Thorax drainage system

Abstract

The thorax drainage system consists of reusable containers ( 1, 2 ), drainage line ( 3 ) and connecting lines ( 4, 6 ), and a vacuum pump ( 5 ) with a battery ( 7 ) for operating it, in which system at least the drainage line ( 3 ) is a disposable line and all the components ( 1 - 8 ) can be arranged on a mobile trolley ( 9 ).

1 . A thorax drainage system, characterized by the combination of the following components: 
 a first container ( 1 ) forming a secretion-collecting chamber;    a separate second container ( 2 ) forming a nonreturn valve in the form of an underwater seal;    a drainage line ( 3 ) which can be attached to a patient and leads into the secretion-collecting chamber ( 1 );    a connecting line ( 4 ) between the two containers ( 1 ,  2 );    a vacuum pump ( 5 );    a connecting line ( 6 ) between the vacuum pump ( 5 ) and the container ( 2 ) forming the underwater seal;    a battery ( 7 ) for mains-free operation of the vacuum pump, and    a mobile trolley ( 9 ) for receiving all the system components ( 1 - 8 ),    in which system the two containers ( 1 ,  2 ) can be closed tight with associated covers ( 1 ′,  2 ′) into which the lines ( 3 ,  4 ,  6 ) open, and at least the drainage line ( 3 ) is a disposable line.    
     
     
         2 . The thorax drainage system as claimed in  claim 1 , characterized in that the two separate containers ( 1 ,  2 ) are reusable containers.
