    • 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.
    • 胃探针具有吸引管(1)和胃气囊(7),其通过吸引管(1)的张紧而与围绕心脏孔(5)的胃壁(12)接触而被保持。 胃气球连接到压力控制装置,该压力控制装置被配备为指示至少两个压力级,其中下压力级对应于当未拉伸管时胃气球的自由膨胀状态,并且较高的压力级对应于张紧的 抽吸管的状态。 胃气囊(7)在彼此相距很短距离的点处布置在抽吸管上,使得其在充气状态下呈现大致圆环构型。 它在管的纵向具有弹性弹性。
