Abstract: The present invention is a system for continuous real-time monitoring of a patient's breath chemistry comprising a plurality of components, including a self-condensing pH sensor distally mounted on a catheter, a pepsin sensor distally mounted on a catheter either separately or in combination with a self-condensing pH sensor, a transmitter with hydration sensing circuitry, and processing receiver/data recorder that can be a smart phone, tablet, TV, watch, wearable device, or custom designed device with wireless capability and utilizing an APP (application) that displays and records the pH and/or pepsin collected data.

Abstract: Disclosed is a system and method for monitoring the breath chemistry of a patient's breath using a specially designed self-condensing sensor module mounted in a mask, nasal cannula, headband with boom apparatus, or similar device for directing the patients' breath towards the self-condensing sensor. Monitoring of a patient's breath pH provided by the miniaturized self-condensing pH sensor provides for real-time monitoring of patient airway pH values. The specially designed self-condensing sensor module incorporates a data transfer means, e.g. direct wiring or by providing a transmitter with an antenna for wireless transferring of the pH data to a processing receiver. The self-condensing pH sensor comprises a multi-tubular design with the outer tubular member housing a silver chloride reference element, an ion conducting path, and an antimony sensor plug isolated in an inner tubular member that is co-linearly or coaxially configured with the outer tubular member.

Abstract: Disclosed is a system and method for monitoring, diagnosing, and treating certain respiratory conditions, such as asthma. The system includes a mask apparatus fitted with a pH sensor and thermocouple, a continuous positive airway pressure (CPAP) device, a processing receiver, and a therapeutic nebulizer/atomizer/humidifier device. The mask apparatus, CPAP device and therapeutic nebulizer/atomizer/humidifier device are connected by a pneumatic means. The pH sensor and the thermocouple are in electrical communication with the processing receiver that controls, through an electronic means, the CPAP device and therapeutic nebulizer/atomizer/humidifier device. The electrical communications can be in the form of a plurality of wires or employ wireless means.

Abstract: The present invention is a system for monitoring a patient's breath chemistry comprising a plurality of components, including a self-condensing pH sensor distally mounted on a catheter, a transmitter with hydration sensing circuitry for the pH sensor, and processing receiver/data recorder. A specially designed self-condensing pH sensor is located on the distal end of a tubular catheter which is designed to be inserted into the patient's airway. Monitoring of a patient's breath pH is accomplished by using the miniaturized self-condensing pH sensor, providing for real-time monitoring of patient airway pH values. The self-condensing pH sensor comprises a multi-tubular design with the catheter tubular member housing a silver chloride reference element, an ion conducting path, and an antimony sensor element isolated within an inner tubular member that is co-linearly or coaxially configured with the outer catheter tubular member.

Abstract: The present invention is a system comprising an illumination means and is mounted on a catheter wherein said illumination is generally located in the distal end of the catheter. Locating the illumination means near the distal end will simplify and facilitate precise placement of a measurement device in close proximity to the desired location. In one example, a catheter with a distally mounted pH sensor benefits from the use of an illumination means in the patient's airway such as in the oropharynx region. The illumination source of the present invention addresses catheter insertion and location using a continuous or flashing light emitting diode (LED) embedded in the distal end of the catheter to provide a visual sighting means for the physician.

Abstract: The present invention pertains to an apparatus for evaluating the signal strength from the pH sensor to determine whether the sensor is hydrated sufficiently to accurately measure pH. This is accomplished by utilizing circuitry that periodically sends a low voltage signal to a suitable pH sensor and then receiving the resulting waveforms which are analyzed by a processing receiver. The electrical connection between a suitable pH sensor and hydration monitoring circuitry is generally hard wired. In one embodiment, a processing receiver is coupled with the hydration monitoring circuitry as a single apparatus. In a second embodiment, the processing receiver can be independent and located remote from the hydration monitoring circuitry. In this embodiment, the hydration monitoring circuitry and the processing receiver are electrically connected using either hard wired techniques or wireless technology. In addition, the processing receiver can include data recording capability.
