Sleep apnea ball valve device with bleed for exhaling
View Patent ↗A sleep apnea device with bleed for exhaling including a peripheral wall formed with an interior through passage formed with a proximally facing seat, bleed passages in the wall bypassing the seat and a ball to close against the seat.
1. A sleep apnea device for insertion in a patient's nasal vestibule and comprising:
a wall forming an elongated housing for fitting in the nasal vestibule, having distal and proximal ends and formed with a through, unobstructed flow passage of a predetermined diameter leading from an inlet for flow of air and an interior, proximally facing valve seat integral with the wall;
a ball having a diameter smaller than the predetermined diameter for seating on the seat; and
the wall including more than two open ended bleed passages, having a diameter smaller than the predetermined diameter, leading from an inlet proximal to the seat to an outlet distal of the seat for flow of air to past the ball; whereby, when the sleep apnea device is inserted in the nasal vestibule upon the patient inhaling, inhaled flow in the flow passage will flow past the ball and upon the patient exhaling the ball will be carried into sealing engagement with the seat to block flow in the through passage and provide for air flow through the more than two bleed passages formed in the wall;
wherein the wall is formed with the more than two bleed passages spaced equidistant thereabout bypasing the seat.
2. A sleep apnea device as set forth in claim 1 wherein:
the elongated housing includes a body forming a barrel defining the through passage.
3. A sleep apnea device as set forth in claim 1 wherein:
the wall is formed with a conical through passage converging distally to a reduced diameter of 0.225 inches.
4. The sleep apnea device of claim 1 wherein:
each of the two or more bleed passages a diameter of 0.20 inches.
5. The sleep apnea device of claim 1 wherein:
the wall includes three bleed passages.
6. The sleep apnea device of claim 1 wherein:
the ball has a diameter of 0.250 inches.
7. The sleep apnea device of claim 1 wherein:
the wall is configured with the through passage formed with the inlet having a diameter of 0.225 inches.
8. The sleep apnea device of claim 1 wherein:
the wall is formed with the through passage having a cylindrical inlet and the ratio of the diameter of the bleed passage to the diameter of the cylindrical inlet is 0.089.
9. The sleep apnea device of claim 1 where:
the wall is configured to define the through passage with a cylindrical inlet and wherein the two or more bleed passages are formed with combined diameters of a diametrical length having a ratio with the diameter of the through passage of 0.267.
10. A nasal insert for treating sleep disorders comprising:
an elongated tubular housing for insertion in a patient's nasal passage and including a peripheral wall constructed to form a through, unobstructed flow passage for inhalation of air;
the peripheral wall formed with a proximally facing seat disposed in the passage;
the peripheral wall further formed with more than two longitudinal bleed passages bypassing the seat;
a ball held captive in the passage to be carried by flow of the patient's breath upon exhaling to engage the seat and seal against flow of exhaled air through the flow passage while allowing flow through the bleed passages and to, upon inhaling, be lifted off the seat;
wherein the wall is formed with the more than two bleed Passages spaced equidistant thereabout bypassing the seat.
11. The nasal insert of claim 10 wherein:
the wall is formed with three bleed passages spaced equidistant thereabout bypassing the seat.
12. The nasal insert of claim 10 wherein:
the peripheral wall forms a tubular shell, the shell being one piece.
