Next generation devices under development
We developed a working prototype of reflective pulse oximeter that enables surgeons to obtain real time feedback on local tissue oxygen saturation (SpO₂) during operative procedures.
This handheld wireless pulse oximeter is suitable for the intra-operative measurement of tissue SpO₂ during bowel surgery. The device adapts principles and technology developed for non-invasive pulse oximetry, and introduces tissue interface, physician’s tool, and signal processing algorithms for intra-operative applications. The handheld device includes local display of SpO₂ levels (<1s refresh) at the contacted tissue, and signals the operative on degraded signal quality/fault. An onboard microcontroller digitizes and processes signals transduced through a control LED array. Signal processing and display parameters were optimized for operating room conditions. A disposable functionally transparent cover provides both device and tissue protection. SpO₂ and pulse signals can be processed on a PC or operating room VI. The incorporations of a pressure sensor to increase accuracy and robustness is explored.
