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.
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.
