Medical equipment for David

Hi I'm Brenda and I'm trying to raise funds for my brother David for a new airbed. David was in a bad accident years ago and is paralyzed from the chest down. He has developed large bed sores and has been bedridden for more than 5 years. He recently tried an air bed for a month and had more healing in that time than he has had in 5 years. The new bed is quite expensive at 12318.00 his extended health will only cover 3675.00 so we are reaching out for help. Thank you for your support. David is 52 and loves fishing and spending time with his neices and nephews and he hasn't been able to do any of the things he likes for a long time.
