NON-INVASIVE MEDICAL PROBE PROVIDED WITH SUCTION CUP

摘要

A non-invasive medical probe for monitoring a patient's condition in particular an intra-uterine device for monitoring fetal condition, comprises a resilient walled suction cup (10; 110) having a peripheral rim (19; 119) for application to a patient's skin, pump means (24; 42; 43) 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 (33, 41) for connection to diagnostic apparatus. One (33) of the electrodes is disposed on a mounting (14; 114) located centrally within the cup to leave a channel (17; 117) to be evacuated by said pump means and the second electrode (14) is disposed externally of the cup adjacent to the cup to provide a second contact in the vicinity of the contact of the first electrode.
