AI Technical Summary

Problems solved by technology

[0003] At present, in order to achieve lung isolation surgery, multiple pipelines are installed on the double-lumen tube, which increases the volume of the tube cavity, resulting in increased respiratory dead space, which is not conducive to lung ventilation for patients undergoing lung isolation surgery.
At present, the double-lumen endotracheal tube has two independent tubes, and the tubes need to be replaced frequently to achieve lung isolation, and the operation is relatively complicated

[0031] Please refer to Figure 1 to Figure 3 , figure 1 A bottom view of a single-head double-lumen endotracheal catheter according to an embodiment of the present application; figure 2 A cross-sectional view of a single-head double-lumen endotracheal catheter according to an embodiment of the present application; image 3 This is a state diagram of the use of a single-head double-lumen endotracheal tube according to an embodiment of the present application.

[0032] A single-head double-lumen tracheal catheter, comprising a single-head gas catheter 1, an airway three-way device 2 and a double-lumen gas catheter 3 connected in sequence;

[0033] The materials of the single-ended gas conduit 1 , the airway three-way device 2 and the double-lumen gas conduit 3 in this embodiment are all medical materials, which can be used for human intubation.

[0034] The double-lumen gas catheter 3 includes a left-lumen trachea 31 and a right-lumen trachea 32. The heads of the left-lumen ...

Embodiment 2

[0038] Please refer to Figure 1 to Figure 3 , figure 1 A bottom view of a single-head double-lumen endotracheal catheter according to an embodiment of the present application; figure 2 A cross-sectional view of a single-head double-lumen endotracheal catheter according to an embodiment of the present application; image 3 This is a state diagram of the use of a single-head double-lumen endotracheal tube according to an embodiment of the present application.

[0039] This embodiment provides a single-head dual-lumen endotracheal catheter, which is basically the same as the single-head dual-lumen endotracheal catheter provided in Embodiment 1, and the similarities will not be repeated. The gas conduit 1 is a reinforced gas conduit, and a spiral steel wire is arranged in the cavity of the single-ended gas conduit 1 .

[0040] In this embodiment, the single-ended gas conduit 1 is a reinforced gas conduit commonly used in the field, which is convenient for purchase and replaceme...

Embodiment 3

[0042] Please refer to Figure 1 to Figure 3 , figure 1 A bottom view of a single-head double-lumen endotracheal catheter according to an embodiment of the present application; figure 2 A cross-sectional view of a single-head double-lumen endotracheal catheter according to an embodiment of the present application; image 3 This is a state diagram of the use of a single-head double-lumen endotracheal tube according to an embodiment of the present application.

[0043] This embodiment provides a single-head dual-lumen tracheal catheter, which is basically the same as the single-head dual-lumen tracheal catheter provided in Embodiment 1, and the similarities will not be repeated. The difference is that the first The opening of the opening is larger than the sum of the openings of the second opening and the third opening.

[0044] In the present embodiment, the opening size of the first opening opposite to the single-headed gas conduit 1 is larger than the combined opening siz...

Abstract

The invention provides a single-head double-cavity tracheal catheter, and relates to the field of tracheal catheters. A single-head double-cavity tracheal catheter comprises a single-head gas catheter, an airway three-way device and a double-cavity gas catheter which are sequentially connected. The double-cavity gas conduit comprises a left cavity gas pipe and a right cavity gas pipe, a Y-shaped vent groove is formed in the gas channel three-way device, a first opening of the vent groove is opposite to the single-head gas conduit, and a second opening and a third opening of the vent groove are opposite to the left cavity gas pipe and the right cavity gas pipe of the double-cavity gas conduit respectively. By arranging the single-head gas catheter, the airway three-way device and the double-cavity gas catheter which are connected in sequence, the airway three-way device can be adjusted to achieve the ventilation condition of a single lung or double lungs.

Description

technical field [0001] The present application relates to the field of endotracheal tubes, in particular to a single-head double-lumen endotracheal tube. Background technique [0002] Since the development of lung isolation technology, thoracic surgery has developed by leaps and bounds. Lung isolation is a commonly used breathing management method during general anesthesia in thoracic surgery. It separates the ventilation pathways of the left and right lungs, and ventilates the lungs in different ways according to the needs of the disease, providing effective ventilation while preventing disease. The blood and sputum of the lateral lung flow into the healthy side. Lung atrophy on the operative side can provide good exposure for the operator, and is used in the treatment of certain thoracic diseases such as bronchopleural leak and tracheobronchial rupture, massive hemoptysis, pulmonary contusion, bullous pneumothorax, unilateral lung infection, bronchial surgery, etc. Moder...
