The garments are connected to these two 12-way connectors, which are push-
tandpolarisedtopreventincorrectorientationoftheconnectors.Thefollowing
pump/garment connections are possible:
• If two garments are used (either two arm garments, two leg
garments, or one arm/leg garment and one garment insert), one will
be connected to the upper connector and the other connected to the
lower connector. The two connections are interchangeable - both
 garmentswillinateatthesametimeandtothesamepressure.
• If only one garment is used, it must be connected to the upper
 connectorandtherubbercovermustbesecurelyttedtothelower
connector (folded as shown).
All garments (arm garments, leg garments and garment inserts) have multiple

Waveinationfromchamber1tochamber12.
2. ALymphAssistcycleiscomprisedofthefollowingsequenceofinations/
deations,startingatchamber12,then11,10,etc.,downtochamber1:
• Thereare5pulseswherethechamberisinatedand
 deated.ThesearereferredtoasLymphAssistpulses.
• Thisisfollowedbyasingle“partial”-peristalticWaveinationof
part of the garment - between the next chamber and chamber 12.
For example, at chamber 5, the 5 LymphAssist pulses are followed by a
partial-peristalticWaveinationfromchamber6tochamber12.
