摘要： 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. The bandage includes a layer of polymer that expands when wetted with blood. The expansion causes a break in continuity of the sensor, or in an alternate embodiment, causes a sensor to cease detecting a target. When the break occurs, the control circuit monitoring the bandage sends a signal that a break has occurred, and a remote monitor then takes appropriate action, such as ceasing therapy, sending an alert, or sounding an alarm. 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.

摘要： A medical fluid infusion system including: a fluid pathway for transporting a pulsatile flow of fluid; a dampening element in communication with the fluid pathway, the dampening element configured to actively dampen pressure fluctuations of the pulsatile flow to smoothen the pulsatile fluid flow, the dampening element operable in any orientation; and a fluid flow sensor disposed along the fluid pathway downstream of the dampening element to measure the flow rate of the smoothened fluid flow.
