Title: System and method for collecting plasma
Assignee: Haemonetics Corp
Inventor: Michael Ragusa
Filing Date: March 12, 2025
Issue Date: August 5, 2025
Abstract:
A method for collecting plasma includes determining the weight, height, and hematocrit of a donor, and calculating a donor plasma volume and a target plasma collection volume. The target plasma collection volume is based on the donor plasma volume and a target percentage of plasma. The method then withdraws blood from the donor through a line connected to a blood component separation device, and introduces anticoagulant into the withdrawn blood. The blood component separation device separates the blood into a plasma component and a second blood component, and the plasma component is collected from the blood component separation device and into a plasma collection container. The method may then calculate the volume of pure plasma collected within the plasma collection container, and continue processing/collecting until the calculated volume of pure plasma equals the target plasma collection volume.
Plain-Language Overview of Independent Claims
Based on the provided patent text, the independent claims are not explicitly delineated with standard claim numbering (e.g., "1.", "2.", etc.). However, the "Summary of the Invention" section describes several distinct embodiments of the invention which can be interpreted as the core independent claims.
Independent Claim 1 (Method): This claim outlines a method for plasma collection that personalizes the collection volume for each donor. First, key donor information—weight, height, and hematocrit—is determined. Using this data, the system calculates the donor's total plasma volume and then a specific target collection volume, which is a set percentage of their total plasma. The process involves withdrawing blood, mixing it with an anticoagulant, and separating it into plasma and other components. The system continuously calculates the volume of "pure" plasma (without anticoagulant) that has been collected. The collection process stops precisely when the calculated pure plasma volume matches the predetermined target volume for that specific donor. This method aims to standardize the percentage of plasma collected across different individuals, potentially making the process safer and more efficient.
Independent Claim 2 (System): This claim describes the physical system designed to carry out the personalized plasma collection method. The system includes a venous-access device for drawing and returning blood, a blood separation device (like a centrifuge), and various lines for transporting blood and anticoagulant. A key component is a controller (a computer). This controller is programmed to perform the necessary calculations: determining the donor's plasma volume based on their physical data, setting the target collection volume, and calculating the amount of pure plasma collected in real-time. The controller stops the system's pumps once the target volume is reached, ensuring the collection is tailored to the individual donor's physiology. It may also manage returning other blood components and saline to the donor to maintain their fluid balance.
