SECONDARY FILTER CLEANING METHOD IN BLOOD PLASMA FILTRATION METHOD |
摘要 |
In a blood plasma filtration method including a primary filtering for separating blood into corpuscule and plasma, and a secondary filtering for cleaning the separated plasma by removing harmful macromolecular substances therefrom, the cleaning of the secondary filter is done by introducing a cleaning liquid the quantity of which corresponds to 5-50 % of the priming volume of the filter into an inner chamber or an outer chamber or both thereof in the filter every time a filtration pressure reaches 70-100 % of the resistible pressure of the filter. This enables the time required to carry out the filtration of blood plasma to be reduced to about 60 - 70 % of that in a conventional method of this kind, the patient binding hour to be reduced, and the quantity of a cleaning liquid or blood plasma discharged wastefully to the outside of the system to be reduced. |
