Cannula fixing and correcting device with supporting structure after tracheotomy

By designing a cannula fixation and correction device with a support structure after tracheotomy, the problems of local tissue ischemia and necrosis, cannula displacement and chronic inflammation caused by the weight of the tube, traction force and placement angle in long-term tracheotomy patients are solved. It achieves precise fixation, support and timely warning, and improves the patient's rehabilitation effect.

AI Technical Summary

Technical Problem

The recovery process of patients with long-term tracheostomy is easily affected by factors such as the weight of the tube, traction force, and placement angle, leading to problems such as local tissue ischemia and necrosis, cannula displacement, chronic inflammation, and granulation tissue hyperplasia.

Method used

Design a cannula fixation and correction device with a support structure after tracheotomy, including a protective pad, a neck limiter, a shoulder limiter, an adjusting rod, a support ring, a traction warning mechanism, a gas leak detection mechanism, and a buffer mechanism. Through the synergistic effect of these components, the cannula and connecting tube are accurately fixed, supported, and monitored to prevent adverse effects.

Benefits of technology

It effectively prevents the connecting tube from tilting in all directions, reduces pressure on the tissues around the fistula, ensures the quality of fistula recovery, provides timely warning of gas leaks, reduces the risk of injury to patients, and improves rehabilitation outcomes.

Abstract

The invention relates to the technical field of medical instruments, in particular to a cannula fixing and correcting device with a supporting structure after tracheotomy. The tilted end of the protective base plate is fixedly connected with a neck limiting piece, and one end of the protective base plate is further fixedly connected with two groups of shoulder limiting pieces which are arranged in a hook shape; sliding grooves are formed in the opposite sides of the shoulder limiting pieces, adjusting rods are arranged in the sliding grooves, and correction modules are fixedly connected to the centers of the adjusting rods. A limiting bolt is further arranged above the shoulder limiting piece, and the limiting bolt is in screwed connection with the adjusting rod; the protective base plates are matched with the shoulder limiting pieces and clamped on the two sides of the shoulders of the patient to achieve limiting and fixing; the supporting ring is located above the sleeve, follow-up connection of the communicating pipe and the sleeve is facilitated, the communicating connector is clamped above the supporting ring, the bottom of the communicating connector is in butt joint with the sleeve, the supporting ring can effectively support the communicating pipe, the trachea is prevented from inclining all around, the communicating pipe is prevented from driving the sleeve to press tissue around the fistula, and the recovery quality of the fistula is guaranteed.
