Abstract: An organic EL element includes an organometallic complex including a rhenium atom; one ligand which has a coordinated nitrogen atom and a coordinated oxygen atom, each coordinated with the rhenium atom, and has at least one ? conjugation part; and the other ligand coordinated with the rhenium atom in such a way that the ligand saturates the coordination number of the rhenium atom and the charge of the whole organometallic complex is neutral.

Abstract: There is provided an apparatus which reduces a bleeding amount upon an operation. A bloodless treating apparatus used upon a surgical treatment of an objet comprises: (A) a fluid replacement supply unit which quantitatively supplies a fluid replacement into a blood vessel leading to the object (24); and (B) a fluid replacement withdrawing unit which quantitatively withdraws the fluid replacement having passed through the object (24) from a blood vessel coming from the object.

Abstract: An extracorporeal circulation apparatus used for the selective temperature controlling method in which a temperature of an object is kept at a predetermined temperature, includes: (A) a fluid replacement supply unit which quantitatively supplies a fluid replacement of which temperature has been adjusted into a blood vessel; (B) a blood concentration unit which quantitatively withdraws blood diluted by the fluid replacement from a blood vessel and concentrates the withdrawn diluted blood; and (C) a blood supply unit which controls a temperature of the blood which has been concentrated and quantitatively supplies the concentrated blood into a blood vessel, the blood concentration unit comprising a diluted blood temperature sensor which measures a temperature of the withdrawn diluted blood, and the fluid replacement supply unit including a means which controls a temperature of the fluid replacement to be supplied based on a different extent between the measured diluted blood temperature and the predetermined

Abstract: There is disclosed an apparatus for detecting an occlusion of a liquid transfusion tube in which a pump section is provided in a liquid transfusion tube for connecting an infusion liquid container with a body infusion element. An occlusion of the liquid transfusion tube is detected according to an amount of displacement of the liquid transfusion tube displaceable under a pressure of a liquid transfused to the liquid transfusion tube by an operation of the pump section.

Abstract: A transfusion apparatus including a pump section for sequentially pressing and blocking a transfusion tube to feed a liquid, a detecting section for detecting a given cycle of pump operation in the pump section, and a drive-control for driving and controlling the pump section is disclosed, in which the transfusion tube on an upstream side above the pump section is provided with a dropping cylinder on which is arranged a detector for counting the number of droplets and that the apparatus is further provided with a comparator for comparing the number of droplets in the given cycle of the pump operation with a predetermined value to judge a type of a transfusion set.

Abstract: A transfusion apparatus including a pump section for sequentially pressing and occluding a transfusion tube by means of a plurality of finger elements of a peristaltic type thereby to feed a liquid, a detecting section having (1) a circuit for detecting a given reference position of the pump section to generate a corresponding detection signal during periodic peristaltic movement of the pump section and (2) a circuit for detecting a working position of the pump section deviated from the reference position through the peristaltic movement thereby to generate a corresponding detection signal, and a drive controlling section for receiving the detected signals from the detecting section to compute and control the peristaltic rate thereby to maintain a constant delivery amount by the pump section.
