BODY FLUID SAMPLING DEVICE
First Claim
1. An analytical device, comprising:
- a support structure having a channel therein which is accessible from the surrounding in at least an access region, said channel having a fluid introduction region as well as a discharge region located downstream the access region; and
a fluid receiving means, the fluid receiving means being spaced from the channel in a first state and the fluid receiving means being in contact with fluid located in the access region in a second state to receive fluid, so that the fluid receiving means is not contacted with a fluid from the discharge region.

Abstract
Body fluid sampling device comprising a skin-piercing element having a fluid pathway for receiving body fluid, at least a portion of said fluid pathway is open to the environment and further comprising a fluid receiving means being spaced from said fluid pathway so that fluid in said pathway will not contact the fluid receiving means initially. Said fluid receiving means may have a test zone for performing an analytical reaction. Fluid from said channel is contacted with said fluid receiving means either by bringing the fluid receiving means and the fluid into mechanical contact or by electrically transporting fluid from the channel onto the fluid receiving means.

2. An analytical device, comprising:
-
a support structure having a channel for receiving fluid therein which is accessible from the surrounding in at least an access region; a fluid receiving means being spaced from the channel; and a source of electrical potential which when turned on applies an electrical potential between fluid in said access region and said fluid receiving means so that fluid from said access region is transported onto said fluid receiving means. - View Dependent Claims (3, 4)

5. A method for transporting fluid from a support structure to a fluid receiving means, comprising the steps of:
-
holding a support structure having a channel for receiving fluid therein which is accessible from the surrounding in at least an access region in a spaced relationship to a fluid receiving means; and applying an electrical potential between fluid in said access region and said fluid receiving means so that fluid from said access region is transported onto said fluid receiving means.
