US 12,708,732 B2 · Method and apparatus for providing percussive ventilation therapy to a patient airway

Abstract

Method and apparatus for providing percussive ventilation therapy to a patient airway preferably includes at least one driver unit configured to provide pressurized, non-pulsate gas. At least one patient interface device preferably has structure configured to (i) receive the pressurized, non-pulsate gas from the at least one driver unit and transform it into a pulsed and pressurized gas, and (ii) supply at least one sub tidal volume of pulsed and pressurized gas to a patient through a patient connection orifice. At least one flexible tube is preferably configured to provide pressurized, non-pulsate gas from the at least one driver unit to the at least one patient interface device. Preferably, at least one portion of the patient interface device is disposable, and another portion may be reusable. Preferably, the invention uses Adaptive Dynamic Subtidal Ventilation technology.

Dependent claims

A patient interface device for delivering percussive gas to a patient, comprising:

an inspiration module having at least one inlet port to receive pressurized gas and an outlet port to deliver the pressurized gas to the patient during inspiratory phase, wherein the inspiration module comprises a hollow inner body and a sliding Venturi valve slidably connected to the inner body, wherein the Venturi valve is configured to slide relative to the inner body;
and
an expiration module comprising a hollow outer body that partially encloses the inner body of the inspiration module and completely encloses the sliding Venturi valve, wherein the expiration module is configured to vent exhalation gas from the patient during expiratory phase and wherein the exhalation module includes a patient connection orifice to deliver the pressurized gas to the patient and to receive the exhalation gas from the patient.

A ventilation system for delivering percussive gas to a patient, comprising:

a ventilator that is configured to supply pressurized gas;
a patient interface device for delivering percussive gas to the patient, comprising:
an inspiration module having at least one inlet port to receive pressurized gas and an outlet port to deliver the pressurized gas to the patient during inspiratory phase, wherein the inspiration module comprises a hollow inner body and a sliding Venturi valve slidably connected to the inner body, wherein the Venturi valve is configured to slide relative to the inner body;
and
an expiration module comprising a hollow outer body that partially encloses the inner body of the inspiration module and completely encloses the sliding Venturi valve, wherein the expiration module is configured to vent exhalation gas from the patient during expiratory phase and wherein the exhalation module includes a patient connection orifice to deliver the pressurized gas to the patient and to receive the exhalation gas from the patient;
and
a tubing system including at least one flexible tube connecting the ventilator to the patient interface device.
