TUBE-WALL-FREE RIGHT-SIDED DOUBLE-LUMEN BRONCHIAL CATHETER

Abstract

A tube-wall-free right-sided double-lumen bronchial catheter, consisting of a tube-wall-free bronchial catheter body and a double-lumen ventilation catheter body. For the tube-wall-free bronchial catheter body, by means of a plurality of bronchial struts, an upper end is connected to the inner wall of a bronchial cuff and a lower end is connected to an annular opening, and no connection is present among the bronchial struts. When right lung single-lung ventilation is performed, the tube-wall-free bronchial catheter body enters a right main bronchus, the direction and position of the catheter body do not need to be adjusted, the tube-wall-free structure of the tube-wall-free bronchial catheter body can achieve complete opening of the upper lobe of the right lung, and the optimal ventilation effect of the right lung single-lung ventilation is ensured. Poor ventilation of the right upper lung is avoided, time consumption is shortened, airway injuries are reduced, and related complications are reduced.

Description

SPECIFIC EMBODIMENTS

[0020] The present invention will be further described below with attached drawings, the description doesn't constitute a limitation of the present invention.

[0021] Referring to the pic 1 and 2, the tube-wall-free right-sided double-lumen bronchial catheter tube consists primarily of the tube-wall-free bronchial catheter body 1 and double-lumen ventilation catheter body 2. The tube-wall-free bronchial catheter body 1 comprises the bronchial cuff 1.1, several bronchial struts 1.2 and the annular opening 1.3. The bronchial catheter of the lower section of the bronchial cuff 1.1 in the tubeless wall type bronchial catheter 1 has no tubular wall structure, and the bronchial catheter of the tubeless wall structure is connected to the inner wall of the bronchial cuff 1.1 via the upper end of a plurality of bronchial struts 1.2, the lower end of a plurality of bronchial struts 1.2 connected to the annular opening 1.3, bronchial struts 1.2 connected to each other without wall structure. The mentioned double-lumen ventilation catheter body 2 consists of the main tracheal catheter 2.1, the right bronchial catheter 2.2, the main tracheal cuff 2.3, the main tracheal catheter opening 2.4, the main tracheal cuff inflation device, the bronchial cuff inflation device 2.5, among them, the lower end of the right bronchial catheter connected to the tube-wall-free bronchial catheter body 1. Double-lumen ventilation catheter body 2 is a tube with two-lumen structure, with the left side being the main tracheal catheter 2.1 and the right side being the right bronchial catheter 2.2. The main tracheal cuff 2.3 is in the lower section of the double-lumen ventilation catheter body 2, and below the main tracheal cuff 2.3 is the main tracheal catheter opening 2.4, which is a beveled opening facing downward to the left. The main tracheal cuff inflation device is connected to the main tracheal cuff 2.3 via the main tracheal cuff connection tube 2.6 parallel to the double-lumen ventilation catheter body 2. The bronchial cuff inflation device 2.5 is connected to the bronchial cuff 1.1 via the bronchial cuff connection tube 2.7 parallel to the double-lumen ventilation catheter body 2.

[0022] The main tracheal cuff connection tube 2.6 and the bronchial cuff connection tube 2.7 are thin tubes.

[0023] In the specific implementation of the present invention, when the a tube-wall-free bronchial catheter body enters the right main bronchus and the bronchial cuff is flush with the level of the tracheal bulge of the bronchial cuff, the main tracheal catheter cuff and the bronchial cuff are inflated, and during the process of OLV, there is no need for adjusting the catheter direction and position, and the tube-wall-free structure of the bronchial catheter can realize the complete opening of the right upper lobe of the lung to guarantee the optimal ventilating effect of OLV.

[0024] On the basis of the traditional RDLT, the present invention abandons the previous structure of the right bronchial catheter, breaking through the barrier of the tube, and the right bronchial catheter adopts the structure of the tubeless wall, which changes the method of relying on the wall, the lumen, and the structure of the side hole in the traditional catheter to carry out ventilation, and radically solves the problem of misalignment, secretion blockage, and the problem of the side hole, which are the most common problems of the right lung, and the most common problems of the right lung. It can fundamentally solve the problem of poor ventilation caused by misalignment of side holes, obstruction of side holes by secretions, and blocking of the tracheal opening by the tube wall, which not only saves the anesthesiologist's time for adjusting the positioning, but also maximally protects the patient's OLV effect and avoids various complications caused by poor ventilation due to the defect of the catheter. The design of the present invention of the tubeless wall bronchial catheter is simple, but it is easy to manufacture and has remarkable effects and strong Clinical practical value. If it can be popularized and applied, it will play a significant clinical value.

[0025] The foregoing is only a preferred embodiment of the present invention model, and it should be noted that a number of improvements and additions, without departing from the method of the present invention model, can be made by ordinary technical personnel, which shall also be considered to be within the scope of protection of the present invention model.
