Abstract
The invention relates to a fluid filtering device comprising a filter (2) for filtering a fluid and a substrate (3) comprising a collecting structure (4) for collecting the filtered fluid from the filter (2). An adhesive (5) holds the filter (2) in place with respect to the collecting structure (4). The filter (2), the substrate (3) with the collecting structure (4) and the adhesive (5) are arranged such that the collecting structure (4) contacts the filter (2) and the filter (2) is attached to the substrate (3) by the adhesive (5). The collecting structure is very close to the filter and the adhesive ensures that the collecting structure remains very close to the filter. The filtered fluid can therefore be collected very efficiently and very fast. The fluid filtering device is preferentially used for filtering blood in a biosensing device.
