You need to let her system come back from the regurge so like it's been said....wait two full weeks and then offer a much smaller than normal prey item. Gradually work her back up to her normal (not oversized prey item) over a number of feedings and no further regurges.

I'd be getting that bandaid off her. Soak to loosen it completely then just snip it off so it doesn't pull at her scales.

For the bite/cut make sure it's clean, dab on triple antibiotic without pain reliever and then keep her on layers of plain white paper towels rather than loose bedding that could stick to the wound.

Since she's had a bite or an injury, likely wasn't kept very well and has recently regurged I think it's probably wise to have a vet take a look at her. The regurge may have been due to a too large prey item, it also may have been due to being hauled from his place to yours immediately after eating, or it could be due to a health issue. Only you and your vet can end up determining that really.
