Intensive Care Air Fluidized Therapy Bed
The strangest radiator / heat exchanger that we manufactured was for an intensive care hospital bed. The bed resembled a large old Victorian bath manufactured in fibreglass. The structure was filled with polystyrene balls with a cloth mattress on top of them. Air was fed up through the balls and mattress to stop bed sours on patients that could not be regularly turned. Unfortunately if the bed was in a sunny area of the ward, the patients ended up bathed in hot air and oven cooked. We took measurements and produced a slim copper and brass chiller unit. Our heat exchanger was fitted into the air intake of the bed and was fed with chilled water. This alleviated the overheating problems that had been encountered.
