AI Technical Summary

Technical Problem

The existing balloon dilation catheter testing process lacks fixation components, which prevents the catheter from being fully immersed in the water bath, resulting in inaccurate testing and safety hazards. Furthermore, it is prone to displacement during high-pressure injection, which is time-consuming and labor-intensive.

Method used

A test fixture for testing the bursting of a balloon dilation catheter was designed, including a water bath, a fixing component, and a protective device. The catheter is fixed in the water by the fixing component, and a heating plate and a temperature controller are installed in the water bath to control the temperature and prevent liquid splashing.

Benefits of technology

This method enables stable fixation of the catheter and accurate testing, improves testing efficiency, ensures testing safety and accuracy, and prevents liquid splashing.

Abstract

The utility model provides a blasting test tool for a balloon dilatation catheter. The blasting test tool comprises a water bath box, a box cover, a connecting joint, a first fixing piece and a second fixing piece, the connector is fixedly mounted in the middle of one end of the water bath; the first fixing piece comprises a first fixing plate and a first through hole formed in the middle of the first fixing plate. The second fixing piece comprises a second fixing plate, a second through hole formed in the middle of the second fixing plate and an anti-disengaging lock catch arranged on one side of the second fixing plate. The first fixing piece and the second fixing piece are mounted in the water bath box through connecting structures and can move in the length direction of the water bath box. The balloon dilatation catheter can be immersed into a water bath through the first fixing piece and the second fixing piece, and meanwhile, the tail end of the balloon dilatation catheter to be tested is fixed by the anti-falling lock catch on the second fixing piece, so that the catheter is prevented from shifting or swinging when high-pressure injection is performed into the balloon. Meanwhile, during testing, the box cover is closed, and liquid or conduit materials can be prevented from splashing when the conduit is broken.
