摘要：An improved incentive spirometer having a modular goal recording counter(GRC) releasably attached thereto for enabling a patient to view the number of times a
predetermined respiratory therapy inhalation exercise has been properly performed. TheGRC also includes a coaching lamp to facilitate the patient's maintaining the desired flowrate of inspiratory air for a predetermined time period. The GRC is operational in onemode to initiate a count of the number of successful exercise completions beginning with“0”, and in another operational mode to retain and recall the count of the number ofsuccessful exercises previously completed. The operation of the GRC is controlled by amicrocontroller which controls the operation of the GRC and the electrical circuitconnected thereto is designed to minimize the power requirements of the componentswhen the GRC is placed in the retain and recall mode of operation.
