Catheter securement device
First Claim
1. A retainer configured for use with a medical article, the retainer comprising:
- a body member comprising,a channel formed therethrough and having a central axis, the channel being configured to retain at least a portion of the medical article within the body member with a retained portion extending entirely through the channel, the channel having a longitudinal access opening disposed on an underside of the body member to allow ingress of at least the retained portion of the medical article,a plurality of abutments extending generally normal to the central axis of the channel and configured to inhibit longitudinal movement of the medical article relative to the retainer, adjacent abutments of the plurality of abutments being spaced apart to form a plurality of slots therebetween, at least two slots providing an opening into the channel between the plurality of abutments,at least one mounting wing having a support surface disposed on the underside of the body member and to one side of the longitudinal access opening opposite the central axis, the support surface being disposed below the channel and at a distance spaced from the central axis which is greater than a distance between a lower extremity of the retained portion of the medical article and the central axis so as to inhibit contact between the retained portion of the medical article and a patient'"'"'s skin when the retainer is placed upon the patient'"'"'s skin, the support surface being configured to support the body member so as to prevent movement of the channel relative to the support surface and being angled relative to the central axis of the channel to define an incident angle of approximately seven degrees between the central axis of the channel and the patient'"'"'s skin; and
at least one anchor pad coupled with the retainer including an adhesive layer disposed on an underside thereon, wherein the adhesive layer is configured to contact a portion of a patient'"'"'s skin.

Abstract
A catheter securement device holds a medical article such as a catheter hub or a connector fitting in position upon the body of a patient and at least inhibits longitudinal movement of the medical article. The securement device includes a retainer and at least one anchor pad. The retainer forms a central channel into which at least a portion of the medical article is inserted. The retainer 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, inhibits motion of the medical article in proximal and distal directions through the central channel. For this purpose, the abutment surface(s) can lie either within or outside the channel.

1. A retainer configured for use with a medical article, the retainer comprising:
-
a body member comprising, a channel formed therethrough and having a central axis, the channel being configured to retain at least a portion of the medical article within the body member with a retained portion extending entirely through the channel, the channel having a longitudinal access opening disposed on an underside of the body member to allow ingress of at least the retained portion of the medical article, a plurality of abutments extending generally normal to the central axis of the channel and configured to inhibit longitudinal movement of the medical article relative to the retainer, adjacent abutments of the plurality of abutments being spaced apart to form a plurality of slots therebetween, at least two slots providing an opening into the channel between the plurality of abutments, at least one mounting wing having a support surface disposed on the underside of the body member and to one side of the longitudinal access opening opposite the central axis, the support surface being disposed below the channel and at a distance spaced from the central axis which is greater than a distance between a lower extremity of the retained portion of the medical article and the central axis so as to inhibit contact between the retained portion of the medical article and a patient'"'"'s skin when the retainer is placed upon the patient'"'"'s skin, the support surface being configured to support the body member so as to prevent movement of the channel relative to the support surface and being angled relative to the central axis of the channel to define an incident angle of approximately seven degrees between the central axis of the channel and the patient'"'"'s skin; and at least one anchor pad coupled with the retainer including an adhesive layer disposed on an underside thereon, wherein the adhesive layer is configured to contact a portion of a patient'"'"'s skin. - View Dependent Claims (2, 3, 4, 5, 6, 7)

8. A securement system comprising:
-
a medical article having a generally elongated body and a side member that projects away from the generally elongated body; and a retainer comprising, a body member having a proximal end and a distal end, a channel formed from the proximal end to the distal end and having a central axis, the channel being configured to retain at least a portion of the medical article within the body member with a retained portion extending entirely through the channel, the channel having a longitudinal access opening disposed on an underside of the body member, a first abutment extending generally normal to the central axis of the channel, a second abutment extending generally normal to the central axis of the channel, the second abutment spaced from the first abutment, a slot defined between the first and second abutment, at least two openings into the channel adjacent the first and second abutments at least one support having a lower surface disposed on the underside of the body member, the lower surface maintaining an angle of approximately seven degrees with respect to the central axis and preventing movement of the channel with respect to the lower surface, the lower surface being spaced from the central axis by a distance greater than a distance between a lower extremity of the retained portion of the medical article and the central axis so as to inhibit contact between the retained portion of the medical article and a patient'"'"'s skin when the retainer is placed upon the patient'"'"'s skin, and at least one anchor pad including a lower adhesive surface configured to attach to an epidermal layer of a patient. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)

17. A retainer configured for use with a medical article, the retainer comprising:
-
a body member comprising, a channel formed therethrough and having a central axis, the channel extending through an arc of greater than 180 degrees about the central axis, the channel being configured to retain at least a portion of the medical article within the body member with a retained portion extending entirely through the channel, the channel having a longitudinal access opening disposed on an underside of the body member to allow ingress of at least the retained portion of the medical article, one or more hips defined by a lower portion of the channel and disposed adjacent to the longitudinal access opening, at least two abutments extending generally normal to the central axis of the channel and configured to inhibit longitudinal movement of the medical article relative to the retainer, a slot formed between the at least two abutments, at least two openings into the channel adjacent the at least two abutments, at least one mounting wing having a support surface disposed on the underside of the body member and to one side of the longitudinal access opening opposite the channel axis, the support surface being disposed below the channel and preventing movement of the channel with respect to the support surface, the support surface having a proximal portion and a distal portion each supporting at least a portion of the one or more hips, the proximal portion being disposed at a first distance spaced from the central axis and the distal portion being disposed at a second distance spaced from the central axis that is greater than the first distance so as to define an incident angle of approximately seven degrees, each of the first and second distances being greater than a distance between a lower extremity of the retained portion of the medical article and the central axis so as to inhibit contact between the retained portion of the medical article and a patient'"'"'s skin when the retainer is placed upon the patient'"'"'s skin; and at least one anchor pad, including a lower adhesive surface configured to contact the patient'"'"'s skin. - View Dependent Claims (18, 19, 20)
