1. A catheter retainer, wherein said retainer is removable independently of said catheter, comprising:
- a base plate further comprising a lower surface disposed to attach to a patient, a generally dome-shaped raised upper surface, a peripheral surface, a transversely-disposed catheter channel defined in said upper surface; and
a lid, said lid having closed and open positions and further comprises an inverted dish-shaped lower surface conformal to said upper surface, a downwardly-extending wall disposed to engage said peripheral surface of said base plate when said lid is in said closed position, a downwardly-opening V-slot in said wall;
wherein said catheter channel has first and second ends, wherein said first end aligns with said V-slot when said lid is in said closed position thereby forming a first opening disposed to retain said catheter, wherein said second end has a C-shaped notched defining a second opening through which said catheter enters said patient, said notch being substantially wider than the diameter of said catheter, and wherein said catheter channel has a centrally-positioned locating region, and wherein said lid in said closed position completely covers said second opening.

Abstract
An epidural catheter retainer has an integral base and hinged lid. The base is attached to the skin and has a side opening through which the catheter can be inserted sideways into the retainer. A channel extends laterally across the base and has protrusions to grip the catheter. When the lid is closed, it covers the side opening and is held down by a catch. The underside of the lid has teeth or the like to grip the upper side of the catheter so that the retainer isolates that part of the catheter in the body from force exerted on its other end.
