| 摘要 |
The invention relates to a method for sterilising/disinfecting water circuits of dental units (1) comprising dental handpieces (2) and a water circuit (3) for supplying liquid from a main supply (4) through corresponding circuit legs or branches (3a, 3b, 3c, 3s). The method comprises at least the following steps: introducing a disinfectant / sterilising liquid in the water circuit (3) for a predetermined length of time; draining the disinfectant / sterilising liquid out of the circuit (3) through the circuit legs or branches (3a, 3b, 3c, 3s); and introducing the user liquid in the water circuit (3); the method further comprising, between the steps of introducing and draining out the disinfectant / sterilising liquid and the user liquid, a step of introducing a fluid from an independent branch (5) in the water circuit (3) for a predetermined length of time, depending on defined parameters, in order to expel from the water circuit (3) all the remaining liquid in the water circuit (3). <IMAGE>
