초록 ▼

A hemodialysis apparatus includes a sterile filter whose outlet, which is usually closed, is connected to a line leading to a discharge outlet in wherein a bypass valve is employed which can be opened at predetermined intervals both during treatment and during flushing operations. The sterile filter has a primary chamber and a secondary chamber. When the bypass valve is opened during treatment, dialysis solution flows out of the primary chamber of the sterile filter and flushes the pyrogens and particles disposed on the membranes of the filter into the discharge. No sterilizating filtration of the dialysis solution takes place through the pores of the membrane because the flow resistance present in the adjoining dialyzer, in conjunction with a degree of clogging of the pores, prevents such a flow. A ventilation means may be provided whereby the bypass circuit of the sterile filter can be ventilated. The bypass circuit may also be employed for a pressure retaining test.

대표청구항 ▼

A method for cleaning a sterile filter (38) of a hemodialysis apparatus, said hemodialysis apparatus comprising a dialyzer divided by a membrane into two chambers, the first chamber being connected into a dialysis solution path and a second chamber into a blood path, the dialysis solution path comprising: a supply line which extends from a means for preparing dialysis solution to the dialyzer and into which a first shutoff member is connected and an exit line which extends from the dialyzer to the discharge and onto which a second shutoff member is connected, a pump for conveying the dialysis solution in the dialysis solution path, an ultrafiltration means provided between the shutoff members in the dialysis solution path, a bypass line which connects the supply line to the exit line of the dialysis solution path and into which a bypass valve is connected, and a sterile filter (38) which is divided by a germ-retaining membrane into a first filter chamber (42) and a second filter chamber (44), with a first portion of the supply line of the dialysis solution to the first filter chamber of the sterile filter and a second portion of the supply line of the dialysis solution from the second filter chamber of the sterile filter to the dialyzer, wherein an outlet (48) of the first filter chamber (42) of the sterile filter (38) is connected to a bypass line (54) leading to an exit line (24), said method comprising the steps of: opening the bypass valve (58) at predetermined intervals of time during dialysis by means of a control unit (82) in order to bypass said sterile filter; and closing the bypass valve (58) at predetermined intervals of time during dialysis by means of the control unit 82.
