Description of the Related Art In a conventional sample transport system, various devices related to pretreatment, analysis, and posttreatment of a blood sample are connected by a sample transport line such as a belt conveyor, and since the number of such devices is large, the transport line is long. Tends to be.
On the other hand, the system is not completely automated. For example, when a parent sample is dispensed to make a child sample, supply, collection, and disposal of the parent sample, child sample container, pipette nozzle, etc. require human work. The operator has to move around in the system, but the long transport lines described above impede the movement and necessitate detouring movements. Incidentally, as a device related to this type, for example, Japanese Patent Application Laid-Open Nos. 2-64462 and 2-644.

を続行するが如く、オペレータ優先で制御される。Next, the operation of the present system, which is sequentially executed according to the program registered in the central processing unit, will be described. First, the operator installs the parent sample rack 2 in the sample loading unit 4, and consumables (online container, storage container, nozzle, offline container,
Install the stopper cap, label) on the specified part and execute the system startup operation. The parent sample blood collection tube is conveyed through the conveyance line 3, and is centrifuged, opened, online dispensed, offline dispensed, separated dispensed, and delivered to the collection unit 27. The on-line dispensed sub-container is conveyed through the transfer line 15 and is dispensed to the analyzer 22 to start the analysis, while the sub-container is unloaded to the collection unit 23. The storage container dispensed for storage is capped, attached with the same bar code label as the parent sample, arranged and stored in the storage cabinet 26, and then carried out to the collection unit 27 after it is no longer needed. As described above, the analysis of the sample and the pre-processing and post-processing are sequentially executed, but when the parent sample and consumables are exhausted, the collection unit is full, or the assist request buzzer sounds due to equipment failure, The operator needs to go straight to the work department for the recovery work. In that case, the operator acts by looking at the display unit 31, but the central processing unit monitors the rack passing state by the rack presence / absence detectors and internal counters before and after the crossing transportation lines 9a and 9b, and Stopper 34 when it can be opened
The indicator 31 is driven to the open side, and when the operator artificially opens and closes the line or passes the line, the detector 33 detects the open state, and at the same time, the rack stopper 32 is inserted to prevent passage of the rack and the line is closed. When the detector 33 detects the closed state by the operator, the rack stopper 32 is withdrawn and the rack transport is continued.

が不要となり、システムを安価に提供できる。In the present invention, the supply and removal of the on-line child container and the nozzle are done manually. However, by utilizing the linear arrangement of the transfer lines, the transfer can be carried up and down and reciprocated at both ends of the line. By providing a line, a return line for the rack at the bottom, a known automatic feeder in the supply section, and a disposal handling robot in the recovery section, further automation can be easily developed. Regarding the serum separation part, as in Japanese Patent Application No. 1-55806, a method in which a sub-container into which serum is separated and dispensed is transferred onto a parent sample blood collection tube, or serum that has been temporarily separated and retained is used. If a method is used in which a partition plug is placed in the middle of a blood collection tube and then dispensed, a labeling machine is not required, and the system can be provided at low cost.
