ABSTRACT:
A sampling device of the suction effusion fluid that is good in sampling operation efficiency. This device includes a cell with a vacuum suction port and a skin suction port, a slide valve formed in the cell, and fluid reservoirs formed in the valve. The slide valve is movable in a plane approximately parallel to the skin surface. The slide valve opens or closes a communication path communicating the skin suction port with the vacuum suction port. Each of the fluid reservoirs is alternately communicated with the skin suction port and the vacuum suction port through the communication path by sliding movement of the slide valve. Each of the fluid reservoirs stores an effusion fluid acquired from the skin surface by vacuum suction through the skin suction port. When the slide valve is located at a position where one of the fluid reservoirs is communicated with the skin suction port and the vacuum suction port, at least one of the remaining fluid reservoirs is exposed to the outside of the cell. The slide valve preferably has a rod or disk shape.
