Abstract

A securement device includes a simply-structured retention mechanism that permits a portion of a catheter hub or a similar medical article to be easily anchored to a patient, without the use of tape or needles and suturing. A unitary retainer desirably includes a base defining a locator mechanism. The locator mechanism interacts with a fitting of the medical device so as to position the medical device relative to the retainer. The locator mechanism also desirably guides the medical device fitting into contact with an adhesive member mounted on an outer surface of the retainer. In one form, the locator mechanism includes one or more posts that engage mating holes defined in the medical device fitting. In other forms, the locator mechanism includes a cradle defining an arcuate channel to receive a convex surface of the medical device, or a recess shaped to matingly receive the fitting. The retainer is attached to a flexible anchor pad that includes an adhesive bottom surface, which can be attached to the patient'"'"'s skin. In use, a health care provider positions the medical device fitting on the retainer in a position established and guided by the locator mechanism, and attaches the fitting to the retainer via the adhesive member.

26. A securement device for securing a fitting to a body of a patient, the fitting having laterally extending wings, the securement device comprising:

a generally planar base layer having a mounting surface at least partially covered by adhesive for attaching the securement device to the patient'"'"'s body, and a receiving area oriented so as to face away from the patient'"'"'s body and positioned to contact at least portions of the laterally extending wings of the fitting, the mounting surface being defined on one side of the base layer and the receiving area being accessible from an opposite side of the base layer; and

a retainer layer being attached to an upper side of the base layer and having an internal wall, the internal wall extending through the retainer layer so as to expose the receiving surface of the base layer at least when the fitting is retained by the securement device, the internal wall being configured to interact with the fitting so as to coarsely position the fitting on the receiving area relative to the retainer layer.

27. A securement device for securing a fitting to a body of a patient, the fining including a first lateral wing and a second lateral wing, the securement device comprising:

a flexible anchor pad having a mounting surface at least partially covered by an adhesive layer for attaching the securement device to the body of the patient; and

a retainer disposed on an opposite side of The anchor pad and having a first deflectable structure and a second deflectable structure, at least a portion of each deflectable structure being arranged generally parallel to the anchor pad so as to define a receiving space therebetween at least when the fitting is retained by the securement device, the receiving spaces being disposed symmetrically about a central location between the first and second deflectable structures, each receiving space configured to receive at least a portion of a corresponding lateral wing of the fitting, and a first actuator and a second actuator, the first actuator and the second actuator projecting away from each other, whereby moving the first actuator in a first direction causes the first deflectable structure to move away from the central location so as to permit at least a portion of the first lateral wing to be placed in the corresponding receiving space, and whereby moving the second actuator opposite to the first direction causes the second deflectable structure to move away from the central location so as to permit at least a portion of the second lateral wing to be placed in the corresponding receiving space.

28. A securement device as in claim 27, wherein at least a portion of each receiving space has at least one dimension that has a generally similar shape to a shape of the fitting and is sized in a longitudinal direction so as to not be larger than the corresponding wing.
