The image shows a medical device, specifically a dialysis machine, which is used for treating patients with kidney failure. The machine has several components including a dialyzer, tubing, and a monitor. The dialyzer is a large, cylindrical device that filters blood to remove waste products and excess fluid. The tubing connects the dialyzer to the patient's veins and arteries, allowing blood to flow through the dialyzer. The monitor displays vital signs and other data related to the patient's condition during the dialysis process.
