Abstract: An inline vaporizer disposed in a carrier gas line vaporizes a fluid and adds such vaporized fluid to a carrier gas that flows within the carrier gas line. The vaporizer includes a reservoir or wick that transfers a fluid to a vaporizing element that is adjacent to the reservoir or wick. The vaporizer releases a vapor into the carrier gas line so that the carrier gas flows past the vaporizer to form a vapor and carrier gas mixture.

Abstract: A multi-use, hand held, single patient oscillatory positive expiratory pressure respiratory therapy device which is easily assembled and disassembled for cleaning, and which is not position dependent during therapy, but operable through a wide range of device orientation.

Abstract: An oscillatory positive expiratory pressure respiratory therapy device which may be incorporated into the expiratory limb of a ventilator circuit. Accordingly, this device allows a patient on a ventilator to be subjected to positive expiratory pressure (PEP) therapy combined with airway oscillation and intermittent air flow acceleration while allowing the oscillatory PEP respiratory therapy treatment to be bypassed without interrupting the integrity of the ventilating circuit once the device has been installed in the ventilator circuit. In this manner, all expiratory air in the ventilator circuit is accounted for, the expiratory air volume may be accurately monitored and the ventilator circuit does not have to be broken for insertion or removal of the device.

Abstract: An enhanced PEP therapy device which provides a variable frequency and variable magnitude positive expiratory pressure by utilizing a nonlinear orifice for adjusting and maintaining a desired positive expiratory pressure oscillation in accordance with a predetermined pressure range of a patient's expiratory air.

Abstract: An improved maximum expiratory pressure device and cough simulator including a flow tube having an integral mouthpiece at a patient input end, and a hinged door at an opposite or discharge end for sealing off the flow tube. The hinged door is held closed by a releasable trigger operable by the patient to release the door after pressure build up to simulate a cough. A foldable pressure monitoring port is provided to connect the maximum expiratory pressure device to a pressure gauge, if desired, for monitoring the expiratory pressure developed within the flow tube.

Abstract: An improved continuous positive airway pressure therapy device including a ring orifice through which compressed air or oxygen is introduced to effectively amplify the air flow to the patient by drawing ambient air into the device inlet for maintaining a continuous positive pressure of a patient's lungs during all portions of the breathing cycle.

Abstract: 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. The GRC also includes a coaching lamp to facilitate the patient's maintaining the desired flow rate of inspiratory air for a predetermined time period. The GRC is operational in one mode 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 of successful exercises previously completed. The operation of the GRC is controlled by a microcontroller which controls the operation of the GRC and the electrical circuit connected thereto is designed to minimize the power requirements of the components when the GRC is placed in the retain and recall mode of operation.

Abstract: A cloud chamber for use with a source of pressurized medication in a MDI system wherein the cloud chamber has a unique one-way inspiratory air and one-way expiratory air valving system which utilizes the same valve body to provide both functions through utilization of different parts of the same valve body for performing the different and mutually exclusive functions. The present invention also provides for the storage of the pressurized medication container within the cloud chamber so that the medication can be conveniently and safely stored when the device in not in use.

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.
