Abstract

Systems for delivery of therapeutic agents and related methods are disclosed. A sensing system is configured to detect a chemical in the vicinity of a patient and transmit a signal to a controller upon detection. A controller is configured to release a therapeutic agent which is transported to the site of interest. The controller communicates with an electronic medical records database, an alarm and a nurse call system.

Claims

1. A system comprising:

a sensor configured to generate a signal in response to a chemical;

a therapeutic agent repository; and

a control system configured to receive said signal from said sensor and control flow of a therapeutic agent from said therapeutic agent repository to a site.

2. The system of claim 1, wherein said sensor is a metal oxide semi-conductor type sensor.

3. The system of claim 1, wherein said sensor is an organic semi-conducting polymer type sensor.

4. The system of claim 1, wherein said sensor is a surface acoustic wave type sensor.

5. The system of claim 1, wherein said sensor is a protein based sensor.

6. The system of claim 1, wherein said therapeutic agent repository is integrated in a mattress topper.

7. The system of claim 1, wherein said control system is configured to communicate with an electronic medical record database.

8. The system of claim 1, wherein said control system is configured to communicate with a nurse call system.

9. The system of claim 1, wherein said control system is configured to communicate with an alarm.

10. The system of claim 1, wherein said control system is configured to communicate with an air filtration system.

11. The system of claim 1, wherein said control system comprises a control interface.

12. The system of claim 1, further comprising a display configured to communicate with said control system.

13. The system of claim 12, further comprising a person support apparatus, said display configured to shown at least one indication about said person support apparatus.

14. The system of claim 1, said control system comprising a processor to analyze said signal and control said therapeutic agent repository.

15. The system of claim 1, wherein said control system comprises a first processor configured to analyze said signal and a second processor to control said therapeutic agent repository, said first sensor configured to communicate with said second sensor.

16. The system of claim 15, wherein said first sensor and said second sensor communicate wirelessly.

17. The system of claim 15, wherein said first processor is configured to control said second processor to deliver therapeutic agent from said therapeutic agent repository to said site if said signal indicates concentration of said chemical exceeds a predetermined threshold.

18. The system of claim 1, wherein said therapeutic agent comprises at least one vasodilator.

19. The system of claim 1 wherein said therapeutic agent is delivered via a patch.

20. The system of claim 1 wherein said therapeutic agent is delivered via a cuff.

21. A system comprising:

a person support apparatus;

a sensor configured to generate a signal response to at least one chemical in secretion from a person supported by said person support apparatus

a therapeutic agent reservoir; and

a control system configured to receive said signal, said control system configured to control flow of a therapeutic agent from said therapeutic agent reservoir to site of said secretion.

22. The system of claim 21, wherein said control system is configured to compare said signal with an earlier signal supplied by said sensor and alert a caregiver if said comparison indicates a change greater than a predetermined threshold.

23. The system of claim 21, further comprising a fluid transport system configured to transport fluid away from a person supported by said person support apparatus.

24. The system of claim 21, wherein said control system further comprises a memory configured to store signals supplied by said sensor for a predetermined time.

25. A method comprising:

sensing a chemical in a secretion;

determining whether concentration of said chemical is greater than a predetermined threshold; and

releasing a therapeutic agent to a site of said secretion if concentration of said chemical is greater than said predetermined threshold.

26. The method of claim 25, further comprising determining if said chemical is an indicator of presence of a chemical.

27. A therapeutic device comprising:

means for generating a signal in response to a chemical in a secretion; and

means for controlling flow of a therapeutic agent to a site of said secretion based on said signal.

28. A system comprising:

a sensor configured to generate a signal in response to a chemical in a secretion;

a therapeutic agent repository; and

a control system configured to receive said signal from said sensor and control flow of a therapeutic agent from said therapeutic agent repository to a site of said secretion.
