A pneumatic system consists of an inflatable/deflatable article, for example,
a
compression garment (21) connected to a pump (20) by connectors (12
and 11), respectively. The connector (12) attached to the garment (21)
carries an RFID transponder (30) and a corresponding radio circuit (31)
is located within the pump (20). In use, the transponder (30) transmits
and receives information to and from the pump radio circuit (31). The information
exchanged is used by the pump control system to activate the pump and to operate
the pump to provide the particular operating parameters for that garment, for example,
pressure, inflation/deflation cycle, duration of treatment, etc.
