A medical system for facilitating the removal of body matter including solids, liquids and gases from a body cavity. The system includes mechanical energy applied to the interior surface of a catheter or other type of body drainage conduit to substantially inhibit the adherence of body matter to the catheter, thus minimizing the likelihood of blockage in the catheter. The mechanical energy may be provided by a rotating wire coil, reciprocating wire with collapsible cups or other device to substantially inhibit the adherence of body matter to the catheter and promote flow into a drainage and disposal system |

DETAILED DESCRIPTION Accordingly, the primary objective of the present invention is to provide a system for facilitating the movement of body matter including solids, semi-solids, liquids and gas from a body cavity without impeded flow or blockage as a result of adherence of this body matter to the interior wall surface of the catheter.
This and other objects of the invention are accomplished by providing a mechanical energy source within the interior of one or more body drainage tubes such as a catheter.
The drainage tubes are used in conjunction with suction means for encouraging the movement of body matter from the inlet end of the drainage tube to an outlet end, which is interconnected to a collection chamber for collecting body matter removed from the patient.
The mechanical energy may be provided in numerous forms including, but not limited to, a rotating wire coil, reciprocating collapsible cup(s) or vanes, or a magnetic shuttle-cock which moves as a result of alternating electrical current in the wall of the catheter.
In another aspect of the invention the mechanical energy may be provided to a plurality of catheters inserted in a patient's body while commingling the body solids, liquids and gas into a central drainage/gathering tube.
This is accomplished by providing mechanical energy within the central drainage/gathering tube and transferring that energy with one or more gears or other energy transferring devices to the plurality of catheters.
The bodily fluids, solids and gases are subsequently drained into a fluid collection chamber for safe disposal.
It is another object of the present invention to remove the aforementioned body matter from a body cavity in a manner which reduces vibration and any unnecessary movement of the catheter to increase patient comfort and reduce the likelihood of the catheter becoming detached from the patient's adjoining tissue.
In one aspect of the invention, this may be accomplished by providing mechanical energy to the interior wall surface with a rotating wire or wire coil that is driven either manually with a hand operated type of cranking mechanism or more preferably with a motor driven by electricity, air or other means known in the art
