Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0021] Such as figure 1 As shown, a sleeve-type tracheal intubation tube with a variable diameter includes a double-bag side-hole bronchial tube 1 and a variable inner-diameter sheath 7, and the variable-inner-diameter sheath 7 is inserted into the double-bag side-hole bronchus In the intubation tube 1, the front end of the double-bag side-hole bronchial intubation tube 1 is covered with a first air bag 2 and a second air bag 3, and the rear end of the double-bag s...

Abstract

A disclosed sleeve type trachea cannula with a variable pipe diameter comprises a double-bag bronchial cannula body with side holes and a sheath tube with the variable inner diameter, the sheath tube with the variable inner diameter is inserted into the double-bag bronchial cannula body with the side holes, the front end of the trachea cannula body is sleeved with a first air bag and a second air bag, a breathing hole is formed in the portion, between the first air bag and the second air bag, of the tube body, a blocking air bag is arranged at the front end of the sheath tube with the variable inner diameter, and when the sheath tube with the variable inner diameter is inserted into the double-bag bronchial cannula body with the side holes, the blocking air bag crosses the breathing hole and blocks the tube body of the double-bag bronchial cannula with the side holes after being inflated. The tube diameter of the sheath tube with the variable inner diameter of the trachea cannula can be adjusted according to needs, the aim of ventilating the lung or blocking the bronchus on any side can be achieved without replacing sheath tubes with different tube diameters, and the difficulty and the risk of surgical operation are reduced; and meanwhile, the tube diameter of the sheathing canal is convenient to adjust, the tube diameter of the sheathing canal can be adjusted by pressing down or pulling up, and operation is convenient.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a sleeve-type tracheal intubation tube with variable diameter. Background technique [0002] The tracheal intubation tubes commonly used in one-lung ventilation surgery include double-lumen endobronchial tubes (DLTs) and single-lumen bronchial tubes. The double-lumen bronchial tube has a structure of one tube and two lumens, with two sections and two openings. One opening of the tube is located in the tracheal section of the tube. The other opening is located in the side bronchus segment. Although such a structure satisfies the function of isolating the affected bronchus, the outer diameter of the double-lumen bronchus catheter is relatively thick, and it is very easy to damage the respiratory tract during intubation, especially the variation of the right upper lung bronchus Larger, when the right double-lumen tube is used, it is easy to block the opening of the right upper lung an...
