Sphere Medical is a medical device company that has developed a technological platform for the development of advanced physiological monitoring devices, including apparatuses for use in hospital’s intensive care unit. The company uses a combination of proprietary biomaterials with micro-analyzer platforms that contain sensor chips to measure different physiological properties and signal processing chips that contain the control electronics for the medical device. The company’s monitoring systems can be used for intermittent or continuous monitoring of blood, or other body fluids, and for parameters such as glucose, pH, gasses, and electrolytes. Accurately monitoring key physiological parameters, such as blood pH and glucose levels, is a critical component for gauging a patient’s health and ability to carry out basic life functions, particularly in the intensive care unit.
