Deep vein thrombosis (DVT) is the formation of blood clots in the deep veins, typically in the lower extremities. Clots often form during periods of immobility, particularly following major orthopedic surgery. Key risk factors include sluggish blood flow, vein wall damage, and hypercoagulability. Once formed, most clots extend into the major deep veins rather than remaining isolated. If not diagnosed and treated promptly, many patients develop post-thrombotic syndrome, which can affect quality of life for years. In some cases, clots can travel to the lungs, causing a pulmonary embolism — a potentially life-threatening complication.

Pneumatic compression therapy is clinically proven to prevent DVT and is widely adopted across clinical disciplines worldwide. By applying pressure exceeding atmospheric levels to targeted areas, the system helps push venous blood and lymphatic fluid from high-pressure peripheral zones toward lower-pressure central vessels, promoting the return of pooled blood and lymphatic fluid toward the heart. This significantly increases venous output and blood flow velocity, effectively preventing DVT and reducing edema. By sequentially inflating and deflating multi-chamber sleeves, the system creates circulatory pressure on the limbs and surrounding tissues — accelerating venous blood flow, promoting clearance of venous pooling, generating pulsatile blood flow to improve microcirculation, and enhancing fibrinolytic activity to effectively prevent DVT. At Flybear, safety comes first. While we strive for clinical effectiveness and quality, we place equal — if not greater — emphasis on patient safety. Even pneumatic compression devices carry risks if used improperly; prolonged high-pressure operation can increase the risk of tissue and microcirculation damage. In certain clinical modes, Flybear's built-in safety control system — consistent with international best practices — automatically manages pressure levels, interval timing, and compression patterns, greatly reducing the risk of operator error and safeguarding patient well-being.
