A method and a device for folding a cover material on a medical sensor having a carrier material which is to be fixed to the skin of a patient and which, on the side facing the patient, is provided with an adhesion or adhesive layer to which the cover material is applied, wherein a section of the cover material which is opposite an adhesion-layer-free section of the carrier material forms a tab. The method and the device are based on the use of a tool for folding the cover material which has at least two contact surfaces which intersect at an edge which runs parallel to the plane of the combination of carrier material and cover material. The tool is moved on an axis which runs at an angle to the plane of the combination of carrier material and cover material in such a way that the tab is gripped by the tool and folded over by the tool. After the tab has been folded over, pressure is applied to the folded-over section of the carrier material to produce a folded edge.

Method and device for folding a cover on a medical sensor

A method and device for testing sensors to be applied on a patient's skin for detection of liquid or moisture are described, in particular for monitoring vascular access in an extracorporeal blood treatment, in which a patient's blood is carried away from the patient via an arterial line and is fed to the patient via a venous line. A method for producing sensors to be applied on a patient's skin for detection of liquid or moisture is also described. The method and device according to the present invention are based on the testing of one or more moisture sensors which are taken from current production. The method includes providing a large number of twists of the moisture sensor applied onto a torsion body, the mechanical stresses thus recreating the stresses that can occur in practice when the moisture sensor is applied or stuck onto the patient's skin or forearm.
