Abstract: A compression device has a main body and a wrap. The main body has an air pump and a valve assembly. The valve assembly has a manifold, multiple first valves, and multiple air connectors. The manifold connects the air pump and the first valves. The air connectors are connected to the first valves respectively. The wrap is used for wrapping a human limb and has an air bag.

Abstract: A filter assembly employs radially inwardly and outwardly displaced portions of a peripheral roll seam on the cartridge as components of a cartridge compatibility matrix. A base defines an axial entrance to a fixed retainer that is complementary to the compatibility matrix of the cartridge roll seam. Axial slots accommodate the outwardly displaced portions of the roll seam while inward protrusions correspond to the location and inward displacement of the inwardly displaced segments of the roll seam. Incompatible filter cartridges are prevented from axial reception into the base. The number, configuration and location of inwardly and outwardly displaced portions of the roll seam may be varied to provide a variety of unique compatibility matrices.
