Description

Technical Field

[0001] The utility model relates to the technical field of hypotube size detection, in particular to a device for accurately measuring hypotube size. Background Art

[0002] A hypotube is a long metal tube with microengineered features throughout its entire length. It's a crucial component of minimally invasive catheters, used in conjunction with a balloon and stent to open blocked arteries. The balloon portion of the catheter is attached to the distal end of the hypotube. Once the hypotube enters the body, the balloon is pushed along the long, winding blood vessels toward the blocked artery. During this process, the hypotube must avoid kinking while navigating smoothly through the human anatomy.

[0003] Since the hypotube is a medical device, its dimensional error must be within a certain range before it can be used as a finished product. At this time, a device is needed to randomly inspect the products for dimensional testing. Utility Model Content
