摘      要：A cylindrical region in straight type indwelling needles currently used for hemodialysis at clinical sites induces noncontinuous widening of the blood-flow channel in the region of the needle-hub connection.High-flow type indwelling needles with a funnel-shaped region have therefore been marketed in recent *** few reports provide any experimental answers to issues such as the increase in blood removal flow rate provided by funnel-shaped as opposed to straight type and the difference in their suction *** the present study, we investigated the difference between the actual flow rate and suction pressure of each type of indwelling needle at different set flow *** these results, we confirmed that a high-flow type maintains a higher flow *** a high-flow type maintains a higher actual flow rate than a straight type with the same suction pressure. © 2021, Japan Soc. of Med.
