performing an analytical reaction. Fluid sample from the collection zone is automatically or manually transported to the fluid receiving means to contact the fluid with the test zone.

28. Method for determining an analyte concentration in body fluid comprising the steps of:
-
a) receiving body fluid in a collection zone of a skin-piercing element, b) contacting the collection zone of the skin-piercing element with the fluid receiving means so that body fluid reaches a test zone on the fluid receiving means, c) receiving signals from said test zone which are characteristic for an analyte concentration d) processing said signals to determine the analyte concentration. - View Dependent Claims (29, 30, 31, 32, 33)
