ABSTRACT:
A device which will permit the introduction of a length of catheter tubing through a needle and into the epidural space of a patient wherein the chance of the tubing being kinked is substantially reduced. In one version, an adapter having two opposing protruding sections is provided with one protrusion fitting inside the hub cavity of an epidural needle and the other extending outwardly to provide a finger engaging orifice surface. With one of the protruding sections placed in the needle hub cavity a continuous passageway is provided from the outwardly protruding section having the finger engaging surface and through the passageway of the adapter which will be aligned with the passageway in the epidural needle ultimately communicating with the needle. In an alternative embodiment, a protruding section extends from the hub of an epidural needle and a continuous passageway is provided therethrough to the needle as well as the protrusion providing a finger engaging surface so that the small diameter tubing can be easily fed therein.
