Publication number: 20230285651Abstract: An apheresis system may include an assembly for separating a component from a multi-component fluid, a processor, and a memory storing data for processing by the processor. The data, when processed, may cause the processor to run a calibration test on one or more instruments of the assembly and, based the one or more instruments failing the calibration test, calibrate the one or more instruments or lock the apheresis system for non-use. The apheresis system may include a pump configured to generate a calibration pressure at a test port and a pressure sensor configured to sense a pressure at the test port. The calibration test may include comparing the calibration pressure at the test port to the sensed pressure by the pressure sensor at the test port.Type: ApplicationFiled: March 3, 2023Publication date: September 14, 2023Inventors: John PITTINGER, Stephanie Lynne ST.

Publication number: 20230285644Abstract: A method includes receiving, with an apheresis system, data associated with a donor; determining, based on the data associated with a donor, an identification of the donor; receiving, with the apheresis system, data associated with a blood component collection set; receiving, with the apheresis system, data associated with a plasma collection bottle; and performing, with the apheresis system, a plasma donation process based on the identification of the donor, the data associated with the blood component set, and the data associated with the plasma collection bottle. Receiving the data associated with the donor may include scanning, with a scanner, an image. The scanner is disposed on the apheresis system and the image may include one of a one-dimensional barcode or a two-dimensional barcode. The data associated with the donor may be displayed on a user device.Type: ApplicationFiled: March 3, 2023Publication date: September 14, 2023Inventors: John PITTINGER, Justin BROUSSARD, Stephanie Lynne ST.

Publication number: 20230285653Abstract: A method includes detecting a condition including one or more of a change in flow of a fluid and a change in a composition of the fluid, issuing an alarm in response to the condition detected, lowering a flow rate; and attempting to restart process and increase the flow rate. The change in flow may include a change in pressure. The change in flow may be associated with a collapsed vein. The change in flow of the fluid may include detecting that the flow rate has fallen below a threshold. The change in the composition may be associated with a color. The change in the composition may include using a color sensor to detect one or more of a red, a green, and a blue reflection or transmission to detect red blood cells.Type: ApplicationFiled: March 3, 2023Publication date: September 14, 2023Inventors: John PITTINGER, Stephanie Lynne ST. GEORGE, Taylor POLODNA, Bruce ELLINGBOE, Charles L. HAKE, Evan Christopher PROVAN

Publication number: 20230285655Abstract: An apheresis system at least partially defines a chamber and includes centrifuge that is movable between lock and unlock states. The centrifuge includes a base, cover, lock assembly, and latch assembly. The cover engages the base and defines slots. The lock assembly is coupled to the base and rotates between latched and unlatched states. The lock assembly includes tabs and a protrusion. The tabs are in the slots of the cover. The protrusion at least partially defines a receptacle. The latch assembly is coupled to the base and includes a lever and engagement component attached thereto. In the latched state, the protrusion engages the engagement component to reduce or prevent rotation of the lock assembly. In the unlatched state, the lock assembly can rotate. In the lock state, the tabs are at least partially within the slots. In the unlock state, the cover is movable with respect to the base.Type: ApplicationFiled: March 3, 2023Publication date: September 14, 2023Inventors: Charles L. HAKE, Mark E. HILLAM, John PITTINGER, Bruce ELLINGBOE, Peter O'BRIEN, Dennis BEBIE, Hong Duc NGUYEN
