Abstract

BACKGROUND

There are special requirements for draining a pouch, e.g. length, flexibility and ability to drain highly viscous urine.

METHODS

We checked in vitro the flow time of pure and synthetic urine thickened with hydroxyethylcellulose (0.125% and 0.250%, HEC) on selected catheters.

RESULTS

We found for SpeediCath Compact Male (SCCM) as a CH12 catheter the shortest flow times for undiluted and urine thickened with 0.125% and for SafetyCath Plus for urine thickened with 0.250%. For catheters with CH14 we found significantly shorter flow times for all tested solutions. The flow time does not depend on amount and area of the catheter eyes; we found no difference in the flow time for 4-eye (MobiStom) and 2-eye catheters.

摘要

背景

引流袋有特殊要求，例如长度、柔韧性以及引流高粘性尿液的能力。

方法

我们在体外检测了纯尿液以及用羟乙基纤维素（0.125%和0.250%，HEC）增稠的合成尿液在选定导管上的流动时间。

结果

我们发现，作为CH12导管的SpeediCath Compact Male（SCCM）对于未稀释尿液以及用0.125%增稠的尿液流动时间最短，而SafetyCath Plus对于用0.250%增稠的尿液流动时间最短。对于CH14导管，我们发现所有测试溶液的流动时间显著更短。流动时间不取决于导管眼的数量和面积；我们发现4眼（MobiStom）和2眼导管的流动时间没有差异。
