Abstract: 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. The proximal end or hose of the needle guard detaches for the needle housing and has a luer fitting for an infusion set. The catheter hub contains a lever capable of occluding the catheter to inhibit fluid flow.

Abstract: A catheter with a double membrane gasket and a locking needle guard is disclosed. The gasket prevents blood from seeping through the catheter hub. The locking needle guard prevents the user from inadvertent needle sticks.

Abstract: An I.V. catheter is described, including a catheter and hub assembly and a needle and hub assembly. A needle guard, including a tubular distal portion and a split proximal flange, is located about the needle at the distal end of the needle hub. The needle includes a slot near the needle tip. As the needle assembly is withdrawn from the catheter, the needle guard slides along the needle until the split flange engages the needle slot, which locks the tubular distal portion of the guard over the needle tip.

Abstract: A catheter assembly has a hub with an axial opening extending therethrough, the distal end of the opening having a standard size to accommodate the proximal section of a catheter securement insert having a passageway therethrough in alignment with the axial opening. A catheter is secured within the passageway in fluid communication with the axial opening.
