Abstract

In an aspirating and feeding device for insertion into a patient'"'"'s body there is an aspirating lumen and a feeding lumen. A set of primary and secondary orifices are placed through the tube for communication between the aspirating lumen and the exterior of the tube. The size of the primary and secondary orifices relate to each other such that the secondary orifices are smaller than the primary orifices. The feeding lumen has an external end portion to be disposed outside the body and an internal end portion to be disposed in the proximal segment of the small bowel. The internal end portion having an orifice therein for the discharge of food.

Claims

1. A feeding and aspirating device for insertion into a patient'"'"'s body, comprising:

a single walled tube, having an aspirating lumen and a feeding lumen therein, said aspirating lumen having an external end portion to be disposed outside the body, said feeding lumen also having an external end portion to be disposed of outside the body, and having an internal end portion to be disposed in the proximal segment of the small bowel, said internal end portion having an orifice therein for the discharge of food; and

a set of primary aspirating orifices through said single walled tube for constant communication between the aspirating lumen and the exterior of the tube; and

a set of secondary orifices through said single walled tube for constant communication between the aspirating lumen and the exterior of the tube, said secondary orifices having openings which are positionally fixed with relation to and smaller than the primary aspirating orifices.

2. The invention of claim 1 wherein the secondary orifices have an opening less than or equal to 1/3 the size of the opening of the primary orifices.

3. The invention of claim 2 wherein at least one secondary orifice is more proximal to the external end portion of the aspirating lumen than any of the primary orifices.

4. The invention of claim 3 wherein all of the secondary orifices are more proximal to the external end portion of the aspirating lumen than any of the primary orifices.

5. The invention of claim 1 wherein each secondary orifice corresponds to a primary orifice and is substantially equi-distant from the external end portion of the aspirating lumen as is its corresponding primary orifice.

6. The invnention of claim 5 wherein each secondary orifice is positioned 180°

around the tube from the corresponding primary orifice.

7. An aspirating device for insertion into a patient'"'"'s body, comprising:

a tube having an aspirating lumen therein, said aspirating lumen having an external end portion to be disposed outside the body;

a set of primary aspirating orifices in the tube for communication between the aspirating lumen and the exterior of the tube; and

a set of secondary orifices in the tube for communication between the aspirating lumen and the exterior of the tube, the opening of said secondary orifices being smaller than the opening of the primary orifices, each secondary orifice corresponding to a primary orifice and being substantially equi-distant from the external end of the aspirating lumen as the primary orifice to which it corresponds.

8. The invention of claim 7 wherein the opening of the secondary orifices is less than or equal to 1/3 the size of the opening in the primary orifices.

9. The invention of claim 8 wherein at least one secondary orifice is more proximal to the external end portion of the aspirating lumen than any of the primary orifices.

10. The invention of claim 9 wherein all the secondary orifices are more proximal to the external end portion of the aspirating lumen than any of the primary orifices.

11. The invention of claim 7 wherein each secondary orifice is positioned 180°

around the tube from the corresponding primary orifice.
