Visible side-guided tracheal tube member

Abstract

The invention discloses a visual side-guided tracheal tube member. The upper side of the visible side-guided tracheal tube member is a machine end, the lower end is a patient end, the visible side-guided tracheal tube member is provided with an air bag near the wall of the patient end, an axially closed lateral opening is arranged at the tube wall at one side of the lower end of the air bag, the opening direction of the lateral opening is perpendicular to the longitudinal axis of the chamber of the tracheal tube, and laterally directed to the side surface; the tube wall of the lateral openingis a curved lateral-bending side wall, and a micro camera is disposed in the curved lateral-bending side wall. The process of feeding the tracheal tube into the bronchus by means of the equipment canbe observed through the longitudinal micro camera on the side wall of the lateral opening by a display connected thereto. The proper position and depth of the occlusion tube in the bronchus are clearly located to meet the clinical choice and usage of left and right lung isolation and single lung ventilation. The visual side-guided tracheal tube member makes the placement and positioning of the tracheal tube simple, accurate and reliable.

AI Technical Summary

Problems solved by technology

[0005] 1) The total tube diameter is thick, the texture is relatively hard, the relative damage to the trachea and tissues is large, and the irritation is strong

[0006] 2) Can not be used for a long time

If the patient needs to continue respiratory support after the operation, the catheter is often removed and replaced with a single-lumen endotracheal catheter, and the replacement process not only increases tissue damage, but also may cause other accidents due to the difficulty of re-intubation

[0007] 3) During the operation, due to body position changes and surgical operations, sometimes the position of the catheter will shift and slip out of the bronchi, making it difficult to adjust the position, which will affect the ventilation method required by the operation and increase the difficulty of the operation

[0008] 4) The operation of intubation positioning has certain technical difficulties, and the precise positioning still depends on the fiberoptic bronchoscope

[0010] 1) It is difficult to accurately place the target bronchus, and it is necessary to use a bronchoscope to accurately locate it

[0011] 2) It takes a long time to complete the tube placement and it is easy to slip off with body position changes, and it is difficult to position the tube again after slipping off

[0012] 3) The application of anesthesia in right thoracic surgery is often limited

[0013] 4) There are problems of complex manufacturing process and high cost

The main problem is that the camera is placed in the lumen, so that the inner diameter of the distal end of the endotracheal tube is significantly narrowed, which not only affect
