Pleura cavity negative pressure ventilation breathing machine and using method thereof

Abstract

The invention provides a pleural cavity negative pressure ventilation breathing machine and a using method thereof. A breathing machine comprises a breathing machine main body; and the breathing machine main body is provided with a ventilation opening, the ventilation opening is connected with a ventilation piece, and the ventilation piece can extend into a pleural cavity through a thoracocentesis wound so that the breathing machine main body can change the pressure in the pleural cavity. The using method comprises the following steps of S1, puncturing the pleural cavity by using a thoracocentesis assembly; S2, extending an end part of the ventilation piece into the pleural cavity from the puncture wound; and S3, starting the breathing machine main body, injecting air into the ventilation piece and exhausting the air from the ventilation piece by the breathing machine main body so as to change the pressure in the pleural cavity, and achieving then collapse and expansion of lungs. By utilizing the leakproofness of the pleural cavity of a human body, the ventilation piece is arranged in the pleural cavity by adopting a minimally invasive puncture technology, the pressure in the pleural cavity is changed through the breathing machine main body to enable the lungs to be collapsed and expanded, general anesthesia and tracheal intubation are not needed, the pressure generated on lung tissue is reduced, and the probability of complications can be reduced.

Description

technical field [0001] The invention relates to the technical field of ventilators, in particular to a pleural cavity negative pressure ventilator and a method for using the pleural cavity negative pressure ventilator. Background technique [0002] In the prior art, a positive pressure ventilation machine is usually used to assist or replace a patient's breathing. [0003] Positive pressure ventilation machines include non-invasive positive pressure ventilation machines and invasive positive pressure ventilation machines. Among them, the non-invasive positive pressure ventilation machine can only play a limited role in assisting breathing, and is only used for some patients with mild or moderate respiratory dysfunction. For patients with moderate-severe respiratory dysfunction, such as patients with impaired respiratory center (such as some strokes and patients with traumatic brain injury, etc.), patients with severe respiratory muscle weakness (such as myasthenia gravis an...

Problems solved by technology

Endotracheal intubation will not only cause direct damage to the patient's larynx and trachea so that the patient's laryngeal edema and poor sputum discharge will cause lung infection, etc., but will also significantly increase the risk of aerosol transmission of COVID-19 and the risk of infection caused by the use of anesthetics. risks (including risks of anesthesia drugs, deep vein thrombosis due to general anesthesia, pneumonitis, pressure sores, etc.), and will restrict patients' daily life; Significant mechanical stress that can cause lung injury (such as barotrauma and pneumothorax) that can exacerbate underlying lung disease that can lead to respiratory failure
