Abstract

A probe, particularly for enteral feeding of living creatures, with a balloon coordinated to the insertion end of the probe tube, the balloon being fillable with liquid and emptiable in the inserted condition. The probe tube end is secured on a pilot probe and is detachable from the outside.

Claims

1. A probe means, particularly for enteral feeding of living creatures extending from the outside in an inserted condition in the creatures, comprising

a hollow probe tube defining an insertion end,

a balloon constituting an end portion of said probe tube being coordinated to said insertion end of said probe tube and communicating therewith for filling the balloon, said balloon being adapted to be filled with liquid through said probe tube,

a separate pilot probe along said probe tube constituting exclusively means for initially inserting said balloon in a push-in path and said insertion end of said probe tube partially into the living creature,

means for emptying said balloon in an inserted condition detached completely from said pilot probe,

said pilot probe extending up to said end portion of said probe tube, grasping said balloon at a portion other than an end of said balloon, said pilot probe non-fluidly communicating with said balloon, and being completely separable from said balloon, said pilot probe further being removable from the living creature without said balloon, the latter remaining in communication with the outside via said probe tube.

2. The probe means according to claim 1 wherein

said pilot probe is formed with a stick-in space,

said balloon has a balloon wall,

a loop formed by said balloon wall is clamped in said stick-in space of said pilot probe, said stick-in space of said pilot probe defines a clamp fastening location on said balloon disposed at approximately half the length of the balloon.

3. The probe means as set forth in claim 2, wherein

said stick-in space is formed as a slot in said pilot probe,

said loop is clamped in the slot.

4. The probe means as set forth in claim 3, wherein

said slot extends completely through said pilot probe and said balloon wall extends through said slot such that said loop extends outside said pilot probe.

5. The probe means according to claim 1, wherein

said balloon has a wall,

said pilot probe has a terminal clamping cap means for clamping of said wall of said ballon and releasing said wall of said balloon upon a partial filling of said balloon.

6. The probe means according to claim 1, wherein

said pilot probe defines an insertion side end formed with a plug-in space,

a portion of said balloon is removeably disposed in said plug-in space.

7. The probe means according to claim 1, wherein

said pilot probe is arranged inside of said probe tube.

8. The probe means as set forth in claim 1, wherein

said pilot probe holds said balloon at a fastening location on one side of said pilot probe,

said balloon has two balloon wall sections which are folded together lying on the opposite side of said pilot probe and said fastening location, and

said emptying means includes a collar holding said two balloon wall sections folded together, said collar being slidable off said balloon wall sections by a predetermined inner filling pressure in said balloon.

9. The probe means as set forth in claim 1, wherein

said pilot probe grasps said balloon in an unfilled condition thereof during insertion together of said pilot probe and said balloon.

10. The probe means as set forth in claim 1, wherein

said probe tube including said insertion end has a substantially smaller cross-section than that of said pilot probe.

11. The probe means as set forth in claim 1, wherein

said balloon is adapted for being transported to a target site in a filled condition thereof by peristalsis after the complete separation from said pilot probe,

said emptying means includes,

closure means for holding said balloon closed until a predetermined inner filling pressure occurs in said balloon at the target site.

12. The probe means as set forth in claim 11, wherein

said end of said balloon is open.

13. The probe means as set forth in claim 1, wherein

said pilot probe is formed as a hollow tube.

14. The probe means according to claim 13, wherein

said pilot probe defines an insertion side end,

a coupling connection of said probe tube to said pilot probe adjacent said insertion side end,

pulling means for decoupling said coupling connection,

said pulling means is contained in said pilot probe and extends therein up to said insertion side end.

15. A probe means, particularly for enteral feeding of living creatures extending from the outside in an inserted condition in the creatures, comprising

a probe tube defining an insertion end,

a pilot probe adjacent to said probe tube,

a balloon constituting a probe tube end being coordinated to said insertion end of said probe tube, said balloon being adapted to be filled with liquid,

means for emptying said balloon in an inserted condition,

means for securing said probe tube end on said pilot probe detachable from the outside,

said securing means defines a connection position on one side of said pilot probe,

said balloon has balloon wall sections lying on the opposite side of said pilot probe and said connection position,

said emptying means includes closure means for holding said balloon wall sections together, said closure means for removing from said balloon wall sections by a predetermined inner pressure in said balloon.

16. The probe means according to claim 15, wherein

said closure means constitutes a collar means for stripping off from said balloon wall sections by said predetermined inner pressure in said balloon.

17. The probe means according to claim 16, wherein

said collar means combines said balloon wall sections in a folded-over condition.

18. The probe means as set forth in claim 15, wherein

said balloon has an open end at an end of one of said wall sections.
