STIRRER IN AUTOMATIC BIOCHEMICAL ANALYZER

摘要

PROBLEM TO BE SOLVED: To detect many different samples in a predetermined time by setting the time of stirring work as short as possible thereby shortening the time required for detecting reaction of sample. SOLUTION: When a reaction case 11 containing a sample to be stirred arrives at a stirring position, a stirring rod 40 enters into the reaction case 11. Subsequently, a cam disc 32 is turned through driving of a motor for back/ forth motion and the rotation of the cam disc 32 is converted through a rotation/straight advance conversion cam mechanism 32, 33, 36a into a straight reciprocal motion of a second motor supporting bracket 36. Consequently, the stirring rod 40 reciprocates in the reaction case 11. At the same time, the stirring rod 40 performs rotational motion in the reaction case 11 through driving of a motor 37 for rotational motion. Since the stirring rod 40 performs straight reciprocal motion and rotational motion simultaneously in the reaction case 11, sample and reagant are stirred efficiently. Consequently, sample and reagent are stirred quickly and uniformly and the stirring time is shortened significantly.
