Automatic safety infusion catheter needle
 An automatic safety infusion catheter needle including: a trifurcate connector having a first and a second connecting sections coaxially aligned with each other, the end of the second connecting section being fitted with a rubber cap; an infusion soft needle inserted on the first connecting section of the trifurcate connector; a steel needle having a needle body slidably fitted in a sleeve and axially passed in the soft needle, the sleeve being connected with the second connecting section of the trifurcate connector; and an infusion catheter serially connected with a third connecting section of the trifurcate connector for infusion of liquid medicine through the soft needle into the body of a patient. After injection, the steel needle is withdrawn from the rear side of the sleeve to retract and locate and hide the needle body of the steel needle in the sleeve so as to avoid impalement and infection of the medical personnel and the liquid medicine flowing from the infusion catheter into the trifurcate connector will automatically flow from the first connecting section through the soft needle into the body of the patient. Therefore, the medical personnel can perform the injection procedure leisurely.
