The securement device includes a retainer and at least one anchor pad. The retainer includes an abutment wall and a slot. The slot has a labyrinth shape leading to a cradle part of the slot. At least a portion of the medical article is inserted into the cradle part through the slot. The abutment wall includes at least one abutment that abuts against a contact point or surface on the medical article to inhibit distal, longitudinal movement of the medical article. ## Claims ### Claim 1 A method of securing a medical article to a patient, the method comprising: providing a retainer having a body and first and second supports, the body defining a channel and including an abutment wall and a slot, the abutment wall extending generally normal to the channel, at least a portion of the slot forming a cradle and having an opening, the first support and the second support being disposed on an underside of the body and generally on opposite sides of the channel, the first support being connected to the second support via a web member so as to define an upper opening therebetween; inserting a first portion of a medical article into the slot through the opening; guiding the inserted portion of the medical article through the slot and into the cradle, at least a portion of the cradle being disposed under the first portion of the medical article when the first portion of the medical article is disposed within the cradle; and inserting a second portion of the medical article into the channel on a side of the abutment wall so as to prevent the medical article from being pulled through the retainer in at least one direction, at least a portion of the medical article being disposed above the upper opening and between the first support and the second support at least when the medical article is received within the channel. ### Claim 2 (depends on 1) The method of claim 1, wherein the slot has an inverted, hook-shape. ### Claim 3 (depends on 1) The method of claim 1, wherein the abutment wall extends generally normal to a longitudinal axis of the medical article. ### Claim 4 (depends on 1) The method of claim 1 further comprising elevating the first portion of the medical article above the patient's skin when the first portion is disposed within the cradle. ### Claim 5 (depends on 1) The method of claim 1 further comprising elevating the second portion of the medical article above the patient's skin when the first portion is disposed within the cradle. ### Claim 6 (depends on 1) The method of claim 1 further comprising adhering the retainer to a patient's skin. ### Claim 7 (depends on 6) The method of claim 6, wherein adhering the retainer to the patient's skin comprises exposing at least a portion of an adhesive surface and attaching the adhesive surface to the patient's skin. ### Claim 8 (depends on 1) The method of claim 1, wherein the second portion of the medical article has a greater diameter than the first portion of the medical article. ### Claim 9 (depends on 8) The method of claim 8, wherein the first portion of the medical article is a tube and the second portion of the medical article is a connector body. ### Claim 10 (depends on 9) The method of claim 9, wherein the second portion of the medical article includes a spin nut. ### Claim 11 A method of securing a catheter to a patient, the method comprising: attaching a catheter to an intravenous catheter anchoring device so as to restrict axial movement of the catheter in at least one direction relative to the device, the intravenous catheter anchoring device having a body and first and second supports, the body defining a channel and including an abutment wall and a slot, the abutment wall extending generally normal to the channel, at least a portion of the slot forming a cradle and having an opening, the first support and the second support being disposed on an underside of the body and generally on opposite sides of the channel, the first support being connected to the second support via a web member so as to define an upper opening therebetween; elevating at least a portion of the catheter above the patient's skin with the cradle of the catheter anchoring device; locating at least a portion of the catheter above the upper opening and between the first support and the second support at least when the catheter is received within the channel; and attaching the intravenous catheter anchoring device to the patient. ### Claim 12 (depends on 11) The method of claim 11 further comprising sliding the portion of the catheter through a slot in the catheter anchoring device. ### Claim 13 (depends on 11) The method of claim 11, wherein attaching the catheter anchoring device to the patient's skin comprises exposing at least a portion of an adhesive surface and attaching the adhesive surface to the patient's skin. ### Claim 14 (depends on 11) The method of claim 11, wherein a top surface of the catheter is uncovered by the catheter anchoring device when the catheter is attached to the catheter anchoring device. ### Claim 15 (depends on 14) The method of claim 14, wherein the uncovered top surface is of a spin nut. ### Claim 16 A method for securing a medical tube attached to a catheter relative to a patient, comprising: providing a retainer having a body and first and second supports, the body defining a channel and including an abutment wall and a slot, the channel being formed between two sides of the retainer and having a lower opening and an upper opening, the first support and the second support being disposed on the underside of the body and generally on opposite sides of the channel; inserting a medical tube through the slot and into the retainer; inserting a catheter attached to the medical tube through the lower opening and into the channel so that the catheter is axially aligned with a surface of the abutment wall, at least a portion of the catheter being disposed above the upper opening and between the first support and the second support; and securing the retainer relative to a patient's skin. ### Claim 17 (depends on 16) The method of claim 16, wherein securing the retainer relative to the patient's skin comprises exposing at least a portion of an adhesive surface of the retainer and attaching the adhesive surface to the patient's skin. ### Claim 18 (depends on 16) The method of claim 16 further comprising inserting the medical tube through an opening and into the slot, the opening being disposed on a lower surface of the abutment wall. ### Claim 19 (depends on 16) The method of claim 16 further comprising inserting the medical tube into a cradle of the retainer. ### Claim 20 (depends on 19) The method of claim 19 further comprising elevating at least a portion of the catheter above the patient's skin at least when the medical tube is disposed within the cradle.
