OXGRD - Tox Gard II Gas Monitor
The large quantity of helium required to maintain an MRI units operating temperature creates a critical safety concern. A helium leak can cause an oxygen-deficient atmosphere that can place the patient at risk. At times, MRI patients are sedated and are unable to signal any potential problem to the MRI operator. In addition, early detection of oxygen deficiency caused by a helium leak can offer protection to the MRI unit itself by signaling a shutdown event. Our Oxygen Monitor, outfitted for MRI rooms, is a uniquely qualified, economical solution. It offers fast, reliable protection from the hazards of oxygen deficiency caused by helium coolant leaks. The Oxygen Monitor incorporates a sample draw pump system that uses no metal components near or inside the actual MRI room, eliminating RF interference from the MRI system. The Oxygen Monitor is mounted in the operator’s office for almost instantaneous notification of a leak via the local audible alarm and flashing LED display. The Oxygen Monitor delivers extremely quiet operation via the dampened mount sample draw system minimizing background noise in the operator’s office.
