[0001] The present application relates to the technical field of medical measuring instruments, in particular to a universal lymphedema measuring scale for upper and lower limbs. BACKGROUND
[0002] Lymphedema is a common and serious disease that seriously affects the quality of life of patients. Early lymphedema may subside on its own after adequate rest, but if it is not diagnosed and treated correctly in the early stage, it will delay the best treatment opportunity and cause a series of irreversible pathological changes, such as tissue fibrosis, limb dysfunction, etc., and even lifelong pain and physical disability. Therefore, early detection and early treatment are crucial to control the development of lymphedema. In the early detection and treatment of lymphedema, accurate measurement of the degree of edema of the affected limb is a key indicator for judging the condition and evaluating the treatment effect. However, there is a lack of simple and standardized four-limb lymphedema measuring tools on the market. The existing measurement methods mainly have the following problems: first, the measurement methods and standards used by different medical institutions or medical staff are inconsistent, resulting in a lack of comparability of the measurement results; second, the measurement is highly random, and when using ordinary soft rulers and other tools to measure, factors such as measurement position and measurement force are difficult to accurately control, which can easily introduce errors; third, the measurement operation is not standardized, and there is a lack of clear measurement process and standard, which greatly reduces the accuracy and reliability of the measurement results.
