You may want to replace the disposable latex gloves with a couple of pairs of nitrile gloves. The only other thing I can think of that would contain latex is some Bandaids or a tourniquet. YMMV. Unless you are saying the case itself is latex.

I had a volunteer at a Haunted House a couple of years back who wore a latex mask all night. She found out the hard way of her allergy to latex! <img src="/images/graemlins/tongue.gif" alt="" /> Geez, was that poor woman a mess the next day. :
