Abstract
An irrigating intraluminal suction inner cannula system for a tracheostomy tube may be a suction-powered system that may be used for suction alone or a combination of rinse and intraluminal suction for tracheostomy tubes in place of conventional catheter-based intraluminal suction. An inner cannula includes chambers, or regions, and holes that facilitate intraluminal suction and cleaning at multiple locations within the tracheostomy tube. It may be applied/actuated by a patient, healthcare worker, caretaker, or via an electronic system either on-demand or on regular or triggered intervals, in either inpatient/hospital or outpatient/ambulatory care setting.
Claims24
An inner cannula for use with a tracheostomy tube, comprising:
- a tube having a diameter for insertion in the tracheostomy tube, a distal end and a proximal end, said tube further comprising:
- a first continuous ridge on an outer surface of the tube, the first continuous ridge having a height that abuts an inner lumen of the tracheostomy tube, wherein the first continuous ridge extends at least along a first length of the tube in a proximal direction, around a circumference of the tube, and along a second length of the tube in the distal direction;
- and
- a second continuous ridge having a height that abuts an inner lumen of the tracheostomy tube, wherein the second continuous ridge extends along the first length of the tube in a proximal direction, around a circumference of the tube, and along the second length of the tube in the distal direction;
- wherein the first continuous ridge and the second continuous ridge divide an airspace surrounding the outer surface into a plurality of separate regions including at least a first region, a second region, and a third region, wherein the third region is in a subglottic region;
- and
- a plurality of holes between an intraluminal space of the tube and an outer surface of the tube in the first and second regions.
A method of cleansing the irrigating intraluminal suction inner cannula system of claim the method comprising:
- attaching the first suction line so that it is in communication with the second region;
- attaching the second suction line so that it is in communication with the third region;
- attaching the actuating device between the first and second suction lines and a vacuum source, said actuating device controllably connecting the first and second suction lines to the vacuum source;
- and
- controlling the actuating device to apply suction to a lumen of the inner cannula through the plurality of holes and the second region, and to apply suction to the subglottic extraluminal space outside the tracheostomy tube through at least one opening of the plurality of openings and the third region.
An inner cannula for use with a fenestrated tracheostomy tube, comprising:
- a tube having a diameter for insertion in the tracheostomy tube, a distal end and a proximal end, said tube further comprising:
- a plurality of holes between an intraluminal space of the tube and an outer surface of the tube, and a continuous ridge on the outer surface of the tube, the continuous ridge having a height that abuts an inner lumen of the tracheostomy tube, wherein the continuous ridge extends at least along a first length of the tube in a proximal direction, around a circumference of the tube, and along a second length of the tube in the distal direction, the continuous ridge dividing an airspace surrounding the outer surface into a plurality of separate regions including at least a first region and a second region;
- a raised area having a height that abuts an inner lumen of the tracheostomy tube in the region of a fenestration of the tracheostomy tube.
