Description

Technical Field

[0001] The utility model belongs to the technical field of human limb edema volume measurement devices, and particularly relates to an edema volume measurement device. Background Art

[0002] During the treatment process in the breast department, lymphedema is a common disease after breast surgery. Lymphedema can cause obstruction of lymphatic return, resulting in pain and swelling of the affected upper limb, limb deformation, dysfunction, affecting joint movement, and can be secondary infected to further cause sclerosis and occlusion of the lymphatic lumen, endangering the health of patients. When lymphedema occurs, in order to facilitate the control and treatment of patients, it is usually necessary to measure the volume of the edematous limb of the patient.

[0003] Existing limb volume measurement devices mostly measure by the water displacement method. Usually, the limb is directly placed into a container filled with water and then the volume of the overflowing water is directly measured. In this measurement method, the patient's limb needs to be directly placed inside the water body. During the measurement process, the limb will come into large-area contact with the water body, easily making the patient's limb or clothing wet, making the patient feel uncomfortable. At the same time, the overflowing water is easy to scatter on the ground, causing the ground to be wet and affecting the measurement accuracy.

[0004] Moreover, most of the existing edema volume measurement devices in the prior art are for measuring a single upper limb or lower limb of a person, and cannot adjust the volume of the measurement device according to different parts. Therefore, improvement is needed. Summary of the Utility Model
