Security device for blood vessel accesses for carrying blood, wound discharge, nutrients or infusions

摘要

In this security device, a magnet (1) is fitted on the tube of a cannula or catheter and a reed relay (2) is fixed independently thereof such that the magnet (1) moves away from the reed relay (2) when the vessel access slips out of the vessel, so that a monitoring unit (3) is warned thereby or a treatment device (3) is brought to a standstill. <IMAGE>
