Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments, and in particular relates to a portable arm circumference measuring device. Background Art

[0002] Upper limb lymphedema is a common complication after breast cancer surgery. This is because axillary lymph node dissection surgery removes the axillary lymph nodes, while also cutting and ligating the lymphatic vessels, thereby blocking the lymphatic return pathway and causing upper limb lymphatic reflux obstruction. A large amount of protein-containing lymph fluid is retained in the interstitial space, causing swelling of the relevant tissues. Over time, it can also cause thickening of the skin and subcutaneous tissue, edema, and fibrous tissue hyperplasia. At the same time, postoperative axillary effusion, infection, and scar contracture also hinder the lymphatic and venous return of the upper limbs. When measuring lymphedema, the circumference measurement method needs to be used. The measurement points are: base of the thumb, upper limb wrist crease, 10CM above the wrist crease, elbow fossa, 10cm above the elbow fossa, and the apex of the armpit.

[0003] For example, the utility model disclosed in the authorization announcement number CN214511156U is a PICC arm circumference measuring ruler, which includes an arm length ruler. The arm length ruler is divided into a fixed area at the rear and a measuring area at the front. The fixed area is an arc-shaped structure. The measuring area has a slide groove arranged along its length direction. The length of the slide groove is 10 cm. The end of the slide groove has a limiting groove, which is arranged along the length direction of the slide groove. At least one elastic limiting ball is provided on the limiting groove. A slider is slidably provided on the slide groove. A limiting block is fixed on the side wall of the slider. The limiting block has a countersunk hole used in conjunction with the elastic limiting ball. A detachable storage box is provided on the upper surface of the slider, and an arm circumference ruler is wound in the storage box. The arm length and arm circumference are measured at the same time to avoid errors in the measurement process and improve the measurement speed. When the above technical solution is used, it cannot quickly locate the patient's base of the thumb, upper limb wrist crease, 10CM above the wrist crease, elbow fossa, 10cm above the elbow fossa, and axillary vertex. It cannot quickly measure the circumference of the patient's base of the thumb, upper limb wrist crease, 10CM above the wrist crease, elbow fossa, 10cm above the elbow fossa, and axillary vertex, and the measurement efficiency is not high. At the same time, it cannot be adjusted according to the base of the thumb of the hand of different patients, and the measurement has limitations. For this reason, we propose a portable arm circumference measuring device. Utility Model Content
