AUTOMATIC ANALYSIS DEVICE

摘要

In an automatic analysis device, when an external force acts on a probe guard 26 in a horizontal direction, the probe guard 26 moves in a direction escaping from the external force around a center portion 47 of a test body container installing mechanism 1, and the probe guard 26 is separated from a fixed position. An outer circumferential wall 29 of the probe guard 26 invades a test body sampling mechanism track 28, and thus a risk that a sampling nozzle 23 of a test body sampling mechanism 5 invades the test body container installing mechanism 1 is avoided by the outer circumferential wall 29. When the probe guard 26 is separated from the fixed position, this is detected, and thus the operation of the test body sampling mechanism 5 and the test body container installing mechanism 1 is stopped.

主权项

1. An automatic analysis device, comprising:
a test body container arranging mechanism in which a test body container is arranged and the arranged test body container is moved; a test reagent container arranging mechanism in which a test reagent container is arranged; a reaction container arranging mechanism in which a reaction container for reacting a test body with a test reagent is arranged; a test body sampling mechanism which suctions the test body from the test body container arranged in the test body container arranging mechanism, and discharges the test body to the reaction container arranged in the reaction container arranging mechanism; a test reagent sampling mechanism which suctions the test reagent from the test reagent container arranged in the test reagent container arranging mechanism, and discharges the test reagent to the reaction container arranged in the reaction container arranging mechanism; an optical analyzer which analyzes the test body in the reaction container arranged in the reaction container arranging mechanism; a control unit which controls operations of the test body container arranging mechanism, the test reagent container arranging mechanism, the reaction container arranging mechanism, the test body sampling mechanism, and the test reagent sampling mechanism; and a probe guard which is arranged in the test body container arranging mechanism, and includes a guard wall surrounding the test body sampling mechanism when the test body sampling mechanism is positioned on the test body container arranging mechanism, and a retaining unit integrated with the guard wall and retained in an outer circumferential portion of the test body container arranging mechanism to be movable, wherein the test body container arranging mechanism includes a probe guard existence detecting sensor detecting a movement of the probe guard from a specific position, and the control unit stops a test body movement operation of the test body container arranging mechanism and a test body suction operation from the test body container of the test body sampling mechanism when the probe guard existence detecting sensor detects that the probe guard is moved from the specific position.
