Patent FR-2540250-A1 (FR)
IPC: G01N33/49
Filed: 1983-02-02
Abstract: An apparatus for blood analysis to determine the rate of corpuscle sedimentation. The apparatus has a first support (1) with several graduated tubes (4) open at both ends and held vertically in spaced relation on the first support. The tubes (4) have enlarged lower ends (4b) which can diverge. A second support (2) has blood sample containers (13) of larger diameter than the vertical tubes on the first support. The containers (13) are spaced apart on the said second support, the same distance as the tubes on the first support so the containers are respectively, vertically below the tubes. Sealing and flow inducing members engage in the diverging lower ends (4b) of the respective tubes. The support means (1, 2) are movable with respect to each other between a first position in which the tubes are vertically above the containers, and a second position in which the lower ends of the tubes are immersed in the containers. The sealing and flow inducing members are mounted on the first support for simultaneous movement between a lower position away from the tubes and an upper position engaging within the enlarged ends of the tubes. The movement of the sealing members into engagement with the interior of the tubes causes a predetermined quantity of blood to be forced upwardly into the smaller diameter graduated portions of each tube to permit determining the sedimentation rates of the different samples.
