Abstract

A safety device for blood-, wound secretion- and infusion supplying conduit which leads to a vessel inlet, the safety device comprises a magnet mountable on a conduit, a Reed-relay fixed substantially close to the magnet on a skin of a patient so that when a distance between the Reed-relay and the magnet increases as a result of moving away of the vessel input the Reed-relay is switched, and a device for triggering alarm in response to the switching of the Reed-relay. Also, a system including the vessel, the conduit and the safety device is proposed.

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.

4. A safety device as defined in claim 1, wherein said means include a treatment device which reacts when the distance between said Reed-relay and said magnet is increased, and means for releasing the alarm and interrupting its operation in response to the switching of said Reed-relay.

5. A blood-, wound secretion- and infusion supplying system comprising a blood-, wound secretion- and infusion supplying conduit adapted to lead to an inlet of a vessel;

and safety device including a magnet mounted on said conduit, a Reed-relay fixable on the skin of a patient substantially close to said magnet 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.

6. A blood-, wound secretion- and infusion supplying system as defined in claim 5, wherein said magnet is arranged substantially close to the inlet of said vessel.

7. A blood-, wound secretion- and infusion supplying system as defined in claim 5, wherein said means include monitoring means 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.

8. A blood-, wound secretion- and infusion supplying system as defined in claim 5, wherein said means include a treating device reacts when the distance between said Reed-relay and said magnet is increased, and means for releasing the alarm and interrupting its operation in response to the switching of said Reed-relay.
