In reply to BusyLizzie:
i use finger tape for the odd cut i get outside,
but medical glue might be a good option.
Medical Glue
2-octyl cyanoacrylate (Derma+flex® QS™, SurgiSeal, FloraSeal and Dermabond) causes less skin irritation and increased flexibility and strength compared to traditional 'Super Glue'. In 1998 the US FDA approved 2-octyl cyanoacrylate for the closure of wounds and surgical incision and in 2001 was approved as "barrier against common bacterial microbes including certain staphylococci, pseudomonads, and Escherichia coli".
n-butyl cyanoacrylate wound adhesives are available under the trade names: LiquiBand®, Histoacryl, Indermil, GluStitch, GluShield, and Periacryl (dental adhesive)
Octyl ester, while providing a weaker bond, are more flexible. Butyl esters provide stronger bond, but are rigid.
A cheaper alternative...Veterinary Glues
If you are looking for something for your personal first aid kit and don't fancy spending £120 on 6 x 5ml vials of Derma Bond, veterinary glues are commercially available as a happy compromise; not licensed for use on humans but essentially the same stuff in a different wrapper.
