<P>PROBLEM TO BE SOLVED: To provide a blood reservoir equipped with a blood-collecting part which has a comparatively simplified circuit configuration, is suitable for a non-sharpened needle, improves operability and has a connection mechanism capable of securing safety and sanitariness. <P>SOLUTION: The blood reservoir is provided with a blood-collecting part 5 on the side of a blood-collecting needle in the middle of a blood transfusion tube 2 and a communication member 4 is provided on the side of a reservoir body 1 to provide the comparatively simplified circuit configuration. Besides, the blood-collecting part 5 is provided with a partition film having a slit to connect the blood-collecting part 5 and an insertion member such as the non- sharpened needle only by pressing the insertion member into the slit provided on the partition film in the case of blood-collecting operation and there is an effect to improve safety and operability. Further, since the partition film can keep liquid-tightness during a connection or disconnection and a film body is not shaven away in the case of insertion, the blood reservoir capable of keeping sanitariness can be provided. <P>COPYRIGHT: (C)2003,JPO |
