Abstract

The invention relates to a near infrared lymphatic detector which belongs to the field of medical technology of lymphatic detection, and the detector solves the problem that an existing lymphatic detection device cannot position the lesion lymph node positions of a patient or determine the lesion lymph node forms. An image acquisition part is used for acquiring an fluorescence image of human tissue; the fluorescence image appears after a near infrared laser emission part radiates to the human tissue; the laser control signal input end of the near infrared laser emission part is connected with the laser control signal output end of an image acquisition controller; the sampling control signal output end of the image acquisition controller is connected with the sampling control signal input end of the image acquisition part; the image signal output end of the image acquisition part is connected with the image signal input end of the image acquisition controller; the image signal output end of the image acquisition controller is connected with the image signal input end of a computer; and the computer is used for processing an acquired image signal, and obtaining a lymphatic abnormality image. The near infrared lymphatic detector is applicable to near infrared lymphatic detection.

Description

technical field [0001] The invention relates to a near-infrared lymphatic detector, which belongs to the technical field of lymphatic detection medical technology. Background technique [0002] In the early stage of lymphoma, swollen lymph nodes can be felt on the body. Because it is not painful or itchy, it is often ignored by people, but this is actually an early symptom of lymphoma. About 60% of lymphatic cancers will have enlarged lymph nodes in the early stage of the neck, and the number will gradually increase from a single enlargement at the beginning, and the volume will also increase at the same time. [0003] Because lymphoid tumors can occur in lymphatic tissues throughout the body, such as the jaw, jaw, front neck, supraclavicular, underarm, groin, mediastinal cavity, or abdominal artery, sometimes in organs, subcutaneous nodules, tonsils, and mouth and nose , pharynx, stomach, small or large intestine, bone marrow, etc. Generally speaking, the early symptoms o...
