  • Stomach probe
    Patent number: 5718685
    Abstract: A stomach probe has an aspiration tube (1) and a stomach balloon (7) which is to be held, by tensioning of the aspiration tube (1), in contact against the stomach wall (12) surrounding the cardiac orifice (5). The stomach balloon is connected to a pressure control device which is equipped to indicate at least two pressure stages, of which the lower one corresponds to the freely inflated state of the stomach balloon when the tube is untensioned, and the higher one corresponds to the tensioned state of the aspiration tube. The stomach balloon (7) is arranged on the aspiration tube at points which are at a short distance from each other, so that it assumes approximately a torus configuration in the inflated state. It is elastically resilient in the longitudinal direction of the tube.

  • Stomach tube
    Patent number: 5462528
    Abstract: A stomach tube having an inflatable balloon for closing the stomach opening and an indicator for indicating the balloon pressure at first and second predetermined pressure levels. After the stomach tube is inserted, the stomach balloon is inflated without the stomach tube under tension until the lower pressure level is indicated. The stomach tube is then tensioned until the higher pressure level is indicated. A nose stop is used to maintain the stomach tube tension.
