Abstract
An irradiation device includes a fluid treatment chamber configured to receive a biological fluid container, the fluid treatment chamber having opposing first and second sides, at least one light source disposed adjacent at least one of the first and second sides of the fluid treatment chamber, and an overflow reservoir in fluid communication with the fluid treatment chamber to receive fluid leaking from the biological fluid container. The device also includes a non-contact sensor disposed adjacent the overflow reservoir and configured to generate a signal according to leaked fluid in the overflow reservoir, an indicator, and a controller coupled to the at least one light source, the non-contact sensor and the indicator, the controller configured to activate the indicator upon receipt of the signal from the sensor and to deactivate the at least one light source subsequent to receipt of the signal from the sensor.
