Abstract

An anchoring system includes a securement device having an anchor pad with a flexible retainer opening that receives a portion of a medical article, such as a catheter, to hold it securely in place. A locating mechanism in the form of posts positions and holds the catheter in position and limits rotational movement of the catheter. The anchor pad is secured to a patient'"'"'s skin by adhesive.

18. An anchoring system for securing a medical article to the body of a patient, comprising:

a retainer including a lower layer that defines a receiving area for receiving a portion of the medical article, an upper layer, a first post support and a second post support, at least a portion of the upper layer being flexible so as to move between a closed position in which at least a portion of the upper layer extends over at least a portion of the receiving area and an open position in which the receiving area is at least partially open, the first and second post supports extending across at least a portion of the receiving area and between the lower layer and the upper layer, the first post support being disposed on a side of the receiving area, the second post support being disposed on the other side of the receiving area and spaced from the first post support so as to receive at least a portion of the medical article therebetween.

19. An anchoring system according to claim 18, wherein the upper layer comprises a flexible material.

20. An anchoring system according to claim 18, wherein the open receiving area is sized to receive the portion of the medical article.

21. An anchoring system according to claim 18, wherein at least one of the first and second post supports extends generally upward from the lower layer.
