SH100 nuclear magnetic ventilator. Designed and manufactured with non-magnetic materials for military submarine. Pneumatic pneumatic drive, pure mechanical design, ultra-high reliability. It is easy to operate and can solve the problem that the conventional ventilator cannot be used in the nuclear magnetic environment and relies on manual ventilation. Reduce the labor burden of medical staff, reduce the probability of human error, and eliminate the health hazards of long-term exposure of medical staff to strong magnetic and high noise environment. Emergency patients or postoperative convalescent patients can be transferred to MRI room to ensure full respiratory maintenance. Optional no-magnetic trolley or no-magnetic backpack configuration. Trolley configuration meets the needs of in-hospital transport to mri examination room, and backpack configuration is mainly for emergency transport to MRI examination room.
