  • Flow based incentive spirometer
    Patent number: 6656129
    Abstract: An improved flow based incentive spirometer operable through a range of user set flow rates and being adapted to receive a supplemental flow of Oxygen without requiring any change in the calibration of the device or effecting the patient's monitoring of usage. In this manner the spirometer may be utilized by a range of patients having quite distinct therapy needs. 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.
