Plasma or serum separator

摘要

A plasma or serum separator (10) for isolating plasma or serum from whole blood, comprises: a blood separation member (12), configured for separating blood applied to a first portion such that the plasma or serum of the blood is located in a second portion; a holding member (14) covering and holding the blood separation member (12); a blood introducing portion (16) formed in a portion of the holding member (14) covering the first portion; a plasma or serum sampling aperture (18) formed in a portion of the holding member (14) covering the second portion; and at least one plasma or serum collecting cavity (22) arranged at the second portion in fluid communication with the plasma or serum sampling aperture (18) for collecting plasma or serum leaving the blood separation member (12) through the plasma or serum sampling aperture (18).

1. A plasma or serum separator (10) for isolating plasma or serum from whole blood, the plasma or serum separator (10) being formed as a strip and comprising:
a blood separation member (12), configured for separating blood applied to a first portion of the blood separation member (12) such that the plasma or serum of the blood is located in a second portion of the blood separation member (12); a holding member (14) covering and holding the blood separation member (12), wherein the holding member (14) includes a base film (14a) on its lower side and a covering film (14b) on its upper side with the blood separation member (12) being sandwiched between the base film (14a) and the covering film (14b); a blood introducing portion (16) formed in a portion of the holding member (14) covering the first portion of the blood separation member (12); a plasma or serum sampling aperture (18) formed in a portion of the holding member (14) covering the second portion of the blood separation member (12), characterized in that the separator (10) is configured for plasma or serum to be extracted from the blood separation member (12) through the plasma or serum sampling aperture (18) by applying pressure to the blood separation member (12) in order to squeeze out the plasma or serum and further comprises at least one plasma or serum collecting cavity (22) formed within the strip, the at least one plasma or serum collecting cavity (22) being defined by the base film (14a) at its bottom and the covering film (14b) at its sides and arranged at the second portion of the blood separation member (12) in fluid communication with the plasma or serum sampling aperture (18) for collecting plasma or serum leaving the blood separation member (12) through the plasma or serum sampling aperture (18).
