Abstract

See full text

Blood component processing systems and methods are coupled to a blood component processing device. The systems and methods include a fluid circuit that comprises at least one fluid pressure actuated pump station, at least one fluid flow path communicating with the pump station, and at least one valve in the fluid flow path. A control module is sized and configured to interact with the fluid circuit. The control module includes an actuator to selectively apply fluid pressure to the pump station in concert with operation of the valve to pump fluid through the fluid flow path in response to a control program. A controller coupled to the control module includes the control program and a fluid circuit integrity test function. The fluid circuit integrity test function commands the control module to selectively apply fluid pressure to the pump station in concert with operation of the valve to introduce a fluid within a region of the fluid circuit and to confine the fluid within the region while applying fluid pressure to the pump chamber. The fluid circuit integrity test function generates an integrity output in response to sensing leakage of fluid from the region.
