CONCORD, Mass.--(BUSINESS WIRE)--Luminous Medical Inc. has used SolidWorks Corporation’s 3D CAD and analysis software to design and refine a potentially life-saving glucose measurement system for hospital patients. Any intensive care, operating room, or intermediate care unit requires tight control of patients’ blood sugar levels. A nurse testing a patient by drawing blood once or twice per hour consumes some two hours of nursing time per day, placing a strain on staffing and affecting health-care costs.
