Title: THORAX DRAINAGE DEVICE
Abstract:
A thorax drainage device for aspirating fluids from a pleural cavity of a patient by means of vacuum comprises a fluid collecting container (3) for collecting the aspirated fluids and a drainage tube (4) for connecting the fluid collecting container (3) to the pleural cavity (P) of the patient. The fluid collecting container (3) can be connected to a vacuum source (1) in order to generate a vacuum in the fluid collecting container (3). The thorax drainage device has an adjustable mechanism (5) for attenuating pressure differences during the patient's breathing, wherein this mechanism (5) can be adjusted independently of a suction power of the vacuum source (1). This device makes it possible to expand the lungs in stages without any risk of injury and thus prepares the lungs for the end of drainage.
