Acoustic pressure inducers and methods for treatment of obstructive sleep apnea

摘要

Acoustic pressure inducers and methods for treating obstructive sleep apnea are disclosed. In one embodiment, an acoustic pressure inducer includes an actuator housing having an orifice, a tube having a first end and a second end, and a nasal cannula fluidly coupled to the second end of the tube. The first end of the tube is fluidly coupled to the orifice of the actuator housing such that a gap is present between the first end of the tube and the orifice. The nasal cannula is configured to be positioned proximate to nostrils of a user. The acoustic pressure inducer further includes a vibrating element within the actuator housing and a signal generator. The signal generator component is electrically coupled to the vibrating element and configured to provide an electronic signal to the vibrating element to cause the vibrating element to oscillate within the actuator housing and produce an acoustic jet of air that exits the orifice and enters a nasal passageway of the user through the nasal cannula.

1. An acoustic pressure inducer for treatment of obstructive sleep apnea comprising:
an actuator housing comprising an orifice; a tube having a first end and a second end, the first end fluidly coupled to the orifice of the actuator housing, wherein a gap is present between the first end of the tube and the orifice; a nasal cannula fluidly coupled to the second end of the tube, wherein the nasal cannula is configured to be positioned proximate to nostrils of a user; a vibrating element within the actuator housing, wherein the vibrating element and the actuator housing define an acoustic chamber that is fluidly coupled to the orifice; and a signal generator component electrically coupled to the vibrating element and configured to provide an electronic signal to the vibrating element to cause the vibrating element to oscillate within the actuator housing, wherein:
oscillation of the vibrating element produces an acoustic jet of air comprising a train of vortices; andthe acoustic jet of air exits the orifice and enters a nasal passageway of the user through the nasal cannula to prevent respiratory tract occlusion.
