  • Publication number: 20230113642
    Abstract: Systems and methods of optical transcutaneous oxygenation monitoring. The oxygenation monitor comprises a photoluminescent oxygen-sensitive probe, a photon source positioned to direct photons at the probe, a photodetector positioned to detect light emitted from the probe when the photon source directs photons at the probe, a controller in electrical communication with the photon source and the photodetector, the controller being configured to execute a program stored in the controller to calculate a level of oxygen adjacent the probe from an electrical signal received from the photodetector. The photon source, the photodetector, and the controller are disposed in or on a support structure.

  • Publication number: 20220257797
    Abstract: Compounds, systems, and methods are provided for the design and assembly of a non-invasive, analyte sensing dressing. The dressing can be therapeutic. The dressing includes a sensor and a matrix. The sensor is capable of detecting analytes such as molecular oxygen, carbon dioxide, nitric oxides, dissolved analytes in plasma, and hydrogen ions. The matrix is at least partially permeable to the analyte. The device emits a detectable signal when the sensor is excited in the presence of the analyte. In one version of the dressing, the sensor includes a meso-unsubstituted metallated porphyrin that is sensitive towards oxygen. The metallated porphyrin can be excited when illuminated at a first wavelength, followed by emission of phosphorescence at a second wavelength whose intensity can be used as an indicator for oxygen concentration.
