| 20090216097 | Oxygen Sensor for Internal Monitoring of Tissue Oxygen in Vivo - Provided is a durable oxygen sensitive probe of sufficient strength to withstand direct tissue pressures in vivo, the probe comprising a sensor chamber within a biocompatible, gas-permeable membrane containing an oxygen sensitive analyte solution producing oxygen quenchable phosphorescence when excited. Further provided is a tissue oxygen detection and measurement system comprising the probe, and methods for use of the probe and the system to directly, rapidly and accurately measure tissue oxygen levels in a patient without reliance on blood vessels or fluid protection of the probe. | 08-27-2009 |
| 20130211217 | ENDOSCOPE SYSTEM, PROCESSOR DEVICE THEREOF, AND IMAGE PRODUCING METHOD - First and second white light is generated by excitations of phosphors with first and second laser beams having center wavelengths of 473 nm and 445 nm, respectively. The first and second white light is applied, in respective frames, sequentially to a region of interest in a subject. A color image sensor images the region of interest in the each frame. Based on a shift amount, calculated from green signals of first and second frames, between images, an image of a blue signal of the first frame is moved to be aligned with an image of a green signal and an image of a red signal of the second frame. After the alignment, an oxygen saturation image representing an oxygen saturation level of hemoglobin in blood is produced from the blue signal of the first frame and green and red signals of the second frame, and displayed on a display. | 08-15-2013 |
| 20130324815 | CONTINUOUS MEASUREMENT OF TOTAL HEMOGLOBIN - The present application relates to continuous measurement of total hemoglobin (tHb) in whole blood. In one embodiment, different wavelengths are used for normalization of the spectral intensity and calculation of the total hemoglobin. In particular, for normalization, a first wavelength is used wherein the wavelength is substantially insensitive to changes in levels of hemoglobin and oxygen saturation. For calculation of the total hemoglobin, a second wavelength is used. The second wavelength is sensitive to changes in levels of hemoglobin, but substantially insensitive to changes in levels of oxygen saturation. In another embodiment, a continuous measurement can be made using two wavelengths that are both sensitive to oxygen saturation, but they both are equally sensitive. In other words, the normalized intensities associated with the two wavelengths change equal amounts with equal changes in oxygen saturation levels. | 12-05-2013 |
| 20150073241 | MEDICAL DEVICE MANAGEMENT SYSTEM - The present disclosure provides systems and methods for calibrating medical devices and processing physiological measurements using a medical device management system. As an example, the medical device can be a handheld glucometer configured for invasive testing and non-invasive testing of physiological parameters of a patient. | 03-12-2015 |
| 20150327777 | TISSUE MONITORING APPARATUS AND SYSTEM - A tissue monitoring device for selecting, administering or adjusting a treatment based on information obtained by monitoring the tissue. The device includes a substrate for applying to the tissue, for example, a human or an animal external, or internal tissue, including vascular tissue; a light source supported by the substrate, the light source emitting light of a first frequency for directing the emitted light onto a surface of the tissue; a photodetector carried by the substrate spaced from the light source for detecting scattered light, wherein the scattered light is the emitted light scattered by the tissue; and a controller in communication with the photodetector and the light source. | 11-19-2015 |

| 20160058349 | LIGHT SOURCE DEVICE FOR ENDOSCOPE AND ENDOSCOPE SYSTEM - A band limiter comprises an optical filter, which has first and second filter sections, and a filter moving mechanism for moving the optical filter. The first filter section reduces intensity of blue light, which is emitted from a B-LED, in a wavelength range of greater than or equal to a peak wavelength of the blue light to generate first blue light. The second filter section reduces intensity of the blue light in a wavelength range of less than or equal to the peak wavelength of the blue light to generate second blue light. A light source controller places the first filter section in a light path of the blue light in a normal mode to generate the first blue light, and places the second filter section in the light path of the blue light in an oxygen saturation mode to generate the second blue light. | 03-03-2016 |
| 20160374602 | ENDOSCOPE SYSTEM, PROCESSOR APPARATUS FOR ENDOSCOPE SYSTEM, AND METHOD FOR OPERATING ENDOSCOPE SYSTEM - In the special observation mode, second illumination light including different-absorption-wavelength light that has different absorption coefficients for oxygenated hemoglobin and reduced hemoglobin is emitted, a turn-off state is thereafter initiated, and signal reading is performed for some of a plurality of pixel rows in accordance with a skip read method. Subsequently, first illumination light, which is normal light, is emitted, a turn-off state is thereafter initiated, and signal reading is performed for all of the pixel rows in a column direction in accordance with a pixel addition read method. An image processor generates an oxygen saturation image on the basis of a second image capture signal read in accordance with the skip read method and a first image capture signal read in accordance with the pixel addition read method, and generates a normal observation image on the basis of the first image capture signal. | 12-29-2016 |
