Abstract: Objective To improve a set of new plasma collector program management and disposable lines to achieve the blood collection, O3 treatment,plasma virus inactivation and return effective integration in order to provide multifunctional fusion blood treatment technology for some diseases. Methods The design abandoned on the NGL XJC-2000 plasma collection procedure, the control scheme of single-chip machine was improved to the overall solution of“control system + interactive system”. A blood collection bag was connected at the front of the line for ozonated -autohemotherapy technology(AOBT) and a set of plasma collection bag was connected for autologous plasma virus inactivation (APVI),so effectivelly integrated two treatment techniques. Results The plasma collector successfully extended the single function of plasma collection to the multifunctional blood therapy integrated machine, which provided more convenience for some patients' blood treatment. Conclusion The fusion of improved plasma collector and the pipelines has achieved good application results, which improved the timeliness of blood therapy treatment. It was worthy of clinical application and promotion.
