Infusion, dialysis and ECC tubing

Lay-flat tubing for infusion and feeding solutions is for administration of standard infusion solutions, PVC-incompatible, and light-sensitive solutions. Applications include extracorporeal circuits (ECC). The ECC is the path the hemodialysis patient's blood takes outside of the body. Such applications consist of a hemodialysis machine, dialyzer and the plastic tubing. The infusion, dialysis and ECC tubing is made from PVC, EVA and PUR materials.

Double-hinged feed assembly

ULTRA R/S silicone extruder has a double-hinged roller feeder. The first hinge gives access to the feed roll for fast cleaning of the roll surface and feed opening, and it makes it easier to adjust the scraper blade. The second hinge allows simple feed-roll removal for change-out or cleaning of bearings. American Kuhne Inc., 31 Connecticut Ave., Norwich, CT 06360, (860) 886-7745, www.info.hotims.com/18367-251

Multiresin extrusions

Custom tubing extrusions are made from materials such as Pebax copolymer, nylon, polyurethane, polyethylene, polycarbonate, and thermoplastic elastomers such as C-Flex. Capabilities include smaller, multi-lumen configurations and single lumens to 0.500 in. Also available are close-tolerance profiles in single and multilumen geometries, and in small engineering study lot sizes or large production volumes.

Composites for guide-wire applications

Polyimide tubing is for cardiovascular catheters, urological catheters, and low-invasive medical devices with IDs ranging from 0.10mm to 2.11mm, tight tolerances, and various wall thicknesses. Custom ID configurations are also available. Braid and coil reinforced designs are available for additional torque and column strength. PTFE/FEP composites and PTFE liners reduce surface friction.

Extensive multilumen capabilities

Custom parts can range from single-lumen tubing to coextrusions and multilumen tubing, up to 28 lumens or more, depending on the application. Formulations are clear, pigmented, or radiopaque. Wire or thread also can be included as a substrate reinforcement to provide added strength, kink or stretch resistance, and electrical conductivity. These capabilities are used in specialty two- and three-way catheter mainshafts, drainage tubes, catheters, vascular loops, and balloon cuffs.

Thin-wall capability

Braided catheter shaft tubing can be manufactured with walls as thin as .007-in. thick. Braided catheter shaft can be spooled or cut to lengths. After braiding, a second extrusion applied on top of the braided tube encapsulates the braid and provides a smooth finish.

Diameter changes made easy

This puller combines automatic bump and taper forming with cut-to-length features. It is used with an extruder for plastic layered tubes or solids in various diameters. The machine automatically adjusts base diameter, profile changes, and tapers. The extruded plastic tube can be sized by varying pull speed and extrusion die air pressure. After forming the profile, it is measured, while speed and pressure are automatically adjusted as needed. Product is then cut to a selected length.
