The invention relates to a vein compressing device comprising a pressure hose cuff and a pressure source as well as a pressure adjusting auxiliary means for detecting and/or adjusting the internal pressure of the cuff to a predetermined value. This pressure value causes a compressive force to act via the pressure hose cuff on the upper arm of a patient to be treated, the compressive force being large enough to cause a squeezing off of a vein while the flow area of an artery is maintained at least partly.
