Single-lung breathing protector

Abstract

The invention relates to a single-lung breathing protector, which comprises a positioning protecting tube. A protecting sleeve sac is arranged at one end of the positioning protecting tube, and is communicated with a protecting sleeve sac inflating tube which is used for inflating the protecting sleeve sac, the protecting sleeve sac inflating tube is fixed on the outer wall of the positioning protecting tube, and the other end, which is correspondingly connected with the protecting sleeve sac, of the protecting sleeve sac inflating tube extends out from the outer wall of the positioning protecting tube. As the positioning protecting tube is isolated from the protecting sleeve sac, an isolating effect of a double-cavity bronchial catheter can be improved, single-lung breathing resistance is low while pressure is also low, a good lung protecting effect is realized, the positioning protecting tube can realize shaping and positioning via a shaping tube core, requirements to materials of the positioning protecting tube are reduced, service cost is lowered, the application range of a single-cavity bronchial catheter or the double-cavity bronchial catheter is expanded, and graduations are arranged on the positioning protecting tube, so that insertion positioning precision of the positioning protecting tube is high. The single-lung breathing protector is convenient in use and compact in structure and ensures safety and reliability of single-lung breathing surgery.

Description

technical field [0001] The invention relates to a protector, in particular to a one-lung ventilation protector, which belongs to the technical field of medical devices. Background technique [0002] One-lung ventilation refers to the method or method in which only one lung (non-operated side) is used to ventilate patients undergoing thoracic surgery through an endotracheal tube. At present, the scope of application of one-lung ventilation through anesthesia has been greatly expanded. In addition to being used for patients with a lot of pulmonary secretions, it is also often used in operations such as esophagus, lung lobe, whole lung, and thoracoscopic surgery to facilitate surgical operations and reduce surgical side effects. Lung damage to prevent cross-infection between the two lungs.

AI Technical Summary

Problems solved by technology

[0003] The current means of one-lung ventilation are double-lumen bronchial catheters and bronchial occluders, both of which have obvious defects, which seriously affect clinical use

In some cases, when performing one-lung ventilation, the inner diameter of the ventilation tube is too narrow, resulting in high airway pressure, which is likely to cause lung injury, especially during the implementation of long-term one-lung ventilation.

Some endotracheal tube lumens are too hard and the diameter of the double lumen is too thick, which may easily cause glottic injury during intubation

For some positioning, a fiberoptic bronchoscope must be used at the same time. Two medical devices can move freely in the lumen of the endotracheal tube at the same time, requiring a relatively thick lumen diameter, which affects the safety of the corresponding operation.
