Blood processing method using a centrifuge for photopheresis
The patent US12064544B2 outlines a method for operating a blood processing system that includes a centrifuge designed to separate blood into distinct layers: plasma, buffy coat, and red blood cells. The method involves introducing blood through a first port into the centrifuge, where it is then rotated to facilitate separation. Key steps include monitoring the interface between the buffy coat and red blood cell layers, as well as assessing specific conditions related to the volume of blood processed. The system directs fluid flow from a second port into a container, specifically extracting the buffy coat when certain conditions are met, such as the volume of blood being less than or greater than a predetermined target.
Further enhancements to the method include additional monitoring steps to assess hematocrit levels in the fluid flow, which can influence the continuation or suspension of the fluid flow process. The system is designed to utilize a disposable kit that includes the centrifuge and container, and it incorporates user input for activating a blood prime function. This function allows for the introduction of donor blood before patient blood, with safeguards in place to prevent the transfer of contents back to the patient during specific operational phases. The method also includes provisions for photo therapy of the collected blood, ensuring that the system operates efficiently and safely throughout the blood processing procedure.
