Hemanext

Hemanext is a medical technology company developing oxygen-controlled blood storage systems to improve the quality and efficacy of red blood cell transfusions. Its flagship product, Hemanext ONE, is an FDA-cleared processing and storage system that removes oxygen from donated red blood cell units and maintains a low-oxygen environment throughout 42-day refrigerated storage. By minimizing oxidative damage—known as storage lesions—Hemanext ONE preserves red cell membrane integrity, deformability, metabolic function, and oxygen-delivery capacity. The technology addresses a long-standing problem in transfusion medicine: that stored RBCs progressively lose viability, particularly for patients requiring chronic transfusions or emergency trauma care. Hemanext is headquartered in Lexington, Massachusetts, with manufacturing operations in Avon, MA, and has received CMS reimbursement coding recognition for its oxygen-controlled RBC units.
