Vascular access with an indwelling subclavian cannula is now being widely used as an alternative to silastic-teflon shunts or femoral cannulation in patients with end-stage renal failure who are temporarily lacking an arteriovenous fistula. Advantages are the preservation of blood vessels and the avoidance of repeated vein puncture for each dialysis. The only disadvantage of the standard single-lumen subclavian cannula is the need to use a single needle machine. This is an encumbrance especially in the management of acute renal failure. We have developed a double-lumen subclavian cannula which, having 2 blood pathways, does not require the use of a single needle machine. This device function well for temporary vascular access in patients with terminal renal failure who are awaiting AV fistula construction or repair. It is also especially convenient in the management of acute renal failure when there are difficulties in the construction of a shunt.
对于终末期肾衰竭且暂时缺乏动静脉内瘘的患者，留置锁骨下静脉插管作为血管通路正被广泛应用，以替代硅橡胶 - 聚四氟乙烯分流术或股静脉插管。其优点是保留血管且避免每次透析时反复静脉穿刺。标准单腔锁骨下静脉插管的唯一缺点是需要使用单针透析机。这在急性肾衰竭的处理中尤其不便。我们研发了一种双腔锁骨下静脉插管，它有两条血液通路，无需使用单针透析机。该装置对于等待动静脉内瘘构建或修复的终末期肾衰竭患者的临时血管通路效果良好。在急性肾衰竭且分流构建困难时的处理中也特别方便。
