Breathing auxiliary drainage apparatus and method

Abstract

The invention discloses a breathing auxiliary drainage apparatus and method. The apparatus comprises a drainage pipe, a liquid trap communicating with the drainage pipe, and a negative pressure generator communicating with the liquid trap so as to communicate with the drainage pipe through the liquid trap, wherein a drainage inlet is formed at one end, which is away from the liquid trap, on the drainage pipe, a pressure sensor is formed at the outer wall of the drainage pipe close to the drainage inlet, and the pressure sensor is electrically connected with the negative pressure generator through a transmission line formed in the drainage pipe and the liquid trap. By using the breathing auxiliary drainage apparatus and method, pressure in a thoracic cavity can be detected in real time, the pressure in the thoracic cavity is increased or decreased through combination with the breathing motion of a patient, accumulated gas and accumulated liquid in the thoracic cavity are effectively discharged, the compliance of lung is enhanced, a breathing function is improved, the burden of a cardiopulmonary function of the patient is mitigated, the need for breathing metabolism is met, at the same time, the possibility of endotracheal intubation for assisted ventilation is also reduced, and a series of correlated complications are avoided.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a drainage device and method. Background technique [0002] Closed thoracic drainage device is a routine device after thoracic surgery. It draws out the gas and liquid accumulated in the chest cavity, prevents its reflux, promotes lung recruitment, and prevents mediastinal displacement and lung compression. [0003] The current closed chest drainage device mostly relies on the extrusion of the lungs, the change of intrathoracic pressure and the effect of gravity when the patient breathes to achieve the drainage effect. If necessary, take continuous negative pressure suction. However, the pressure during negative pressure suction cannot change with the change of intrathoracic pressure during breathing, and cannot produce an auxiliary effect on breathing. When the patient exhales, because of the continuous negative pressure, it will have a negative effect on the respiratory function...

AI Technical Summary

Problems solved by technology

However, the pressure during negative pressure suction cannot change with the change of intrathoracic pressure during breathing, and cannot produce an auxiliary effect on breathing. When the patient exhales, because of the continuous negative pressure, it will have a negative effect on the respiratory function. Not conducive to drainage and recovery of lung function
