ABSORBENT PRODUCT PROVIDED WITH LEAKAGE SENSORS Russian patent published in 2013 - IPC A61F13/42 

FIELD: medicine.

SUBSTANCE: disposable absorbent product able to detect the absence or presence of urine, as well as urine leakage. An absorbent product comprises a substantially liquid-impermeable layer, a liquid-permeable layer and an absorbent core provided between the substantially liquid-impermeable layer and liquid-permeable layer. A number of sensors are integrated into the product across the width thereof and arranged so that the sensors are in the liquid connection with urine discharged by the user. At least one of the sensors comprises a pH indicator. At least one of the sensors is able to indicate the absence or presence of urine and at least one of the sensors is able to indicate the urine leakage. A method for detecting the absence or presence of urine, as well as the urine leakage in the absorbent product provides the urine contact with the absorbent product so that when urine contacts with the above sensor, there is a preset possibility of the leakage and the absence or presence of urine in the absorbent product and of the fact if the urine leakage from the absorbent product occurs that is ensured by inspecting one or more sensors.

EFFECT: providing reduced liquid leakage from the absorbent product due to detecting the near-leakage state, but before the leakage has occurred.
