A catheter securement device (100) holds a medical article such as a catheter hub (430) or a connector fitting (300) in position upon the body of a patient and at least inhibits longitudinal movement of the medical article. The securement device (100) includes a retainer (120) and at least one anchor pad (110a, 110b). The retainer (120) forms a central channel (140) into which at least a portion of the medical article is inserted. The retainer (120) includes at least one abutment that can abut against a contact point or surface on the medical article. The abutment, in conjunction with a second abutment and/or a tapering shape of the central channel (120), inhibits motion of the medical article in proximal and distal directions through the central channel (140). For this purpose, the abutment surface(s) can lie either within or outside the channel (140). |
