This Demin straight jacket is from the Lakehead Psychiatric Hospital in the 1930’s.  Straightjackets have long sleeves and were used to restrain those who could do harm to themselves or to others.  The straightjacket is described in a book by David Macbride in 1772 but others claim it was invented by Guilleret in 1790 and was called camisole de force.
