Abstract

A multipurpose blood processing bag is described for a system in which anticoagulant and whole blood are mixed outside of the prior art anticoagulated whole blood bag in order to minimize collection lesion. In this system, whole blood and anticoagulant from a multipurpose container are mixed at the phlebotomy needle and the anticoagulated whole blood passed to the anticoagulated whole blood bag. The anticoagulated whole blood may then be separated in a pheresis procedure into components such as plasma or platelets and the separated components stored in the (now empty) multipurpose container.

Claims

1. A blood donation apparatus comprising:

(a) a first flexible bag means for receiving a first fluid which is a mixture of a second and third fluid, said first flexible bag means having an input port and an output port;

(b) a second flexible bag means for containing said third fluid, said second flexible bag means having an input port and an output port;

(c) a source of second fluid;

(d) a three-port-junction connecting means;

(e) a first conduit means for coupling the input port of said first flexible bag means to a first port of said three-port-junction connecting means, a second port of said three-port-junction connecting means being connected to the source of said second fluid;

(f) a second conduit means for coupling an output of said second flexible bag means to a third port of said three-port-junction connecting means, and;

(g) a third conduit means for coupling an input port of said second flexible bag means to an output port of said first flexible bag means;

whereby said third fluid and second fluid may be mixed at said three-port-junction connecting means to form said first fluid and whereby said first fluid may be separated into one or more constituent components in said first flexible bag means and a separated component coupled to said second flexible bags means after said third fluid has been removed from said second flexible bag means.

2. The apparatus of claim 1 in which the first fluid is anticoagulated whole blood, the second fluid is whole blood from a donor, and the third fluid is anticoagulant.

3. A blood donor collection apparatus comprising in combination:

(a) a phlebotomy needle;

(b) a first conduit means;

(c) a second conduit means;

(d) a three-port-junction connector means;

(e) a first flexible bag means having an input port and an output port for containing anticoagulated whole blood said input port being connected to one end of the first conduit means;

(f) a second flexible bag means, having an input port and an output port, for initially containing anticoagulant, said output port being connected to one end of the second conduit means;

(g) the remaining ends of said first and second conduit means being fluidly coupled to respective individual ports of the three-port-junction connector means, the remaining port of which is connected to the phlebotomy needle;

(h) a third conduit means fluidly connecting the outport port of said first flexible bag means to the input port of said second flexible bag means said third conduit means comprising a third flexible bag means having an input port and an output port and tubing means fluidly coupling the output port of the third flexible bag means to the input port of the second flexible bag means and the output port of the first flexible bag means to the input port of the third flexible bag means.

4. An evacuated chamber containing a blood donor collection apparatus comprising in combination:

(a) a phlebotomy needle;

(b) a first conduit means;

(c) a second conduit means;

(d) a three-port-junction connector means;

(e) a first flexible bag means, having an input port means and an output port means for containing anticoagulated whole blood said input port means being connected to one end of the first conduit means;

(f) a second flexible bag means, having an input port means and an output port means, for initially containing anticoagulant, said output port means being connected to one end of the second conduit means;

(g) the remaining ends of said first and second conduits means extending from said chamber and being coupled to respective individual port means of the three-port-junction connector means, the remaining port means being fluidly coupled to the phlebotomy needle;

(h) a third conduit means for connecting the output port means of said first flexible bag means to an input port means of said second flexible bag means.
