摘要：An improved incentive spirometer adapted to introduce a flow of oxygen acrossthe inlet for inspiratory air so that the oxygen may be drawn thereinto without requiringany change in the calibration of the device or the monitoring of the patient's usage. Thedevice also features an integral information display receptacle in the base for storage ofoperational instructions. A portion of the base is transparent to that the informationcontained 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 ofthe incentive spirometer while using the device. The spirometer structure can be utilizedfor different patient groupings by changing a venturi plate to present a flow restrictingorifice designed to accommodate the respiratory therapy and exercise needs for theparticular patient grouping. Individual devices can be readily adjusted for desired resultsby selectively opening or closing tuning ports built into the device.
