ABSTRACT:
A skin mounted retention disc for maintaining a catheter indwelling comprises an elastomeric disc having a centrally disposed bore therethrough dimensioned to receive the catheter. About the periphery of the elastomeric disc is a plurality of very small holes to enable the disc to be sutered to the skin. Integrated to and extending upwardly from the elastomeric disc is a projection having a helically disposed channel therein for engaging the catheter as the catheter tube is wrapped about the disc after exiting the skin. A connecting tube having low release force connectors at either end is secured to the disc and links the catheter to a drainage bag. Because the force required to break the connection between the connecting tube and either the drainage bag or the catheter is less than the force required to dislodge the skin mounted retention disc, the connecting tube serves as a safety release to prevent the disc from becoming dislodged should the patient stray from the drainage bag.
