Patent Images
1. A measuring device comprising:
- at least one sensor, wherein the measuring device can be placed on skin surface of a patient for detecting a measured value by means of the sensor;
at least one first contact surface on an underside of the measuring device;
at least one second contact surface on the underside (24) of the measuring device, which said underside is intended for being in contact with the skin surface of the patient; and
a detecting means for detecting a measuring current resulting from a particular effective electric resistance between the at least one first contact surface and second contact surface.

Abstract
A measuring device (10) has at least one sensor (16, 18), which can be applied to the skin surface (12) of a patient for detecting a measured value with the sensor (16, 18). The device (10) has two contact surfaces (20, 22) on an underside (24), which is intended for being in contact with the skin surface (12) of the patient. A current detecting (32, 34), detects a measuring current (30) resulting from a particular effective electric resistance between the contact surfaces (20, 22). A method for operating such a measuring device (10) and a system with such a measuring device (10) are also provided.

12. A system comprising:
-
a medical device; and at least one measuring device connected to the medical device by means of a first feed line and a second feed line, the measuring device comprising; at least one sensor, wherein the measuring device can be placed on skin surface of a patient for detecting a measured value by means of the sensor; at least one first contact surface on an underside of the measuring device; at least one second contact surface on the underside of the measuring device, which said underside is intended for being in contact with the skin surface of the patient; and a detecting means for detecting a measuring current resulting from a particular effective electric resistance between the at least one first contact surface and second contact surface, wherein a feed current is fed to the measuring device by means of the medical device alternatingly via the first and second feed lines, and a measuring current which can be analyzed by means of the medical device during operation, is fed to the medical device by the measuring device via a respective complementary feed line. - View Dependent Claims (13, 14, 15, 16, 17)
