Abstract: The present invention provides a leveling platform for an i LA®/external lung device which can be patient adjusted. The platform includes upper and lower planar support members pivotally attached to each other along one side of each member and the opposed side includes an adjustment mechanism for pivoting the top support member with respect to the bottom support members to provide a level adjustment. The top support member includes a retaining mechanism for holding an i LA® ECLS device and level indicators to indicate whether or not the top support member is level. The bottom support member rests on a surface such as a bed or chair to which the platform can be secured. Once the ECLS device is connected to the patient and supported in the ECLS device is mounted on the top surface of the leveling platform and if required, the adjustment mechanism is engaged by the clinician or patient to level the ECLS device.
