Abstract
It is usefullness double lumen catheter (DLC) for temporary blood access as hemopurification. However, it seems a little effect on hemodialysis. We modelled on experimental systems of vessel tubing. Modelling vessel system consists of silicone tube, running water (Qw) in vessel tube from 200ml/M. till 400ml/M. Outflow rate (QB) in arterial side of DLC from I00ml/M. to 250ml/M. ran. DLC recirculation rate is measured by PSP solution. On change of Qw 400ml/M flow rate is the best, on change of QB I00ml/M flow rate is the most effective. Therefore, DLC recirculation rate is not only QB but also Qw most influenced. For the reasons mentioned above, as for Qw of much volume DLC is effective.
