Apheresis or dialysis procedure underway in a Varna clinic

The image depicts a medical procedure, likely apheresis or dialysis, being performed in a clinical setting. A person, seen from the shoulder down, is seated with their arm extended, connected to a sophisticated medical machine. The machine is white, with a prominent touchscreen display at the top, labeled "TRIMA ACCEL." Various tubes, valves, and a blood-filled chamber are visible on the machine, indicating active blood processing. The person is wearing a light green, ribbed short-sleeved shirt. A white paper sheet is visible behind the person's head, draped over a medical chair. The room appears to be a clean, sterile environment with white walls and tiled flooring. The machine has a sticker with the logo "E" and text in Greek, possibly indicating the manufacturer or service provider. The context suggests this is a healthcare facility, potentially a hospital or specialized clinic. Without further information or visible landmarks, the specific location in Varna, Bulgaria, cannot be definitively identified from the image alone.
