Abstract

Disclosed is a system and method for monitoring, diagnosing, and treating certain medical conditions, such as asthma, gastroesophageal reflux or laryngopharyngeal reflux. The system includes a mask apparatus or sensor module 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.

Claims

1. A system for monitoring a medical condition comprising:

a film

an apparatus that condenses a sample of an individual'"'"'s breath on said film;

a sensor in close proximity to said film, said sensor positioned such that it contacts said condensed sample of the individual'"'"'s breath when the condensed sample is present;

a processing receiver; and

said sensor in real-time communication with said receiver.

2. The system as recited in claim 1, wherein said apparatus is a general mask or another device for directing the patients'"'"' breath towards said film.

3. The system as recited in claim 1, wherein said sensor is designed to monitor pH.

4. The system as recited in claim 1, wherein said medical condition is a respiratory condition, such as asthma, gastro-esophageal reflux or laryngo-pharyngeal reflux.

5. The system as recited in claim 1, wherein said communication is accomplished by a plurality of wires.

6. The system as recited in claim 1, wherein said communication is accomplished by a wireless means.

7. The system as recited in claim 1, wherein said apparatus has a means to continuously circulate and replace the sample of liquefied breath with a fresh sample of liquefied condensed breath.

8. The system as recited in claim 1, wherein said apparatus has a means to monitor the condensate temperature on said film.

9. A system for monitoring and diagnosing a medical condition comprising:

a film

an apparatus that condenses a sample of an individual'"'"'s breath on said film;

a sensor in close proximity to said film, said sensor positioned such that it contacts said condensed sample of the individual'"'"'s breath when the condensed sample is present;

a processing receiver;

said sensor in real-time communication with said receiver; and

said processing receiver processing said information for determining various diagnoses.

10. The system as recited in claim 9, wherein said apparatus is a general mask or another mask-less device for directing the patient'"'"'s breath in close proximity to said sensor.

11. The system as recited in claim 9, wherein said medical condition is a respiratory condition.

12. The system as recited in claim 9, wherein said communication is accomplished by a plurality of wires.

13. The system as recited in claim 9, wherein said communication is accomplished by a wireless means.

14. The system as recited in claim 9, wherein said sensor is designed to monitor pH.

15. The system as recited in claim 9, wherein said apparatus has a means to continuously circulate and replace the sample of liquefied breath with a fresh sample of liquefied condensed breath.

16. The system as recited in claim 9, wherein said apparatus has a means to monitor the condensate temperature on said film.

17. A system for monitoring, diagnosing, and treating a medical condition:

a film;

an apparatus that condenses a sample of an individual'"'"'s breath on a film comprising;

a sensor in close proximity to said film, said sensor positioned such that it contacts said condensed sample of the individual'"'"'s breath when the condensed sample is present;

a processing receiver;

said sensor in a first real-time communication with said receiver;

said processing receiver processing said information for determining various diagnoses and treatments; and

said processing receiver in a second communication with at least one treatment device to administer at least one therapeutic dose.

18. The system as recited in claim 17, wherein said apparatus is a general mask or another mask-less device for directing the patient'"'"'s breath in close proximity to apparatus.

19. The system as recited in claim 17, wherein said medical condition is a respiratory condition, such as asthma or laryngopharyngeal reflux.

20. The system as recited in claim 17, wherein said first communication is accomplished by a plurality of wires.

21. The system as recited in claim 17, wherein said first communication is accomplished by a wireless means.

22. The system as recited in claim 17, wherein said second communication is accomplished by a plurality of wires.

23. The system as recited in claim 17, wherein said second communication is accomplished by a wireless means.

24. The system as recited in claim 17, wherein said sensor is designed to monitor pH.

25. The system as recited in claim 17, wherein said treatment is a biocompatible agent capable of neutralizing an acidic condition.

26. The system as recited in claim 17, wherein said treatment is sodium bicarbonate.

27. The system as recited in claim 17, further comprising a communication between said processing receiver and a nebulizer/atomizer/humidifier.

28. The system as recited in claim 17, further comprising a third communication between said processing receiver and a continuous positive airway pressure device.

29. An apparatus for monitoring breath chemistry comprising:

a sensor;

a film;

a solid-state cooling means, said cooling means in close proximity with said film;

said cooling means reducing the temperature of said sensor below the dew point of a patient'"'"'s breath such that the patient'"'"'s breath condenses into a liquid that condenses on the film; and

said sensor position such that it is immersed in said liquefied breath on said film when the liquefied breath is present on the film.

30. An apparatus as recited in claim 29, further comprising a means to expel and replenish said collection pool with fresh liquefied patient'"'"'s breath condensate.

31. The system as recited in claim 29, wherein said apparatus has a means to monitor the condensate temperature on said film.
