Multifunctional visual single-cavity bronchial cannula

Abstract

The invention relates to a multifunctional visual single-cavity bronchial cannula. The multifunctional visual single-cavity bronchial cannula comprises a ventilation main pipe assembly, a main tracheacuff assembly, a bronchial cuff assembly, an intra-bronchial balloon assembly, a visual data system assembly, a flushing cavity assembly and a suction cavity assembly. Compared with the prior art, image signals are transmitted to a universal display through a camera at the front end to display video images in real time, rapid and accurate positioning of a single-cavity bronchial cannula is achieved, and therefore, cannulating to bronchial is completed accurately, rapidly, safely and effectively. The difficulty of single-cavity bronchial cannula and the complexity of operation are reduced, theoperation is simple, convenient and rapid, and the damage to human tissues is small. The overall outer diameter size of a breather pipe is reduced, cannula damage and cannula complications are reduced, and safety and comfort are higher. Besides, a camera module adopts a split type image processor, so that the problems that an image processor is large in heat productivity and prone to burning of internal tissues of a human body are solved, and the safety is better.

Description

technical field [0001] The invention relates to a medical device for establishing an artificial airway channel for a patient, which is applied to surgical anesthesia, rescue of critically ill patients, or other assisted breathing, in particular to a multifunctional visible single-lumen bronchial intubation tube. Background technique [0002] In anesthesia operations, single-lumen bronchial catheters and single-lumen bronchial intubation tubes are used to separate the lungs in thoracic surgery and lung surgery to keep the patient's lungs ventilated while isolating both lungs to avoid secretions from the lungs being operated on , interstitial fluid or blood into the other lung, causing infection of the lung that is not in operation and playing a protective role. [0003] At present, the existing single-lumen bronchial intubation tubes have a small inner diameter and a thicker outer tube diameter, resulting in greater damage to the intubation tube and more likely to cause intub...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing single-lumen bronchial intubation tubes have a small inner diameter and a thicker outer tube diameter, resulting in greater damage to the intubation tube and more likely to cause intubation complications during use. Hidden dangers of accidents and conflicts between doctors and patients; the existing single-lumen bronchial catheter has a simple structure, and needs to be assisted by a laryngoscope when used, and a bronchoscope is needed to assist in positioning. It is too large to improve the safety of anesthesia, and the bronchoscope equipment is expensive, easy to damage, and requires high technical operation, and each patient needs to be cleaned and disinfected after use, which increases the workload, and if the disinfection is not complete, it is easy to cause cross-infection; the existing single The lumen bronchial catheter lacks the endobronchial suction line under the cuff, and cannot absorb the interstitial fluid, secretions or blood in the lungs; most of the video acquisition modules of the existing visible single-lumen bronchial catheters use camera image acquisition modules and The transmission module, data transmission module and other circuits are integrally formed, the cost is high, and the image processor generates a lot of heat, which is easy to burn the internal tissues of the human body and other problems
