[0002] PICC arm circumference measurement refers to the process of measuring the circumference at a specific location on the patient's upper arm (usually 10 cm above the elbow crease). The purpose of arm circumference measurement is to select the appropriate size, increase the success rate of intubation, and improve patient comfort. Measuring tools are required.

[0003] An existing arm circumference measuring tool for PICC patients (authorization announcement number: CN209916003U) has the following defects: the above tool effectively avoids the gap between the tape measure and the patient's arm, which leads to inaccurate data, thereby improving the accuracy of the measurement data. However, the above tool and some existing tools only rely on the tape measure to measure the circumference, and a 10 cm positioning measurement is required before the circumference measurement. To determine the position where the circumference measurement is required, a measuring ruler is usually used to mark the position after measurement.
