An aspiration system is disclosed for removing body liquid (e.g. urine or a secretion) discharged by the human body. The aspiration system comprises a body interface device with a liquid sensor, and an aspiration unit coupled to the body interface device. The liquid sensor comprises a temperature sensor and/or a resistance bridge. The aspiration unit includes: a vacuum chamber; a pump for pre-charging the vacuum chamber with a vacuum; a valve coupled between the vacuum chamber and the body interface device; and a control circuit for controlling the valve to apply aspiration suction from the vacuum chamber to the body interface device in response to detection of body liquid at the liquid sensor.

L'invention concerne un système d'aspiration pour enlever un liquide corporel (par exemple de l'urine ou une sécrétion) déchargé par le corps humain. Le système d'aspiration comprend un dispositif d'interface corporelle avec un capteur de liquide, et une unité d'aspiration couplée au dispositif d'interface corporelle. Le capteur de liquide comprend un capteur de température et/ou un pont de résistances. L'unité d'aspiration comprend une chambre à vide ; une pompe pour précharger la chambre à vide avec un vide ; une soupape couplée entre la chambre à vide et le dispositif d'interface corporelle ; et un circuit de commande pour commander la soupape pour appliquer une pression d'aspiration de la chambre à vide au dispositif d'interface corporelle en réponse à la détection d'un liquide corporel au niveau du capteur de liquide.
