PURPOSE:To make it possible to prepare a blood specimen, whose blood image is readily recognized, automatically, by preparing the blood into known concentration diluents for red corpuscles and white corpuscles, and applying the respective diluents on the respective applying regions of the same transparent substrate. CONSTITUTION:A part of the entire collected blood is diluted by about 500 times. The red corpuscles are dissoved by hemolysis agent, and the diluent suspension of the white corpuscles is adjusted. By using an aperture tube and a constant quantity sucking and injecting device, the concentration of the white corpuscles is computed by an operation control device 11. A part of the entire blood is diluted by about 2,500 times, and the concentration of red corpuscles with the red corpuscle diluent suspension is likewise obtained. The red corpuscle diluent is sent to a specimen container 20 from the constant quantity sucking and injecting device 8. Red corpuscle spots B1-Bn are formed on a glass plate 19 on a movable stage 16, by a nozzle 21A of a dropping container 21, which is provided with an ultrasonic wave vibrator 18. Then, the containrs 20 and 21 and the like are washed. Thereafter the white corpuscle diluent is sent from the constant quantity sucking and injecting device 7 and white corpuscle spots C1-Cn are formed by the similar way. It is recommended that dense corpuscle spots A1-An for visual observation are separately provided. Thus the speciman, which can be readily recognized, can be automatically obtained by the operation control device 11 without dyeing classification. |
