Catheter securement device
First Claim
1. A securement device for securing a catheter to a patient'"'"'s skin, the catheter including a hub which has at least generally opposing slots that extend transversely to an axis of the catheter, said securement device comprising:
- a base coupled to an adhesive surface and configured to receive a section of the catheter in a position in which the catheter section extends generally along a longitudinal axis; and
a retainer coupled to said base by cooperating, interengaging structure between said base and said retainer, said retainer including a pair of opposing, arcuate rails which are spaced apart from each other in a direction generally parallel to a lateral axis, which lies perpendicular to the longitudinal axis and generally parallel to the base, the rails projecting away from said base in a direction that is generally normal to said base and generally parallel to a transverse axis, each rail extending along an arc defined within a plane which is positioned generally parallel to the longitudinal and transverse axes, each rail being sized to fit within a corresponding slot of the catheter hub, said rails including at least one pair of corresponding protrusions which project toward each other to decrease a distance between said rails, said distance between said protrusions being less than a distance between the slots of the catheter hub.

Abstract
A securement device retains an indwelling catheter at a desired incident angle while allowing incremental adjustments of the incident angle without disconnecting the catheter from the retainer. The retainer includes an arcuate slot which curves in a direction toward an insertion site of the indwelling catheter. The slot receives a portion of a hub of the catheter. Movement of the catheter hub along the arcuate path defined by the slot changes the incident angle of the catheter. The retainer also includes protrusions which project into the slot and capture a hub of the catheter at discrete positions within the slot. These positions correspond to commonly desired incident angles of the catheter for given medical applications. The retainer also connects to an anchoring base in order to secure the retainer to the patient'"'"'s skin proximate to the catheterization site.

- 15. A securement device for securing an indwelling catheter to a patient'"'"'s skin, the catheter including a hub, said securement device comprising a retainer having an arcuate slot sized to receive a portion of the hub, said slot extending in a transverse direction that is generally normal to the patient'"'"'s skin with the retainer coupled to the skin of the patient and curving toward an insertion site of the indwelling catheter, said slot being contoured to define a plurality of position openings arranged to be capable of retaining the portion of the hub at a plurality of positions relative to the patient'"'"'s skin, said position openings being located adjacent one another in the transverse direction.
- 22. A securement device for securing an indwelling catheter to a patient'"'"'s skin, said catheter including a hub, said securement device comprising a base coupled to an adhesive surface and a retainer coupled to said base by cooperating, interengaging structure between said base and said retainer, said retainer including means for retaining the hub of the catheter in at least a first position and a second position relative to the base with an incident angle of the indwelling catheter varying between said first and second positions, with the first position interposed between the base and the second position.
-
30. A method of adjusting an incident angle of an indwelling catheter comprising the steps of:
-
providing retainer having an arcuate slot which curves in a direction toward the insertion site of the indwelling catheter; positioning a portion of a hub of the catheter within the slot; securing the catheter hub in a first position within said slot to establish a first incident angle of the catheter; sliding said catheter hub within said slot along the arcuate path defined by said slot to a second position without sliding the hub through the slot in a direction perpendicular to the slot; and securing said catheter hub in the second position within the slot to establish a second incident angle of the catheter. - View Dependent Claims (31, 32, 33, 34)

- 35. A securement device for securing a medical line to a patient'"'"'s skin at a plurality of incident angles, said securement device comprising a retainer including a slot that extends away from the patient'"'"'s skin in a transverse direction with the retainer coupled to the skin of the patient, said slot having at least first and second sections lying adjacent to each other in the transverse direction, each slot section conforming to at least a portion of the medical line.
