Thanks for the pictures -unfortunately, it is hard to see what's really going on under the feathers. If you could clip a few of the feathers, and post a few more pictures that would be great.
Normally with bite wounds, you'll see significant green discoloration on the skin which is simply brusing; if you are witnessing necrosis (blackness) it is possible there is a lack of blood flow to the area due to the injury - in that case, the wing may need an amputated. If the blackness is merely superficial, it's likely you're seeing dried blood.
If you have already flushed the wound well, I would simply continue applying the ointment you have daily. If it were mine, I'd start her on antibiotics - you can find some here.

Monitor the bird's water intake, and ensure she's eating enough. Weighing the bird on a gram scale is a great way to determine whether supplemental tube feeding will be needed.
