The invention discloses a novel dialysis tube used for hemodialysis equipment. The novel dialysis tube comprises a dialysis control device and a dialysis needle tube used for leading out blood in thebody of a patient. A hemodialysis device is arranged at one end of the dialysis needle tube and connected with a blood reflux unit and a substitution fluid separating and discharging mechanism, wherein the blood reflux unit is used for conveying the blood Z after dialysis and purification back into the body of the patient, and the substitution fluid separating and discharging mechanism is used forseparating and discharging dialysis waste generated after dialysis, the blood is drawn from the body of the patient through the dialysis needle tube, then the function of dialysis is realized under the effect of the blood dialysis device, the blood Z after dialysis and purification is conveyed back into the body of the patient through the blood reflux unit, and meanwhile through the substitutionfluid separating and discharging mechanism, the waste generated by dialysis is discharged. The novel dialysis tube is simple in structure, easy and convenient to operate and capable of efficiently andrapidly dialyzing the blood of the patient, in this way, pains of the patient during blood dialysis are reduced, and the safe reliability of the whole process of dialysis is guaranteed.
