Visual multifunctional double-cavity bronchial cannula

Abstract

The invention provides a visual multifunctional double-cavity bronchial cannula. The visual multifunctional double-cavity bronchial cannula comprises a double-cavity tube, a ventilation main tube assembly, a ventilation branch tube assembly, a main trachea cuff assembly, a bronchial cuff assembly, a visual data system assembly, a flushing assembly and a suction cavity assembly. In the intubation process, the double-cavity tube is bent by a human physiological angle through a directional guide wire, an image signal is transmitted to a universal display through a camera at the front end to display a video image in real time, and the double-cavity bronchial cannula is quickly and accurately positioned, so that the operation of intubation to the bronchus is accurately, quickly, safely and effectively completed, the difficulty of the double-cavity bronchial cannula and the complexity of the operation are reduced, the operation is simple, convenient and quick, and the damage to human tissuesis small; and meanwhile, a camera module adopts a split image processor (namely, the image processor is positioned outside the human body during intubation), so that the problems that the image processor is large in heat productivity, the internal tissues of the human body are easily burnt and the like 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 visible multifunctional double-lumen bronchial intubation tube. Background technique [0002] Clinically, double-lumen bronchial catheters are widely used in thoracic surgery to separate the lungs, to keep the patient's lungs ventilated while isolating the lungs, and to prevent secretions, interstitial fluid or blood from the lung being operated on from entering the other lung. In the lungs, the lungs that are not in operation are protected from infection. [0003] At present, the existing double-lumen bronchial catheter has a simple structure and needs to be assisted by a laryngoscope when used, and a bronchofiberscope is needed to assist in positioning. The trauma is large when used, the induction time of anesthesia is long, an...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing double-lumen bronchial catheter has a simple structure and needs to be assisted by a laryngoscope when used, and a bronchofiberscope is needed to assist in positioning. The trauma is large when used, the induction time of anesthesia is long, and the drug consumption is large, which cannot improve the safety of anesthesia. , and the fiberoptic bronchoscope equipment is expensive, easy to damage, and has high requirements for technical operations, and each patient needs to be cleaned and disinfected after use, which increases the workload, and incomplete disinfection is likely to cause cross-infection

[0004] Moreover, the existing visual double-lumen bronchial catheter camera module has an integrated structure, and the temperature is relatively high, which is likely to cause the video acquisition module of the existing video endotracheal intubation catheter to use camera image acquisition module and transmission module data transmission module, etc. The circuit is 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. In addition, during the intubation process, the patient’s secretions stick to the surface of the camera and cannot be clearly seen, which will cause affect the intubation process
