The results of these tests demonstrated that aspiration through 30-gauge needles is possible, but since the flow rate is so diminished its clinical application is questionable. The evaluation of the physical properties of these needles proved them to be tough, durable, and suprisingly resistant to breakage, even under the most extreme manipulations and stresses. The insertion of needles into the plastic material clearly showed that the needles are always deflected toward the side without the bevel (the side that contains the point). Finally, the deposition patterns of the injected fluid in tissue have no relationship to the bevel.
这些测试结果表明，使用30号针进行抽吸是可行的，但由于流速大大降低，其临床应用存在疑问。对这些针的物理特性评估表明，它们坚韧、耐用，即使在最极端的操作和压力下也令人惊讶地抗断裂。将针插入塑料材料中清楚地表明，针总是偏向没有斜面（包含针尖的一侧）的那一侧。最后，注入组织中的液体的沉积模式与斜面无关。
