It is a completely portable intermittent pneumatic compression device that has a battery lasting up to 24 hours. The compression therapy mimics the body’s natural muscle contractions to increase venous blood flow to the body’s lower extremities. The Devon24R is the only portable DVT prevention device that can be removed from the sleeves. The pump is removable with single-patient use replacement sleeves.
