Device for detecting moisture, for use with an arrangement for monitoring an access to a patient

A moisture detection system for use with an arrangement for monitoring an access to a patient for an apparatus by which, via a flexible line, a liquid is at least one of fed to the patient via the access or withdrawn from the patient via the access, the moisture detection system comprising:

• a covering configured to be applied to the patient's skin having a flexible substrate material to which an electrically conductive structure comprising printed conductors is applied as a moisture sensor;
• and
• a terminating resistor;
• wherein the electrically conductive structure has a first printed conductor having a first end and a second end, and a second printed conductor having a first end and a second end,
• wherein the first end of the first printed conductor and the first end of the second printed conductor has a first pair of connecting contacts to connect to the arrangement for monitoring the access, and wherein the second end of the first printed conductor and the second end of the second printed conductor has a second pair of connecting contacts to connect to the terminating resistor which is disposed externally to the covering and which is configured not to contact the patient's skin.
