Description
Technical Field
[0001] The utility model relates to the technical field of upper arm circumference measurement of lymphedema, in particular to a multifunctional measuring ruler. Background Art
[0002] Lymphedema refers to tissue swelling caused by a buildup of protein-rich fluids that are normally drained away through the body's lymphatic system. Lymphedema most commonly affects the arms or legs, but may also occur in the chest wall, abdomen, neck, and other locations. Lymph nodes are an important part of the lymphatic system. Lymphedema may result from removal or damage to lymph nodes during cancer treatment. Limb lymphedema is a common complication. Arm circumference measurement is often used to diagnose upper limb lymphedema after surgery.
[0003] Most of the existing measurement methods require the operator to use an inelastic tape measure to mark a line from the wrist to the armpit with a colored pen, and then measure the arm circumference at the marked point. This measurement method is simple and can be used in any occasion with only one tape measure. Patients can measure at home, but the position of the measuring tape is not easy to fix during the measurement process, resulting in poor measurement accuracy and inconvenience for patients to operate with one hand. Especially for obese patients, the tightness of the tape measure will cause measurement errors, which will seriously affect the measurement results.
[0004] Therefore, the utility model provides a multifunctional measuring ruler to solve the problems raised in the above background technology. Utility Model Content
