Improved visual single-lumen bronchial catheter

Abstract

The invention is applicable to the technical field of medical instruments, and provides an improved visual single-lumen bronchial catheter which comprises a catheter inserted into a trachea and connected with a branch tracheal catheter; the branch gas guide pipe exhaust port is connected to the branch gas guide pipe; the side port exhaust port is formed in the guide pipe; the side wall type opening is formed in the branch air catheter and used for increasing the opening area corresponding to the right upper lung opening; a main balloon installed in the catheter; the branch air guide pipe outer air bag is mounted on the branch air guide pipe; the branch air guide pipe inner air bag is mounted in the branch air guide pipe; the side opening outer air bag is installed on one side of the side opening exhaust port, left lung ventilation is achieved after the main air bag, the branch air catheter outer air bag and the branch air catheter inner air bag are inflated and expanded, and right lung ventilation is achieved after the main air bag, the branch air catheter outer air bag and the side opening outer air bag are inflated and expanded; the camera shooting assembly is installed on the guide pipe and used for positioning the position. The side wall type opening is formed, and ventilation and residual gas discharging of the right upper lung are not affected.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to an improved visible single-lumen bronchial catheter. Background technique [0002] One-lung ventilation refers to the state of keeping only one lung ventilated. This technique is mainly used in the process of promoting surgical field exposure or anatomically isolating one lung from another lung pathologically. The double-lumen bronchial catheter is a commonly used medical device for one-lung ventilation, but the hard tube diameter of the double-lumen bronchial catheter is not only difficult for tracheal intubation, but also more likely to cause airway damage. Compared with the double-lumen bronchial catheter, the single-lumen bronchial catheter The catheter tube is thin, the difficulty of intubation is low, and the airway damage is small, and good clinical application results have been achieved. [0003] However, there are some problems with the existing single-lumen bro...

Problems solved by technology

However, there are three problems: 1. The remaining air in the lung on the surgical side cannot be effectively discharged, which affects the exposure of the surgical field; 2. The side hole of the tracheal tube is easily blocked by the inside of the airway, which affects the ventilation effect; 3. The bronchial part is not suitable for use Right lung, unable to effectively ventilate the right upper lung or expel residual air from the right upper lung;

However, there are two problems: 1. The remaining air in the lung on the surgical side cannot be effectively discharged, which affects the exposure of the surgical field; 2. The particularity of the opening of the right upper lung is not fully considered. After the third airbag is inflated, it is likely to block the opening of the right upper lung, so it cannot be given Effectively ventilate the right upper lung or expel residual air from the right upper lung;

However, there are two problems: 1. The particularity of the opening of the right upper lung is not fully considered, and the bronchial part is not suitable for the right lung, and cannot effectively ventilate the right upper lung or discharge the residual air of the right upper lung; 2. Only double lung ventilation and bronchial side In the single-lung ventilation mode, the left and right lungs cannot be ventilated separately, and if the main bronchus on the side where the patient's bronchi is inserted is thin, it may affect the ventilation effect of both lungs
