Somnetic inducer
A somnetic inducer was a medical device that could be used if a patient suffered from insomnia. The somnetic inducer was put next to the bed of the patient and would help him fall asleep.

When Geordi La Forge suffered from sleeplessness due to brainwashing by Romulans in 2367, he came to sickbay and Doctor Beverly Crusher gave him a somnetic inducer to help him sleep. ()
