OPTICAL FIBER RETAINER, PHOTOTHERAPY DEVICE, AND PHOTOTHERAPY SYSTEM

Abstract

An optical fiber retainer is attached to a side surface of an optical fiber and maintains, within a channel of a medical tube, a fixed distance between the side surface of the optical fiber and an inner surface of the channel. The optical fiber retainer includes a substantially tubular main unit having a fiber hole through which the optical fiber extends. The main unit has a flow-path defining section that defines a flow path within the channel. The flow path allows a fluid to travel in a longitudinal direction of the main unit.
