Abstract
A flash chamber having a self-closing valve for use with a catheter is described. The flash chamber, which is connected to the catheter, precludes blood leakage as a needle is removed from the catheter and an IV unit is coupled to the catheter. The flash chamber permits the practitioner to visually verify that a blood vessel has been punctured and includes a self-sealing valve that prevents blood from flowing out of the flash chamber as the needle is removed and the IV unit is attached.
