<P>PROBLEM TO BE SOLVED: To provide an apparatus for closing an injection apparatus in order to prevent an accidental free flow state from occurring. <P>SOLUTION: For this apparatus for preventing the free flow which passes through the injection apparatus, an occluder (104) which is installed in the injection apparatus in order to selectively prevent flows passing through the injection apparatus is used. The occluder can respond to differential pressure in the injection apparatus, or can respond to the compression of the injection apparatus. When a pair of occluders (504 and 508) are continuously used in order, a serial type pump can be formed. <P>COPYRIGHT: (C)2009,JPO&INPIT |
