Abstract

An apparatus, for placing a feeding tube in the stomach of the human or animal body, has:

a hollow needle, which is surrounded by a sleeve, for providing an opening in the abdominal wall and the stomach wall and for bringing the sleeve into the opening:

the tube, which has a first draw member at its one end:

and a thread-like second draw member, which may be introduced through the sleeve, for drawing the tube from the cavity of the stomach into the opening. The connection between the first and the second draw members can be produced inside the stomach. This is achieved in that the second draw member has an expandable loop at its inner end and the first draw member has a coupling element which may pass through the loop and be held fast by contraction of the loop.

Claims

1. Apparatus for placing a feeding tube in the stomach of the human or animal body, comprising:

a hollow needle, surrounded by a sleeve, for providing an opening in the abdominal wall and the stomach wall and for bringing the sleeve into the opening;

the tube, which has a first draw member at its one end; and

a thread-like second draw member, which may be introduced through the sleeve, for drawing the tube from the cavity of the stomach into the opening, the second draw member having an expandable loop at its inner end and the first draw member having a coupling element which may pass through the loop and be held fast by contraction of the loop.

2. Apparatus according to claim 1, wherein at least one side of the loop is under a tension which seeks to move it away from the other side.

3. Apparatus according to claim 1, wherein the loop may be expanded by a relative displacement of its sides.

4. Apparatus according to claim 1, wherein the first draw member, associated with the tube, is formed from a wire, preferably of metal.

5. Apparatus according to claim 1, wherein the length of the first draw member is greater than the distance between the cavity of the stomach and the mouth of the patient to be treated.

6. Apparatus according to claim 5, wherein the first draw member is bent or folded in the region of its inner end in the shape of a Z.

7. Apparatus according to claim 1, wherein the tube and at least a part of the first draw member form a first prefabricated apparatus part.

8. Apparatus according to claim 7, wherein the first prefabricated apparatus part is packed in a sterile wrapping.

9. Apparatus according to claim 1, wherein the hollow needle and the second draw member form a second prefabricated apparatus part.

10. Apparatus according to claim 9, wherein the second prefabricated apparatus part is packed in a sterile wrapping.

11. Apparatus according to claim 1, wherein a covering cap, for covering the opening on the outside, is associated with said apparatus.

12. Apparatus according to claim 11, wherein a hole, through which the tube may be passed, is arranged in the covering cap.

13. Apparatus according to claim 11, further including a clamping device for securing the tube to the covering cap in a clamping manner.

14. Apparatus according to claim 11, wherein the covering cap has, on its exterior, a groove-like recess for receiving the tube.

15. Apparatus according to claim 14, wherein the tube may be clamped in the recess.

16. Apparatus according to claim 14, wherein the whole end of the tube protruding from the covering cap may be inserted in the groove-like recess.

17. Apparatus according to claim 1, wherein arranged on the tube is a flange which, when the tube is placed inside the patient, abuts against the inside of the stomach wall.

18. Apparatus according to claim 17, wherein the tube includes an inner part, which remains inside the stomach when the flange abuts against the stomach wall, the inner part forming a loop, and the end thereof remote from the flange being detachably secured to the flange.

19. Apparatus according to claim 1, wherein the tube has a cone at its end, to ease insertion.
