Abstract
A catheter device is disclosed which contains a catheter in an insertion needle. The insertion needle is attached to a needle hub which contains a flash chamber. Within the flash chamber the proximal end of the needle is connected to a clear plastic tube so that flash is initially determined in this tube; overflow flash is then caused to flow into the larger flash chamber from the flash tube.
