    摘要： A fetal probe (10) has an inflatable sac (24) which wedges between the presenting fetal part and maternal tissue to hold a fetal sensor (16) in position. The fetal probe is short enough (10-20cm) to enable insertion with the amniotic membrane intact. A passage (26) extends through the probe to facilitate intrauterine pressure measurements or amniotomy.

    摘要： A remote sensing tonometric catheter apparatus (20) and method for sampling of a fluid or gas property of interest in a hollow internal organ. The tonometric catheter (20) assists in early detection of the problems of stress ulceration and/or intestinal ischemia. The tonometric catheter (20) has one or more sampling chambers (40) for introduction into a hollow internal organ or an area adjacent thereto. The tonometric catheter (20) has an electric sensor (42) for developing a signal indicative of the condition of the organ. Electric sensor (42) is in communication with the sampling chamber (40). The sensor (42) has a conductor (56) coupled therewith for conveying the signal to a location outside the organ such that the condition of the organ may be remotely determined. Preferably, the wall (36) of the sampling chamber (40) is freely permeable to the gas or fluid to be measured by the sensor (42), but is poorly permeable to other gases or fluids which may interfere with the sensor (42). The method is accomplished by introducing the catheter into the organ such that the sampling chamber is disposed at a portion of the wall of the organ. The sampling chamber is left in position at the wall of the organ for a time sufficient to allow the fluid or gas of interest to diffuse into the sampling chamber. The concentration of the fluid or gas of interest is analyzed. The pH of the wall of the organ may be calculated based on the concentration of the fluid or gas property of interest.
