Title: Innovations of Josef K Tan in Medical Technology
Introduction
Josef K Tan is a notable inventor based in Tampa, FL (US), recognized for his contributions to medical technology. He holds a total of 3 patents, showcasing his innovative spirit and dedication to improving healthcare solutions.
Latest Patents
One of his latest inventions is the Epidural Oxygen Sensor, which is designed to measure the oxygen saturation of blood flow within the skull. This sensor features a photodetector and a pair of light-emitting diodes that are surface-mounted near the end of a flexible printed wiring. The device is hermetically sealed with a rubber or polymeric coating that includes an optical window over the photodetector and light-emitting diodes. The sensor is inserted through a burr hole drilled in the skull and slides between the skull and the dura of the brain. The light-emitting diodes illuminate the blood within the dura and brain, and the reflected light is captured by the photodetector, which converts it into electrical signals. These signals are then processed by a pulse oximeter to provide an indication of blood saturation. In a second embodiment, the photodetector and light-emitting diodes are mounted at the end of a core of compressible foam that extends from a hollow bone screw. As the screw is inserted into the burr hole, the foam compresses to maintain optical contact with the dura, ensuring accurate readings.
