Abstract: A tip protector (30) for a safety catheter (10) includes an outer member (34) releasably engaged with the interior cavity of the catheter hub (16). The outer member (34) includes a generally fixed radially outwardly projecting portion (127, 134) to provide a holding force, and an inner member (32) axially shiftably received within the outer member (34). A needle cannula (22) received in the inner (32) and outer members (34) is operable to axially shift the inner member (32) between a distal position wherein the distal tip (24) extends distally of the tip protector (30), and a proximal position wherein the distal tip (24) is within the outer member (34). The holding force of the outer member (34) to the interior wall of the catheter hub (16) remains substantially constant irrespective of the position of the inner member (32) between the distal and proximal positions.

Abstract: A safety catheter includes a catheter hub (16), a catheter tube (18), a needle hub (20), a needle cannula (22) having a distal tip (24), and a tip protector (30). The tip protector (30) includes an outer member (34) having a flexible tab (130) configured to releasably engage with the catheter hub (16) and release therefrom upon inward flexing of the tab (130). An inner member (32) is positioned entirely within the outer member (34) and has a portion (64) that impedes inward flexing of the tab (130) when disposed adjacent thereto. The inner member (32) is axially shiftable relative to the outer member (32) between a first position wherein the needle tip (22) is distal of the tip protector (30) and the inner member portion (64) is disposed adjacent the tab (130) to impede release from the catheter hub (16), and a second position wherein the tip (22) is within the outer member (34) and the inner member portion (64) is no longer adjacent the tab (130) and no longer impedes release from the catheter hub (16).

Abstract: An enclosed needle catheter insertion device (10) includes a catheter (12) and a needle insertion device (14) which are held together by cooperating arms (52, 53) with one or more detents (56) cooperating with a radially projecting surface (26) of the catheter hub (16). Insertion device (14) includes a guard housing (30) to enclose a needle (34) in a shielded position and a support housing (32) supporting the needle (34) for movement between a ready position, with the tip (36) of the needle (34) exposed, to the shielded position. Cooperating lock elements (47, 78) are provided for the housings (30, 32) which are positioned to define a lock actuation stage between the ready and shielded positions, whereat the needle is still within a passageway (54) defined by the cooperating arms (52, 53).

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 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: The present disclosure describes various catheters that address potential recoil issues. Such catheter may contain multiple lumens that allow for the discharge of infusants a various points on the catheter distal end. Further, multiple openings may be present on the distal end of the catheter. The openings can be covered with a membrane that ruptures at a designated flow pressure. The catheter tip can contain blind holes that remain covered, and are only opened to become active when required. Such catheters can allow for multiple infusant flow exits, rather than a singular steady jet exiting the distal end of the catheter.

Abstract: An enclosed needle catheter insertion device includes a catheter assembly (12) and a needle insertion device (14) having a needle guard housing (20) to enclose a needle cannula (24) in a shielded position and a needle support (22) supporting the needle cannula (24) for movement between a ready position, with the tip (28) of the needle cannula (24) exposed, to a shielded position with the needle cannula (24) within the needle guard housing (20). Movement of the needle support (22) and the needle cannula (24) relative to the needle guard housing (20) is accomplished by manual manipulation of a gripping component (40) external of the needle guard housing (20). A separate, proximal end cap (60) external of the needle guard housing (22) encloses a proximal portion (55) of the needle guard housing (20), and is affixed to the needle support (22).

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.
