A transport carrier for a laboratory cargo distribution system with a transport plane is disclosed. The transport carrier can be rotationally moved in an easily controllable manner on the transport plane. A laboratory cargo distribution system with a transport plane comprising such a transport carrier and a laboratory automation system comprising such a laboratory cargo distribution system are also disclosed.

Disclosed is a specimen analyzer that uses a specimen rack in which a plurality of specimen containers can be held to analyze a specimen in each of the specimen containers, and the specimen analyzer includes: a measurement unit configured to measure the specimen; and a transport unit comprising a first placement region which is disposed in front of the measurement unit and in which a plurality of the specimen racks can be placed, and a second placement region which is disposed in a left-right direction relative to the first placement region and in which a plurality of the specimen racks can be placed, the transport unit configured to transport the specimen racks placed in the first placement region and the second placement region to a start position at which the measurement unit starts measurement.

A device and method for testing foodstuffs for the presence of microorganisms including an infeed unit for a package containing a foodstuff, a sample analysis device configured to take a sample of the foodstuff and test for the presence of microorganisms, a discharge unit for discharging the package, and a display for displaying the results of testing by the sample analysis device.

A main drive mechanism provided with a main motor drives a rack on a first main path and a rack on a second main path simultaneously in the forward direction or simultaneously in the reverse direction. The rack is sent along a first auxiliary path by a first auxiliary drive mechanism. Then the rack is further sent in the forward direction along the second main path by the main drive mechanism. Once the rack leaves the first receiving region, the first claw member of the first auxiliary drive mechanism is sent to a retraction position and the rack is driven by the main drive mechanism in the reverse direction. The first claw member is then sent to an engagement position on the first main transportation path, the main drive mechanism is driven for transport in the forward direction, and the rack and the first claw member engage each other.

In a conventional conveyor line, an empty specimen rack conveyor line is provided separately from a specimen rack conveyor line having a specimen mounted thereon. However, crossing of the conveyor lines leads to the decrease in processing speed. Also, when a specimen rack conveyor line and an empty specimen rack conveyor line are configured on two stages, a vertical movement mechanism needs to be added in order to connect the upper-stage conveyor line and the lower-stage conveyor line, and there is a possibility that the system is complicated and the cost thereof is increased. In the present invention, by connecting an empty holder conveyor line and a main conveyor line disposed up and down on two stages via one conveyor line having a horizontal part and an inclined part, crossing of the conveyor lines can be eliminated and an inexpensive structure can be achieved.

A sample analyzer includes: a reagent container holder including a reagent container holder body configured to hold a reagent container, and a tilt changing part configured to change a tilt of the reagent container holder body; a reagent dispenser configured to aspirate a reagent contained in the reagent container held in the reagent container holder body; a detector configured to detect a signal for analysis from a measurement specimen containing a sample and the reagent dispensed by the reagent dispenser; and a controller that analyzes the sample on the basis of the signal detected by the detector.

An extraction operation room is provided. The extraction operation room is provided with a multi-stage Z-direction extraction arm and an X-direction pushing system. Movement on a multi-distance road section in a Z-axis direction is realized by using the multi-stage Z-direction extraction arm, such that the movement of an extraction member on the multi-distance road section in the Z-axis direction is realized, thereby greatly increasing the depth or length of the movement in a Z axis. The corresponding X-direction pushing system is provided, and the X-direction pushing system realizes the movement of a tank cover of a sample storage tank or a storage box in an X-axis direction. An operation space is given when the movement in the Z-axis direction and the X-axis direction are implemented, and meanwhile, the extraction structure is reasonable in design, small in occupied space, relatively low in cost, and convenient and intelligent to operate.

A conveying track includes a frame, a delivery track is arranged on the frame, and is formed by assembling one or more kinds of H-shaped tracks, T-shaped tracks, L-shaped tracks, U-shaped tracks and I-shaped tracks, and a sample blocking device and/or a diversion device are/is arranged on the delivery track. The conveying track of the present invention has a more flexible track layout, and satisfies the diversified layout requirements of a laboratory delivery system, and thus the installation efficiency of the track is improved.
