1. An apparatus for detecting unintentional urination by a user of the apparatus comprising:

  • an elongated belt;

    elongated urine sensing pad means including first and second separated electrodes which form a portion of an electrical circuit path, the conductivity of the portion of the circuit path between the electrodes increasing upon the presence of urine between the electrodes;

    attachment means for detachably securing the pad means to the belt with the pad means disposed adjacent the groin area of the user for the reception of urine from the user, the attachment means including a first section of hook and eye fabric means mounted to said belt means, a second section of hook and eye fabric means mounted to an upper end of said pad means and cooperatively engaging the first section of hook and eye fabric means to detachably secure the pad means to the belt, first and second spaced apart electrically conductive snap fastener means mounted to the belt and projecting through the first section of hook and eye fabric means, and third and fourth spaced apart electrically conductive snap fastener means mounted to an upper end portion of said pad means and each in electrical contact with respective one of the first and second electrodes, the third fastener means engaging the first fastener means and the fourth fastener means engaging the second fastener means to detachably secure the pad means to the belt; and

    electrical circuit means carried by the belt and coupled to the first and second fastener means such that the electrodes are coupled to said electrical circuit means when the first and second fastener means engage the respective third and fourth fastener means, said electrical circuit means comprising means for sensing and indicating the increase in conductivity between the first and second electrodes upon the presence of urine between the electrodes.
