Abstract:
1. A tracheostomy aspiration device for preventing aspirated substance from going inside a lung of a patient and further assisting phonation, the tracheostomy aspiration device comprising: an outer tube having an inner end, an outer end, and a wall extending from the inner end to the outer end, such that the inner end and the outer end are adapted to be placed inside and outside a trachea of the patient respectively, when in use; an inner tube having an inner end, an outer end, and a wall extending from the inner end to the outer end, such that the outer end is adapted to be placed outside the trachea of the patient and receive air from an outside environment, and the inner end is adapted to be placed inside the trachea of the patient to direct the air inside the lung of the patient, wherein the inner tube is disposed inside the outer tube, such that a gap is left in between the inner tube and the outer tube; an inner tube opening in the wall of the inner tube to allow the air to travel from the inner tube to the gap while the patient is exhaling; an outer tube opening in the wall of the outer tube to allow the air to escape from the gap to the trachea of the patient; a valve disposed on the outer tube opening, allowing the air to escape out from the gap to the trachea of the patient while the patient is exhaling, further the valve is adapted to close by gravity while the patient is inhaling and prevent the aspirated substance to go inside the lung from the outer tube opening; and a inflatable cuff disposed around the inner end of the outer tube to create a barrier for the aspirated substance from going inside the lung of the patient and further accumulates the aspirated substance on the inflatable cuff, wherein when the inner tube is fully inserted into the outer tube, a central axis of the inner tube opening is offset from a central axis of the outer tube opening such that the outer tube opening is located more proximally to the inner ends of the inner and outer tubes than the inner tube opening.
