Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of air tightness detection, and specifically relates to an air tightness test tool for an endoscope catheter insertion part. BACKGROUND

[0002] The air tightness test tool for an endoscope catheter insertion part is a device for detecting whether an endoscope catheter leaks, ensuring that it can maintain proper air tightness during use, preventing air or liquid from entering the catheter, and ensuring the safety and functionality of the endoscope.

[0003] The existing catheter air tightness test tool is mostly used to detect the air tightness of the pipe body by introducing high-pressure gas into the sealed pipe body. This detection method usually requires the inner wall of the pipe body to be airtight. However, the existing manual or instrument-assisted catheter fixing structure is often not only airtight but also very cumbersome to operate when used for detecting the endoscope catheter insertion part. In actual use, the endoscope catheter insertion part is prone to falling off from the origin interface, thereby affecting the detection efficiency.

[0004] Therefore, in view of the above-mentioned problems of the existing air tightness test tool for an endoscope catheter insertion part, which is cumbersome to operate and prone to falling off during detection, an air tightness test tool for an endoscope catheter insertion part is developed. By adding a buckle type limiting connection structure and a positioning support structure to the air tightness test tool for an endoscope catheter insertion part, the convenience of the air tightness test tool can be greatly improved, and the stability of the endoscope catheter insertion part during air tightness detection can be improved.
