Definitions
- the invention relates to a gastric tube having the features of the preamble of claim 1.
- the supply cannula is superimposed on a lumen in the region of the tampon balloon, which ensures a rapid volume balance between partial areas or partial volumes of the tampon balloon.
- the lumen is arranged such that a channel is formed between the lumen and the supply cannula, which communicates via a plurality of openings with the interior of the tampon balloon, which is arranged on the lumen.
- the interior of the tampon balloon is connected via the channel formed between the supply cannula and the lumen with means for generating the pressure in the Tamponierblase.
- the lumen is thereby maintained by web-like structures or spacers between an outer and inner wall of the probe or the supply cannula of the nasogastric tube.
- a nasogastric tube is therefore much more complicated to manufacture than e.g. common gastric tubes without lumen.
- the invention has for its object to improve a nasogastric tube of the type mentioned in that the lumen, which is located between the supply cannula and the tamponing and is in communication with the interior of the tampon balloon, technically easy to implement and at the same time a sufficiently good volume balance between Partial volumes of Tamponierblase guaranteed.
- the separate molded body is technically easy to manufacture, since it can be prefabricated as a single part.

- By filling with the fluid expands the tampon balloon 3 until it almost completely rests against the wall of the esophagus 28, as seen in Figure 2. This allows the esophagus 28 largely against liquids or solids, which have the tendency to ascend from the stomach area towards the pharynx, seal and thus keep the trachea from disturbing influences.
- Swallowing movements of the patient supplied with the nasogastric tube according to the invention lead to muscle contractions along the esophagus. These cause one or more of several ring-like constrictions of the esophagus, which proceed from the larynx region towards the stomach or run along the esophagus.
- the annular bladder leads to a partial reduction of the outer diameter of the tampon balloon, ie to a local constriction 31 of the tampon balloon 3, which is shown in Figure 1 by a dashed line.
- the shaped body 2 according to the invention provides a lumen 5 which enables a rapid volume exchange between the individual subregions 29, 30 of the tampon balloon 3.
- the surface 6 of the molding 2 according to the invention provides, if necessary, a contact surface for the constricted wall region of the tampon balloon 3.
- the lumen 5 is thus kept free of these external influences and is completely available for volume exchange.
