Biological measurement apparatus, biological observation apparatus and operation method for biological measurement apparatus
First Claim
1. A biological measurement apparatus for performing spectral measurement on a biological body, the biological measurement apparatus comprising:
- a tube portion having a distal-end opening portion and a proximal-end opening portion;
a liquid delivery apparatus that is connected with the proximal-end opening portion of the tube portion such that light from a light source that emits light in a predetermined wavelength band enters the proximal-end opening portion, and delivers a liquid from the proximal-end opening portion into the tube portion;
light separating means that is provided between the proximal-end opening portion and the light source, for separating light entering the proximal-end opening portion and return light which is returned through the liquid after reflection by the biological body as an object and emitted from the proximal-end opening portion, the return light resulting from reflection of the light which enters the proximal-end opening portion and is emitted from the distal-end opening portion after passing through the tube portion,a control section that performs a spectral measurement on the biological body based on an output of a photodetection section that detects the return light which is separated by the light separating means.

Abstract
A biological measurement apparatus includes: an endoscope including a treatment instrument insertion channel provided inside an insertion portion; a pump that delivers water into the treatment instrument insertion channel; an optical system, etc., that guide light from a light source that emits light in a predetermined wavelength band into the water delivered into the treatment instrument insertion channel; and a spectroscope that detects return light resulting from the light passing through the water, falling on and being reflected by an object and returning while passing through the water when the water is delivered from the pump.
