Provided is a specimen-processing device configured so that a flow operation can be performed by deforming an elastic membrane. The present invention has an analysis chip that is a processing unit having a first flow path through which a liquid flows on a lower-surface side, a drive unit that controls air, a membrane that is an elastic membrane disposed between the processing unit and the drive unit, and an air pressure control unit that switches the elastic membrane between adhering to the processing-unit side and adhering to the drive-unit side. The processing unit has formed therein a circulation groove that is a second flow path through which air flows, the circulation groove being formed on the opposite side from the side where the drive unit is disposed, and an adhesion film that is a hermetic sealing film, the adhesion film being provided above the second flow path of the processing unit. The processing unit has a plurality of wells that are containers for storing the air and the liquid, each of the wells being connected to the second flow path. The air in the containers flows through the second flow path. This specimen-processing device makes it possible to enable a flow operation in a hermetically sealed processing unit.

An olfaction test device (1) causes air flowing into an inflow path (120) by use of a compressor (121) to have a constant flow velocity and a constant flow rate by passing the air through a sonic nozzle (124). The air is caused to pass through an opened one of inflow valves (126 to 129) disposed in branches of the inflow path (120) and to flow into any one of sample containers (101 to 104), whereby gases with different smell intensities are generated. The gases are then warmed by a heater (153) disposed in an outflow path (150) and released in a nose mask (155).

This sample processing device comprises: an analysis chip having a flow path on a lower surface side; a drive unit having a plurality of recesses on an upper surface side; an elastic film positioned between the analysis chip and the drive unit; and an air pressure control unit that switches whether the elastic film is adhered to the analysis chip side or adhered to the drive unit side. The analysis chip includes a quantitative flow path for quantifying liquid, and at least four branch flow paths branched from the quantitative flow path. The drive unit includes recesses below each of the ends of the four branch flow paths not on the quantitative flow path side, and each of the recesses communicates with the air pressure control unit.

Disclosed is a specimen measurement apparatus comprising: a measurement unit configured to suction a specimen from a specimen container and measure the suctioned specimen; and a specimen transport unit configured to transport the specimen container to the measurement unit, wherein the specimen transport unit includes a first transport part including a first placement surface configured to allow a specimen rack to be placed thereon, the first transport part being configured to transport a plurality of the specimen racks, each holding the specimen container, on the first placement surface, and a second transport part disposed above the first transport part and including a second placement surface configured to allow the specimen rack to be placed thereon, the second transport part being configured to transport a plurality of the specimen racks on the second placement surface, and at least one of the first transport part and the second transport part is configured to allow the specimen rack to be taken out therefrom or set thereon by a user in a state where the first placement surface and the second placement surface are located at predetermined positions for transporting the specimen rack.

An automatic food inspection device includes a feeding container, a track conveying device, an analysis control module and a screening module. The feeding container is used for accommodating the objects to be tested, the track conveying device is connected to the feeding container, and the track conveying device includes a conveying track and a vibrator. The conveying track includes a first end and a second end. The vibrator is connected to the first end of the conveying track to drive the objects to be tested to move forward to the second end. The analysis control module is configured to judge the qualities of the objects to be tested, and the screening module classifies the objects to be tested according to the judgment results of the analysis control module.

A test fixture includes a cylindrical main body extending in a longitudinal direction that receives a test piece. The main body includes a cylindrical screen filter with a mesh surface that extends in along a longitudinal axis coincident with an axis of the main body. The mesh surface generates a filter cake when particle-entrained fluid is supplied through the mesh surface and the particulate is retained on the mesh surface. The main body also includes an offset shaft that extends in the longitudinal direction along an offset axis that is offset from the axis of the main body, and the test piece extends through the offset shaft and the interior of the screen filter. The main body further includes a bearing that decouples rotational motion of the offset shaft from the end cap. Additionally, the test fixture includes an actuator that dislodges the test piece from the filter cake, a computer that determines the dislodging force, and a reservoir pump that pumps the particle-entrained fluid into the screen filter. When the alignment wheel is actuated, the offset shaft forces the test piece to move from a first position where a longitudinal axis of the test piece is coincident to the longitudinal axis of the screen filter to a second position in which the axes are offset.
