I created something that may help. I've been using it since my accident in 2010. Here's the description:
Paraflush™ is an at home external enema device. This device can be used to stimulate your body's natural reflexes and induce a bowel movement without the need of a suppository or stool softeners. It is cleaner, more effective, and requires less time to complete a bowel program. It also stimulates your digestion when used more than a few times.Specific use directions can be somewhat personal and are included.
