Abstract

A ferrule for use as a medical device which maker mechanical connection with external connector tubes provided; the ferrule 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.

Claims

1. A feeding device comprising:

an elongated tube formed from a flexible material;

an inlet end portion formed from the flexible material and integrally connected to the elongated tube and defining first, second and third inlet port openings;

a ferrule disposed within said inlet end portion, said ferrule including,

a first inner wall defining a first main conduit,

a second inner wall defining a second main conduit,

a first inlet defining a first inlet conduit and providing fluid communication between the first inlet port opening and said first main conduit,

a second inlet defining a second inlet conduit and providing fluid communication between the second inlet port opening and said first main conduit,

a third inlet defining a third inlet conduit that provides fluid communication between said third inlet port opening and said second main conduit.

2. The feeding device of claim 1 wherein:

said inlet end portion defines a fourth inlet port opening; and

wherein said ferrule further includes;

a fourth inlet defining a fourth inlet conduit that provides fluid communication between said fourth inlet opening and said second main conduit.

3. The feeding device of claim 1;

wherein the first main conduit is aligned along a first main axis and the first inlet conduit is aligned along a first inlet axis offset from the first main axis; and

wherein the second main conduit is aligned along a second main axis and the third inlet conduit is aligned along a second inlet axis offset from the second main axis.

4. The feeding device of claim 1 wherein at least one of said first, second and third inlet ports includes gripping means for making mechanical connection with an external connector.

5. The feeding device of claim 4 wherein said gripping means includes:

at least one taper lock surface for forming a taper lock with a first external connector having first dimensions.

6. The feeding device of claim 5 wherein said gripping means further includes:

second taper lock surface for forming a taper lock with a second external connector having second dimensions.

7. The feeding device of claims 4 wherein said gripping means includes a threaded region about a portion of at least one of said first, second and third inlet conduits.

8. The ferrule of claim 4 wherein said gripping means includes a barbed gripping means for gripping an inlet port of a feeding device.

9. A feeding device comprising:

an elongated tube formed from a flexible material;

an inlet end portion formed from the flexible material and integrally connected to the elongated tube and defining first, second, third and fourth inlet portion openings;

a ferrule disposed within said inlet end portion, said ferrule including,

a first inner wall defining a first main conduit,

a second inner wall defining a second main conduit,

a first inlet defining a first inlet conduit that provides fluid communication between the first inlet port opening and said first main conduit,

a second inlet defining a second inlet conduit that provides fluid communication between the second inlet port opening and said first main conduit;

a third inlet defining a third inlet conduit that provides fluid communication between the third inlet portion opening and said second main conduit, and

a fourth inlet defining a fourth inlet conduit that provides fluid communication between said fourth inlet opening and said second main conduit.

10. A feeding device comprising:

an elongated tube formed from a flexible material;

an inlet end portion formed from the flexible material and integrally connected to the elongated tube and defining first and second inlet port openings;

a ferrule disposed within said inlet end portion, said ferrule including,

a first inner wall defining a first main conduit,

a second inner wall defining a second main conduit,

a first inlet defining a first inlet conduit that provides a fluid communication between the first inlet port opening and said first main conduit, and

a second inlet defining a second inlet conduit providing fluid communication between the second inlet portion opening said second main conduit.

11. The feeding device of claim 10 wherein said first inlet is offset from said first main conduit.

12. The feeding device of claim 10 wherein said first inlet includes gripping means for making mechanical connection with an external connector.

13. The feeding device of claim 10 wherein,

the first main conduit is aligned along a first main axis and the first inlet conduit is aligned along a first inlet conduit offset from the first main conduit;

and

the second main conduit is aligned along a second main axis and the second inlet conduit is aligned along a second inlet conduit offset from the second main conduit.

14. A feeding device comprising:

an elongated tube formed from a flexible material;

an inlet end portion formed from the flexible material; and

integrally connected the elongated tube and defining a plurality of respective inlet portion openings;

a ferrule disposed within said inlet end portion, said ferrule including,

a first inner wall defining a first main conduit,

a second inner wall defining a second main conduit.

a plurality of respective first inlets, each corresponding to a respective inlet port opening, and each for providing fluid communication between a respective inlet port opening and the first main conduit, and

a plurality of respective second inlets, each corresponding to a respective inlet port opening, and each for providing fluid communication between a respective inlet port opening and the second main conduit.
