Dalkon 盾尾丝与其它类型宫内节育器的单或双纤维线尾丝不同。标准的 Dalkon 盾尾丝在一个薄尼龙鞘内含有400条龙尼纤维。有人认为这种多纤维尾丝起一根灯芯的作用,可能通过毛细管作用使阴道微生物离开尾丝,穿过尼龙鞘的裂隙进入宫腔,裂隙常出现予尾丝近端的双结处,是使用个别节育器经常发生宫内感染的潜在途径。作者通过对Dalkon 盾尾丝的电镜扫描研究,认为病原体可通过毛细管作用,经过多纤维尾丝的全长或微生物经过尾丝双结两端所暴露的纤维到达子宫内。实验材料取自五例使用过的和两个新 Dalkon Dalkon shield wires are different from single or dual-fiber tail wires in other types of IUDs. The standard Dalkon shield contains 400 RONY fibers in a thin nylon sheath. Some people think that this multi-fiber tail filament from the role of a wick, capillary action may be left vaginal microorganisms through the crack in the nylon sheath into the uterine cavity, often appear to the proximal end of the double-tailed wire junction is Potential ways to use intrauterine infection often occur with individual IUDs. By scanning electron microscopy of the Dalkon shield wire, the authors suggest that pathogens can reach the uterus via capillary action, through the full length of the multifilament tail, or through the fibers exposed by the microorganisms at both ends of the double tail wire. Experimental materials were taken from five used and two new Dalkon
