<P>PROBLEM TO BE SOLVED: To provide a check valve suitable for use in a blood flow path and an infusion flow path where a valve operation is stable. <P>SOLUTION: In the check valve, a valve body 4 provided with an elastic thin peripheral edge part 45 is disposed so as to interrupt a flow path; the flow path is opened by the elastic displacement of the thin peripheral edge part 45 of the valve body by a fluid pressure from one side of the flow path, and the thin peripheral edge part 45 is elastically restored and displaced to close the flow path when the fluid pressure disappears. <P>COPYRIGHT: (C)2009,JPO&INPIT |
