As shown in Fig. 1, a predetermined amount of blood as a specimen is titrated into a large number of test tubes a supported in parallel on a rack 3 (or into test holes arranged in a large number on a titration plate), and a predetermined amount of blood is titrated in advance. React with the reagent on the surface of reaction sphere b (beads coated with a reagent that reacts with blood) placed in tube a (the reagent is coated on the inner wall of the test tube or the inner wall of the test hole). ), then reaction sphere b in test tube a
This is done by washing the test tube a with a cleaning solution and inspecting the surface of the washed reaction bulb b.
The cleaning of the reaction bulb b (or the inner surface of the test tube/test hole) in the (or test hole) is usually carried out using a rack 3 (or a titration plate with a large number of aligned test holes) that supports the test tubes a in parallel. ) is set on the base plate 4 provided in the machine frame K of the washing device M, as shown in FIG. A large number of dispensing needles 1 and suction needles 2 are arranged vertically in a set, and the washing liquid is fed to the head A from this state to each dispensing needle 1.
A fixed amount of washing liquid is injected into each test tube a from ..., and then the base plate 4 is raised by the lifting device 40 (the head A may be lowered) and the suction needle 2 is injected into each test tube a. In this state, the washing liquid is suctioned and removed by each suction needle 2 by the operation of the vacuum pump connected to the head A, and then the base plate 4 is lowered to insert the suction needles 2 into the test tube a. Pull it upward from the needle, and in that state, pipet the washing liquid again into the dispensing needle 1...
This is done by dispensing and repeating this process.
