A pulsatile fluid pump system includes a pump-valving assembly including a chamber and a diaphragm assembly coupled to the chamber and including a flexible diaphragm. The diaphragm assembly and the pump-valving assembly are configured as an integral pump assembly. The system further includes a linear motor having a magnet and a coil, the magnet moving in relation to the coil, the coil having an electrical input. The system also includes a control housing rigidly coupled to the linear motor and a controller system having an electrical output coupled to the electrical input of the coil, the controller system defining an electrical waveform at the electrical output to cause desired operation of the diaphragm. The integral pump assembly is configured to be removably coupled to the control housing, and the diaphragm assembly of the integral pump assembly is configured to be removably coupled to the linear motor.

A continuous flow centrifuge bowl includes a rotatable outer body, and a top and bottom core that are rotatable with the outer body. The bottom core has a wall extending proximally from a bottom wall. The proximally extending wall is radially outward from at least a portion of the top core and, together with the top core, defines a primary separation region in which initial separation of the whole blood occurs. The bowl may also have a secondary separation region located between the top core and the outer body, and a rotary seal that couples an inlet port and two outlet ports to the outer body. The inlet port may be connected to an inlet tube that extends distally into a whole blood introduction region. Additionally, one of the outlet ports may be connected to an extraction tube that extends into a region below the bottom core.

An apparatus for measuring pressure within a fluid path includes a housing defining the structure of the apparatus. The housing includes a fluid path that extends through the housing and allows a fluid to pass through the housing. The apparatus also includes a first volume chamber that is in fluid communication with the fluid path and has a first volume chamber opening, and a second volume chamber with a second volume chamber opening that is less than the first volume chamber opening. A diaphragm separates the first volume chamber from the second volume chamber and fluidly disconnects the second volume chamber from the fluid path. The diaphragm deforms based upon the pressure within the fluid path. The apparatus also includes an interface that is connectable to a pressure sensor, and the second volume chamber is in fluid communication with the interface.

A top for a plasma storage container includes a top body that defines the structure of the top and seals an opening of the plasma storage container. The top also includes a first opening and a vent opening extending through the top body. A valve mechanism is located at least partially within the top body and includes an aperture therethrough. The aperture opens upon connection of a blunt cannula to provide access to the interior of the plasma storage container. The top also includes a vent filter. The vent filter allows air to vent through the vent opening during plasma collection.

A diaphragm assembly for a pulsatile fluid pump includes an edge-mounted flexible diaphragm, the diaphragm configured for operation cyclically between a diastole mode and a systole mode. The diaphragm assembly further includes a systolic distribution brace having an interior wall configured to cup a portion of the outside surface of the diaphragm, and a diastolic plate, embedded in the diaphragm, mechanically coupled to a portion of the inside surface of the diaphragm. In the course of the systole mode, force is applied across the maximum radial extent of the systolic distribution brace, so as to impart tension in the diaphragm around the periphery of the systolic distribution brace. In the course of the diastole mode, force is applied across the maximum radial extent of the diastolic plate, so as to impart tension in the diaphragm around the diastolic plate.

A pump-valving assembly for a pulsatile fluid pump includes a pumping chamber, an inlet port, and an outlet port. The pump-valving assembly further includes an inlet ball check-valve assembly, first and second tapered tracts disposed between the inlet port and the pumping chamber, an outlet ball check-valve assembly, and third and fourth tapered tracts disposed between the pumping chamber and outlet port. The first tapered tract expands in cross sectional area from the inlet port to the inlet ball check valve assembly, and the second tapered tract decreases in cross sectional area from the inlet ball check valve assembly to the chamber. The third tapered tract expands in cross sectional area from the chamber to the outlet ball check valve assembly and the fourth tapered tract decreases in cross sectional area from the outlet ball check valve assembly to the outlet port.

A pulsatile fluid pump system for driving a fluid pump assembly includes a reciprocating linear motor having a magnet and a coil, the magnet moving in relation to the coil, the coil having an electrical input. The pulsatile fluid pump system further includes a controller system having an electrical output coupled to the electrical input of the coil, and the controller system is configured to execute a waveform program defining an electrical waveform at the electrical output. The waveform program is configured to control operation of the linear motor by modification of a feature, selected from the group consisting of amplitude, frequency, shape, and combinations thereof, of the electrical waveform at the electrical output. The waveform program is further configured to accept a set of user-specifiable parameters defining the performance of the linear motor and to modify the electrical waveform in response to such parameters.

A flow through fluid sampling system includes a sample tube and a cap. The sample tube is configured to collect a sample of a fluid and has an open top. The cap is configured to be secured to the sample tube to close the open top. The cap includes an inflow port configured to allow fluid to enter the fluid sample tube, an outflow port configured to allow fluid to leave the sample tube.

A method for washing platelets includes introducing anticoagulant into a platelet product container, drawing re-anticoagulated platelet product from the platelet product container, and introducing it into a centrifuge bowl. The centrifuge bowl separates the platelets from the supernatant in which they are suspended. The method then washes the platelets by introducing wash solution into the centrifuge bowl. As the wash solution is introduced into the bowl, it displaces the supernatant from the bowl and into a waste container. The method then introduces platelet additive solution into the centrifuge bowl, which displaces the wash solution from the centrifuge bowl and into the waste container and further wash the platelets. The method then repeatedly accelerates and decelerates the centrifuge bowl to resuspend the platelets in the platelet additive solution.
