These devices typically resemble wearable sleeves for the arms or legs, featuring an interior composed of multiple independent air chambers or elastic materials designed to apply rhythmic compression and release to the limbs according to a preset program. Originally used in the care of bedridden patients, their application has since expanded to fields such as sports rehabilitation and the management of varicose veins; they are now common physical therapy tools in both home and clinical settings.
Compression therapy devices are generally used to improve blood circulation in the limbs, alleviate swelling, or prevent blood clot formation. By using inflatable air chambers to apply pressure, they simulate the muscle contractions that occur during physical activity, thereby facilitating the return flow of blood and lymph fluid. For instance, post-operative bedridden patients use them to prevent deep vein thrombosis in the legs, office workers use them to relieve foot swelling, and individuals with varicose veins use them regularly to reduce vascular pressure. Certain models can also assist burn patients in controlling scar tissue proliferation or help athletes accelerate their post-exercise recovery.
