摘要

PROBLEM TO BE SOLVED BY comprehension of proper suction of scattering matter and improvement of efficiency of work for enlarging visual recognition of a visual object.A dental extracorporeal aspiration hood 3 has a tubular portion 30 having a tubular shape and having a proximal end side X 1 attached thereto and a distal end side X 2 serving as a suction port and a tubular portion 30 having a distal side circumferential edge of the tubular portion 30 And a transparent partial tube wall portion 31 extending further to the distal end side X 2 than the portion 30 a. The partial tube wall portion 31 is provided with a lens portion 5 that enlarges a visual object when viewing the outer peripheral side Y 1 to the inner peripheral side Y 2.BACKGROUND OF THE INVENTION
