A hemodialysis machine includes a purified water tube connected with at least
one
or tow water pumps in parallel. Each of the water pumps is connected with a reagent
jug for taking reagent or disinfectant into water tubes so as to run dialysis process
or sterilize tubes. The present invention features on that an ozone water device
is coupled with a water inlet end of the purified water tube so that the ozone
water is used to clean the tubes of the hemodialysis machine for avoiding the problem
of disinfectant residuals.
