AI Technical Summary

Technical Problem

Existing technologies cannot effectively remove hardened phlegm crusts inside the tracheostomy tube, and mechanical gripping tools are difficult to follow curved paths and completely grasp the phlegm crusts, making operation inconvenient.

Method used

A tracheostomy tube sputum crust remover was designed, including a clamping component, an opening and closing component, an elastic reset component, a flexible arm, a handheld drive component, and a transmission component. By utilizing the combination of the flexible arm and multiple grippers, the sputum crust can be flexibly grasped and stably transmitted, ensuring the complete removal of the sputum crust.

Benefits of technology

It achieves non-damaging, complete grasping and efficient removal of phlegm crusts, improving the controllability and success rate of the removal process.

Abstract

The invention discloses a sputum scab remover for a trachea cannula, and belongs to the technical field of medical instruments. The cleaner comprises a clamping assembly, an opening and closing mechanism, an elastic reset piece, a flexible arm, a handheld driving assembly and a transmission assembly. The clamping assembly comprises a mounting base and a plurality of circumferentially-distributed clamping jaws, and the lower ends of the clamping jaws are hinged to the mounting base. The opening and closing mechanism comprises a driving sleeve capable of axially moving and a connecting rod mechanism connected with the driving sleeve and the clamping jaw; the elastic reset piece provides elastic force for closing the clamping jaw; the flexible arm is connected with the mounting seat and the handheld driving assembly; the handheld driving assembly comprises a driving mechanism in the shell; the transmission assembly is connected with the driving mechanism and the driving sleeve. The flexible arm adapts to the bent path of the trachea cannula, the sputum scab is grabbed in a wrapping mode through circumferential distribution of the multiple clamping jaws, stable and reliable action control is achieved through the transmission mechanism, and therefore the problem that an existing tool is difficult to go deep into the bent cannula and completely and reliably remove the attached sputum scab is solved.
