Patent ID: 8217218

Claim:
A disposable medical probe for detecting a leak of physiological fluid through an opening made in the human body, by operating in conjunction with an electrical detection circuit, comprising the following layers: a support layer, a conductive layer on top of the support layer ( 10 ), the conductive layer comprising first and second conducting electrodes, said first conducting electrode being placed on one side of a longitudinal axis and said second conducting electrode being placed on the opposite side of the longitudinal axis, the conductive layer defining two zones: a proximal zone, the end of which is configured to be connected to said circuit, said proximal zone comprising a proximal part of each of the first and second electrodes, the proximal parts of the first and second electrodes being placed parallel to each other and spaced apart by a distance a distal zone configured to contact a fluid, said distal zone comprising a distal part of each of the first and second electrodes, the distal parts of the first and second electrodes being spaced apart from each other by a gap, said gap being greater than said distance, where the distal zone of the first and second electrodes defines, running from a border, positioned between the proximal zone and the distal zone, to the end of the distal zone, an increase in the gap between the distal parts of the first and second electrodes, followed by a decrease in the gap between the distal parts of the first and second electrodes.
