  • Publication number: 20250235645
    Abstract: An example nasal airway tube includes a tubular body having a distal end and a proximal end. A surface at the distal end including an opening. The tubular body having an overall curvature with a radius of curvature defined relative to a longitudinal axis of the tube. An X-axis is defined by the longitudinal axis of the tube, and a Y-axis extends perpendicularly from the longitudinal axis and has a positive direction defined outwardly relative to the radius of curvature. At least a portion of the opening faces outwardly relative to the radius of curvature. A vector normal to a plane defined by the opening includes a positive Y-coordinate.

  • Publication number: 20220378598
    Abstract: A nasopharyngeal airway device includes an elongate body having a distal end and a proximal end. The elongate body has an outer surface defining one or more open channels extending along the elongate body. The nasopharyngeal airway device includes a securement component securely coupled to the elongate body. The securement component is configured to secure the nasopharyngeal airway device within a nostril of an individual.

  • Patent number: 10395370
    Abstract: A method and a wearable apparatus for disease diagnosis are provided. The method is applied to the wearable apparatus with an image capturing unit and a display unit. In this method, a plurality of input images in a field of view of the wearable apparatus are captured by using the image capturing unit, wherein each of the input images contains an array of pixels. The variations of the pixel values in a time domain are analyzed. The pixel variations within a specific frequency range are magnified and the magnified pixel variations are added onto the original ones to generate an output image. The output image is overlapped with a current image in the field of view of the wearable apparatus and displayed on the display unit.
