System and Method for Monitoring Anesthetic Agent Fill Level
First Claim
1. A system for monitoring anesthetic agent fill level in vaporizer reservoir, the system comprising:
- a camera configured to capture an image containing a sight glass on the vaporizer reservoir;
a display;
a processor;
an agent level module executable on the processor to;
locate a sight glass portion within the image;
locate an agent level edge within the sight glass portion of the image;
locate a minimum reference point and a maximum reference point within the image;
calculate fill percentage based on a position of the agent level edge relative to the minimum reference point and the maximum reference point;
access a known volume of the vaporizer reservoir;
calculate a remaining agent information based on the fill percentage and the known volume of the vaporizer reservoir; and
display the remaining agent information on the display.

Abstract
A system for monitoring anesthetic agents fill level in a vaporizer reservoir includes a camera configured to capture an image containing a sight glass on the vapor reservoir, just like, a processor, and an agent level module. The agent level module is executable to locate a sight glass portion within the image, an agent level edge within the sight glass portion, and minimum and maximum reference points within the image. A fill percentage is calculated based on a position of the agent level edge relative to the minimum and maximum reference points, and the remaining agent information is calculated based on the fill percentage and the known volume of the vaporizer reservoir.

11. A method for monitoring anesthetic agent fill level in a vaporizer reservoir, the method comprising:
-
receiving an image of the vaporizer reservoir, the vaporizer reservoir having a known volume for containing liquid anesthetic agent; using machine vision software; locating a sight glass portion within the image; locating a minimum reference point and a maximum reference point within the image; locating an agent level edge within the sight glass portion of the image; calculating a fill percentage based on a position of the agent level edge relative to the minimum reference point and the maximum reference point; calculating a remaining agent information based on the fill percentage; and display the remaining agent information. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
