1. For use in various combinations between a feeding tube set and a catheter;

  • an adaptor, a connector, and an adaptor hood;

    said adaptor comprising a first generally tubular member having an upper end adapted to be mounted on the distal end of a feeding tube and a lower end adapted to be inserted into the upper end of either said connector or into said adaptor hood, the outer surface of said adaptor being characterized by a series of steps of progressively smaller diameters from the upper to the lower end thereof and including at least one inverted, slightly conical section, and a ring member projecting radially from said upper end of said first tubular member in a longitudinal plane and adapted to have a locking plug of said connector removably secured therein;

    said connector comprising a second generally tubular member mounted on the proximal end of a catheter and having an open end with any one of a plurality of inner diameters and adapted to receive therein the stepped lower end of said adaptor, a locking plug projecting radially from the upper portion of said second tubular member on a flexible, resilient arm with said plug being adapted either for plugging said open upper end of said second tubular member when no adaptor is received therein or for being lockingly engaged in said adaptor ring member when said adaptor is received in said open upper end of said connector to prevent inadvertent separation of said adaptor and said connector; and

    said adaptor hood comprising a third generally tubular member having an open upper end, an inner bore which tapers inwardly in a downward direction, and a tip at its lower end with the outer surface thereof being provided with a luer taper for interfitting engagement thereof in the open upper end of a connector having a bore with a luer taper, which connector is mounted on the proximal end of a catheter.
