Abstract: The present invention is directed to an assembled syringe for administering powder medicament in the field of medicine. By using a connecting tube, a solvent bottle containing diluent communicates with a solute bottle containing powder by external force, and the diluent is injected into the solute bottle through the connecting tube 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 tube. Both the solvent and solute bottles are packaged into a sleeve to avoid contamination. Buckles on the plunger sleeve are fitted into restricting slots on the sleeve. The fitting of the slots and buckles restricts the position of the syringe, self-locking and controlling the magnitude of force by which the solute bottle is communicated with the solvent bottle, controlling the depth of insertion of the needle into the body, and preventing misoperation or damage during transport, fetching and using.

Abstract: 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).
