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.
A method of disinfecting a disposable blood tubing set contaminated with blood following a dialysis treatment performed with a dialyzer and said blood tubing set removably attached to a dialysis machine, the dialysis machine having a blood pump and a dialysate line for delivering dialysate to the dialyzer during the dialysis treatment, said method comprising the steps of:
A method of disinfecting a disposable blood tubing set contaminated with blood following a dialysis treatment performed with a dialyzer and said blood tubing set removably attached to a dialysis machine, the dialysis machine having an arterial clamp, a venous clamp, a blood pump and a dialysate line for delivering dialysate to the dialyzer during the dialysis treatment, said method comprising the steps of:
A method of removing contaminated blood from a disposable blood tubing set following a dialysis treatment performed with a dialyzer and said blood tubing set removably attached to a dialysis machine, the dialysis machine having a blood pump and a dialysate line for delivering dialysate to the dialyzer during the dialysis treatment, said method comprising the steps of:
A method of disinfecting a disposable blood tubing set contaminated with blood following a dialysis treatment performed with a dialyzer and said blood tubing set removably attached to a dialysis machine, the dialysis machine having a pump, a waste drain and a dialysate line for delivering dialysate to the dialyzer, said method comprising the steps of:
A method of disinfecting a used, medically-contaminated, single-use blood tubing set following a dialysis treatment performed with a dialyzer and said blood tubing set removably attached to a dialysis machine to transform the used blood tubing set into a non-bio-hazardous state for disposal as non-bio-hazardous waste, said method comprising the steps of:
