AI Technical Summary

Technical Problem

Existing nasopharyngeal catheter adapters are unstable and cumbersome to operate, and the guidewires are poorly adaptable to complex anatomical structures, affecting the smoothness and safety of insertion.

Method used

The adapter assembly, consisting of limiting steel balls and springs, combined with the guide wire mechanism of movable ball and rotation space, enables convenient fixing and customizable guide wire length.

Benefits of technology

It improves the connection stability of the adapter interface and the flexibility of the guide wire, ensuring smooth and safe insertion, and reducing operational complexity and the risk of dislodgement.

Abstract

The present application relates to a kind of nasopharyngeal catheter, comprising: catheter body;Adapter mechanism, adapter mechanism includes adapter body and adapter component, adapter body is connected with catheter body, adapter component is arranged on adapter body, adapter component includes fixed pipe, abutment pipe and limit steel ball;Guide wire mechanism, guide wire mechanism is inserted in catheter channel, guide wire mechanism includes multiple mutually connected movable components, each movable component includes movable body and movable ball, the inside of movable body has the rotation space matched with movable ball, movable body is provided with the insertion opening that communicates with rotation space, movable ball is arranged at the top of movable body, each movable ball passes through the insertion opening of previous movable component, and can be rotatably arranged in the rotation space of previous movable component. To overcome the defects that nasopharyngeal catheter in the prior art is unstable when connecting with outside adapter and guide wire is poor in adaptability to complex environment.
