11. A laser blood-flow meter comprising:
-
a laser-beam irradiator for irradiating laser beams to biological structure;
a detector for detecting scattered beams resulted from backward-scattering of said laser beams in said biological structure, said laser blood-flow meter measuring blood flow of said biological structure in accordance with said scattered beams detected by said detector;
a light-guide for guiding said scattered beams to said detector; and
a case in which said laser-beam irradiator, said light-guide and said detector are arranged, wherein said case has a flat contact-surface, as at least a part of an external surface thereof, at which said case makes contact with a surface of said biological structure when blood flow of said biological structure is measured, and said laser-beam irradiator, said light-guide and said detector are arranged in this order on a path substantially parallel with said flat contact-surface. - View Dependent Claims (12, 13, 14, 15)

21. A system for monitoring bio-data of biological structure, including a laser blood-flow meter measuring blood flow of said biological structure in accordance with scattered beams resulted from scattering of laser beams in said biological structure which laser beams have been irradiated to said biological structure, said system monitoring said bio-data, based on blood flow in a head of said bio-logical structure and blood flow in any one of quarters of said biological structure,
said system including a controller which judges whether a blood flow and a blood-flow waveform of a head of said biological structure are in synchronization with a blood flow and a blood-flow waveform of any one of quarters of said biological structure, and does not use a blood flow and a blood-flow waveform obtained when said blood flow and said blood-flow waveform of said head is not in synchronization with said blood flow and said blood-flow waveform of said any one of quarters, for monitoring said bio-data.
