ABSORBENT ARTICLE COMPRISING MOISTURE DETECTOR Russian patent published in 2016 - IPC A61F13/42 

FIELD: personal use articles.

SUBSTANCE: absorbent article comprises an electrically-insulating bottom sheet, a sensor of fluid ejection, having an absorbent core on the bottom sheet side facing the body on the lower side of the bottom sheet and a hole through the bottom sheet, providing the communication of the sensor of fluid ejection with the absorbent core, so that the sensor of fluid ejection detects the changed electrical properties when a part of the absorbent core connected to the sensor of fluid ejection through the hole passes from the dry state to the wet state. And the sensor of fluid ejection is provided by electrically conductive material which is partially communicated to the absorbent core through the hole. There is a plurality of electrically conductive lines forming the sensor of fluid ejection, and each of these lines is partially exposed through the holes, and the sensor of fluid ejection is located on the bearing sheet or the substrate. And in the bottom sheet there is a plurality of holes, at that each hole exposes an underlying for the absorbent core electrically conductive part of the sensor of fluid ejection. The plurality of holes is spaced apart from each other in the longitudinal direction. And the longitudinal axis extends in the front-rear direction of the absorbent article.

EFFECT: improvement of efficiency of use of the article.
