FLUID STERILIZATION APPARATUS, DENTAL MEDICAL INSTRUMENT, AND FLUID STERILIZATION METHOD

摘要

PROBLEM TO BE SOLVED: To suppress a reduction in ultraviolet light irradiation efficiency.;SOLUTION: A fluid sterilization apparatus of an embodiment includes: a light source including a substrate on which an LED that emits ultraviolet light is mounted; a cylindrical flow passage member of which at least part is formed of a material with permeability to ultraviolet light, and which is irradiated with ultraviolet light emitted by the LED; and a reflective member which has a first reflective surface that is disposed to form a gap between the first reflective surface and each of the LED and the flow passage member, and which reflects ultraviolet light that has passed through the gap to the flow passage member.;SELECTED DRAWING: Figure 3;COPYRIGHT: (C)2017,JPO&INPIT
