Abstract
Purpose : Reuse of medical devices is decreasing as the medical environment changes. so compare the contrast media injector connecting tubes of medical devices used in the procedure and to find out the appropriate connecting tube type.

Materials and methods : Metal, plastic luer connector in the domestic market were compared with the microangiography similar environment. The performance criteria of the connecting tube were divided into connection ability, pressure ability, non-moving ability and psi change during fixation. In order to minimize the error according to the measurement error, the mean value was measured five times, and the three radiologists were evaluated and analyzed in the same manner.

Results : The connecting ability of plastic connecting tube was excellent, pressure ability was no difference in between products, non-moving ability showed good performance of metal connecting tube. however, it was confirmed that psi (pounds-per-square-inch) increased by 10 ~ 50 psi change during fixation when microcatheter luer connector was fixed.

Conclusions : Results of comparison test of connecting tube type, excluding the fixing ability the plastic connecting tube was better than or equal to that of the metal connecting tube in the evaluation area. Considering the cost side, it is most suitable to use plastic connecting tube after fixing the connector luer.
