Last week I was lucky enough to score a near mint condition copy of a hospital and doctor's supply catalog from 1922.

Here's a page of patient restraints, including prices. There's no doubt gear like this could be cruelly misused, but the devices seem genuinely humane. The restraint sheet is a far cry from the infamous "Utica Crib" that was used at the New York State Lunatic Asylum just down the road from my home. Click through for the high resolution version.
