Abstract
Abstract A catheter anchoring device is provided for securely anchoring a catheter to a patient's skin. The catheter anchoring device is particularly well suited to secure an epidural catheter proximate to an insertion site. The catheter anchoring device includes a plurality of channels which receive a section of the catheter body such that a portion of the received section of the catheter body lies generally transverse to an axis defined by the indwelling portion of the catheter. An additional anchoring device also can be used to anchor a catheter/fluid supply tube interconnection to the skin of a patient. In connection with epidural catheterization, one anchoring device can be attached to the anterior of the patient's torso, and the other anchoring device can be positioned on the posterior of the patient's torso and proximate to the point of insertion. This arrangement improves the comfort of the patient and makes the interconnection between the catheter and the fluid tube more readily accessible.
