A person wearing a blue glove and a bracelet is seen placing a small, white, rectangular object with a barcode and other markings into a slot inside a medical device. The device has a compartment that is open, revealing four black holders, which already contain similar objects with barcodes, and a row of four dark brown bottles with lids. The device has a gray cable and a pen-like instrument with a blue light attached to it. The environment consists of tiled flooring.
