Abstract

When processing a specimen by a plurality of specimen processing devices arranged along a transportation line, a specimen tag on which a coded group code representing a combination including at least one processing item is adhered on the specimen container. A plurality of such specimen containers are mounted on a specimen support bearing a specific carrier tag. Prior to transporting the specimen support, the specimen tags and the carrier tag are read, and based on the read result, an information management and controlling unit and the respective specimen processing devices manage a corresponding relationship between the carrier tag and the group codes. At the respective specimen processing devices the specimen support is identified and the processing corresponding to the group code is performed for the respective concerned specimen.

Claims

1. A specimen processing system comprising a specimen carrier carrying specimen containers each being capable of containing specimen, a transportation line for transportating the specimen carrier and a plurality of specimen processing devices arranged along the transportation line, further comprising

specimen tags each attached on the outer wall of the respective specimen containers and including a code representing specimen number and a group code representing one of grouped combinations of processing items performed by at least one of the plurality of specimen processing devices for the specimen contained in the concerned specimen container;

identifiably coded carrier tags each formed on the specimen carrier;

a specimen tag reader for reading the specimen tags prior to transporting the specimen carrier toward the plurality of specimen processing devices;

a first carrier tag reader for reading the carrier tag prior to transporting the specimen carrier toward the plurality of specimen processing devices;

second carrier tag readers arranged for each of the plurality of specimen processing devices;

processing device controllers each forming a pair with each of the respective specimen processing devices and for receiving information read from the concerned second carrier tag reader; and

an information managing and controlling unit which registers corresponding relationship between the carrier tag and the group code for individual specimen carriers based on the read results of the specimen tags by the specimen tag reader and of the carrier tags by the first carrier tag reader, wherein each of the processing device controllers receives the registered corresponding relationship from the information managing and controlling unit and manages the carrier tag relating to the specimen processing device which forms a pair with the concerned processing device controller.

2. A specimen processing system according to claim 1, wherein each of the specimen processing devices, when carrier tag read by the concerned second carrier tag reader contains the group code corresponding to the processing items concerned to the specimen processing device, performs the processing of concerned processing items for the specimen container or the specimen on the specimen carrier bearing the read carrier tag.

3. A specimen processing system according to claim 1, wherein the processing items contained in the identifiable groups are selected from a group of centrifugal separation, plug opening, specimen pipetting, specimen analysis, plug closing and temporarily standing-by.

4. A specimen processing system according to claim 1, wherein when a processing item is included which does not correspond to any of preset groups among specimen tags read by the specimen tag reader, the information managing and controlling unit sets an inquiry request command to a specific processing device controller of a concerned specific specimen processing device which is determined to perform the processing of the non corresponding processing items, and when the specific processing device controller recognizes the concerned carrier tag having the corresponding relationship with the non corresponding processing items, the specific processing device controller inquires processing information to the information managing and controlling unit and controls based on the processing information received from the information managing and controlling unit the concerned specific specimen processing device so as to perform the non corresponding processing items.

5. A specimen processing system according to claim 1, wherein the specimen processing system is further provided with a specimen distributing device in which, after reading tags with the specimen tag reader and the first carrier tag reader, a plurality of specimen containers bearing a same group code are mounted on a common specimen carrier and a specimen carrier completing the mounting of the plurality of specimen containers is supplied to the transportation line.
