International ClassA61M 005/00AbstractA winged catheter introducer is disclosed. The catheter introducer has a catheter, a robe attached to the catheter and a winged intermediate member between the catheter and the robe. Within the catheter and the robe is a needle with a stylet attached to it. The stylet is attached to a hub which facilitates the pulling of the needle out of the catheter and through the robe. Attached to the robe is an adapter with a septum attached to it. The needle is provided with an opening extending from the needle wall to the needle lumen. A shielding device is provided which is attached to the adapter. The shielding device includes a needle container which is designed to trap the needle. A needle shield is provided inside the needle container. The needle is provided with an area of enlarged diameter. This area of enlarged diameter interacts with the needle shield when the needle is withdrawn from the catheter and robe and into the needle container. The needle shield is provided with an orifice through which the needle and stylet can fit but through which the area of enlarged diameter cannot pass. When the needle is withdrawn from the catheter and tube and into the needle container, it is trapped by the needle shield. The needle shield is also provided with a transverse wall which snaps over the point of the needle.Field of SearchHaving means for preventing reuse of deviceHaving structure for controlling depth of insertion of body piercer Means for securing conduit to body Having cover or protector for body entering conduit Cover or protector for body entering conduit movable axially relative to one another Having flow closing or opening means (e.g., plug, cap, seal, etc.) Body inserted tubular conduit structure (e.g., needles, cannulas, nozzles, trocars, catheters, etc.) Body piercing condit (e.g., needle, etc.) And used as conduit manipulator (e.g., foldable gripper wings, etc.) BODY FLUID, DEVICES FOR PROTECTION THEREFROM (E.G., AIDS, HEPATITUS, ETC.) | |
