While the invention has been illustrated and described as embodied in a safety device for blood-, wound secretion- or infusion supplying conduit, and blood-, wound secretion or infusion supply system provided therewith, it is not intended to be limited to the details shown, since various modifications and structural changes may be made without departing in any way from the spirit of the present invention.
Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can, by applying current knowledge, readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention.
What is claimed as new and desired to be protected by Letters Patent is set forth in the appended claims:
 1. A safety device for blood-, wound secretion and infusion supplying conduit which leads to a vessel inlet, the safety device comprising a magnet mountable on a conduit; a Reed-relay fixable substantially close to said magnet on a skin of a patient so that when a distance between said Reed-relay and said magnet increases as a result of moving away of the vessel inlet said Reed-relay is switched; and means for triggering alarm in response to the switching of said Reed-relay.
2. A safety device as defined in claim 1, wherein said magnet is arranged substantially close to the vessel inlet.
3. A safety device as defined in claim 1, wherein said means include monitoring means which monitors the distance between said Reed-relay and said magnet, and means for releasing the alarm in response to the switching of said Reed-relay.

English

### Assessment ###
The text describes a safety device using a magnet and Reed-relay, so we could ask about what triggers the alarm in this system.

### Query ###
What activates the alarm in a magnetic medical safety device?

Note: This is a straightforward question that someone might naturally ask without knowing about the source text, yet the text contains the clear answer (the increasing distance between Reed-relay and magnet triggers the alarm).
