When Cristina Peck wants to give blood to help Paul Rivers, a nurse uses a blood collection system called Vacutainer to collect her blood. This system uses the power of vacuum to collect blood. To do this a vein has to be pricked with the needle and then a tube must be pricked too with the other side of the needle then the vacuum does the rest. In the film we see that the tube is already pricked to the needle, so it wouldn't work.
