ABSTRACT:
A retention bolster for a percutaneous catheter is disclosed having a convexly curved exterior surface which contacts the epidermal surface of a patient. The retention bolster slides over a catheter until contacting the skin of the patient at the catheter exit site. When secured in place, the retention bolster rocks along contacting portions between its convexly curved surface and the epidermal surface of the patient in response to movement of the catheter about the exit site, thereby alleviating the added pressure that would otherwise be applied by this movement. Upon the release of lateral pressure against the catheter device, the bolster returns to its original upright position. In a second disclosed embodiment, a flange is provided which extends from the main body of the bolster which defines a bore that is also sized for slidably receiving and supporting the catheter, and which provides for angled attachment of the catheter relative to its exit site.
