MEDICAL DEVICE IMAGING SYSTEMS AND METHODS
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.
1 . A video imaging system, comprising:
a monitor comprising a display screen;
an internal scope comprising a camera that acquires internal images of a patient; and
an environmental camera that acquires environmental images of a patient environment;
wherein the monitor operates to:
receive the internal images from the internal scope and the environmental images from the environmental camera;
receive an internal scope clock time from the internal scope;
determine a first difference between the internal scope clock time and a monitor clock time;
synchronize the internal images and the environmental images based on the first difference; and
combine the synchronized internal and environmental images into a combined video file.
2 . The video imaging system of claim 1 , wherein the combined video file comprises a side-by-side view of the synchronized internal images and environmental images.
3 . The video imaging system of claim 1 , wherein the internal scope is one of a video laryngoscope or an endoscope.
4 . The video imaging system of claim 1 , wherein the monitor operates to use the first difference to synchronize the internal images to the monitor clock time.
5 . The video imaging system of claim 1 , wherein the monitor operates to receive an environmental camera clock time from the environmental camera and determine a second difference between the environmental camera clock time and the monitor clock time.
6 . The video imaging system of claim 5 , wherein the monitor operates to use the second difference to synchronize the environmental images to the monitor clock time.
7 . The video imaging system of claim 1 , wherein the environmental camera is housed in or on the monitor.
8 . The video imaging system of claim 1 , wherein the monitor comprises a portable tablet.
9 . The video imaging system of claim 8 , wherein the environmental camera is coupled to the portable tablet on a side opposite the display screen.
10 . The video imaging system of claim 1 , wherein one or both of the monitor or the environmental camera is coupled to a portable stand.
11 . The video imaging system of claim 1 , wherein the monitor operates to:
identify the internal scope in the environmental images; and
adjust a field of view of the environmental camera to retain the internal scope in the field of view.
12 . A medical device system comprising:
an internal scope that acquires internal images of a patient;
an environmental camera that acquires environmental images;
a monitor that operates to:
receive the internal images from the internal scope;
receive the environmental images from the environmental camera;
determine a first time difference between a monitor clock and an internal scope clock, and a second time difference between the monitor clock and an environmental camera clock;
shift the internal images relative to the environmental images based on the first and second differences, to time-synchronize the internal images and the environmental images to each other; and
generate a video file comprising the time-synchronized internal images and environmental images.
13 . The medical device system of claim 12 , wherein the environmental camera is mounted to a portable stand.
14 . The medical device system of claim 12 , wherein the monitor receives the internal images wirelessly and in real time.
15 . A method, comprising:
receiving, at a monitor, internal images and internal scope clock information from an internal scope;
acquiring, by the monitor, environmental images from a room-facing environmental camera on the monitor, wherein the environmental images are acquired simultaneously with the internal images;
determining a relative time difference between the internal scope clock information and a monitor clock information;
time-synchronizing the internal 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 internal images and environmental images.
16 . The method of claim 15 , wherein the composite video file includes a picture-in-picture or a side-by-side view.
17 . The method of claim 15 , wherein the environmental images are time-stamped with monitor clock information.
18 . The method of claim 15 , further comprising:
receiving, at the monitor, endoscopic images and endoscope clock information from an endoscope;
determining a second relative time difference between the endoscope clock information and the monitor clock information; and
time-synchronizing the endoscopic images with the environmental images based on the second relative time difference,
wherein the combined view in the composite video file further includes the time-synchronized endoscopic images.
19 . The method of claim 15 , further comprising:
receiving patient vital sign data from a patient monitor,
identifying a patient event and an associated time of the patient event in the patient vital sign data; and
overlaying information indicative of the patient event onto the composite video file at the associated time.
20 . The method of claim 15 , further comprising displaying the composite video file on a display screen of the monitor.
