Patent ID: 11085913

Abstract:
A biological sample analyzer includes: a camera 201a imaging a blood collection tube 209 containing a biological sample; an image processing section 201b and a comparative analysis section 206 that analyze the image imaged by the camera in order to extract an existence region of the biological sample; a light source 203a1, a photo sensor 203a2 and a liquid-level position detection section 203b that detect the amount of transmitted light in the blood collection tube 209 in order to detect a liquid-level position of the biological sample; and the comparative analysis section 206 that, based on the extracted existence region of the biological sample and the detected liquid-level position of the biological sample, identifies a determination target portion for a category of the biological sample, and acquires color information on the identified portion, in order to determine a category of the biological sample contained in the blood collection tube 209.
