    摘要： An apparatus is disclosed for detecting moisture, which is intended for the use in an apparatus for monitoring an access to a patient for a device by means of which a fluid is conducted to and/or removed from a patient via a hose line, in particular for monitoring the vascular access during an extracorporeal blood treatment, wherein blood of a patient is removed from the patient via an arterial hose line, which has an arterial puncture cannula, and is conducted back to the patient via a venous hose line, which has a venous puncture cannula. The apparatus for detecting moisture is designed as a pad which is made of a flexible material and is to be applied onto the patient's skin and which comprises an upper side facing away from the patient's skin and a lower side facing the patient's skin. The pad comprises an opening for the passage of fluid, in particular blood, and a moisture sensor having contact elements for the connection of the same. The moisture sensor is capable of detecting blood flowing through the opening to the surface of the pad. The apparatus according to the invention is characterized in that the lower side of the pad is impervious to fluid.
