[0002] Medical catheters are essential components of medical devices, and their concentricity directly impacts their performance and safety. While the production process for medical catheters is relatively mature, variations in concentricity can occur during the manufacturing process due to factors such as materials, molds, and process. Catheters with substandard concentricity can lead to poor fluid flow, increased patient discomfort, and even medical accidents. Therefore, accurate concentricity testing of medical catheters is crucial for ensuring product quality.
