Patent ID: 7238534

Claim:
A device for withdrawing samples of liquid samples for analytical elements, wherein the device comprises: a carrier having a carrier surface defined by opposite carrier ends, a detection element having opposite first and second ends, and a cover having a surface defined by opposite first and second edges the surface facing the carrier and the second edge facing the first end of the detection element, the cover cooperating with the carrier surface and with the detection element to form a capillary-active channel, the channel having a sample application opening defined by at least one border positioned at one of the carrier ends, the channel extending at least from the opening to the second end of the detection element, such that the detection element is downstream of the opposite first and second edges of the cover and wherein at least one notch in the form of a partial groove and having a width less than that of the channel is positioned at the at least one border of the sample application opening of the channel so that one side of the border of the sample application opening is at least partially interrupted by the at least one notch and the surface facing the channel opposite to the at least one notch is exposed.
