Single-cavity multi-bag trachea catheter

Abstract

The invention relates to a trachea catheter, in particular to a trachea catheter for a thoracic cavity operation and discloses a single-cavity multi-bag trachea catheter. The trachea catheter comprises a trachea catheter and a catheter air bag arranged on the outer wall of the trachea catheter, wherein the trachea catheter air bag is connected with a trachea catheter air bag inflation tube; the lower end of the trachea catheter is connected with a bronchus catheter of which the inner diameter is smaller than that of the trachea catheter; the bronchus catheter is provided with an outer air bag of the bronchus catheter, and the outer air bag of the bronchus catheter is connected with an outer air bag inflation tube of the bronchus catheter; and a connecting part of the bronchus catheter and the lower end of the trachea catheter is reserved with a trachea catheter opening and provided with an opening sealing component. According to the technical scheme of the invention, through the arrangement of the opening sealing component, the single-cavity trachea catheter can be used for realizing all functions of a double-cavity trachea catheter, thereby various defects of too thick outer diameter, too thin inner diameter during ventilating of the lung at a single side, more connecting tubes, inconvenient operation, too large mechanical dead space being not suitable for child operations, and the like of the traditional double-cavity trachea catheter are overcome. The single-cavity double-outlet trachea catheter can be used for child thoracic cavity operations, solves the problem that a double-cavity trachea catheter for children is not provided for the child thoracic cavity operations at present and provides a safer guarantee for external chest anesthesia of children.

Description

technical field [0001] The present invention relates to a tracheal tube, in particular to a tracheal tube for thoracic surgery. Background technique [0002] When performing thoracotomy for patients, it is necessary to temporarily stop the ventilation of the lung on the side of the operation to facilitate the operation, which is usually achieved through unilateral ventilation of the double-lumen endotracheal tube. In addition, before or during the operation, both lungs need to be ventilated at the same time. At present, the double-lumen endotracheal catheter is generally used to achieve the above function, that is, the double-lumen endotracheal catheter is used to ventilate the left and right lungs respectively. . Its structure is: the traditional double-lumen tube has two lumens, each corresponding to an outlet, and there are two air bags up and down on the outside. The upper air bag blocks the trachea, and the lower air bag blocks the main bronchus on one side. It is sma...

Problems solved by technology

[0005] The present invention aims at the disadvantages in the prior art that the outer diameter of the endotracheal tube is too thick, the inner diameter of one side of the inner cavity is too thin, the mechanical dead space is too large, too many connecting tubes, and cannot be used for children's surgery, etc., and provides a single-lumen tube A single-lumen endotracheal tube with the same outer diameter, using one lumen to achieve the effect of two lumens
