Patent ID: 8288607

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, 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; and a hydrophilic layer, configured to receive a physiological fluid, said hydrophilic layer being configured on top of at least a part of the conductive layer, where the conductive layer defines the following zones: a proximal zone, the end of which is configured to be connected to said electrical 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, and a distal zone configured to contact the physiological 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 symmetrical with respect to said longitudinal axis and being spaced apart from each other by a gap, said gap being greater than said distance, wherein the hydrophilic layer covers only the distal zone of the conductive layer.
