IsoTour™ Patient Support Surface by Stryker Medical

Home > Winners > #75618


DESIGN DETAILS
DESIGN NAME:
IsoTour™

PRIMARY FUNCTION:
Patient Support Surface

INSPIRATION:
It’s an unfortunate fact: each year, more than 2.5 million people in the United States develop pressure injuries. These wounds bring pain, associated risk for serious infection, and increased healthcare utilization. The average cost of a pressure injury can range from $20,000 - $151,700. Also, 35,000 nurses miss work each year due to musculoskeletal injuries from repositioning patients in beds.

UNIQUE PROPERTIES / PROJECT DESCRIPTION:
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 unique styling of IsoTour™ is focused on highlighting the technical and clinical attributes of the product, leading to a highly effective sale process.

OPERATION / FLOW / INTERACTION:
The IsoTour™ gel design was derived from a custom mathematical model for nonlinear buckling gel. This model was used to determine the height, shape, pitch and wall thickness of the gel to optimize buckling for a wide range of patients. To validate our model, we used nonlinear FEA simulation. The result is a new gel design with 6” tall hexagonal structure, minimal draft angles, and gel caps to increase surface atop the column to minimize TIP. Another gel challenge was the molding process, particularly ejecting a 6” thick component comprised of hot, sticky gel with minimal draft angles and gel caps at one end. The team developed an innovative system of action rods in the tool that pull the gel out of the mold after the injection cycle thereby making it easy to manufacture. In parallel, we worked on our unique and patent-pending offloading turn system. We developed small and narrow bladders that were powerful enough to turn a patient up to 30 degrees per typical clinical protocols. The bladders are positioned under the thigh and shoulder blades creating a void under the sacrum, thereby facilitating the turn of a patient without applying pressure to the sacrum (Offloading).

PROJECT DURATION AND LOCATION:
The project started in November 2015 in Kalamazoo Michigan and finished in December 2018 in Kalamazoo Michigan.

FITS BEST INTO CATEGORY:
Scientific Instruments, Medical Devices and Research Equipment Design

PRODUCTION / REALIZATION TECHNOLOGY:
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. TruTurn feature differs from the current embodiment and has a patented sacral offloading component.

SPECIFICATIONS / TECHNICAL PROPERTIES:
IsoTour Mattress: Overall length 2000 mm or 2140 mm Overall width 902 mm Thickness 241 mm IsoTour Pump: Height 419.1 mm Width 215.9 mm Depth 171.45 mm
