Methods and devices for treating sleep apnea

摘要

A ventilation apparatus for treating sleep apnea is provided. A ventilator controlled by a control system may deliver ventilation gas through a ventilation gas delivery circuit to a ventilation catheter and a distal tip on the ventilation catheter. One or more sensors may detect a breathing cycle and the control system may operate the ventilator in synchrony with the breathing cycle. The distal tip may deliver the ventilation gas superiorly from the transtracheal ventilation catheter towards an upper airway, inferiorly from the transtracheal ventilation catheter towards a lung, or a combination of both. The ventilation catheter may be a transtracheal catheter, a trans-oral catheter or a trans-nasal catheter.

1. A ventilation apparatus for treating sleep apnea, the apparatus comprising:
a ventilator for delivering ventilation gas; a control system for the ventilator; a trans-tracheal ventilation catheter for insertion a trachea; a distal tip on the trans-tracheal ventilation catheter; one or more first sensors, signals from the one or more first sensors measuring actual respiration; one or more second sensors, signals from the one or more second sensors measuring respiration effort; a ventilation gas delivery circuit connecting the ventilator to the trans-tracheal ventilation catheter; wherein a breathing cycle is determined by one or more signals from one or more of the one or more first sensors and the one or more second sensors; and wherein the control system activates the ventilator to deliver an increased volume of ventilation gas synchronized with the breathing cycle when apnea is detected by the one or more first sensors measuring a signal that is abnormally low and the one or more second sensors simultaneously measuring a signal that is not abnormally low.
