The week following large intestine cancer surgery is the hardest and most painful time for patients and their nurses.  Patients need to continually change their body position to allow for blood circulation and prevent bedsores, yet they are unable to change position without assistance and a great deal of pain.   And any time they do move, they need to deal with numerous tubes from medical devices.  Angel Wings is an inflatable mat which provides cushion for patients changing their body position, and it also features an opening through which tubes can be run, allowing for fewer tangles and less discomfort.
