Abstract
A time-synchronized video imaging system includes an environmental camera that acquires environmental images of a patient while a video laryngoscope acquires airway images of the patient. A monitor receives the airway images from the video laryngoscope and the environmental images from the environmental camera. The monitor time-synchronizes the airway images and the environmental images to each other to generate a combined view video file of the time-synchronized airway images and environmental images to permit review of macro or environmental effects on a patient intubation.
Claims20
A video imaging system, comprising:
- a monitor comprising a display screen;
- a video laryngoscope comprising a camera that acquires airway images of a patient;
- and
- an environmental camera that acquires environmental images of a patient environment;
- wherein the monitor operates to:
- receive the airway images from the video laryngoscope and the environmental images from the environmental camera;
- receive a video laryngoscope clock time from the video laryngoscope;
- determine a first difference between the video laryngoscope clock time and a monitor clock time;
- synchronize the airway images and the environmental images based on the first difference;
- and
- combine the synchronized airway and environmental images into a combined video file.
A medical device system comprising:
- a video laryngoscope that acquires airway images of a patient;
- an environmental camera that acquires environmental images;
- a monitor that operates to:
- receive the airway images from the video laryngoscope;
- receive the environmental images from the environmental camera;
- determine a first time difference between a monitor clock and a video laryngoscope clock, and a second time difference between the monitor clock and an environmental camera clock;
- shift the airway images relative to the environmental images based on the first and second differences, to time-synchronize the airway images and the environmental images to each other;
- and
- generate a video file comprising the time-synchronized airway images and environmental images.
A method, comprising:
- receiving, at a monitor, airway images and laryngoscope clock information from a video laryngoscope;
- acquiring, by the monitor, environmental images from a room-facing environmental camera on the monitor, wherein the environmental images are acquired simultaneously with the airway images;
- determining a relative time difference between the laryngoscope clock information and a monitor clock information;
- time-synchronizing the airway images and the environmental images based on the relative time difference;
- and
- generating a composite video file with a combined view of the time-synchronized airway images and environmental images.
