<P>PROBLEM TO BE SOLVED: To provide a medical infusion tube illuminating device, using a light source having high luminance and protecting an operator from danger even during operation in the dark with the pupils opened. <P>SOLUTION: This medical infusion tube illuminating device includes: an infusion tube holder 7 formed of a pair of holding pieces 5, 6 which hold an infusion tube 2, and confront each other orthogonal to the axis 3 of the infusion tube 2, and to which elastic force is applied in the mutual mating direction; a light emitting body 11 provided on one holding piece 6 and radiates light beams toward the other holding piece 5 with the normals of the opposite surfaces 5a, 6a of the confronting holding pieces 5, 6 as the optical axis 10 and with the normals substantially orthogonal to the axis 3 of the infusion tube 2; a spectral body 14 provided in front of the light emitting body 11 in the same holding piece 6 as the light emitting body 11 to make the central part 12 where the optical axis 10 of the light emitting body 11 straightness and make the outer peripheral part scattering; a polarizing surface 17 provided on the holding piece 5 in the light radiating direction of the light emitting body 11 to cause irregular reflection of the beams passed through the straightness part of the spectral body 14; and a power supply for lighting the light emitting body. <P>COPYRIGHT: (C)2008,JPO&INPIT |
