Waterproof HA for Tube Dranage

Is there a Hearing Aid that has a waterproof speaker? I wear an over the ear HA. I have a tube in my right ear for drainage, the same as some kids have tubes put in. The drainage shorts out the speaker so the over the ear hearing aid is useless; the rest of the HA works fine, but you cant use it without the speaker. Is there a Hearing Aid that has a waterproof speaker? Thanks!
