一种新型血液净化装置的体外循环血路系统
摘要：
本发明公开一种新型血液净化装置的体外循环血路系统，包括：主管路、与所述主管路分别连通的泵前侧枝、排气侧枝和肝素侧枝以及针管；所述泵前侧枝管路上设有与其连通的止流管，所述止流管与所述泵前侧枝管路连通处的所述止流管一端内侧设有预穿孔胶塞，另一端开口，所述针管能够通过所述开口插入所述预穿孔胶塞并贯通后与所述泵前侧枝管路连通。使的在减少主管路血液向侧枝管流动，同时保证副导管的功能前提下，减少患者在透析过程中的血液损失。
摘要（英）：

The invention discloses a novel blood purifying device extracorporeal circulation blood loop system comprising a main tube, and a pump front side branch, an exhaust side branch, a heparin side branch and a needle tubing respectively connected with the main tube; the pump front side branch tube is connected with a stop flow tube; the inner side on one end of the stop flow tube in the connecting portion between the stop flow tube and the pump front side branch tube is provided with a prepunch rubber plug, and the other end is provided with an opening; the needle tubing can insert the prepunch rubber plug through the opening, and penetrates and is connected with the pump front side branch tube. The novel blood purifying device extracorporeal circulation blood loop system can prevent main tube blood from flowing into branch tubes, and can reduce patient blood loss in a dialysis process while ensuring the function of an auxiliary catheter.
