A funnel can work wonders in times like these. You can't avoid contact with oxygen that way, unfortunately, but I'm not sure other methods are going to be significantly better, and if it's a traditional mead the oxygen exposure probably won't matter much. Other options include siphoning with just a tube. (Fill tube with sanitizer, put one end all the way to the bottom of the bottle you are siphoning out of, make sure the tube has no air bubbles in it and that the other end is lower than bottom of the bottle you are siphoning out of. Let the sanitizer run into a bucket or something, and when the mead starts coming out start filling up your other bottles. Try not to let the mead touch any part of the tube that your hands touch. A narrower tube is definitely better for this -- less waste, less chance of failure getting the siphon started, and more control overall. Slower, true, but for small quantities that shouldn't matter.)
