Abstract

Systems, methods, and dressings are presented that involve using a RFID device in a dressing to provide pressure data or other data to a remote base unit. The dressing is an interactive dressing. The reduced pressure in the dressing may be monitored and used to control delivery of reduced pressure. In one instance, the pressure data at each dressing allows a plurality of tissue sites to be monitored and used with as single remote base unit. In another instance, devices and methods for assuring a proper pairing of reduced-pressure dressings and remote base units are also presented. Other systems, methods, and dressings are presented.

Claims

1. A method for treating at least one tissue site with reduced pressure, the method comprising:

disposing a first, wireless, reduced-pressure dressing proximate to a first tissue site, wherein the first, wireless, reduced-pressure dressing comprises;

a distribution manifold for placing adjacent to the tissue site and for providing reduced pressure to the tissue site,

a sealing member covering at least a portion of the distribution manifold,

a first processor,

a RFID antenna coupled to the first processor, and

a first sensor coupled to the first processor, wherein the first sensor comprises a pressure sensor;

providing a remote base unit comprising a RFID reader;

providing reduced pressure to the distribution manifold;

transmitting a first pressure inquiry signal from the RFID reader to the first, wireless, reduced-pressure dressing;

receiving a first pressure message signal from the first, wireless, reduced-pressure dressing in response to the first pressure inquiry signal; and

wherein the first pressure message signal is wirelessly transmitted by the RFID antenna to the remote base unit without requiring any pressure sensing lumens in the reduced-pressure delivery conduit.

2. The method of claim 1, further comprising determining if the first pressure message signal is greater (on an absolute pressure scale) than a target pressure, and if greater than the target pressure, then activating the reduced-pressure source, and if less (on an absolute pressure scale) than the target pressure, then deactivating the reduced-pressure source.

3. The method of claim 1, wherein the method further comprises:

disposing a second, wireless, reduced-pressure dressing adjacent to a second tissue site;

transmitting a second pressure inquiry signal from the RFID reader to the second, wireless, reduced-pressure dressing; and

receiving a second pressure message signal from the second, wireless, reduced-pressure dressing in response to the second pressure inquiry signal.

4. The method of claim 1, further comprising a second sensor coupled to the first processor, wherein the second sensor comprises a temperature sensor.

5. A system for treating at least one tissue site with reduced pressure, the system comprising:

a first, wireless, reduced-pressure dressing for disposing proximate to the tissue site, wherein the first, wireless, reduced-pressure dressing comprises;

11. The system of claim 5, wherein the reduced-pressure source comprises a micropump adjacent to the distribution manifold.

12. The system of claim 5, wherein the first, wireless, reduced-pressure dressing does not include a battery.

13. The system of claim 5, wherein the first, wireless, reduced-pressure dressing is adjacent to a first tissue site, and further comprising a second, wireless, reduced-pressure dressing adjacent to a second tissue site.

14. A wireless, reduced-pressure dressing for treating a tissue site with reduced pressure, the wireless, reduced-pressure dressing comprising:

a distribution manifold for placing adjacent to the tissue site and for providing reduced pressure to the tissue site;
