Air cutting type bridge frame control balance ventilation single-cavity lung isolation catheter

Abstract

The invention discloses an air cutting type bridge frame control balance ventilation single-cavity lung isolation catheter, and relates to the technical field of medical appliances. The air cutting type bridge frame control balance ventilation single-cavity lung isolation catheter is used for solving the problems of low safety and low balance ventilation efficiency of left and right lungs in the thoracic surgery by using other lung isolation catheters. The geometric distribution of forming holes in the catheter wall of the balance ventilation single-cavity lung isolation catheter controlled by an air cutting type bridge frame is utilized for solving the problem of risk due to easy bending of the catheter; through the geometric distribution, the catheter support intensity of the second opening hole region is enhanced through the geometric distribution. The air cutting type bridge frame control balance ventilation single-cavity lung isolation catheter comprises a main pipe tracheal catheter and a bronchial catheter, wherein the bronchial catheter communicates with one end of the main pipe tracheal catheter; the tail end of the bronchial catheter is provided with a first opening; at least two second hole forming regions with open holes are arranged on the lower end side wall of the main pipe tracheal catheter; a plurality of second hole forming regions with open holes are in the same or different transverse tangent plane or longitudinal tangent plane distribution in the three-dimensional space formed by the main pipe tracheal catheter and the bronchial catheter.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a single-cavity lung isolation catheter for air-cutting bridge controlled balanced ventilation. Background technique [0002] The double-lumen bronchial catheter has been used clinically for 40 years without a breakthrough improvement. The reason for the thick catheter is that there is a "separation" in the middle. The balance of ventilation, so there is "separation", so "coarse". The thick defect of the catheter causes damage to the oral cavity, vocal cords, and tracheal wall; it needs to be aligned and is prone to misalignment, and it needs to be intubated with a higher-end instrument for alignment; when the body position changes, it is easy to rotate and shift; it cannot meet Requirements for minimally invasive visualized cardiothoracic surgery in children; the most important thing is that it is easy to cause complete lung collapse or lung collapse on the surgical sid...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a single-cavity lung isolation catheter for balanced ventilation controlled by an air-cutting bridge, which is used to replace the traditional double-lumen tracheal catheter, solve the problem of thick passage outside the catheter, and solve the problem that the existing lung isolation catheter is prone to bending The technical problem that it cannot be used due to damage, and that the ventilation flow in the area of ​​the second opening is scattered easily affects the use effect
