Systems, methods, and dressings for providing reduced pressure to a tissue site on a patient are presented that involve wirelessly providing power to a reduced-pressure pump. In one instance, a RFID antenna is used to power a reduced-pressure pump that is fluidly coupled by a conduit to a reduced-pressure dressing. In another instance, a reduced-pressure dressing incorporates a micro-pump and a RFID antenna that is used to power the micro-pump. Other systems, methods, and devices are presented.本發明提供用於將減壓提供至一病患上之一組織部位之系統、方法及敷件,該等系統、方法及敷件涉及以無線方式將電力提供至一減壓泵。在一個例項中,使用一RFID天線給藉由一導管流體耦合至一減壓敷件之一減壓泵供電。在另一例項中,一減壓敷件併入有一微型泵及用於給該微型泵供電之一RFID天線。亦提供其他系統、方法及裝置。
