Abstract: The present invention relates to a method for recovering raw materials (i.e. of polyols and optionally additionally amines) from polyurethane foams, comprising chemolysis. The chemolysis is characterised in that a polyurethane foam is reacted with an alcohol and water in the presence of a catalyst at a temperature of between 130° C. and 195° C., the mass ratio of (total) alcohol and (total) water to the polyurethane foam [i.e. m(alcohol+water)/m(polyurethane foam), where “m”=mass] being between 0.5 and 2.5, and the mass of the water being between 4.0% and 10% of the mass of the alcohol. The catalyst comprises a metal salt selected from a carbonate, a hydrogen carbonate, an orthophosphate, a monohydrogen orthophosphate, a metaphosphate or a mixture of two or more of said metal salts.

Abstract: A management method for outpatient electrocardiography on a patient using an ECG recorder, an administration network, a first mobile device and at least one second mobile device is provided. In order to initialize outpatient electrocardiography on a patient, the first mobile device is connected to the ECG recorder and to the administration network and in the process an identification code assigned to the ECG recorder is transmitted from the ECG recorder to the administration network. After the verification of the authorizations of the mobile device, at least one certificate assigned to the ECG recorder is provided by the administration network and is transmitted to the ECG recorder for storage via the mobile device. The second mobile device is connected to the ECG recorder and to the administration network and in the process the identification code assigned to the ECG recorder is transmitted from the ECG recorder to the administration network.

Abstract: The invention relates to an assembly for providing a long-term ECG. The assembly comprises a portable ECG device (1), which is designed and intended to record, for a defined or definable time period, an ECG of a patient who can be associated with the ECG device (1), and an application software (2) for the ECG device (1) that can be executed on a mobile device (3) or on a computer. By means of the application software (2), parameters of the ECG device (1) can be set and data recorded by the ECG device (1) can be read out and displayed. Furthermore, the application software (2) is designed to visually instruct an operating person in the electrode placement for an ECG and to detect and evaluate parameters of the ECG device (1) and/or of an ECG cable (41-43) connected to the ECG device (1).
