<p>A thoracic draining device, comprising, in a monolithic structure, three interconnected contiguous chambers, which are adapted to be placed in partial vacuum by being connected to a source of suction which is capable of creating, within the device, a condition of vacuum which conveys away from the patient the exuded liquids and the air losses, said chambers comprising: a first chamber (100) for collecting the exuded liquids, which is adapted to be connected by means of a tube to the thoracic cavity of a patient, so as to receive said exuded liquids and the air losses that exit from said cavity, a second sealing chamber (200), provided at the bottom with a device for measuring said air losses, a third chamber (300) for adjusting the vacuum that occurs within the two preceding chambers, comprising a column of water (14) through which atmospheric air is made to pass which enters at the bottom formed by a perforated bubbling partition (15) and is conveyed thereat by a duct (16) after entering through a perforated plug (18) in order to be evacuated through a connector (8) which is designed to be connected to the source of suction, at the top of the third chamber (300), in said monolithic structure, a separator (23a, 23b) being provided for the two phases constituted by water and atmospheric air which are mixed in the stream that exits as a consequence of bubbling from the free surface of the water column (14) that is present in said third chamber (300), with consequent fall of the water onto said column (14) and exit of the atmospheric air from said chamber toward the suction source.</p> |
