If you pump to maximum inflation and the bulb becomes flat (or partially flat) and does not refill, it usually means there is no more fluid left in the reservoir—you have transferred all of the available fluid into the cylinders.
If this happens consistently at the same point during inflation, it suggests a fluid-volume issue. If it happens only occasionally, or at different points during inflation, I would be more suspicious of a mechanical problem with the pump itself.
If you’re unsure which is the case, your surgeon can help evaluate the device and determine what’s going on.
