Respiratory muscle training device

Abstract

A respirator muscle training device comprises a main unit including at least one adjustable air metering vent, the main unit comprising a stem configured to accept a replaceable mouthpiece; and a replaceable mouthpiece configured to mate with the stem, the replaceable mouthpiece being configured to deliver air flow between the main unit air metering vent and a patient's mouth. The mouthpiece defines at least one supplementary metering channel that predictably modifies a resistance of the respirator muscle training device to user inhalation and/or exhalation through the device. An intermediate component containing sensors and other electronics monitors the flow of air through the training device and provides measured parameters to an external device that can use the measurements in a breathing game.

1 . A respirator muscle training device comprising:
 a main unit including at least one adjustable air metering vent, the main unit comprising a stem configured to accept a replaceable mouthpiece; and   a replaceable mouthpiece configured to mate with the stem, the replaceable mouthpiece being configured to deliver air flow between the main unit air metering vent and a patient's mouth,   wherein the mouthpiece defines at least one supplementary metering channel that predictably modifies a resistance of the respirator muscle training device to user inhalation and/or exhalation through the device.   
     
     
         2 . A respirator muscle training kit comprising:
 a portion including at least one adjustable air metering vent and configured to accept a replaceable mouthpiece; and   a first replaceable mouthpiece configured to connect to the portion, the replaceable mouthpiece being configured to deliver air flow between the metering vent and a patient's mouth, and   a second replaceable mouthpiece configured to connect to the portion, the replaceable mouthpiece being configured to deliver air flow between the metering vent and the patient's mouth, and   wherein the second mouthpiece defines at least one supplementary metering channel that modifies a resistance to user inhalation and/or exhalation through the metering vent.
