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 mattress on which a person lies;

a sensor configured to generate a signal in response to a chemical that is indicative of a condition of the person;

a therapeutic agent repository containing a therapeutic agent for treating the condition of the person; 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 the person through a portion of the mattress to treat the condition of the person with the therapeutic agent, 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 processor configured to communicate with said second processor.

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, wherein said first processor and said second processor communicate wirelessly.

15. The system of claim 1, 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.

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