PROBLEM TO BE SOLVED: To provide the structure and the dissolving method of a syringe with a medicine dissolving mechanism, which enables to carry a patient the syringe and prepare injection a patient to be injected by the patient himself at need, and especially, in the dissolving process of a medicine, a shock, disturbance of flow of a liquid and the other mechanical strength can be prevented from being applied to the solution to the utmost. SOLUTION: A syringe with a medicine dissolving mechanism comprises a cylinder ampoule 2, an outer cylinder 3, a needle pipe holding part 4 and a spindle driving mechanism 5. In the cylinder ampoule 2, a medicine in the front space and a solvent or a dispersion medium in the rear space are respectively enclosed in the separate state, and when using the syringe, an attachment is fitted to a spindle 14 connected to the rear partition wall and pushed-in to move the rear partition wall 10 forward, the intermediate partition 9 is also moved forward with the above movement, so that, when a bypath is opened to let a solvent or a dispersion medium flow in the front space, it is possible to observe the status where a solvent or a dispersion medium flows into the front space from the outside to come into contact with the medicine. In order to manually control the inflow speed, the attachment is exposed to the outside of the ampoule. |
