Examination of blood

Abstract

Abstract PURPOSE:To wash beads without generating a residual liquid in a reaction container and damaging the surfaces of the beads, by throwing a coarsely meshed basket body, in which beads coated with an antibody are allowed to fall, in the reaction container as it is. CONSTITUTION:Beads (a) coated with an antibody are allowed to fall in the cavity of a coarsely meshed basket body (d) formed into a cylindrical shape capable of being inserted in and detached from a reaction container (b) to be thrown in the reaction container (b) along with the basket body (d). The beads (a) reacted with the specimen and reagent injected in the reaction container (b) by a distribution device 2 before or after said beads (a) are thrown in the container (b). Subsequently, washing is performed by the injection of washing water in the reaction container (b) by a distribution nozzle 21 and the removal of washing water under suction by a suction nozzle 21. Thereafter, the beads (a) are lifted up from the reaction container (b) together with the basket body (d) to wash the interior of the reaction container (b) and again returned to the reaction container (b) or transferred to other reaction container (b) along with the basket body (d) drawn up to measure the concn. of an antigen.
