Abstract
A non-invasive medical probe for monitoring a patient's condition in particular an intra-uterine device for monitoring fetal condition is featured. The medical probe includes a resilient walled suction cup having a peripheral rim for application to a patent's skin, a pump adapted for connection to the cup for evacuating the cup to adhere the cup to the patient's skin, and a pair of non-invasive skin contact electrodes for connection to diagnostic apparatus. One of the electrodes is disposed on a mounting located centrally within the cup to leave a channel to be evacuated by the pump and the second electrode is disposed externally of the cup adjacent to the cup to provide a second contact in the vicinity of the first electrode.
