摘要： A needle guard having a retention mechanism coaxially disposed with a tip protector. The tip protector has first(50) and second (52) arms. The retention mechanism is sized and configured to engage a catheter hub (16). The retention mechanism has two pairs of cutouts forming first and second spring fingers (44) for gripping the catheter hub. The retention mechanism defines a through bore (48) extending through a proximal wall of the retention mechanism between the first and second arms.

摘要： Safety needle assemblies that include a needle (42) having a sharp distal tip and a needle tip protector (44) mounted on the needle are disclosed. The needle tip protector includes a first portion having a channel receiving the needle and a second portion attached to the first portion. The second portion has a proximal wall, an opening in the proximal wall receiving the needle, a sidewall extending distally from the proximal wall, first and second spring arms (78,80) extending transversely from opposite edges of the sidewall, and a third spring arm (82) extending distally from the sidewall. The first spring arm and the second spring arm extend at least partially around the first portion. The third spring arm includes a tab extending radially inward and configured to bear against the needle to deflect the third spring arm radially outward against a spring restoring force in a ready to use position.

摘要： Intravenous sets, port assemblies, and vascular access assemblies can include a vent device for venting gas trapped therein. The vent device can connect to a connector, such as a needleless port having a valve, and the connector connected to an adapter. The vent device can have a valve opener, an engagement body, and a gas-permeable vent incorporated with the valve opener. In use, the valve opener is moveable from an initial non-venting condition, in which the valve opener does not actuate the valve and is held in-register with the valve by the engagement body, to a venting condition, in which the valve opener is actuated to open the valve to allow gas to pass from within the system the connector is connected to then flow out through the gas-permeable vent.
