Abstract: A tubular adaptor releasably interconnects a conventional IV catheter hub to fluid supply tubing. A latching clip slidably mounted on the adaptor cooperates with flange portions on the catheter to secure the interconnection between the proximal end of the catheter and the adaptor. The adaptor is snapped into a base attached to the patient's skin by an adhesive pad. After the catheter connection is made, the adaptor, together with the clip, is rotated about 90.degree. on the base into a low profile position, wherein the clip is close to the patient's skin.

Abstract: A sideport connector for an IV catheterization system is disclosed in which a secure connection can be maintained with standard Y-shaped sideport connectors, such as a septum-type connector. The connector of the present invention comprises a clip having a collar which slidably and, optionally, rotatably engages the septum in order to prevent accidental disengagement. The clip is prevented from disengaging motion by, preferably, a ratchet-pawl mechanism. In another embodiment, the clip can be mounted on the branch of the Y-shaped sideport. The connector also comprises a needle shield or, optionally, a cap to prevent self-injection and contamination.
