BIOLOGICAL OPTICAL MEASUREMENT INSTRUMENT AND METHOD FOR DISPLAYING INFORMATION RELATING TO NECESSITY/UNNECESSITY OF REPLACEMENT OF LIGHT-EMITTING UNIT
First Claim
1. A biological optical measurement instrument comprising:
- a light source unit which has light-emitting units that emit light, configured to irradiate the light to an object to be examined;
a light measurement unit configured to measure the transmitted light at a measurement point in the object;
a signal processing unit configured to process the hemoglobin information outputted from the light measurement unit and create a light measurement image; and
a display unit configured to display the light measurement image,further comprising a measurement/determination unit configured to measure the deterioration state of the light-emitting unit based on the light output of the light-emitting unit and the current injected into the light-emitting unit, and determines the necessity/unnecessity of replacement of the light-emitting unit,wherein the display unit displays the information on the necessity/unnecessity of replacing the light-emitting unit which is determined by the measurement/determination unit.

15. A method for displaying information regarding the necessity/unnecessity of replacement of a light-emitting unit including steps of:
-
measuring the deterioration state of a light-emitting unit from the light output of the light-emitting unit that emits light and the current injected into the light-emitting unit; determining the necessity/unnecessity of replacing the light-emitting unit from the deterioration state; and displaying the information regarding necessity/unnecessity of replacement of the light-emitting unit.
