My Father PBP and has had a Feeding tube for several months. He recently lost mobility in his left hand so I designed and patented an apperatus to allow him to continue to feed himself. I have several of them in production and taking orders. Follow the link to see a picture and more information.
When I no longer have the use of my hands I will either have a carer push bolus feed me , or go back to the drip pump feeding method .
I don't know how much your product costs but surely if it's dificult to hold the gravity syringe feed up , it would need dexterity to load the syringe and connect tubing .
