Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a device for preventing the dislodgement of endotracheal tubes. Background Technology

[0002] Tracheostomy, or tracheotomy, requires special attention in the care of tracheostomy tubes, airways, skin, and diet. A tracheal tube is inserted into the trachea or bronchi to create a temporary artificial breathing channel for patients, especially those unable to breathe independently. After discharge, tracheostomy patients are responsible for cleaning and inserting the tube themselves, and tube dislodgement is a possibility. Currently, many tracheal tubes are secured by wrapping a rope around the neck, which is uncomfortable, prone to loosening, and lacks a comprehensive anti-dislodgement detection structure. This makes it difficult to provide timely warnings in the early stages of tube dislodgement, hindering timely patient awareness and making it inconvenient for assisted gas-assisted isolation, resulting in poor safety.

The pressure sensor 403 senses the pressure change. Similarly, if the double-sided adhesive 1021 on the skin comes loose, the travel of the bonding assist spring 504 increases. The anti-detachment detection pressure sensor 501 can detect the decrease in pressure, and the alarm controller 601 can control the alarm assist light 602 to light up and sound an alarm. The gas filter installation cylinder 701 can be rotated to perform the disassembly work.
