Surgical drainage tube system

DETAILED DESCRIPTION It is therefore an object of the present invention to provide an improved wound drainage system wherein an adaptable wound drainage tube is employed with appropriate adaptors as a single lumen or a multi-lumen drainage system.
It is a further object of the present invention to provide an apparatus for cleaning out obstructed drainage lumens of drainage tubes without resorting to manual stripping techniques and which is highly effective.
It is a still further object of the present invention to provide an adaptable multi-lumen drainage tube that may be introduced surgically in the conventional manner and selectively and securely coupled with separate drainage tube adaptors for effecting simple, single lumen drainage and more complex, multi-lumen drainage augmented by irrigation and/or ventilation capabilities.
It is another object of the present invention to provide a drainage lumen clean-out apparatus and method that is simple to use and does not require retraction of the tube.
In accordance with one aspect of the present invention, a wound drainage system is provided which includes an elongated catheter or tube having at least two lumens extending between proximal and distal ends thereof, the lumens terminating in one or more openings at or near the distal end of the tube, wherein the drainage lumen is provided with an opening at the proximal end of the tube and the additional, auxiliary lumen or lumens are obstructed at the proximal end thereof, and wherein the system further includes a set of adaptors for adapting the tube to single lumen and multi-lumen uses.
In this aspect of the invention, each adaptor in the set includes a main drainage lumen with a first drainage lumen connector for connecting with the proximal opening of the drainage lumen and a second drainage lumen connector for making connection with a suitable collection vessel and suction apparatus for applying a suction pressure through the adaptor and to the drainage lumen, and wherein the multi-lumen adaptors further include at least one secondary lumen and lumen connector for making connection with the auxiliary lumen when the obstruction in the proximal end thereof is opened and having a connector adapted to be coupled to secondary drainage facilitating structures, such as anti-bacterial air filters for ventilation or a source of irrigation fluid or the like
