Problems solved by technology

Intermittent double-lung ventilation is inconvenient for surgical operation and delays the surgical process
If high-frequency ventilation is used for the affected lung, an additional high-frequency jet ventilator is required, and it is easy to cause CO2 accumulation

Abstract

The invention provides an adjustable lung separating ventilation component. The effects that the air flow of an inspiratory phase is adjustable and the air flow of an expiratory phase is not limited are achieved. The component can be connected to the tail end of the affected side of a double-lumen tube; in the inspiratory phase, the ventilation volume of oxygen inlet through an air inlet passage can be controlled through an adjusting knob; in the expiratory phase, the expiratory air flow is not blocked in an air outlet passage, which is beneficial to CO2 exhaust. Therefore, while appropriate ventilation is conducted on the affected side lung, surgical operation is not influenced, and it is avoided that air stays in the affected side lung; by means of the adjustable lung separating ventilation component, the ventilation way is simplified, single lung ventilation is improved, and negative effects brought by high concentration oxygen uptake are avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an adjustable lung isolation ventilator. Background technique [0002] During lung isolation surgery, in order to facilitate the exposure of the surgical field, one-lung ventilation on the healthy side is generally used. During one-lung ventilation, due to the imbalance of ventilation / blood flow ratio, it is difficult for some patients to maintain blood oxygen saturation during operation. Moreover, a higher inspired oxygen concentration is often required to maintain proper blood oxygen saturation during one-lung ventilation 2 . Long-term high-concentration oxygen inhalation may lead to impairment of pulmonary surfactant synthesis and increase the occurrence of postoperative pulmonary complications. In order to maintain blood oxygen saturation, intermittent bilateral lung ventilation or high-frequency ventilation of the affected lung is sometimes required during the ope...
