    • 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.
    • 一种改进的激励肺活量计,其适于在入口处引入吸入空气的氧气流,使得氧气可以被吸入,而不需要对装置的校准进行任何改变或监测患者的使用。 该设备还具有基座中的整体信息显示插座,用于存储操作指令。 基座的一部分对于容纳在存储容器中的信息在装置使用期间可由患者观看是透明的,从而允许患者观察诸如用于正确使用激励肺活量计的说明书,同时使用 设备。 肺活量计结构可用于不同的患者分组,通过改变文丘里板以呈现设计成适应呼吸治疗和特定患者分组的运动需要的流动限制孔。 通过选择性地打开或关闭内置于设备中的调谐端口,可以容易地调整各个设备的期望结果。
