Special endotracheal tube for lung transplantation

Abstract

The invention relates to a special endotracheal tube for lung transplantation, which is particularly used for supplying air for lungs of a patient during lung transplantation or pulmonary resection and belongs to the technical field of medical instruments. The special endotracheal tube mainly comprises an outer cannula and an inner cannula, and the inner cannula is fixed in the outer cannula. An outer cannula air sac is arranged on the outer surface of the middle of the outer cannula. A first inner cannula air sac and a second inner cannula air sac are successively arranged on the outer surface of the lower portion of the inner cannula. The special endotracheal tube is simple, compact and reasonable in structure and simple and convenient in operation, the single inner cannula is used for carrying out breathing support for the lung of the patient, the pressure of the trachea is low, and the possibility of injury of the lung on a non-surgical side due to mechanical breathing is reduced; the bronchia on a surgical side is closed by the air sacs, so that liquid of the lung on the surgical side cannot enter the non-surgical side and the trachea, and breathing support leakage can be avoided while the bronchia is sutured; and the inner cannula is taken out after surgery is finished, the outer cannula is remained to carry out breathing support, and sufferings caused by replacement of a catheter and risks of injury of the trachea are avoided.

Description

technical field [0001] The invention relates to a special trachea tube for lung transplantation, specifically for breathing support in lung transplantation or lung resection, and belongs to the technical field of medical devices. Background technique [0002] During lung transplantation or lung resection, breathing support is required for the patient. In the prior art, a double-lumen bronchial catheter is generally used for respiratory support during the operation. [0003] The double-lumen bronchial catheter adopts a double-lumen structure, because the limitation of the diameter of the trachea of ​​the human body results in a smaller diameter of the single lumen, and the compliance of the lungs of patients undergoing lung transplantation is poor. During one-lung surgery, one-lung ventilation on the other side can easily create high airway pressure, which can lead to lung damage. After surgery, the double-lumen bronchial tube must be replaced with a single-lumen bronchial ...

AI Technical Summary

Problems solved by technology

The double-lumen bronchial tube is withdrawn, on the one hand, it is easy to cause air leakage; on the other hand, various liquids such as bleeding in the lung on the operated side will enter the tracheal tube

In the process of replacement, it is easy to cause the patient's tracheal intubation injury due to improper operation, and it may also cause hypoxia due to the suspension of respiratory support, which will bring pain to the patient.
