Tube-wall-free right side double-lumen bronchial catheter

Abstract

The invention relates to the technical field of medical instruments, in particular to a tube-wall-free right side double-lumen bronchial catheter . The tube-wall-free right side double-lumen bronchial catheter is composed of a tube-wall-free bronchial catheter body and a double-lumen ventilation catheter body. The upper end of the tube-wall-free bronchial catheter body is connected with the inner wall of a bronchial cuff through a plurality of bronchial columns, the lower end is connected with an annular opening, and the bronchial columns are not connected. The tube-wall-free structure of the right side bronchial catheter is designed, the structure is simple, the effect is clear, and the clinical practicability is high; and when right lung single-lung ventilation is conducted, the tube-wall-free type bronchial catheter enters the right main bronchial tube, the direction and the position of the catheter do not need to be adjusted, the tube-wall-free structure of the bronchial catheter can achieve complete opening of the upper lobe of the right lung, and the optimal ventilation effect of right lung single-lung ventilation is ensured. And poor ventilation of the right upper lung caused by tube wall blocking or uneven hole alignment of the side wall is avoided, time consumed for adjusting the catheter is shortened, airway injuries caused by the adjustment are reduced, and related complications caused by insufficient ventilation are reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a wall-less right double-lumen bronchus catheter. Background technique [0002] The double-lumen bronchial catheter can isolate the left lung and the right lung, realize single-lung ventilation, provide a good surgical field for surgery, and prevent the blood and secretions of the affected lung from infecting the healthy lung. It is the most commonly used ventilation in thoracic surgery. tool. [0003] The commonly used double-lumen bronchial catheters are mainly divided into left double-lumen bronchial catheters and right double-lumen bronchial catheters. When using a double-lumen bronchial catheter for lung isolation ventilation, in order not to affect the surgical operation, the bronchial catheter is best placed in the non-operated lung, that is, the left double-lumen bronchial catheter is selected for right-sided thoracic surgery, and the right double-lumen bronchial...

AI Technical Summary

Problems solved by technology

In clinical work, when using the right double-lumen bronchus catheter for right-lung one-lung ventilation, the anesthesiologist needs to spend time and energy to adjust the position and direction of the catheter to ensure the ventilation of the right upper lobe, but the position of the bronchial opening of the right upper lobe Poor alignment of the catheter position due to large variability, and poor ventilation of the upper lobe of the right lung due to sputum, blood or other secretions blocking the side hole often occur, which is more likely to cause insufficient ventilation and oxygenation , atelectasis of the upper lobe of the right lung, severe imbalance of ventilation blood flow ratio and a series of complications
