This treatment reduces debilitating pain, swelling, ulceration, and risk of dermatological impact, infection, and amputation. Compression pumps of various kinds are in wide use in hospitals, clinics, patient homes, and elsewhere for treating acute and chronic fluid accumulation disorders. Complies with physician-prescribed treatment pressures. ## Device Story Electromechanical pneumatic device; consists of compressor, precision timer, regulator, and gauge. Operates by inflating a sleeve appliance fitted over patient's extremity to apply physician-prescribed pressure. Used in hospitals, clinics, and home settings. Provides single-pressure compression therapy to improve fluid circulation; reduces pain, swelling, and risk of complications like ulceration or infection. Simple design intended for mild cases of lymphedema compared to sequential systems. ## Clinical Evidence No clinical data. Bench testing performed comparing on-board gauge readings to a calibrated Hg manometer to verify cell pressure accuracy and cycle timing. ## Technological Characteristics Electromechanical pneumatic compression pump. Dimensions: 8"W x 6.75"H x 5.5"D; weight < 13 lbs. Factory-preset maximum pressure < 101 mm Hg. System includes pump and sleeve appliance. ## Regulatory Identification A compressible limb sleeve is a device that is used to prevent pooling of blood in a limb by inflating periodically a sleeve around the limb. ## Predicate Devices - Huntleigh Flowtron AC200/2 ([K874688](/device/K874688.md)) - Jobst Extremity Pump System 7000 ([K882683](/device/K882683.md)) - Talley MicroSystem/Talley ([K914775](/device/K914775.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
