How does Bane eat?

Because we're medical, such things spark great debate. Here are some of the twitter theories, along with added commentary...

1. Through a straw
This is very plausible. Protein shakes filled with nutrients to keep him going, and a straw to fit through the holes in the mask. 

2. PEG Tube
Nursing home patients come in through the ED CONSTANTLY for dislodged tubes, Bane would be in and out of the hospital or doctors office for issues with the tube. A mickey tube would be a valid option but they are even more complicated when they dislodge, requiring a more complicated replacement procedure.  Besides, his armor is pretty tight fitting and with the amount of physical exertion he does, this would not be a comfortable option.He could have some sort of metal stomach with a welded opening that hides conspicuously into his armor? I feel like this is a stretch.

3. TPN
He obviously doesn't have a PICC, we could argue that he has a port, however there is NO WAY this is the answer. TPN could not sustain Bane's gains. Next.

4.  Rectal Feeds
Interesting unorthodox point. Nutrient rich enemas TID??

5. NGT/Dobhoff feedings
 This might work as well, although that a lot of supplies to carry around to keep placing an NG tube on himself. Plus it would be near impossible to thread the tube through the mask, into the nostril and get it to the stomach without it looping back around and coming out the mask again. Besides, if hes going to be drinking through a straw to assist with placement, just forgo the whole thing and go back to the protein shake deal.

6. Snorting protein powder
I mean I guess he really doesn't need his nose for anything right? So errosion and nose bleeds wouldn't be an issue? But is it possible to remove enough of the mask to allow snorting in one nostril whilst still connected elsewhere?

Other Bane Issues:
-What happens when he has a tummy ache and vomits? Does he aspirate? Is this now septic Bane?
-How do we then intubate septic aspirational pneumonia Bane? Would we have to move right to a cric?
-How do we document on the oral care flowsheet? I'm not aware of a checkbox marked "N/A d/t large metal facial apparatus"

If anyone can add anymore insight, it would be greatly appreciated.
