一种可控进液量的双联腹膜透析装置的设计与应用

Design and application of duplex peritoneal dialyzer with controllable dialysate volume

目的 :设计一种可控进液量的双联腹膜透析装置,方便临床医护人员的操作,为腹膜透析患者提供方便。方法:从患者使用时的安全性和便利性出发进行设计,该装置由进液袋、引流袋、换液口、取液口、排液口、分液瓶、流量调节阀、均力杆组成。进液袋和引流袋均设置有刻度,方便掌握和控制流量;进液袋与引流袋的袋口分别通过连接管连接至换液口,一个换液口即可实现进液输入和透出液引流的功能。结果:该装置可根据患者对透析液的实际需求量进行透析,保证分液瓶中的药量满足患者的需求。同时可减少连接次数,避免频繁更换透析液造成的感染问题,减少腹膜炎等相关并发症的发生。结论:该装置操作简单方便,且可以一次性使用,具有简便、安全性的优点,值得进一步推广使用。

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.
