Abstract

The aim of the present invention is to provide a gastric tube comprising an inflatable stopper and a supply cannula that can be introduced into the oesophagus and on which a lumen is superposed in the region of the inflatable stopper. Said lumen is connected to the interior of the inflatable stopper. It is possible to improve the rapid volume equalization between the various regions of the inflatable stopper in such a way that the lumen, which is located between the supply cannula and the inflatable stopper and is connected to the interior of said inflatable stopper, can be produced in a technically simple manner and at the same time provides sufficient volume equalization between partial volumes of the inflatable stopper. This aim is achieved by a gastric probe comprising an inflatable stopper, in which a separate moulding body is mounted on the supply cannula, thereby determining the configuration of the lumen.

Claims (24)

1. Gastric tube (1) with an inflatable stopper (3) and a supply cannula (4) that can be introduced into the oesophagus and on which a lumen (5) is superposed in the region of the inflatable stopper (3), which is connected to the interior (8) of the inflatable stopper (3) and permits a rapid volume equalization between various regions of the inflatable stopper (3), characterized in that a separate molding body (2) is mounted on the supply cannuda (4) in the region of the inflatable stopper which determines the shape of the lumen (5).
2. Gastric tube (1) according to claim 1, characterized in that the molding body (2) has a tubular structure (18), the inner contour of which approximately corresponds to the outer contour of the supply cannula (4).
3. Gastric tube (1) according to at least one of the preceding claims, characterized in that the molding body (2) comprises at least one opening (22), which extends approximately into the longitudinal direction of the molding body (2) over at least 50 to 60%, advantageously up to 80%, of the overall length of the molding body and connects the lumen (5) to the interior (8) of the inflatable stopper (3).
4. Gastric tube (1) according to claim 3, characterized in that the opening (23) extends approximately over the complete length of the molding body (2).
5. Gastric tube (1) according to at least one of the preceding claims, characterized in that the molding body (2) comprises, in the cross-section, several wall elements (20) extending radially, which comprise a surface (22) at their extreme ends (21) which extends approximately transversely to the respective wall element (20).
6. Gastric tube (1) according to at least one of the preceding claims, characterized in that at least one of the wall elements (20) has an approximately T-shaped profile.
7. Gastric tube (1) according to at least one of the preceding claims, characterized in that at least one of the wall elements (20) has an approximately L-shaped profile.
8. Gastric tube according to claim 1 or 2, characterized in that the cross-section of the molding body (2) comprises several wall regions (13) which are supported at the supply cannula (4) of the tube (1) and define, together with it, at least one partial region (15) of the lumen (5).
9. Gastric tube (1) according to claim 8, characterized in that the wall regions (13) extend approximately like a star into the interior of the molding body (2).
10. Gastric tube (1) according to at least one of the preceding claims, characterized in that the molding body (2) comprises a spirally shaped coil (24).
11. Gastric tube (1) according to claim 10, characterized in that an approximately hose-like element is arranged on the coil (24) and comprises several openings distributed across its surface.

14. Gastric tube (1) according to at least one of the preceding claims, characterized in that the lumen (5) is connected, in the region of the axial front side of the molding body (2), to a supply channel (10) via which the inflatable stopper (3) can be filled with a fluid.
15. Gastric tube (1) according to at least one of the preceding claims, characterized in that the molding body (2) consists of PVC, PUR, mixtures of PVC and PUR, mixtures of PUR and polyamides and/or silicone.
16 16. Gastric tube (1) according to at least one of the preceding claims, characterized in that the molding body (2) is manufactured by extruding.

18. Gastric tube (1) according to at least one of the preceding claims, characterized in that the molding body (2) is fixed on the supply cannula (4) basic body by means of a frictional engagement.
19. Gastric tube (1) according to at least one of the preceding claims, characterized in that the molding body (2) is fixed on the supply cannula (4) by means of adhesion.
20. Gastric tube (1) according to at least one of the preceding claims, characterized in that the molding body (2) is fixed on the supply cannula (4) by means of a material connection.
21. Gastric tube (1) according to at least one of the preceding claims, characterized in that the molding body (2) is treated with a solvent at least in sections.
22. Gastric tube (1) according to at least one of the preceding claims, characterized in that the outside diameter of the molding body (2) is approximately between 7 -mm, in particular between 6 - 8 mm.
23. Gastric tube (1) according to at least one of the preceding claims, characterized in that the length of the molding body (2) is approximately between 6 - 12 cm, in particular between 6 - 9 cm.
24. Gastric tube (1) according to at least one of the preceding claims, characterized in that the tube is provided with at least one radiopaque marker.
