  • a printed sensor for wearing on the skin is known from the European patent EP 2 305 108 B1. Such measurement purposes can be explained using the example of a dialysis machine.
  • dialysis In the context of dialysis - without being restricted to a certain form of dialysis here - it can be desirable or necessary to record certain parameters by measurement. For example, values relating to the current condition of the patient as well as values relating to functional values of the dialysis can be recorded. For example, pulse, blood pressure values (systolic, diastolic), oxygen saturation, etc. can be recorded as examples of non-invasive recordable values. Weights, quantities, pressures, pH values, creatinine values, etc. of liquids in connection with dialysis can also be recorded.
  • sensors were provided on the respective devices for dialysis-specific values. However, it must be ensured that hygienic requirements are met. This can happen on the one hand that the corresponding sensors for disinfection are accessible after each patient, or on the other hand that such a disinfection is not necessary due to a corresponding design of the sensors.
  • the disinfection of parts of a dialysis machine after each patient is very time-consuming. In the past, this expenditure of time has repeatedly led to hygiene requirements being reduced to the detriment of the patient.
  • sensors have therefore been developed that no longer come into direct contact with elements that would otherwise have to be disinfected. For example, this can be achieved by attaching pressure sensors from the outside to flexible elements through which fluids flow.
