<P>PROBLEM TO BE SOLVED: To provide: a mixed injection instrument coupled body preventing easy breakage of a branch pipe by an application of an external force and retaining the rigidity of the whole mixed injection device when executing mixed injection work; and a simple coupling auxiliary device for use in the coupling of the mixed injection instruments, in the mixed injection instrument having a form connected with a plurality of mixed injection instruments. <P>SOLUTION: This coupling auxiliary device 5 is used for the mixed injection instrument coupled body that is formed by coupling a plurality of mixed injection devices 2, wherein adjoining mixed injection instruments are connected by a connecting tube 4 having flexibility and the inside of the mixed injection instruments are communicated with each other, and is characterized in being attachable between the mixed injection instruments and having a vulnerable site 6 whose fracture strength is lower than that of other sites, at its one portion. <P>COPYRIGHT: (C)2009,JPO&INPIT |
