Abstract

An anchoring system for an elongated medical article comprises an anchor pad and a retainer mounted upon the anchor pad. The retainer includes a base, a cover, and a compressible member including a receptacle into which the medical article to be retained is placed. When the cover is closed, the medical article is secured within the receptacle by the pressure of the compressible member and the cover upon the medical article. One or more biasing members act upon the compressible member to increase the frictional forces acting on the retained section of the medical article. The receptacle may form a channel that follows a curved path through the retainer. The retainer may also include guide extensions to support the medical article along a transverse bend toward the skin of the patient.

34. A retainer as in claim 21 further comprising a guide extension having a curvilinear surface over which the medical article can track so as to smoothly transition a section of the medical article along its length from a longitudinal orientation to an orientation angled to the skin of the patient.

35. A retainer as in claim 21, wherein at least a portion of the cover includes an adhesive layer.

36. A retainer as in claim 35, wherein the adhesive layer overlies at least a portion of the inner wall when the cover is in the closed position.

37. A retainer as in claim 21 additionally comprising a flexible coupling between the cover and the base.

38. A retainer as in claim 37, wherein the flexible coupling forms a unitary structure with at least one of the base and the cover.

39. A retainer as in claim 37, wherein a longitudinal length of the flexible coupling is less than a longitudinal length of at least one of the base and the cover.

40. A retainer as in claim 21, wherein at least a portion of the inner wall includes an adhesive layer disposed so as to contact the secured medical article.

41. A retainer as in claim 22, wherein the cover produces compressive stresses within the compressible member that bear against the portion of the medical article when received within the receptacle and the cover is in the closed position.

42. A retainer as in claim 22, wherein the receptacle is a channel.

43. A retainer as in claim 22, wherein a portion of the compressible member is inwardly deform able so as to decrease the size of at least a section of the receptacle.

44. A retainer as in claim 22, wherein at least a portion of the receptacle has a generally circular cross-sectional shape that defines an opening into the receptacle portion.

45. A retainer as in claim 22, wherein the receptacle has a generally circular, but truncated, cross-sectional shape that extends about an axis of the receptacle by greater than 180°

.

46. A retainer for a medical article, the retainer comprising:

a base;

a cover coupled to the base so as to move at least from an open position to a closed position, the cover being sized to extend longitudinally beyond the base at least when the cover is in the closed position, at least a portion of the cover including an adhesive layer;

a compressible member, at least a portion of the compressible member being disposed between the base and the cover at least when the cover is in the closed position, the compressible member defining at least in part a curvilinear receptacle configured to receive at least a portion of the medical article, at least a deformable portion of the compressible member being deformable so as to bear against the secured portion of the medical article when received within the receptacle and the cover is in the closed position, the compressible member being sized so that the cover extends laterally and longitudinally beyond the compressible member at least when the cover is in the closed position; and

an anchor pad having at least a portion of a first side covered with an adhesive layer to adhere the anchor pad to a patient'"'"'s skin, and an opposing second side supporting the base.

47. A retainer as in claim 46, wherein the adhesive layer overlies at least a portion of the receptacle when the cover is in the closed position.
