Automatic analysis apparatus

摘要

An automatic analysis apparatus that can suction a target sample through an sample dispensing probe at a single sample dispensing position by transferring a sample rack holder having one or more sample containers from a first sampler unit to a second sampler unit and by moving the transferred sample rack in a horizontal direction and up-and-down directions at the fixed single sample dispensing position. By fixing a fluid sampling position of a sample container held by a sample rack at the single position, a sample dispensing accuracy of an automatic analysis apparatus can be increased.

主权项

1. An automatic analysis apparatus comprising:
a first sampler unit configured to movably mount in parallel a plurality of regular first sample racks, each holding a plurality of sample containers, the first sampler unit including a waiting area for mounting a plurality of regular sample racks, an interruption area for mounting an urgent regular sample rack and a leaving area; a second sampler unit configured to mount at least one control sample rack in a preliminarily designated area and radially arrange the plurality of regular sample racks in areas other than the preliminarily designated area; a first moving device configured to transfer a target sample rack among the plurality of regular sample racks mounted on the waiting area or the interruption area of the first sampler unit onto the areas other than the preliminarily designated area of the second sampler unit and to eject the regular sample rack from the second sampler unit; a second moving device provided under the second sampler unit and configured to transfer each of the plurality of regular sample racks radially mounted on the second sampler unit to an extracting position of the second sampler unit; wherein the second moving device includes a third moving device configured to move the target sample rack placed at the extracting position of the second sampler unit in a horizontal rack moving direction to a fixed sample dispensing position and a fourth moving device configured to move the target sample rack moved by the third moving device in up-and-down directions at the fixed sample dispensing position; and a sample dispensing probe configured to suction each sample contained in each of the transferred sample containers mounted on the target sample rack at the fixed sample dispensing position.
