fiberscope

Abstract

Abstract PURPOSE:To make a liquid passage as large as possible and to obtain a large flush flow rate by using the gap formed of the internal wall of a coated tube and external surfaces of an image fiber and light guides as the guide passage for transparent liquid. CONSTITUTION:The fiber bundle 10 consisting of the image fiber 11 and light guides 9 is inserted loosely into the flexible coated tube 1 of a fiberscope inserted into a blood vessel, etc., and the gap is formed of the tube internal wall and the external surface of this fiber bundle 10 is formed and used as the liquid guide passage 15' for a physiological salt solution. Consequently, the effective cross section area of the liquid guide passage 15' is increased to obtain a flush flow rate enough to form a transparent area by excluding blood temporarily.
