Objective： Explore BeiLang use Diapact CRRT blood purification devices in the original continuity static-static hemofiltration treatment on the basis of the model of, realize the continuity of plasma filtration adsorption treatment of new functions, Methods： through to the BeiLang Diapact C R R T continuity static-static hemofiltration pipeline for simple modification treatment, increase the tee connecting pipe a root, extended the original treatment mode. Results: A good way to realize the CPFA treatment. Conclusions: Use BeiLang DDiapact CRRT blood purification devices original continuity static-static hemofiltration treatment mode as the foundation. Combined with the design characteristics of the machine, and realize the continuity of plasma filtration adsorption treatment, the principle of the new function method and clinical application.
