Technically, he did not?
Hmm, I thought the units were always cc (volume), but apparently in VOY/ENT, it was mg (mass).
If that doesn’t work, it’s straight to reprogrammed Borg nanoprobes.
What’s wrong with a little assimilation, as a treat?
In universe it’s supposed to like strengthen cell membranes.
Since a lot of issues stem from cell membranes being pierced, damaged, etc. that should be fairly generally effective. Especially as a first step to try against an unknown.
Technically it’s just a targ dewormer.
It turns out that removing targ worms drastically increases your odds of surviving most afflictions and ailments, so it’s a standard practice for the EMH mk I for every issue.
The EMH mk II discontinued this practice but most crew members find him off putting and avoid him.
So how do the hyposprays work? Does it have a tiny replicator to produce the serum?
IIRC, there are quite a few episodes of Voyager showing the hypospray being loaded/reloaded with a cartridge. It’s unclear how many doses are contained in the cartridge, but typically more than one. I would think that for most treatments the Sickbay replicator just produces a ready-to-use batch of cartridges, whereas for more specialised medication the EMH has to actually make it up manually.
that shit amazin fam
