The present invention is directed to an assembled syringe for administering powder medicament in the field of medicine. According to the present invention, by using a connecting tube ( 14 ), a solvent bottle ( 8 ) containing diluent communicates with a solute bottle ( 10 ) containing powder by external force, and the diluent is injected into the solute bottle ( 10 ) through the connecting tube ( 14 ) under pressure, after the powder is dissolved and mixed uniformly, the mixed solution is injected directly into a patient or added to a transfusion bottle or a transfusion tube. Both the solvent bottle ( 8 ) and the solute bottle ( 10 ) are packaged into a sleeve ( 5 ) to avoid contamination or cross-infection. Buckles ( 3 ) on the plunger sleeve ( 2 ) are fitted into restricting slots ( 4 ) on the sleeve ( 5 ). The fitting of the slots ( 4 ) and buckles ( 3 ) restricts the position of the syringe, self-locking and controlling the magnitude of force by which the solute bottle ( 10 ) is communicated with the solvent bottle ( 8 ), and controlling the depth of insertion of the needle into the body, and preventing misoperation or damage during transport, fetching and using. The present invention is a novel design with industrial applicability and can be adapted to generalized use in the industries.
