Zingo Local Anesthesia Like Star Trek Hypospray
Zingo, a neat needle-free powder lidocaine delivery system has been announced in the latest issue of Pediatrics.

The device uses compressed gas to accelerate lidocaine particles under the skin. The device produces significant analgesia within one to three minutes.
SF fans will no doubt be thinking about the hypospray, the universal injection tool in the Star Trek universe.
(Dr. McCoy with the original hypospray)
The idea of a hypospray was still pretty new for sf fans in the 1960's. The jet injector gun, upon which the hypospray is based, had really only been in widespread use in 1960, when it was used to beat smallpox. A jet injector gun uses a high-pressure, needle-narrow jet of the injection liquid. It is powered by a gas cylinder or cartridge. Workmen have been accidentally jet-injecting themselves since the 19th century (with grease).
In most of my memories of the original Star Trek series, most of the time, when Dr. McCoy pressed one of these gizmos to someone's neck, they immediately relaxed or fell unconscious. That is, they were feeling no pain. I also think that he held it in the same way as the diagram of the Zingo shown above. (See the more evolved hypospray from Star Trek: The Next Generation.)
