Abstract

A feeding tube medical apparatus having a catheter head and catheter that allows easy insertion and removal of the catheter within a patient needing enteral feeding. The invention also relates to a method for easy insertion and removal of the catheter. The catheter has a slim profile, a balloon bolster, and a tapered guide tube that promote easy insertion of the catheter down a patient'"'"'s mouth and into his or her stomach. In addition, the catheter head, containing ports for feeding, medicating, and filling the balloon bolster, is removably connected to the catheter so that it need not be inserted through the patient along with the catheter.

Claims

1. A medical apparatus comprising:

a catheter head having a large-lumen fitting and a small-lumen fitting;

a catheter attachable to the catheter head including a large lumen, a small lumen adjacent to the large lumen, a top portion, a bottom portion, and a balloon in communication with the small lumen; and

a guide tube having a distal end and proximal end attached to the top portion of the catheter at the proximal end.

2. The medical apparatus of claim 1 wherein the catheter head further comprises a first, a second, and a third port and a first and a second port cap operably associated with the first and second ports.

3. The medical apparatus of claim 2 further comprising a valve disposed in the third port.

4. The medical apparatus of claim 1 further comprising a guidewire.

5. The medical apparatus of claim 1 wherein the large-lumen fitting of the catheter head has a flat edge for interconnection with a flat surface of the large lumen of the catheter.

6. The medical apparatus of claim 1 wherein the large-lumen fitting of the catheter head is generally frusto-conical in shape for easy push insertion into the large lumen.

7. The medical apparatus of claim 1 wherein the catheter bears a position mark 2 cm from the bottom end.

8. The medical apparatus of claim 1 further comprising a ridge located on the bottom end portion of the catheter with a diameter at least 1 mm wider than the diameter of the catheter.

9. The medical apparatus of claim 1 wherein the distal end of the guide tube has a diameter wider than the diameter of the catheter.

10. The medical apparatus of claim 1 further comprising a seal sleeve with an interior diameter greater than the diameter of the catheter.

11. The medical apparatus of claim 1 further comprising a flange with a center opening greater than the diameter of the catheter.

18. The device of claim 1, wherein the catheter is configured and dimensioned to fit down a throat and into a stomach of a neonate.

12. A feeding tube device comprising:

a double-lumen catheter having a balloon, a small lumen for inflating the balloon in connection with a bottom portion of the double-lumen catheter and a large lumen for enteral feeding of a patient;

a guide tube attached to a top portion of the double-lumen catheter and having a tapered proximal end, wherein the guide tube-catheter assembly presents an overall profile substantially no wider than the catheter; and

a catheter head having a large-lumen fitting and a small-lumen fitting for removably connecting the catheter head to the large lumen and small lumen of the catheter.

13. The feeding tube device of claim 12 wherein the large-lumen fitting has a raised outer lip which causes a friction fit with the large lumen for ease of insertion but more difficult removal.

14. The feeding tube device of claim 12 wherein the double-lumen catheter bears a mark at its distal end for indicating when the catheter has been pushed far enough into position.

15. The feeding tube device of claim 12 further comprising a ridge located on the bottom end of the double-lumen catheter that prevents accidental removal of the catheter by requiring a tug for removal.

16. The feeding tube device of claim 12 wherein the distal end of the guide tube has a diameter wider than the diameter of the double-lumen catheter to ease passage of the catheter;

and wherein the guide tube is removable from the double-lumen catheter.

17. The feeding tube device of claim 12 further comprising a catheter seal sleeve with an interior diameter greater than the diameter of the double-lumen catheter for sealing the connection between the catheter and the catheter head.

19. A feeding tube device for a patient comprising:

a double-lumen catheter including a catheter balloon;

a guide tube removably connected with the double lumen catheter;

a guide wire for guiding the double lumen catheter and guide tube down the throat of a patient;

a catheter head for connecting to the double lumen catheter after removal of the guide tube and guide wire; and

a sleeve for sealing the connection between the catheter to the catheter head;

wherein the catheter head includes a feeding port, a medication port, and a balloon filling port;

wherein the feeding port and medication port are in fluid communication with the large lumen of the catheter for simultaneous introduction of medication and nutrition and the balloon filling port is in fluid communication with the small lumen of the catheter for filling the catheter balloon to secure the catheter in place along the patient'"'"'s stomach wall; and

wherein the catheter further includes a position mark and a ridge to better position the catheter in the patient'"'"'stomach.

20. The device of claim 19, further comprising a metal lumen fitting connected to the catheter head and coated with plastic to increase surface friction and better secure the connection between the catheter lumen and the catheter head.
