摘要

Compression device (100) comprises an additional tube (1) connected to a first pressure sensor (2), a microphone (3), a determination switch (4) and a separate control unit (5, 7). An independent claim is also included for a method for controlling a compression device. Preferred Features: The additional tube is connected to an external blood pressure measuring collar (10) for transferring pressure. The additional tube is a simple blood pressure measuring collar. A signal from the first pressure sensor is sent to the microphone to transfer the pressure value.
