Filed: 1988-12-19
Abstract: PURPOSE:To make it unnecessary to separately provide a light source for illumination by arranging a light source part and a light receiving part side by side at one tip of a light guiding path separated into two in the same plane as that of a substrate. CONSTITUTION:A light beam emitted from a light emitting part 15a provided for one tip of a light guiding path 14 is guided from an incident light path 14a through a common light path 14c to an opposite side reading part 14d in the light guiding path 14, and the surface of an original 17 is irradiated with the light beam. Further, a reflected light beam corresponding to the various densities of the original 17 is passed from the common light path 14c through a reflected light path 14b again and detected by a light receiving part 15b, photoelectric conversion is executed according to the detection, and the information of the original 17 is read. Thus, the light source for illumination becomes unnecessary by integrally fitting the light source part 15a and the light receiving part 15b to the light guiding path 14.

IPC: A61M1/18
Filed: 1987-12-18
Abstract: PURPOSE:To prevent channeling of blood with the blood flowing uniforming from the outside to the central side of the hollow thread bundle by inserting a cylinder shaped mesh into a bundle of hollow thread in parallel with the hollow thread. CONSTITUTION:In the space between the outer cylinder 2 and the inner cylinder 3 a number of porous hollow thread 4 is installed in bundles, within which a mesh 5 is installed. Blood A enters into the artificial lung through a blood inlet 1 and then flows into the hollow thread bundle consisting of the porous hollow thread 4 installed outside of the mesh 5 to run against the mesh 5, with decrease in blood flow rate. On the other hand, blood flows into the hollow thread 4 which is inside the mesh 5 from the similar level to the blood inlet 1, and is distributed evenly over the whole area of the artificial lung, with prevention of channeling. By opening outlet of blood in several sites in the lower part of the inner cylinder 3 to the direction of circumference, blood A is brought in contact with oxygen gas sent from the oxygen gas inlet 7 to the hollow portion of the porous thread 4 by way of the fine pores made in the porous hollow thread 4 to exchange gas, and then derived into the inner cylinder 3 from the outlet to be retained there. In this way, in blood A a favorable exchanged of gas with oxygen gas may be effected.
