Medical Devices and Medical Equipment Design IsoTour™ Patient Support Surface by Stryker Medical IsoTour™ was designed using a combination of structural gel, multiple foam compositions and inflatable bladders to help reduce the risk of a patient acquiring a pressure injury while helping to reduce the effort it takes to reposition a patient. The patented gel technology and gel caps help to reduce the Tissue Interface Pressure (TIP). The new gel support surface can be converted into a powered product by connecting an external pump, thereby providing enhanced micro-climate management and turn assist for at-risk patients.
