Device and method for providing power to lighting elements for use as a visual indicator in a medical probe |
摘要 |
A lighting device for use as a visual indicator in a medical probe is provided. The lighting device includes one or more light emitting elements that are used as a visual status indicator for the medical probe, and a driver circuit that receives current from a power source and drives the light emitting elements. The driver circuit includes a current sensor to sense a current flowing through the light emitting elements, and a shut off switch. The shut off switch shuts off the power source current from the light emitting elements based on the sensed current from the current sensor. |
