Platelet freezing bag

摘要

A platelet freezing bag made of pliable plastic material has two needle ports designed to accept a syringe needle for transferring platelet concentrate and diluent plasma into the bag and a large draining port. The ports are protected and closed by pull-apart seals. The draining port is separated from the platelet receiving compartment by a push-apart seal which can be opened by exerting gentle pressure on the contents of the bag.
