Transfusion system 100 is in safety zone, without being moved.If indicating module 5 shows that the size of magnetic field strength is 50mT, and
User thinks that critical magnetic field strength is 40mT at this time, and therefore, transfusion system 100 has been in danger zone at this time, then needing will be defeated
Liquid system 100 is far from magnetic resonance equipment.
When indicating module 5 is by showing size of the different colors to indicate magnetic field strength, the indicating module 5 includes
The indicator light of three kinds of colors indicates the size of magnetic field strength.And when magnetic field strength is less than critical magnetic field strength, indicate mould
Block 5 can also show the first color；When magnetic field strength is equal to critical magnetic field strength, indicating module 5 can also show second of face
Color；When magnetic field strength is greater than critical magnetic field strength, indicating module 5 can also show the third color.The critical magnetic field strength
For 20-40mT.
For example: indicating module 5 includes the indicator light of green, yellow, red three kinds of colors.Magnetic field detection module 4 can will test
To magnetic field strength information be sent to indicating module 5, when the magnetic field strength detected is less than 20mT, indicating module 5 can brilliant green
Lamp represents transfusion system 100 and is in safety zone；When the magnetic field strength detected is 20-40mT (for example, 25mT, 30mT
Or 40mT) when, the bright orange lamp of the meeting of indicating module 5 represents transfusion system 100 and is in critical zone；When the magnetic field strength detected
Greater than 40mT, indicating module 5 can send out a warning, and represent transfusion system 100 and be in danger zone, need transfusion system 100
Dislocation safety zone.
