A portable intermittent pneumatic compression pump decrease the risk of developing deep vein thrombosis by using air displacement to promote blood circulation within the lower limb of the body. The device has a sleeve 3 for a lower leg that may have multiple chambers 2 that have air pumped sequentially 5 from the lower chamber to the upper chamber. A pressure sensitive one way valve 4 situated on the last, uppermost, chamber to be inflated ensures that a pre-determined pressure is not exceeded. The rotary pump 1 that supplies the air to the chambers may be located at the bottom of the sleeve. The pump 1 may be battery operated. The sleeve may come in a variety of sizes. |
