SPRAYING DEVICE FOR ENDOSCOPE

摘要

PROBLEM TO BE SOLVED: To provide a spraying device for an endoscope by which a sufficiently wide range of spraying can be obtained. SOLUTION: The inner wall surface 21 of a tip side in a liquid whirling chamber 20 is formed so as to be protruded to a jetting hole 17 side and to be a shape in which the direction of the surface changes on the way so that the part nearer the center than the peripherals may approach vertical to an axis.
