Abstract

A self-cannulation support device for home hemodialysis was developed in order to increase the ease of self-treatment by patients. The prototype model made of acrylonitrile-butadiene-styrene (ABS) resin was manufactured using three-dimensional modeling technology. The device was mainly composed of a basement, expansion/contraction, arm, projection, and torsion spring parts. Especially, the arm of the device was energized by the spring to press and fix a venous vessel of the patient's forearm. When cannulation is conducted, the patient's forearm is inserted into the aperture between the basement and the arm of the device. The patient's vessel was pressed by the projecting part and subsequently fixed by a slight movement of the patient's forearm in the direction of cannulation.
