Miniature Couplings Incorporate RFID Technology

Corinne Litchfield


RFID technology is integrated into a miniature coupling to ensure safe connections.

A maker of quick-disconnect couplings has introduced subminiature couplings with radio-frequency identification (RFID) capability. The IdentiQuik SMC couplings from Colder Products Co. (St. Paul, MN; allow users to electronically confirm connection accuracy.

Luer-type safety connectors are used to prevent medical devices from being connected to an IV line. The IdentiQuik couplings are an alternative to such connectors. The RFID-equipped couplings add another level of safety to the company’s line of standard connectors and can also record data for increased patient safety.

RFID capability is integrated into coupling bodies or inserts. Before the final connection is made, the coupling halves automatically exchange product data. This enables the connected equipment to electronically identify the mated device or media line and its characteristics. The couplings can be used with small critical air or fluid lines. Applications include blood pressure cuffs, surgical equipment, blood analyzers, tube sets, and analytical instrumentation.

“The couplings enable users to avoid liability issues that can arise from critical misconnections,” says Jim Brown, medical business unit manager. “The incorporation of RFID further ensures that equipment is set up correctly and all lines are accurately connected.”

Made from acetal and polypropylene, the units are available in 1/16-in., 1/8-in., and 3-mm hose barb sizes. The couplings with RFID capability are offered as
in-line bodies and inserts, with valved or nonvalved options; they also feature a secure, twist-to-connect design.

Operating pressures range from vacuum to 100 psi. Operating temperatures range from –40° to 180°F for acetal and 32° to 180°F for polypropylene.
