The Gray (late 1960s/1970s) and Blue (later, generally 1980s) Laerdal Suction Units have been discussed here before. However, I cannot find any reference here to the Jet Suction Unit. This device uses a CFC aerosol can to generate a vacuum. Certainly an interesting concept.
I recently picked up a few of these, and have attached photos. First photo shows a unit in storage condition on the left, ready-for-use on the right. Second photo is a close-up of the aerosol can and the artwork printed there showing intended use. The patent for this device is visible at https://www.google.com/patents/US3665919
As a side note - while the electric LSU's haven't really been discussed here in a few years, there was some confusion on when they actually were introduced. It was submitted for patent in 1968, but this does not necessarily mean it wasn't available before then. https://www.google.com/patents/US3499601 I have a few news articles which mention the device in the late 1960s. The May 1970 ACS "Essential Equipment for Ambulances" article also cites the device. http://www.professionalcarsociety.org/forums/showthread.php?t=4026
