When I look at the Flaskwork device I'm reminded of the pumps used on most patients in the hospital to administer IV fluids. Essentially I believe the two pumps in the Flaskwork device are functioning in much the same way. As I understand it, they use two pumps to assure that a single pump doesn't heat the fluid too hot. The pumps, like the IV pumps, can pump at dramatically different speeds. Like the hospital pumps, they sense that the fluid is flowing smoothly, or if their are problems.

Frankly my recent stay in the hospital wasn't complicated by pump problems like I've encountered in the past. Sleeping in a hospital has always been difficult for me, but when I get to sleep, nothing is much more annoying than a pump alarm caused by air bubbles forming in the lines. For me, they seemed to happen all the time in the middle of the night.

I cannot say if air bubbles can create problems in the Flaskwork device, but I'm sure it's something they deal with as the units operate for many days without human intervention while making the vaccine.

I have no idea all that's happening inside the cartridge, but all that matters is that you get DCVax-L out when it's finished doing it's thing.
