Parker Hannifin has created design concepts for valves that can be used in MRI-compatible ventilators. The valves, built to work with a variety of medical fluids and gases, are unaffected by strong magnetic fields and, in turn, do not create any magnetic fields of their own. In addition, the valves can be designed to handle a range of operating characteristics while minimizing total footprint.Parker also seeks to establish partnerships with early adopters of new technology to test and validate design concepts for MRI-compatible valves. Each MRI-compatible ventilator is expected to have three inlet valves and one bleed valve. Any proposed device must be compatible with O2, air and N2O.
