- 15 - CATHETER WITH IMPROVED FLASH PLUG ABSTRACT OF THE DISCLOSURE: A catheter device is described with a safety needle guard that covers and protects the needle after use of the device. The device includes a semi-tubular needle housing containing a flash chamber with a hollow needle extending from the distal end of the flash chamber. A tubular needle guard concentrically fits and slides within the needle housing. The needle guard has a longitudinal slot through which the mounting base of the flash chamber passes as the guard slides within the housing. The top of the semi-tubular housing is open so that a user may access the top of the tubular needle guard with a finger to urge the needle guard to an extended position from the distal end of the housing and in a surrounding position about the needle. As the needle guard attains its fully extended position about the needle, it locks in place in the needle housing. The flash plug assembly is improved to prevent blood covering the plug, by providing membrane means, which protect the plug and a vent hole which allows communication of the flash chamber and the porous plug, and also may be used in other catheter assemblies which do not employ a needle guard.
