  • Patent number: 11697036
    Abstract: An unpowered respiratory protective headset for personal protective equipment and personal protective bodysuits with an unpowered respiratory protective headset, the unpowered respiratory protective headset having a respiratory mask having a flexible mask body having an interface section and defining a mask air inlet and a mask air outlet, an inhalation valve in the mask air inlet and an exhalation valve in the mask air outlet, and a hood having a hood body and a transparent face shield attached to the hood body. The hood has an air inlet and an air outlet and the air inlet, the mask air inlet, the mask air outlet and the air outlet are configured relative to each other to direct air flow across an inner surface of the transparent face shield to prevent or reduce fogging of the transparent face shield during inhalation and exhalation by a subject.

  • Publication number: 20230210353
    Abstract: Fluorescent imaging systems for performing an endoscopic procedure, such as a retrograde cholangiopancreatography (ERCP) procedure may include a first light source for emitting light in the visible spectrum, or light in the near infrared (NIR) spectrum, or both. A light source bandpass filter may block the emitted light in the visible spectrum, or in the NIR spectrum, or both. A first sensor may be capable of detecting the light in the visible spectrum, or the light in the NIR spectrum, or both. A sensor bandpass filter may block the detected light in the visible spectrum, or in the NIR spectrum, or both. The first or a second light source, or the first or a second sensor, or combinations thereof, may be removably disposed on a duodenoscope.

  • Publication number: 20150073516
    Abstract: The present invention provides a low-cost, low-power therapeutic hypothermia device for use in developing nations. The device includes a first and second receptacle separated by a space filled with a porous material such as sand. A cooling chemical can also be added to the porous material in order to speed cooling. Water is added to the porous material and a neonate is placed into the device for therapeutic hypothermia treatment. The neonate is monitored carefully using temperature sensors and a feedback system integrated into the device. Cooling can be modulated and/or warming commenced by adding Styrofoam blocks to raise the neonate off the surface of the device.

  • Patent number: 8626271
    Abstract: A system for examining an area of a patient's anatomy that comprises a probe capable of fluorescing, and a scanning beam assembly that scans the probe with a beam of excitation radiation and detects the probe's fluorescence. The scanning beam assembly including a radiation source capable of emitting one or more wavelengths of radiation that are capable of exciting the probe and causing the probe to fluoresce, a scanning device that directs the radiation onto a field-of-view to create a scan of the field-of-view, a detector to detect radiation returned from the field-of-view, and a controller to convert the detected radiation into a displayable fluorescence image.

  • Patent number: 5612540
    Abstract: A method for detecting tissue abnormality, particularly precancerous cervical tissue, through fluorescence spectroscopy is disclosed. In vitro fluorescence measurements over a variety of different fluorescence spectra are used to screen tissue samples. Using a principal component analysis (PCA), it is possible to discriminate between normal and dysplastic tissues with relatively low false-positive and false-negative results.
