Title: Innovations by Roger O Herrera
Introduction
Roger O Herrera is an accomplished inventor based in Oakland, CA. He holds five patents that showcase his contributions to medical technology and noninvasive measurement systems. His work focuses on improving patient care through innovative devices.
Latest Patents
One of Herrera's latest patents is a device for capturing thermal spectra from tissue. This device and method enhance the determination of analyte concentrations within living tissue using a noninvasive optical measurement system. In one embodiment, a wearable window is secured to a patient's forearm, isolating a measurement site on the skin for blood glucose level determination. This wearable window effectively replaces a window of the spectrometer, maintaining a consistent measurement site even when the spectrometer is temporarily removed.
Another significant patent is the disposable anti-fog airway adapter. This adapter is designed for use with a mainstream respiratory gas analyzer, providing measurements of a patient's inhaled and exhaled gases. The adapter features windows made of a thin, low heat capacity plastic that quickly equilibrates to the temperature of warm, moist gases. The inside of the windows is coated with an anti-fog surfactant, ensuring that water spreads into a uniform thin layer, thus maintaining signal strength. The design allows for 'instant on' operation without the need for a heater, enhancing its practicality in medical settings.
