Blood collection monitoring device and method

摘要

This invention is directed to apparatus and a method for monitoring the collection of blood from a donor so as to minimize trauma to the blood so collected. The system closely monitors the rate of collection of blood and regulates the rate of mixing of anticoagulant therewith so as to maintain a substantially constant ratio of anticoagulant to blood throughout the collection process. The system also includes built-in warning devices for indicating when the collection process is not proceeding according to a prescribed pattern.
