Abstract
Systems and methods are provided for detecting unacceptable accelerations by an anesthetic vaporizer, such as due to drops and mishandling. In one embodiment, a method for an anesthetic vaporizer comprises determining a quantitative acceleration of the anesthetic vaporizer based on acceleration vectors measured by an accelerometer coupled within the anesthetic vaporizer, and outputting an alert responsive to the quantitative acceleration exceeding an acceleration threshold. In this way, drop-related degradation may be identified in a timely fashion.
Claims20
A method for an anesthetic vaporizer, comprising:
- determining a quantitative acceleration of the anesthetic vaporizer based on acceleration vectors measured by an accelerometer coupled within the anesthetic vaporizer;
- and
- outputting an alert responsive to the quantitative acceleration exceeding an acceleration threshold.
A system for an anesthetic vaporizer, comprising:
- an accelerometer positioned within an external housing of the anesthetic vaporizer;
- and
- a controller storing executable instructions in non-transitory memory that, when executed, cause the controller to:
- receive measurements from the accelerometer recorded while the anesthetic vaporizer is powered off;
- resolve a quantitative acceleration from the received measurements;
- determine an orientation of the anesthetic vaporizer from the received measurements;
- and
- output a first type of alert in response to the quantitative acceleration exceeding an acceleration threshold.
A method for detecting a fall of an anesthetic vaporizer, comprising:
- upon start-up of the anesthetic vaporizer, receiving acceleration measurements recorded by an accelerometer coupled within the anesthetic vaporizer while the anesthetic vaporizer is powered off;
- determining a magnitude and direction of an acceleration vector from the acceleration measurements;
- selecting an acceleration threshold based on the direction of the acceleration vector;
- and
- outputting a drop alert in response to the magnitude of the acceleration vector exceeding the acceleration threshold.
