Abstract
A double lumen cannula for single needle hemodialysis is demonstrated. By this cannula, it is possible to make single needle hemodialysis without using the solenoid clamp.
A model experiment was performed to evaluate the effect of this cannula on pressure and blood flow of the dialysis system, and also on the removal of substances. These results are as follows.
1) Sufficient blood flow was obtained through this cannula (maximum, 170ml/mm).
2) Out flow resistance was approximately 1.5 times higher than 16 G-medicut cannula.
3) In the clearance of both creatinine and urea, there was no difference between this method and the two puncture dialysis.
