The Bilirubin Phototherapy Blanket ecosystem spans upstream component sourcing, midstream manufacturing and system integration, and downstream distribution to clinical end users. Raw material and component suppliers provide medical‑grade LEDs, polymer films, and filter media that define phototherapy efficacy. OEM manufacturers assemble the blankets, embedding light arrays and control circuitry, while technology providers add firmware, safety algorithms, and connectivity for patient monitoring. System integrators adapt the devices to neonatal care protocols and align them with regulatory standards. Distributors and channel partners handle logistics, inventory, and market penetration, delivering the finished product to hospitals, neonatal intensive care units, and pediatric clinics where the blankets are employed to treat neonatal jaundice.
