Title: Heat exchanger and blood reservoir
Inventor: NOGAWA ATSUHIKO
IPC: A61M1/36
Filed: 1991-03-27
Abstract: PURPOSE:To prevent a residual air bubble from being generated by laying the straight section of each tube body obliquely with a horizontal plane, and forming a passage for an air bubble to be afloat near a position vertically above each oblique straight tube section. CONSTITUTION:A blood reservoir 1 has a housing 2 with internal blood storage space 5 for reserving blood, and a heat exchanger 9 for heating or cooling the blood. In addition, the heat exchanger 9 has a plurality of metal tube bodies 10 laid in parallel in the space 5 below and at the predetermined inclination angle with a horizontal plane H. Also, a vertical passage 36 allowing the floating of air bubbles is formed between the inner wall 34 of the housing 2 and the tube bodies 10 adjacent thereto near a position vertically above each tube body 10. Both ends of each tube body 10 are respectively communicated with the heating medium chamber 16 of an enclosure 14 and the heating medium chamber 17 of another enclosure 15. According to this construction, when the blood storage space 5 is primed, air bubbles contained in priming blood gather at an obliquely upward position along the slope of each tube body 10, become afloat through the passage 36 and are finally discharged.

Filed: 1996-04-10
Abstract: PROBLEM TO BE SOLVED: To detect precise temperature distribution for each picture element within a monitor range while clearly showing the monitor range by providing a detecting element, shield panel, scanning means, image processing means and discriminating means specified respectively. SOLUTION: This device has detecting elements 11-15, collimators 4 and 5, image processor 2 and discrimination processor 3.

The image processor 2 scans the detecting elements 11-15 in the direction of X-Y within the monitor range. Besides, the image processor 2 prepares the temperature distribution within the monitor range, based on detected outputs from the detecting elements 13-15. The discrimination processor 3 discriminates the flame from the temperature distribution. In this case, the detecting elements can be an array element, one-dimensionally arranging plural detecting elements as well.  As a result, since the interference of light can be prevented, the contour of the detection range of the detecting elements can be made clear, and the flame can be correctly discriminated.
