A feeding tube assembly for insertion and delivery of nutrients into an alimentary canal is disclosed. A method of facilitating the use of the feeding tube with an insufflation device is also disclosed. The feeding tube assembly has a feeding tube with opposite proximal and distal ends, a feeding passage extending between the proximal and distal ends, an outlet proximate the distal end and in fluid communication with the feeding passage, a port at the proximal end and in fluid communication with the outlet; and an air insufflation device fluidly connectable to the port comprising a compressible air bulb having a bulb inlet and a bulb outlet; an inlet check valve at the bulb inlet, an outlet check valve at the bulb outlet, and a relief valve fluidly connected to the bulb outlet.
