ABSTRACT:
A method of disinfecting a blood tubing set on a dialysis machine after the blood tubing set has been used in a dialysis treatment. One end of the blood tubing set is connected to a disinfection port on the dialysis machine and an opposite end of the blood tubing set is connected to a waste drain. The dialysis machine provides a supply of a disinfectant solution to the disinfection port. A blood pump on the dialysis machine pumps the disinfectant solution from the disinfection port to the waste drain through the blood tubing set to expel contaminants from the blood tubing set. The blood tubing set is preferably connected to a dialyzer which is disinfected when the disinfectant solution is pumped through the blood tubing set. A supply of cleaning solution or water may be pumped through the blood tubing set and dialyzer to expel the disinfectant solution. A supply of air may be pumped through the blood tubing set and dialyzer to expel substantially all fluid from the blood tubing set and dialyzer. A dialysis machine includes hydraulic components for mixing and heating the disinfectant and cleaning solutions and for supplying the disinfectant solution, the cleaning solution, water and air to the disinfection port.
