Abstract: A safety catheter device has a clip guard that covers the needle tip protector or safety needle clip from the time that the device is shipped out in the ready to use position, through its use as a safety catheter device, to when the clip guard and the safety needle clip enclosed by the clip guard is removed from the catheter hub after the catheter extending from the catheter hub has been correctly placed into the vein or artery of the patient. A clip cup may be added to provide an additional level of protection for the safety needle clip and the sharp distal tip of the needle contained therein. Safety needle clips of different configurations used with the safety catheter device are described.

Abstract: A closed system catheter (CSC) assembly has a catheter hub assembly and a needle insertion assembly that includes a needle, a needle housing and a clip guard housed in a distal compartment of the needle housing. The clip guard has a chamber having fixedly enclosed therein a safety clip. The safety clip has two elongated arms with distal grippers and barriers that naturally bias toward each other. When the barriers are biased outwardly away from each other by the needle passing between them, the distal grippers are effected to fixedly hold the proximal end of the catheter hub of the catheter hub assembly. When not biased by the needle, the barriers return to their naturally inward biased state to cause the distal grippers to release their hold of the catheter hub, such that the clip guard and the catheter hub may be separated from each other. The barriers form a distal stop to prevent the needle from re-emerging from the safety clip.

Abstract: A safety catheter assembly has a clip guard that covers and protects the needle clip from the time that the catheter assembly is shipped out in the ready state, through its use where the distal tip of the needle is entrapped in the needle clip after use, and to when the clip guard and the safety needle clip housed therein are removed from the catheter hub. A passive safety system of the needle clip couples the catheter hub and the needle housing in the ready state and during the use of the catheter assembly, and releases the catheter hub from the needle housing once the contaminated needle tip is captured in the needle clip. A wiper provided to the catheter assembly wipes blood from the needle to prevent exposure of the contaminated blood. The wiper may also act to retain a septum in the catheter hub. The clip guard may be adapted to be used with a catheter hub having a multiuse seal member.

Abstract: A safety catheter assembly that may be a closed system catheter (CSC) has a seal member proximal a septum in the catheter hub. In a first embodiment, the seal member may be a cylindrical sleeve whereto a locking portion of a needle clip is positioned to fixedly hold the needle clip inside the catheter hub in a ready state. In a second embodiment, the needle clip is housed in a substantially cylindrical seal member. The seal member with the needle clip therein and the catheter hub are fixedly coupled together in the ready state. In a third embodiment, a retainer member at the catheter hub couples the needle clip to the catheter hub in the ready state and the seal member is distal the retainer member. In all the embodiments, the seal member may act as a reservoir for fluid in the interior cavity of the catheter hub that may back flow past the septum.

Abstract: A fluid or blood diverter is provided in the needle housing of a needle assembly for redirecting the inflowing blood to a distal section of the fluid diverter that may be enclosed by the distal portion of the needle housing so that a clinician can readily view the blood flash without having to look back to the flashback chamber at the proximal portion of the needle housing. At the distal section, the inflowing blood is redirected to the flashback chamber. The needle housing with the blood diverter is adapted to be used in safety catheter needle assemblies that may include a passive needle safety control mechanism including a clip guard. Different ways of coupling the needle housing and the clip guard with catheter hub assemblies with and without passive blood control are also described.
