The present invention monitors an IV bag injection port and informs the user of prior injections. The present invention employs an object and/or a sealed chamber within a transparent IV fluid bag injection port. In the case of the object, notification of prior use is achieved when the object's or IV fluid's appearance is altered. With respect to the sealed chamber, the chamber's seal is breached to allow fluid to pass between the chamber and the IV bag to change the appearance of the contents of the chamber. Since the injection port and bag walls are at least partially transparent, medical personnel are able to observe the altered appearance of either the object, IV fluid or the sealed chamber.
