Title: BIOLOGICAL SAMPLE ANALYSIS DEVICE
Abstract:
The present invention makes it possible for the type of a biological sample to be recognized accurately even if a label affixing region of a biological sample tube is enlarged or the biological sample tube is reduced in size, making it difficult for the inside of the biological sample tube to be seen by eye. This biological sample analysis device is provided with: a camera 201a which captures an image of a blood collecting tube 209 containing a biological sample; an image processing unit 201b and a comparison analysis unit 206 which extract a region of existence of the biological sample by analyzing the image captured by the camera 201a; a light source 203a1, a light receiving unit 203a2, and a liquid surface position detecting unit 203b which detect a liquid surface position of the biological sample by detecting an amount of light transmitted through the blood collecting tube 209; and said comparison analysis unit 206 which determines the type of the biological sample contained in the blood collecting tube 209 by identifying a part to be used to determine the type of the biological sample, on the basis of the extracted region of existence of the biological sample and the detected liquid surface position of the biological sample, and acquiring color information of the identified part.
