  • the present invention relates to a method, computer program, and system for providing a customized treatment guide using lymphedema diagnosis data. More specifically, a customized treatment that can apply pressure according to the lymphatic type of the subject's lymphedema using near-infrared images and visible light images. This relates to a method, computer program, and system for providing a customized treatment guide using lymphedema diagnosis data that provides guidance.
  • the lymphatic system consists of lymph vessels that carry lymph fluid along with a number of tissues and organs containing lymphoid tissue, a specialized form of reticular connective tissue containing large numbers of lymphocytes.
  • the thymic component of various lymphoid organs is composed of epithelial reticular tissue
  • the stroma and outer structure of lymphoid tissue are generally composed of a complex network of reticular fibers (desmoplastic cells) and reticular cells (anchoring macrophages). It moves interstitial fluid from the interstitium of tissues between tissues and blood vessels and plays important functions in maintaining homeostasis, metabolism, and immune function.
  • lymphatic vessels are known to play an important role in the pathophysiological mechanisms of malignant tumors, lymphedema, and inflammatory diseases.
  • Lymphatic vessels are similar in structure to blood vessels, but have thin walls and are joined to large lymph vessels (lymphatic vessels) with many plates and contain lymph capillaries that contain lymph nodes at various locations throughout the body. The areas with the highest concentration of lymph nodes are found in the face and neck, armpits, chest cavity, intestines and groin, and elbows and knees. In general, superficial lymphatic vessels of the epidermis extend along veins, while deep lymphatic vessels extend along arteries. Lymphatic vessels supply lymph throughout the body and return proteins to the cardiovascular system when they leak from the capillaries. Additionally, lymphatic vessels transport fat from the stomach into the blood. In cancer patients, lymphatic tissue has the function of monitoring and defending against foreign cells, bacteria, and cancer cells.
  • lymphocytes release substances that directly or indirectly destroy these invaders.
  • Other lymphocytes differentiate into plasma cells that secrete antibodies against foreign substances to help remove them.
  • Lymph nodes act as filters for foreign substances carried by lymph by their reticular fibrous tissue.
  • macrophages destroy foreign substances through phagocytosis.
  • lymph nodes produce lymphocytes, some of which are transported in the lymph to other parts of the body as part of the immune defense system.
  • the spleen, thymus, and tonsils are lymphoid organs that produce B-cells, T-cells, and lymphocytes, along with antibodies, respectively, to complete the immune defense line of the lymphatic system.
  • lymphatic vessels which play a role in draining tissue fluid from the interstitium of tissues, play an important role in immunological defense mechanisms, and the pathophysiological mechanisms of malignant tumors, lymphedema, and inflammatory diseases are known to play an important role in disorders of lymphatic vessel production.
  • lymphedema is a condition in which lymphatic fluid is stored under the skin due to lymphatic vessel blockage and abnormal protein accumulation occurs due to damage or blockage of lymphatic vessels. It is a degenerative product of apoptosis. This is the result of obstruction of lymphatic drainage from the lymphoid tissue area.
  • lymphatic vessels Infiltration of this obstructive tissue by macrophages leads to the elimination of lymphatic flow through proteolysis of the obstruction protein over a considerable period of time. In this way, when lymphatic vessels malfunction, problems arise in the movement of extracellular fluid and macromolecular substances, which ultimately leads to tissue edema, immune dysfunction, and fibrosis of interstitial tissue. Lymphedema occurs due to hereditary or secondary causes, and lymphedema caused by secondary causes often occurs after treatment of malignant tumors, including surgery and radiation therapy. Acquired edema is reported to occur in more than 45% of patients with breast cancer, the most common cancer in women, and in more than 10% of all cancer patients.
