Gradian UAM | Universal Anaesthesia Machine
The Gradian UAM (Universal Anaesthesia Machine) is the world’s first CE-marked anesthesia machine designed to work without electricity and medical oxygen. With a built-in oxygen concentrator, standard connections for other oxygen sources, and key features on battery backup, the UAM uses a combination of continuous-flow and draw-over technologies to deliver general anesthesia safely in any setting.
KEY FEATURES & BENEFITS
- Built-in Oxygen Concentrator:Generates medical-grade oxygen from room air (without external oxygen source)
- Draw-over Mode: Enables anesthesia delivery without electricity or oxygen source
- UAM Ventilator: Automatically breathes for patient (with 6 hours of battery power)
- Multiple Oxygen Ports: Inputs for nearly any additional oxygen source (cylinders, pipelines, and concentrators)
- Vital Signs Monitor: Measures blood pressure, temperature, pulse oximetry, and ECG (with 6 hours of battery power)
- Vaporizer Options: Accepts 3 anesthetic agents (halothane, isoflurane, and sevoflurane)
- Generic Components: Allows for local, low-cost sourcing of replacement parts and consumables
Safe, Reliable Anesthesia
Our first product – the Universal Anaesthesia Machine® (UAM) – is a CE-certified device designed to function without electricity or compressed oxygen.
Ventilator
Fully automatic, electrically-driven ventilator with 6-hour rechargeable battery backup; no oxygen needed
Oxygen Monitor
Touch-screen oxygen monitor that displays inspired oxygen content and lasts up to 10 hours on battery backup
Low-Resistance Vaporizer
Low-resistance vaporizer that accurately delivers a calibrated flow of halothane, isoflurane or sevoflurane with or without compressed gas
Bellows
Manual bellows that ensures safe, assisted respiration for adults and children without requiring a high-pressure gas source; provides backup means of IPPV to the ventilator
Integrated Oxygen Concentrator
Built-in oxygen concentrator that produces up to 10 liters per minute of up to 95% oxygen; room air cleaned with a dual filtration system
