摘要： An extravasation detecting apparatus is provided which is capable of detecting at an early stage the dislodgment of a tip opening of a solution supplying tool from a blood vessel. The extravasation detecting apparatus includes: a fluid delivery unit which supplies a fluid medicine by repetitively performing operations of pressing and occluding a portion between a fluid medicine containing unit and a puncture site of an infusion tube, subsequently suctioning the fluid medicine from upstream using a restoring force of the infusion tube, and once again pressing and occluding the infusion tube to push out the fluid medicine toward downstream; a tube closing unit located upstream of the fluid delivery unit; and a blood detecting sensor which operates the tube closing unit during a solution supplying operation to generate negative pressure in a downstream infusion tube and which detects whether or not blood is being suctioned between the fluid delivery unit and the puncture site into the infusion tube from a punctured blood vessel.

摘要： A Josephson transmission line device comprising a Josephson transmission line consisting of a pair of superconducting layers and a junction layer disposed between the superconducting layers to constitute a Josephson junction; a fluxon stopping position constituted by at least one resistor element in at least a part of the Josephson transmission line; a fluxon driving current source connected to the resistor element; a fluxon generating current source connected to the Josephson transmission line for generating fluxons therein; and an output circuit for extracting the fluxons generated in the Josephson transmission line as output signals. Fluxons generated in the Josephson transmission line can be made to stop at and depart from the stopping positions by selective application of fluxon driving current. Therefore, the Josephson transmission line can, alone or in combination with other such lines, be made to operate as compact, high-speed, low power-dissipation Josephson electronic circuit devices capable of functioning as logic circuits, memories, pulse generators, etc.
