<P>PROBLEM TO BE SOLVED: To provide a disposable syringe which is never used again by easily breaking down its structural integrity. <P>SOLUTION: After the syringe is used by combination with a needle means, a plunger is successively pushed and a carrier is moved to the small diameter part of a barrel along an axial direction relative to a side wall. In this case, a yielding segment is pushed in a diameter direction by movement along a pushing region and deformed. Engagement with the retaining segment of a retained region is released, so that the structural integrity is broken down and the syringe is never used again. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
