Abstract
A medical grade tubing that includes a layer of ultra low density polyethylene that has been let down, or drawn down, in diameter approximately 10% to about 50% in an extrusion process and an inner layer of an RF responsive material, the tubing allowing for the selective connection of the tubing to another tubing using a sterile welding device.
Claims17
A medical grade tubing comprising:
- a layer of a non RF responsive material comprising ultra low density polyethylene that has been let down, or drawn down, in diameter approximately 10% to about 50% in an extrusion process;
- and
- an inner layer of an RF responsive material.
Two medical grade tubes that are coupled together using a sterile connection process comprising:
- a first tubing having a non RF responsive layer of ultra low density polyethylene that has been let down, or drawn down, in diameter approximately 10% to about 50% in an extrusion process, and an inner layer of an RF responsive material;
- and
- a second tubing that does not include polyvinyl chloride.
A method for the selective sterile connection of medical grade tubing comprising:
- providing a first medical grade tubing comprising a non RF responsive core layer of ultra low density polyethylene that has been let down, or drawn down, in diameter 10% to about 50% in an extrusion process and an inner layer of an RF responsive material, the first tubing being so constructed and arranged that it can not be sterile connected to a polyvinyl chloride tubing using a welding device;
- and
- connecting the medical grade tubing to another medical grade tubing using a welding device.
