    • A blood chamber for extracorporeal blood circuits comprises a container body (2) made in a single piece by blowing of a plastic material, and has a plurality of connection ports (3, 4) for fluid communication with outside; each connection port (3, 4) comprises a tubular mouth (6) having a truncoconical internal surface (61) which is coupled in a fluid-proof coupling to a tubular first part (101) of an insert (10), made by injection molding of a plastic material. The insert (10) has a truncoconical and smooth internal surface (102) which is coupled by gluing with a solvent to an end zone of a fluid transport tube (7, 8). The coupling between the blood chamber and the fluid transport tubes is very strong and reliable. The blood chamber is part of an extracorporeal blood circuit which is operatively associated to a dialysis machine.
    • 用于体外血液循环的血液腔室包括通过吹塑料材料制成单件的容器主体(2),并且具有用于与外部流体连通的多个连接口(3,4) 每个连接端口(3,4)包括具有截头内表面(61)的管状口(6),该表面在流体防止联接器中与插入件(10)的管状第一部分(101)联接,通过注射 模塑塑胶材料。 插入件(10)具有截面和平滑的内表面(102),其通过用溶剂粘合到流体输送管(7,8)的端部区域而联接。 血液室和流体输送管之间的耦合是非常强大和可靠的。 血液室是与透析机可操作地相关联的体外血液回路的一部分。
