Disposable plastic blood bags refer to the biomedical devices that are used for collection, storage, transportation, and transfusion of blood and its various components, such as red blood cells, white blood cells, and platelets.
These blood bags are commonly made from plastic materials and polyvinyl chloride (PVC), and their manufacturing process includes compounding, extrusion, molding, welding, solution, sterilization, and inspection for contamination.
A blood bag package consists of collection tube, needle, needle cover, and a clamp. The disposable plastic blood bags have replaced the usage of glass bottle for collection and storage of blood and blood components. This is due to various features offered with disposable plastic bags, such as it enables the separation of blood components in a more sterile manner and eliminate the requirement of cleaning processes. It also reduces the chances of breakage during transportation.
