Abstract
A ferrule is provided which comprises an inner wall defining a conduit extending between an inlet opening and an outlet opening; a first taper lock surface is defined by a first region of the inner wall for forming a taper lock with a first connector portion having first dimensions; and a second taper lock surface is defined by a second region of the inner wall for forming a taper lock with a second connector portion having second dimensions.
Claims20
For use in a feeding tube formed from flexible material, a ferrule comprising:
- an inner wall formed from a hard substantially nondeformable material which defines a conduit extending along a central axis between an inlet opening and an outlet opening;
- a first taper lock surface defined by a first region of said inner wall which is inclined relative to the central axis so as to be dimensioned as a first luer adapted for connection with a first connector portion having first dimensions corresponding to the first luer;
- and
- a second taper lock surface defined by a second region of said inner wall which is inclined relative to the central axis so as to be dimensioned as a second luer adapted for connection with a second connector portion having second dimensions corresponding to the second luer.
