A closed suction system module is provided. In one embodiment, the closed suction system module includes a coupling member configured to couple to a suction port of a multi-port manifold or endotracheal tube adapter (e.g., dual-port or tri-port adapter). In one embodiment, the closed suction system module includes a suction catheter configured to clean the interior surfaces of body-inserted tubes or artificial airways (alone or in addition to suctioning natural airways or portions of the respiratory tract or other body lumens). The suction catheter may include a cleaning portion at a distal portion of the suction catheter (e.g., near the distal end or tip of the suction catheter). In some embodiments, the cleaning portion includes at least one expandable cleaning member (e.g., balloon, sleeve, wiper).

1. An endotracheal tube and airway cleaning system, comprising: an endotracheal tube coupling adapter comprising a ventilator port, a suction port and a distal port, said distal port configured to directly or indirectly couple to an endotracheal tube; anda closed suction system module comprising a coupling member, a flexible enclosure and a suction catheter,wherein the coupling member of the closed suction system module is configured to couple to the suction port of the endotracheal tube coupling adapter,wherein the flexible enclosure extends proximally to the coupling member of the closed suction system module and is configured, during use, to prevent exposure of the suction catheter to an outside environment;a cleaning portion located at or near a distal end of the suction catheter;wherein the cleaning portion comprises at least one cleaning member, said at least one cleaning member configured to be radially expanded; anda control unit located along a proximal end of the suction catheter,wherein the control unit is configured to selectively expand and retract the at least one cleaning member and control suction through the suction catheter, andwherein, upon expansion of the at least one cleaning member, at least a portion of the at least one cleaning member is configured to contact an interior surface of an endotracheal tube such that when the suction catheter is withdrawn from the endotracheal tube, biofilm collected on the interior surface is removed by the at least one cleaning member into a cleaning chamber of the closed suction system module,wherein the control unit comprises at least one activation member and at least one stop positioned at a location within the control unit such that the at least one activation member is configured to contact the at least one stop after the at least one activation member has been depressed a certain distance, wherein the at least one stop prevents further depression of the at least one activation member, and wherein the at least one activation member is configured to compress a fluid or gas reservoir in fluid communication with the at least one cleaning member, thereby causing the at least one cleaning member to expand to a volume determined as a result of a position of the at least one stop within the control unit,wherein the at least one activation member is configured to cause simultaneous expansion of the at least one cleaning member and initiation of suction through the suction catheter. 2. The system of claim 1, wherein the at least one cleaning member is pneumatically expandable. 3. The system of claim 2, wherein the at least one cleaning member comprises a balloon. 4. The system of claim 3, wherein the balloon comprises one or more rings or wipers. 5. The system of claim 4, wherein at least a portion of the one or more rings or wipers is smooth. 6. The system of claim 1, wherein the control unit is configured to be operated using a single hand of an operator on the control unit to selectively expand and retract the at least one cleaning member and control suction through the suction catheter. 7. The system of claim 1, wherein the at least one activation member comprises a plunger. 8. The system of claim 1, wherein the at least one activation member comprises two activation members. 9. The system of claim 1, wherein the endotracheal tube coupling adapter comprises a valve configured to facilitate cleaning of the at least one cleaning member within the cleaning chamber while the closed suction system module is coupled to the endotracheal tube coupling adapter. 10. The system of claim 1, wherein the at least one cleaning member comprises a lubricant and/or a bactericide. 11. The system of claim 1, wherein the endotracheal tube coupling adapter comprises a stopcock adapted to cause the endotracheal tube coupling adapter to be switched between a first position in which no fluids may pass through the stopcock and a second position in which fluids are able to pass through the stopcock. 12. A closed suction system module, comprising: a coupling member configured to couple to a suction port of a multi-port manifold;a suction catheter configured to clean interior surfaces of body-inserted tubes and/or suction body lumens, the suction catheter comprising: a cleaning portion at a distal portion of the suction catheter, the cleaning portion comprising at least one expandable cleaning member;a control unit located along a proximal end of the suction catheter; andat least one activation member configured to cause simultaneous expansion of the at least one expandable cleaning member and initiation of suction through the suction catheter, wherein the control unit comprises at least one stop positioned at a location within the control unit such that the at least one activation member is configured to contact the at least one stop after the at least one activation member has been depressed to a certain distance, wherein the at least one stop prevents further depression of the at least one activation member, wherein the at least one activation member is configured to compress a fluid or gas reservoir in fluid communication with the at least one expandable cleaning member, thereby causing the at least one expandable cleaning member to expand to a volume determined as a result of a position of the at least one stop within the control unit, andwherein, upon expansion of the at least one expandable cleaning member, at least a portion of the at least one expandable cleaning member is configured to contact an interior surface of a body-inserted tube such that, when the suction catheter is withdrawn from the body-inserted tube, biofilm collected on the interior surface is removed by the at least one expandable cleaning member into a cleaning chamber of the closed suction system module; anda flexible sheath configured to prevent exposure of a portion of the suction catheter outside of a body-inserted tube to an external environment. 13. The closed suction system module of claim 12, wherein the at least one expandable cleaning member is pneumatically expandable. 14. The closed suction system module of claim 12, wherein the at least one activation member comprises a plunger that is configured to compress the fluid or gas reservoir in fluid communication with the at least one expandable cleaning member through an inflation channel within the suction catheter, thereby causing the at least one expandable cleaning member to pneumatically expand. 15. The closed suction system module of claim 12, wherein the suction catheter comprises at least a first suction port positioned proximal of the at least one expandable cleaning member. 16. The closed suction system module of claim 12, wherein the at least one expandable cleaning member comprises an inflatable balloon. 17. The closed suction system module of claim 12, wherein the at least one expandable cleaning member comprises one or more rings or wipers. 18. The closed suction system module of claim 17, wherein a leading edge of the one or more rings or wipers comprises a squared or substantially squared edge. 19. The closed suction system module of claim 17, wherein at least a portion of the one or more rings or wipers is smooth. 20. The closed suction system module of claim 12, wherein the at least one expandable cleaning member comprises a lubricant and/or a bactericide. 21. The closed suction system module of claim 12, wherein the suction catheter comprises at least a first suction port distal to the cleaning portion and at least a second suction port proximal to the cleaning portion, and wherein the first and second suction ports are adapted to be dynamically controlled to allow suction distal and/or proximal to the cleaning portion.
