Abstract: PROBLEM TO BE SOLVED: To avoid a system error even when shortage of reagents is generated in a system connected to a conveying line for a plurality of analyzers. SOLUTION: A conveyance control part 30 has a remaining amount computing part 32. A remaining amount of each reagent in each analyzer is computed theoretically by the computing part 32. A fed objective determining part 38 determines a fed objective analyzer of each rack based on the computed remaining amount and the number of accumulated specimens. Alternatively, the remaining amounts are possibly measured by remaining amount detecting parts 40, 42, 44.

Abstract: PROBLEM TO BE SOLVED: To eliminate the need for the direct pasting of bar code labels on specimen containers and to make the recycling of bar code labels possible. SOLUTION: A label plate 12 is detachably mounted to the plate placing surface 10A of a rack main body 10. The placement is performed through the use of the magnetic force of a magnet 18. A label 26 is pasted to the label plate 12 at a location corresponding to each insertion hole 14. With the label plate 12 mounted, a protruded part 32 is engaged with the notch 30. Even with the protruded part 32 engaged with the notch 30, it is possible to shift the label plate 12 upward. This facilitates the removal of the label plate 12.

Abstract: PROBLEM TO BE SOLVED: To simply discard a part where contamination is generated at the time of the collection of a blood specimen and to simply and rapidly collect the blood specimen. SOLUTION: A blood specimen collecting coupler 10 is constituted of a coupling part 16 equipped with a collection needle 20 and a vol. variable part 18. The collection needle 20 is thrust through the sealing cock 34 of a blood collecting tube 12 and a collection container 14 is mounted on a seal part 30. If the vol. variable part 18 is elastically deformed to increase and decrease the pressure in the collection container 14, the blood specimen in the blood collecting tube 12 can be taken in the collection container 14 through the collection needle 12. If a valve structure is provided in the vol. variable part 18, the outflow air from the interior of the coupling part is permitted and the inflow of air from the outside can be prevented and, by this constitution, pressure can be increased and decreased under atmospheric pressure or less.

Abstract: PROBLEM TO BE SOLVED: To reduce the operation wait time of a carrying mechanism and label-affixing device as much as possible just by the addition of a simple structure and maximize ability to process. SOLUTION: A buffer hole 28 is made near an insertion hole 26, and a container is transferred from the insertion hole 26 to the buffer hole 28 by means of a subhandler 30. In a storing section 20, a label-affixing device 36 is provided and a label is affixed to the container. The labelled container is once stored in the buffer hole 28 by the subhandler 30. Right after that, the following container is inserted into the insertion hole 26 by a main handler, and then the main handler returns and carries the labelled container existing in the buffer hole 28. The label-affixing device may be provided below the storing section 20, in which case the insertion hole 26 and buffer hole 28 are through-holes.

Abstract: PROBLEM TO BE SOLVED: To measure the color of a sample optically while performing a series of dispensing operations by providing an at least partially transparent suction/ delivery nozzle, a section for optically measuring the color of a sample contained therein, and a nozzle carrying mechanism. SOLUTION: A nozzle tip 10 is made of a transparent resin, for example, and provided with a section 12 for measuring the color of a sample sucked therein. When the nozzle tip 10 is lowered from above a test tube 32 containing a sample by means of a nozzle carrying mechanism 24 and then elevated while sucking the sample, a predetermined measuring light emitted from an emitting section 36 is passed through the nozzle tip 10 and received at a light receiving section 38. It is then passed through an amplifier 42 and an A/D converter 44 to a data processing section 46 where various analyses are performed based on a determined color. Analytical results are presented on a display 48 and delivered, as required, to a biochemical analyzer. A dispensation control section 30 controls the carriage of a rack 34 holding test tubes 32 as well as a dispensation pump 28, the nozzle carrying mechanism 24 and the color measuring section 12.

Abstract: PURPOSE: To detect leak from piping system in automatic dispenser, especially from the joint between nozzle base and disposable chip. CONSTITUTION: Upon elapse of a predetermined time after sucking a liquid sample, the inner pressure of piping system is measured as an initial pressure level P1 by means of a pressure sensor. A chip is then elevated from the sucking position and when it is further transferred horizontally to a delivery position, the inner pressure of piping system is monitored. In first leak detection process, a leak detecting section determines the pressure difference ΔP2 between the inner pressure P2 of piping system during elevation of the chip and the initial pressure level P1 and makes a decision whether the piping system is leaked by comparing the pressure difference ΔP2 with a reference level A. In second leak detection process, the pressure difference ΔP3 between the inner pressure P3 of piping system and the initial pressure level P1 is determined during horizontal transfer of the chip and a decision is made whether the piping system is leaked by comparing the pressure difference ΔP3 with the reference level A. When leakage is detected, the liquid sample is delivered back and the chip is disposed.

Abstract: PURPOSE:To effectively prevent babbles from occurring by a method wherein right after a liquid level is detected, a dispensing pump is stopped to stop the ejection of an air and an air blow-off valve is opened. CONSTITUTION:A pump 18 is driven under control of a control section 22 so that a nozzle 10 is lowered by a drive section 24 by ejecting an air from a tip of the nozzle 10. When a pressure value detected by a pressure sensor 20 exceeds a threshold level, that is, a liquid level of a specimen 14 is detected, the pump 18 is immediately stopped and an air blow-off valve 26 is opened so that the lowering of the nozzle 10 is stopped. As a result, pressure in a pipeline (a pipe 16, a nozzle 10, a syringe) is suddenly reduced, thereby it is possible to effectively prevent bubbles from occurring and to enhance the dispensing accuracy.

Abstract: PURPOSE:To effectively remove an unreacted sample without having a bad influence on a reaction product formed at the inside of a well when the unreacted sample is sucked after a sample has been poured into the well in a microplate in which the inside of the well has been coated with a reagent. CONSTITUTION:Two suction nozzles 14 are arranged at the right and the left of a discharge nozzle 16, and the suction nozzles 14 are moved inside a well 12 to the front and the rear in a direction at right angles to their arrangement direction. When a sample is sucked during their horizontal movement, the sample which remains at corners is sucked and removed. Even after a cleaning liquid has been poured, it is sucked by the same movement.

Abstract: PURPOSE:To collect only serum from a centrifuged blood sample with a single collecting needle. CONSTITUTION:The collecting needle 59 of a collecting unit 18 is pierced through the sealing stopper of a blood collecting tube 12, and a rotating base 34 is rotated to lay the blood collecting tube 12 in the reversed state. The pressure in a cylinder 48 is repeatedly increased and reduced in this state, whereby the serum collected in the lower part of the blood collecting tube 12 is taken into the cylinder 48. The collecting unit 18 is used also as the pump of a dispensing device.

Abstract: PURPOSE:To make dilution quick when an erythrocyte component, which is high viscosity liquid, is diluted in a distributing apparatus of a blood sample. CONSTITUTION:In a step 212, diluent liquid is injected into a dilution container 66. In a step 213, the diluent liquid is sucked with a nozzle tip 36, which holds an erythrocyte component in the inside. Thus, the first stage of dilution is executed in the nozzle tip 36. In a step 214, the mixed liquid in the nozzle tip 36 is discharged. In steps 215 and 216, the discharging and the sucking are repeated. Thus, the dilution (mixing) is completed.
