US 2004/0073192 A1 · Intravenous fluid delivery set

Abstract

A flexible tubing for an intravenous fluid delivery set including an elongate tubing member formed of aliphatic polyether polyurethane. The set may include connectors to a container and an intravenous needle, and additional connectors for components placed in line with the tubing, with hollow posts on the connectors, with the tubing ends adapted to friction fit over the posts. The posts may have outer diameters which are tapered from a first diameter to a second diameter, where the inner diameter of the tubing ends are less than the second diameter. A method of delivering therapeutic fluid is also shown including providing the delivery set, providing a flow path by forcing tubing ends over connector posts in an in-line arrangement, and then controlling the flow of the therapeutic fluid between the container and the intravenous needle through the fluid flow path.

A flexible tubing for an intravenous fluid delivery set, comprising an elongate tubing member formed of aliphatic polyether polyurethane.

A method of delivering therapeutic fluid, comprising:

providing an intravenous fluid delivery set including:
a first connector,
a second connector,
at least one set component chosen from the group of filters, valves, flow control devices, needle-less connectors and pumps, said component including third and fourth connectors, and
first and second aliphatic polyether polyurethane elongated hollow tubings, each of said tubings having open distal and proximate ends;
providing a PVC-free fluid flow path between a therapeutic fluid container and a patient by
connecting said first connector to a container,
connecting said second connector to an intravenous needle,
connecting the proximate end of the first tubing to the first connector and connecting the distal end to the third connector of one of said at least one set component, and
connecting the distal end of the second tubing to the second connector and connecting the proximate end to the fourth connector of said one of said at least one set component;
and
controlling the flow of said therapeutic fluid between said container and said intravenous needle through said fluid flow path.
