PURPOSE: To prevent remains of a medicine in a medicine vessel by arranging a small hole to communicate the inside and the outside in a lower position of a cannula in the medicine vessel, dividing the inside of a socket into an upper chamber to pass a medical liquid and a lower chamber to pass a medical liquid in which a medicine is dissolved or mixed by a dividing plate, and arranging a communicating hole of the upper and lower chambers in the dividing plate. CONSTITUTION: A cartridge is installed in a socket, and a cannula 27 is inserted into a communicating hole 15 of a partition plate 14. Then, an upper port 28 is positioned in a medicine vessel, and a lower port 29 is positioned in a lower chamber 18. Therefore, a medical liquid of a medical liquid vessel enters an upper chamber 17 from a socket inlet 11, and enters the medicine vessel from a cavity 34 outside of the cannula 27, and contacts with a medicine, and rises while mixing with it. Lastly, it flows into the lower chamber 18 from the upper port 28, and drips out of a liquid dripping port 7. The medical liquid vessel becomes empty, and when an inflow to the medicine vessel stops, the medical liquid in the medicine vessel flows to the lower chamber 18 through a small hole 35 or a small hole 36. |
