A clever concept illustrates the role of sophisticated design approaches in advancing the use of plastics in medical applications. The new design also shows the increasing importance of bovine-free additives in medical plastics.
The innovation comes from Value Plastics (Fort Collins, CO), which developed new single-use ports for transferring fluids and drug compounds in the biopharmaceutical industry.
Parabolic lead-ins on ports reduce the time required to drain a bag by up to 24%, according to Ken Davis, Value Plastics' global marketing manager.
Alignment ribs improve fluid flow dynamics by reducing shear impact as material exits the bag. For widespread industry compatibility, the new ports are designed to work with common tubing sizes, as well as industry-standard fittings, filters and other devices.
The bag ports have an animal derivative-free qualification, USP Class VI certification, heat sealing conformance with polyethylene bags and a 24-hour resistance to alcohol stress cracking....
