Abstract
An insertion guide is used for inserting an arterial needle, which takes blood out from the body, and a venous needle, which returns purified blood into the body, into one or two fistulae formed in a vein running beneath the skin of the arm. The insertion guide may include a holder having an arterial guide hole, which guides the arterial needle downwards at an incline from the shoulder side to the wrist side relative to the fistula, and a venous guide hole, which guides the venous needle downwards at an incline from the wrist side to the shoulder side relative to the fistula.
