Patent number: 7571744Abstract: An improved tubing device, preferably for use in the medical industry is provided. The tubing device provides a seamless transport path by using the tubing itself as the transport means without any other internally wetted parts, or connections, to provide a substantial reduction in the number of fluid contact components, and eliminate the need for cutting tubes into segments to be later bonded via tubing connectors. This can reduce the risk of contamination of the transported materials and can also reduce the use of chemicals such as adhesives and bonding agents.Type: GrantFiled: January 31, 2002Date of Patent: August 11, 2009Assignee: Hemerus Medical, LLCInventors: Majid Zia, Anthony J.
