Problems solved by technology
However, even though such blood collection and separation media provide good separation results for various blood components, the deposition of the whole blood sample must be done precisely and be e.g. perforated or eluted to recover the desired components in the whole blood sample may be difficult to identify
Furthermore, this blood collection and separation medium can be difficult to use in automated methods for collecting and separating blood components from whole blood samples

Abstract
The present invention relates to a blood component collection and separation medium (1) comprising a substrate (3) having a maximum flow pore diameter that enables at least red blood cells to be trapped on the surface of the substrate (3), the blood component collection and separation medium (1) comprising a boundary wall (7) forming a pattern (9) and made of a hydrophobic resin, the pattern (9) having: a collection zone (91); at least one storage area (93) intended to collect at least one component in the whole blood sample (5); and at least one channel (95) connecting the collection area (91) to the at least one storage area (93), the channel (95) forming a bottleneck between the collection area (91) and the storage area (93). The invention further relates to a blood component collection and separation device and a blood component separation and extraction method.
Description
technical field [0001] The present invention relates to the collection and separation of biological fluids. More particularly, the present invention relates to a blood component collection and separation medium, the use of the medium in a blood separation and extraction method, and a blood component collection and separation device implementing such a blood component collection and separation medium. More particularly, the present invention relates to devices for use as blood component collectors and separators. Background technique [0002] Biological samples are often used in laboratory and clinical settings to analyze various components in samples, such as blood samples. Biological samples are often processed in liquid form. Therefore, liquid samples are collected in collection equipment, processed, transported to the laboratory and stored. Movement around liquid samples (such as blood) presents various problems, including the risk of container breakage or leakage (whi...
