摘要： A sensor device for identifying an ostomy effluent leak location in an ostomy system includes a stoma opening and electrically conductive circuitry arranged in pattern around the stoma opening. The electrically conductive circuitry includes a first electrode and a second electrode spaced from the first electrode. The first electrode is subdivided by a plurality of resistors spaced along a length of the first electrode. The second electrode extends as a continuous strip of conductive material. The sensor device is configured to detect electrical resistance in the electrically conductive circuit and identify a location of a leak based on the detected electrical resistance.

摘要： An ostomy appliance system includes an ostomy appliance having a stoma opening and a first electrical interface, and at least one thermal sensor configured to detect at least one thermal property, such as temperature, at the ostomy appliance, the at least one temperature sensor connected to the first electrical interface with electrical circuitry. A wearable device may be removably connected to the ostomy appliance and operably connected to the at least one thermal sensor. The wearable device includes a housing, a second electrical interface configured for electrical connection to the first electrical interface, a power supply and a controller operably connected to the power supply. The controller is configured to determine a condition of the ostomy appliance based on the at least one thermal property detected at the at least one thermal sensor. The wearable device may also include a wireless transceiver configured to communicate with a personal communication device.

摘要： An ostomy appliance includes an ostomy hydrocolloid having a body-facing side, a pouch-facing side and a stoma opening, at least one fluid aperture formed in the body-facing side and at least one fluidic channel embedded in the ostomy hydrocolloid having a proximal portion disposed in fluid communication with the at least one fluid aperture. The ostomy appliance also includes at least one window formed in the pouch facing side, the at least one window aligned with a distal portion of the fluidic channel such that a portion of the fluidic channel is visible through the window. In another embodiment, an ostomy appliance includes a skin barrier material and an ultrasonic detection device for monitoring the skin barrier material.

摘要： A method of detecting ostomy effluent leakage in an ostomy appliance is provided. The method includes the steps of providing a plurality of sensors; measuring resistance of the ostomy appliance using each of the plurality of sensors; entering resistance measurements in a ring buffer configured to hold resistance measurements; calculating a median resistance value of each of the plurality of sensors using the resistance measurements; comparing the median resistance value against a predetermined range of acceptable resistance values; increasing a leak count for a corresponding sensor when the median resistance value of the sensor is outside the predetermined range of acceptable resistance values; determining a leak state when the leak count increases beyond a predetermined acceptable leak count; and sending an alert upon a determination of a leak state.
