Abstract: An inspection result of a specimen inspection automation system can be reported within a prescribed time, even if a large number of urgent specimens have been input. An instruction reception unit receives turn around time (TAT) information and a discharge instruction. The necessity of discharging a specimen for which the instruction was issued with the discharge instruction is determined and a discharge instruction unit creates a discharge destination and a conveyance route to the discharge destination for the specimen. A discharge mechanism discharges the specimen for which the instruction was issued. Even for a specimen which is caused to wait for processing due to the occurrence of specimen congestion and for which there is a risk of an inspection result reporting delay, an inspection result can be reported within a prescribed time by switching from automatic processing by the system to manual processing by an operator.

Abstract: A time period that is required for dealing with the need to access another place in advance of a device which is generating an alarm is reduced. Information of a task being presently executed by a laboratory technician present in a clinical laboratory is acquired from a responsible person schedule management table. Information based on a distance between the present position of the laboratory technician present in the clinical laboratory and a positional information reference point that indicates the position first accessed by the laboratory technician to deal with the alarm and that is specified from an alarm information management table and an alarm handling access position management table is also acquired. Based on the acquired information, ordering for issuing a notification of the alarm of which generation has been detected is performed for the laboratory technician present in the clinical inspection room.

Abstract: In a two-dimensional conveyance line employing an electromagnetic conveyance technique, carriers are conveyed in consideration of the length of a group of stagnated carriers, so as to reduce idle positions and ensure conveyance efficiency of a specimen inspection system and maximize the number of carriers conveyed simultaneously. Current is supplied to a winding of an electromagnetic circuit and an electromagnetic force is generated between the winding and a carrier with a magnet that holds a test tube to move the carrier. The processing efficiency of a specimen inspection system is improved by changing the current of the electromagnetic circuit to change a conveyance speed of the carrier to which the specimen sample is mounted, and by shortening the conveyance time, and reducing the conveyance speed of the carrier and increasing the number of carriers that are conveyed simultaneously as an alternative to detouring the carrier during congestion.
