BLOOD COLLECTION SYSTEM WITH AUTOMATIC PRESSURE MANAGEMENT AND RELATED METHODS

Abstract:

A blood collection system may include a needle assembly, which may include a needle configured to receive an evacuated blood collection tube. The blood collection system may include a tubing, which may include a distal end and a proximal end. The proximal end may be coupled to the needle assembly. The tubing may include a first flow channel and a second flow channel. The first flow channel may be configured to collapse at a lower pressure differential than the second flow channel.
