The liquid perception sensor and the body fluids break-through perception device null which uses

摘要

A liquid liquid leakage sensing device which is small enough to be able to respond appropriately to any mounting condition, and is accurate to a caregiver, and a liquid sensing sensor which can be applied to this body and can be used to detect a small body fluid with high sensitivity and can be disposable And The sensor 1 is composed of a water absorbing body 11 made of a porous material material having a high resistance value, and a coating 14 made of an insulating material so that the ends 12a and 13a of the electrodes 12 and 13 are fixed to both sides of the sensor 1 so that the end 11a of the water absorbing body 11 is exposed. A means for judging presence or absence of body fluid leakage by measuring the resistance value of the sensor 1 and a means for performing a notification according to the judgment are provided.
