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. The air bag has multiple pockets. The pockets are isolated from each other and connected to the air connectors respectively. Thus, each pocket can compress a part of the human limb independently. With the independent pockets, the compression device may compress a specified part of the human limb rather than the whole wrapped human limb. Moreover, with the pockets independently compressing and relaxing, the wrapped human limb may experience a massage, which helps the wrapped human limb to relax and recover.
