Novel ventilating and sealing multifunctional tube for bronchi

Abstract

The invention relates to the technical field of medical devices, and provides a novel ventilating and sealing multifunctional tube for bronchi. The novel ventilating and sealing multifunctional tube for bronchi includes a multifunctional tube body, wherein the surface of the multifunctional tube body is provided with a main cuff, a high-position cuff and an annular cuff, a first connecting tube isfixedly connected to the surface of the main cuff, and the main cuff is connected to the multifunctional tube body through the first connecting tube; and a second connecting tube is fixedly connectedto the surface of the high-position cuff, the high-position cuff is connected to the multifunctional tube body through the second connecting tube, and a third connecting tube is fixedly connected tothe surface of the annular cuff. Bilateral lung fields of a bronchus on an arbitrary side can be ventilated separately at the same time, and meanwhile a good function of sputum sucking treatment is achieved; the fixing mode is simple and reliable, blockage or ventilation can be achieved for even patients with abnormal anatomy of the opening of the upper right lung, realization possibilities of ventilation of any singular-side lung are increased, the medical efficiency is improved, all groups of people with different anatomical structures are taken into account, and waste of medical materials is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a novel multifunctional tube for bronchial ventilation blocking. Background technique [0002] Nowadays, unilateral bronchial ventilation technology has been widely used in various thoracic surgery, atrial fibrillation ablation surgery in cardiac surgery, left atrial appendage resection surgery, unilateral lung lavage surgery in respiratory department, etc. Bronchial catheters, bronchial occlusion tubes, etc. are realized. [0003] However, in the prior art, there are following defects: 1. The existing double-lumen bronchial catheter or bronchial occlusion tube must be inserted into the designated lung. It is necessary to adjust during the operation, but the adjustment may be severely limited due to the infiltration of blood and mucus in the lung field after the operation, and the blurred view of the bronchoscope; 2. It is difficult to suck sputum with the existing bronc...

Problems solved by technology

[0003] However, in the prior art, there are following defects: 1. The existing double-lumen bronchial catheter or bronchial occlusion tube must be inserted into the designated lung. It is necessary to adjust during the operation, but the adjustment may be severely limited due to the infiltration of blood and mucus in the lung field after the operation, and the blurred view of the bronchoscope; 2. It is difficult to suck sputum with the existing bronchial occlusion tube; 3. In the case of high lung opening and right upper lung pole parallel to the tracheal carina, the existing technology still lacks a simple solution; 4. After the existing double-lumen bronchial catheter and bronchial blocking tube are fixed, they may be displaced due to surgery
