Embodiment 1

[0077] Such as figure 1 As shown, the present invention provides a double-lumen tube, including an endotracheal tube 1, a partition plate 12 arranged along the length direction of the endotracheal tube 1 so that the inner cavity of the endotracheal tube 1 is divided into two independent ventilation chambers 11, The endotracheal tube 2 is inserted into the two ventilation chambers 11 from the bottom of the endotracheal tube 1, and the ventilation device 3 and the adjustment device 4 are arranged on the top of the endotracheal tube 1 from bottom to top; the ventilation device 3 is in communication with the air source 100 Oxygen is supplied to the two ventilation chambers 11; the ventilation device 3 is fixedly connected to the partition plate 12; the regulating device 4 is fixedly connected to the endotracheal tube 2;

[0078] In Embodiment 1, the endotracheal tube 2 can rotate axially relative to the endotracheal tube 1 through the ventilation device 3 ; When the endotracheal ...

Embodiment 2

[0096] The difference between Embodiment 2 and Embodiment 1 is that at least one of the two endotracheal tubes 2 can rotate relative to its axis through the adjustment device 4 , and the endotracheal tube 2 can be stretched relative to the endotracheal tube 1 through the adjustment device 4 . In this embodiment, the ventilation device 3 is fixedly connected to the fixed seat 13, the ventilation device 3 cannot rotate relative to the endotracheal tube 1, so the partition plate 12 cannot rotate, and the stretching and rotation of the endotracheal tube 2 are all through the adjustment device 4 realized. The difference between the technical solution of this embodiment 2 and the embodiment 1 is that the ventilation device 3 is fixedly connected to the fixed seat 13 , and the adjustment device 4 is connected to the top of the ventilation device 3 by rotation.

[0097] As an optional embodiment, the number of adjustment devices 4 is two, and the two adjustment devices 4 are rotated s...

Embodiment 3

[0100] The difference between Embodiment 3 and Embodiment 2 is that the endotracheal tube 2 can rotate relative to the axis of the endotracheal tube 1 through the ventilation device 3, and at least one of the two endotracheal tubes 2 can rotate relative to its axis through the adjustment device 4 , the endotracheal tube 2 can be stretched relative to the endotracheal tube 1 through the adjustment device 4 .

[0101] The structure and connection relationship between the ventilation device 3 and the endotracheal tube 1 in this embodiment 3 are the same as the scheme in embodiment 1, and the connection and structural relationship between the adjustment device 4 and the ventilation device 3 are the same as the scheme in embodiment 2 same.

[0102] The present invention also provides a double-lumen tube intubation method, comprising the following steps:

[0103] Step A: Prepare for surgery, prepare corresponding surgical tools before intubation, and adjust the bending direction of...

Abstract

The invention provides a double-lumen tube and an intubation method. The double-lumen tube comprises a tracheal intubation tube, a partition plate arranged along the length direction of the tracheal intubation tube so as to partition the tracheal intubation lumen into two independent ventilation chambers, a tracheal tube inserted into the two ventilation chambers from the bottom of the tracheal intubation tube, and a ventilation device and an adjustment device arranged at the top of the tracheal intubation tube from the bottom to the top in turn; The ventilation device is in communication withan air source for supplying gas to the two ventilation chambers; The ventilator is fixedly connected with the partition plate; The adjusting device is fixedly connected with the tracheal tube; The tracheal tube is rotatable relative to the axis of the tracheal intubation through the ventilator. And / or at least one of the two tracheal tubes is rotatable relative to its axis by means of an adjusting device; The tracheal tube is telescopic with respect to the tracheal intubation by means of an adjusting device. As that split structure design is adopt, the tracheal tube can be telescoped and rotate, the accuracy of the intubation is improved, the success rate is high, the adjustability is good, and the damage of the tissue is reduced.

Description

technical field [0001] The invention relates to the technical field of medical hygiene materials, in particular to a telescopic and rotatable double-lumen tube and an intubation method. Background technique [0002] At present, the most clinically used double-lumen tubes are divided into left double-lumen tube and right double-lumen tube. There are ventilation ports at the head end of the tube, which can be connected to a ventilator for mechanical ventilation; the tail end of the double-lumen tube has left and right double-cavity openings, and the left opening of the left tube is the main road, and there is an about 18mm airbag at the end of the main road. 15mm above the air bag is the opening of the right lumen, which is only a fixed oblique opening with the tip close to the left lumen. During intubation and ventilation, insert the left main channel of the tracheal tube into the left main bronchus, and align the right side hole with the right bronchus for ventilation to ac...
