Abstract：In order to explore a more scientific, safe and efficient blood return method of hemodialysis,
and avoid the disadvantages of blood return methods in current clinical practice, this study designed a Y
type internal arteriovenous fistula puncture needle. Before hemodialysis treatment, the puncture needle
is used in patients with fistula of the artery end, and the vein end uses the conventional straight needle;
by the end of hemodialysis, side hose of Y type needle is used to return the blood to the patient by
physiological saline whole course, which is a one-way and closed blood return method. This method has
the advantage of the traditional blood return methods, and at the same time avoids the shortcomings and
limitations. Using the Y type puncture needle to return blood by one-way and closed method can reduce
the occurrence of various nursing risks in the blood return operation, protect the internal arteriovenous
fistula, improve work efficiency, and enhance the safety of hemodialysis patients.
