A catheter is provided that has at least one lumen which extends from a
proximal end of the catheter to a distal end of the catheter. The
catheter also has a catheter hub that has a body with a proximal end, a
distal end, an exterior surface, and defining an interior cavity. The
exterior surface of the body further defines at least one opening. At
least one opening is defined therein the proximal end, and at least one
opening is defined therein the distal end. The catheter also has a means
for measuring and displaying the number of times that the catheter is
injected with an infusate at a pre-determined pressure.
