Abstract

The invention is related to a feeding tube (1, 11, 15) in particular for total parental nutrition and/or medicine dosing including at least one inner tubing (9), at least one lumen (2, 13), at least one sensing element, in particular an electrode (3), the sensing element being connected to at least one monitoring device by a wiring (4, 12, 17) for internal monitoring of a patient'"'"'s vital functions. The wiring (4, 12, 17) is at least partially wounded in tight contact with a surface of the inner tubing (9). Wherein the inner tubing (9) is at least partially surrounded by an outer tubing (8) in order to cover the inner tubing (9) and/or the wiring (4, 12, 17).

Claims

1. A feeding tube in particular for total parental nutrition and/or medicine dosing including at least one inner tubing, at least one lumen, at least one sensing element, in particular an electrode, the sensing element being connected to at least one monitoring device by a wiring for internal monitoring of a patient'"'"'s vital functions, the wiring being at least partially wound in tight contact with a surface of the inner tubing, wherein the inner tubing is at least partially surrounded by an outer tubing in order to cover the inner tubing and/or the wiring.

2. The feeding tube according to claim 1, wherein at least one opening is provided in the outer tubing at the location of the at least one sensing element to allow an access to the at least one sensing element.

3. The feeding tube according to claim 1, wherein the sensing element is formed by winding the wiring in a coil on said inner tubing.

4. The feeding tube according to claim 1, wherein the inner tubing has at least one recess on its surface that matches with the dimensions of the at least one sensing element and/or the wiring.

5. The feeding tube according to claim 1, wherein a surface area of the outer tubing has a slide spiral shape.

6. The feeding tube according to claim 1, wherein the outer tubing is built by a shrinking-wrapped tube so as to fit the outer tubing over the inner tubing by shrinking.

7. The feeding tube according to claim 1, wherein the outer tubing has a smaller inner diameter than an outer diameter of the inner tubing wherein the outer tubing is fitted over the inner tubing by stretching the inner tubing and insertion into the outer tubing.

8. The feeding tube according to claim 1, wherein the outer tubing and the inner tubing are made from one-piece wherein at least one inner lumen is formed in the center of the feeding tube and at least one outer lumen is formed near the surface of the tubing for guiding and protecting the wiring to be inserted into the at least one outer lumen.

9. The feeding tube according claim 8, wherein at least one groove is located at least one lumen which provides continuous opening in the least one outer lumen to enable a positioning of the wiring in the outer lumen from outside.

10. The feeding tube according to claim 1, wherein the inner tubing and/or the outer tubing is built by injection molding.
