Abstract: A measurement recording device and a method for acquiring patient measurement values and transmitting them to a display and operating unit and/or a central unit. The device including at least one measurement recording sensor for measuring body properties and/or body functions. The measurement recording device can be identified by at least one ID code and cooperates functionally with at least one scanning device for detecting the ID code or ID feature of a patient and/or for detecting the at least one ID code of the measurement recording device, so that an error-reduced assignment or mix-up of the ID code or ID feature of a patient and his measured body property or body function is supported.

Abstract: It is described an Electro Static Discharge protection, wherein diodes are arranged on two electric paths both extending in between two conductors which are connected with input terminals of an ESD sensitive electronic component. Each path comprises two diodes arranged in series and with opposite polarity with respect to each other. At least one of the totally four diodes comprises a different reverse breakdown voltage. The protection circuit is formed integrally with the ESD sensitive electronic component. Due to the serial connection of two diodes in each path the corresponding ESD protection circuit comprises an extremely low capacitance.
