A new open-ended guide wire with a large internal diameter was compared with two other open-ended guide-wire and catheter infusion systems. Simple experiments were performed to compare flow rates and ability to track. The larger internal diameter of the new wire allowed higher flow rates and accepted an 0.025-inch (0.64-mm) guide wire. The flexibility of the new infusion wire was shown to be equivalent to that of the catheter system. The authors conclude that the new wire has advantages in terms of flow rates and ability to track, compared with presently available infusion systems.
一种具有大内径的新型开放式导丝与其他两种开放式导丝及导管输注系统进行了比较。进行了简单实验以比较流速和跟踪能力。新导丝较大的内径允许更高的流速，并能容纳0.025英寸（0.64毫米）的导丝。新的输注导丝的柔韧性被证明与导管系统相当。作者得出结论，与目前可用的输注系统相比，新导丝在流速和跟踪能力方面具有优势。
