  • the liquid detection device 10 can also be used for pets 94 such as dogs and cats.
  • pets 94 such as dogs and cats.
  • a body fluid treatment article 96 such as a disposable diaper or a body fluid treatment pad is worn.
  • the pet animal 94 has active movement of the lower body, and when it moves in the room with the body fluid treatment article 96 worn, the body fluid treatment article 96 may be detached from the body due to the movement.
  • the body fluid treatment article 96 when the body fluid treatment article 96 is covered with the clothes 97, it cannot be notified to the outside that the excrement has been excreted due to the smell of excrement, and the excrement adheres to the skin of the pet 94 for a long time. It also caused rashes and rashes.
  • the sensor structure 16 is arranged on the inner surface of the body fluid treatment article 96 located inside the clothing to sense the excretion thereof, and is quickly excreted to the outside by the notification device 18. Therefore, the bodily fluid treatment article 96 can be replaced at an early stage, and there is no possibility that such a disadvantage will occur.

Abstract

Le dispositif de détection d'un liquide ci-décrit permet de détecter de manière fiable une fuite de liquide ou autre et de la signaler à l'extérieur à l'aide d'une conception simple ne nécessitant pas la fourniture d'une alimentation depuis l'extérieur, et dont l'installation et le remplacement des éléments constitutifs sont relativement simples. Un connecteur (17) comprend un premier connecteur (19A) comportant une paire de premières bornes de connexion (41a, 41b) reliées à une électrode de cellule à eau (21), et un second connecteur (19B) comportant une paire de secondes bornes de connexion (48a, 48b) reliées à une électrode de dispositif rapporteur (18). Le premier connecteur (19A) et le second connecteur (9B) sont raccordés de manière amovible l'un à l'autre, et les premières bornes de connexion (41a, 41b) et les secondes bornes de connexion (48a, 48a, 48b) sont électriquement connectées.
