ABSTRACT:
A catheter hub to nose engagement for securely engaging the hub of a catheter to the nose of a catheter emplacement unit is described. The attachment mechanism may be as simple as an elastic tube which provides an interference fit between the catheter hub and the nose of the emplacement unit. In an alternate embodiment the nose has a longitudinal slot to provide a split nose tip. The split nose tip is held in a separated position by the passage of a cannula therethrough and an enlarged burr end securely engages the hub and nose together. In another embodiment the nose has a longitudinally tapered nose tip and the tapered nose tip has an enlarged burr end to securely engage the hub and nose together. In a further embodiment the nose has an internal undercut in which an elastic plug is secured which is positioned between the catheter hub and nose. The elastic plus has a through hole having a diameter slightly smaller than the diameter of a catheter needle such that when the needle is inserted into the through hole the outer diameter of the elastic plug is expanded.
