Abstract

An improved incentive spirometer adapted to introduce a flow of oxygen across the inlet for inspiratory air so that the oxygen may be drawn thereinto without requiring any change in the calibration of the device or the monitoring of the patient's usage. The device also features an integral information display receptacle in the base for storage of operational instructions. A portion of the base is transparent to that the information contained in the storage receptacle can be viewed by a patient while the device is in use, thereby permitting a patient to observe such things as the instructions for proper use of the incentive spirometer while using the device. The spirometer structure can be utilized for different patient groupings by changing a venturi plate to present a flow restricting orifice designed to accommodate the respiratory therapy and exercise needs for the particular patient grouping. Individual devices can be readily adjusted for desired results by selectively opening or closing tuning ports built into the device.
