Ballooned ventilation tube cleaning device
A cleaning device, system and method for use with an ETT or tracheostomy ventilation tube 60 , a ventilator machine 900 , a source(s) 602 of fluid (for example, pressurized or unpressurized) and a source(s) of suctioning 603 is disclosed. In some embodiments, the cleaning device is useful for cleaning an inner surface of the ventilation tube 60 and/or for preventing or hindering the accumulation of biofilm thereon. In some embodiments, it is possible to clean biofilm or any other material on the inner surface 201 by delivering fluid into an interior of the ventilation tube, wiping the tube interior with a width-expanded wiping element (e.g. an inflated balloon) by longitudinal motion of the wiping element, and suctioning material out of the ventilation tube ventilation tube.
1. A wiping device for cleaning an inner surface of a ventilation tube in a closed ventilation system where air is mechanically forced into the ventilation tube by an external ventilator, comprising:
a ventilation tube connector assembly,
an elongate flexible main body having a suction lumen and an inflation lumen,
an inflatable balloon mounted to the elongate flexible main body at or near a distal end thereof, the inflatable balloon being sealed and expandable by fluid through the inflation lumen so that a balloon wall is brought into contact with the ventilation tube inner surface when the main body is inserted inside the ventilation tube,
one or more suction orifices on the main body in fluid communication with the suction lumen,
a pliable and impermeable sleeve around at least a portion of the main body,
an input module assembly connected to a proximal end of the main body, the pliable and impermeable sleeve being connected at a distal end to the ventilation tube connector assembly, and at a proximal end to the input module assembly,
the input module assembly having:
(i) a fluid source for inflation of the inflatable balloon, the fluid source comprising a gas delivered from a pressurized reservoir to the inflation lumen, wherein the fluid source is located within the input module assembly,
(ii) a suction port connectable to a suction source, and
(iii) a switching assembly to manually regulate delivery of the gas from the fluid source in the input module assembly to the inflatable balloon and to regulate suction between the suction port and the suction lumen, wherein the switching assembly comprises a single or common switch which regulates both delivery of gas from the fluid source to the inflatable balloon and suction through the suction lumen.
2. The wiping device of claim 1 , wherein the switching assembly comprises:
(ii) a first switch to regulate delivery of gas from the fluid source to the inflatable balloon, and
(iii) a second switch to regulate suction between the suction port and the suction lumen.
3. The wiping device of claim 2 , wherein the first switch and second switch can be simultaneously controlled.
4. The wiping device of claim 2 , wherein the first switch is biased to an off position such there is no gas delivery for inflation of the inflatable balloon.
5. The wiping device of claim 2 , wherein the second switch is biased to an off position such there is no suction through the suction lumen.
6. The wiping device of claim 2 ,
wherein the first switch is biased to an off position such there is no gas delivery for inflation of the inflatable balloon, and
wherein the second switch is biased to an off position such there is no suction through the suction lumen.
7. The wiping device of claim 6 , wherein the first switch and second switch can be simultaneously controlled.
