This Application is a continuation of U.S. patent application Ser. No. 12/274,083, filed Nov. 19, 2008, U.S. Pat. No. 8,931,478, entitled, “PATIENT INTERFACE ASSEMBLY FOR RESPIRATORY THERAPY,” which claims the benefit of U.S. Provisional Patent Application No. 60/988,977, filed on Nov. 19, 2007, entitled, “RESPIRATORY THERAPY SYSTEM WITH ELECTROMECHANICAL DRIVER,” the disclosures of which are incorporated herein by reference in its entirety.
FIG. 1 is a schematic illustration of a respiratory therapy system.
FIGS. 2-14 are schematic illustrations of other respiratory therapy systems.
FIGS. 15 and 16 are illustrations of a first embodiment of a patient interface device.
With particular reference to FIG. 16, venturi assembly 330 forms an entrainment region 342, a throat region 344 and an expansion region 346 for combining air from inlet port 304 and entrainment port 306 and delivering combined air to a lumen 350 fluidly coupled to outlet connector port 308. In the embodiment illustrated; entrainment region 342 defines an inlet opening 352 to inlet port 304 and entrainment port 306. Throat region 344 defines a tapered, converging portion that routes flow within venturi assembly 330. Expansion region 346 defines a tapered, diverging portion that increases in diameter from the throat region 344 toward lumen 350, terminating at an outlet opening 356. Although other configurations for venture assembly 330 can be used, in the venturi assembly 330 illustrated in FIGS. 15 and 16, air flow is routed through a converging portion to a diverging portion to lumen 350.
1. A method for delivering respiratory therapy to a patient, comprising:
delivering combined air from the jet pump to a nebulizer; introducing medication into the combined air using the nebulizer;
forming a seal between the jet pump and an inner sealing surface of the housing to close a flow path between an exhalation port and an outlet port of the housing;
progressively occluding a cut-out through the housing, between the exhalation port and the inner sealing surface, as the jet pump moves toward the inner sealing surface; and
2. The method of claim 1, comprising exhausting air flow received from the patient through the exhalation port.
combining the pressurized gas flow with the ambient air in an entrainment region of the jet pump;
forcing the combined air through a throat region of the jet pump; and
delivering the combined air to an expansion region of the jet pump.
4. The method of claim 1, wherein a spring biases the jet pump with respect to the housing in a direction toward the inlet port.
5. The method of claim 1, wherein as the jet pump moves away from the outlet port, a flow path is created between the exhalation port and the outlet port.
6. The method of claim 1, wherein the housing includes a nebulizer port fluidly coupling the nebulizer to the housing.
7. The method of claim 1, wherein the cut-out is defined through the housing and tapers toward the outlet port.
8. A method for delivering respiratory therapy to a patient, comprising:
combining the pressurized gas flow with the ambient air using a jet pump slideably disposed within the housing;
delivering combined air from the jet pump to an outlet port in the housing; and
forming a seal between an exhalation port and the outlet port when the jet pump engages against an inner sealing surface of the housing, wherein forming the seal progressively occludes a cut-out through the housing, between the exhalation port and the inner sealing surface of the housing, as the jet pump moves toward the inner sealing surface outlet port.
9. The method of claim 8, wherein the cut-out through the housing is tapered toward the outlet port.
10. The method of claim 8, further comprising exhausting, via the exhalation port, air flow received from the outlet port.
12. The method of claim 8, wherein a spring biases the jet pump with respect to the housing in a direction toward the inlet port.
13. The method of claim 8, wherein as the jet pump moves away from the outlet port, a flow path is created between the exhalation port and the outlet port.
14. The method of claim 8, wherein the housing includes a nebulizer port fluidly coupling a nebulizer to the housing.
15. The method of claim 8, wherein as the jet pump moves away from the outlet port, an orifice of the cut-out is progressively unblocked.
