I think it's pretty neat and you can see how over time that would develop into the standard Starfleet issue.

These types of injections have been available for a long time now, mostly for diabetics.

Yes, it does look a lot like the hypospray in Star Trek

Except that the hypospray in Trek TOS had some pretty amazing capabilities -- it could inject people right through their clothing. In "The Tholian Web," McCoy injected Kirk with triox compound through his spacesuit!

1960: Aaron Ismach invented and patented the Jet Injector medical device which was used for quick mass vaccination for smallpox and other diseases. Ismach was assisted by Dr. Abram Benenson in developing the Jet Injector Gun. The new method met with tremendous success as teams vaccinated large numbers of people at collecting points in the affected countries. The foot operated gun was called the Ped-O-Jet and the electric operated gun was called the Jet Injector Gun.
