1. An apparatus for removably connecting together a fluid supply tube and an intravenous catheter, said apparatus comprising:
- an adaptor having a tubular body defined between a forward end and a rear end, said forward end being configured to engage a hub of the catheter and said rear end being configured to receive an end of the fluid supply tube, said adaptor body for defining a longitudinal axis;
a support arm cantilevered radially outwardly from said adaptor;
a clip support element mounted on said support arm, said clip support element having an elongated parallelepiped shape extending generally parallel to said longitudinal axis, said clip support element being mounted on an outer end of said support arm at a central section of said clip support element, the connection between said support arm, said adaptor body and said clip support element permitting pivoting movement of said clip support element about said adaptor body such that depressing a rear end of said clip support element toward said adaptor body moves a forward end of said clip support element away from said adaptor body;
a clip comprising a forward latch configured to engage the hub, said clip slidably connecting with said support arm to move in a direction parallel to said longitudinal axis of said adaptor, said clip pivotably connecting to said adaptor to move said forward latch radially outwardly away from said forward end of said adaptor; and
an interengaging element maintaining said clip from sliding towards said froward end of said adapter, said interengaging element comprising ratchet teeth and a pawl which engages said teeth to prevent said latch of said clip from sliding towards said forward end of said adaptor.

Abstract
A tubular adaptor releasably interconnects an IV conventional catheter hub to fluid supply tubing. A latching clip slidably mounted on the adaptor cooperates with flange portions on the catheter hub to secure the interconnection between the hub 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° on the base into a low profile position, wherein the clip is close to the patient'"'"'s skin.

7. An apparatus for supporting and facilitating the changing of tubing connected to a catheter, said apparatus comprising:
-
an adaptor having a tubular body with a forward end configured to connect to a hub of a catheter, and a rear end configured to connect to a tubing; and a base for mounting on a patient'"'"'s skin, said base having a pair of upstanding legs spaced to define a space for receiving said adaptor body, said base legs having detents which fit within an annular groove on said tubular body in a manner permitting rotation of said adaptor about a longitudinal axis of said adaptor tubular body while remaining captured on said base. - View Dependent Claims (8, 9, 10, 11, 12)

13. A method of connecting a tubing to a catheter, said method comprising the steps of:
-
inserting a forward end of an adaptor into a rear end of a catheter hub; engaging said hub with a clip which is slidably mounted on said adaptor; sliding said hub rearwardly on said adaptor to grip the catheter hub in a gripping position; locking said clip to maintain said clip in said gripping position by means of interengaging structure on said clip and said adaptor; mounting said adaptor body in a base; attaching said base to a patient'"'"'s skin; and rotating the adaptor body from a position in which said clip is positioned away from said patient'"'"'s skin in a high profile position to a low profile position in which the clip is positioned close to the patient'"'"'s skin.

14. A method of connecting a catheter to a supply tubing, said method comprising the steps of:
-
connecting a forward end of a tubular adaptor to a rear of a catheter hub with the rear of the tubular adaptor being connected to a supply tubing; latching the adaptor to the catheter by means of movable latching structure positioned radially outwardly from one side of the tubular adaptor; positioning said adaptor into a base attachable to a patient'"'"'s skin; and rotating the adaptor within said base from a high profile position in which said latching structure extends upwardly to a low profile position in which said latching structure lies adjacent to the patient'"'"'s skin.
