hypospray

But the idea of a hypospray is no longer merely fiction.

In 2012, MIT released an updated design for the "hypospray" which can be programmed for many uses, and inject drugs at the speed of sound, which they hope will eventually eliminate the need for needles.

His "gun" was a Hypospray injector made by Detroit's R. P. Scherer Corp., modified to meet Dr. Anderson's suggestions.

The Hypospray, first offered to doctors in 1947, has found few takers outside the Navy.

The hypospray blasts a drug through the pores, using air pressure of 25 to 125 pounds per square inch.
