Design and application of duplex peritoneal dialyzer with controllable dialysate volume / 医疗卫生装备

ABSTRACT

Objective To develop a duplex peritoneal dialyzer with controllable dialysate volume.Methods The dialyzer was designed with considerations on safety and convenience,which was composed of a dialysate feeding bag,a drainage bag,a dialysate changing opening,a dialysate taking opening,a dialysate outlet,a delivery flask,a flow control valve and a compensating bar.There were scales calibrated on the dialysate feeding bag and drainage bag to facilitate flux controlling.The openings of the dialysate feeding bag and drainage bag were connected with the dialysate changing opening by adapting pipe,and the dialysate changing opening could fulfill dialysate input and used dialysate drainage.Results The dialyzer realized dialysis based on actual requirements of the patient,decreased the times for connection to prevent infection due to frequent changing,and lowered the incidence rates of corresponding complications such as peritonitis.Conclusion The disposable dialyzer has easy operation,convenience and high safety,and thus is worthy promoting practically.
