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.

Abstract: A monitor for an extracorporeal therapy access site is disclosed. The monitor includes a bandage atop or adjacent the access site and a sensor for monitoring the bandage.

In another embodiment, connecting wires in a continuity circuit are held apart by a polymer that dissolves when contacted by blood. If a leak occurs and a small portion of the polymer dissolves, the wires make contact, thus detecting a blood leak.

Abstract: Methods and systems for determining whether an implanted catheter used to deliver fluids to a selected internal delivery site is malfunctioning. The malfunctions may include that the infusion section of the catheter is not located at or has migrated away from the selected internal delivery site, is leaking, is blocked, etc. The determination is made by analyzing the pressure modulation of fluid within the catheter and determining whether the pressure of the fluid in the catheter is modulated by physiologic pressure changes experienced at the selected internal delivery site. The physiologic pressure modulations at the selected internal delivery site may be caused by, e.g., cardiac activity, respiration, changes in patient's posture, etc.
