Whole blood collection and processing method
First Claim
1. A method for making a blood collecting system comprising:
- providing a phlebotomy needle, first and second tubes, a leukocyte removal filter having an inlet and an outlet, a single blood-collection bag that is not connected to satellite bags for receiving separated blood products, and anticoagulant;
connecting said needle to an end of said first tube;
connecting another end of said first tube to the inlet of said filter;
connecting the outlet of said filter to an end of the second tube;
connecting another end of the second tube to said blood-collection bag; and
placing said anticoagulant in said blood-collection bag before connecting said blood-collection bag to said second tube;
wherein said method does not comprise connecting another bag to the fore-mentioned components.

Abstract
A method is disclosed for collecting and processing whole blood. Whole blood is collected at several remote donor sites and transported to a central blood-processing center, where information regarding demand for blood products is used to direct processing of whole blood into blood products. Whole blood is initially collected in collection bags unattached to satellite bags instead of commonly used multiple bag sets. When the determination is made at the blood processing center as to which blood products are to be made, the appropriate satellite bags and/or other system components are sterile docked to the blood-collection bag and the whole blood is processed. The use of blood-collection bags initially unattached to satellite bags eliminates waste and simplifies the transportation and processing of whole blood. Also disclosed are blood collection systems that remove leukocytes and collect whole blood into blood-collection bags unattached to satellite bags.

13. A blood collection system comprising:
-
a phlebotomy needle;
a first tube in fluid communication with said needle;
a whole blood leukocyte removal filter having an inlet in fluid communication with first tube;
a second tube in fluid communication with an outlet of said filter;
