Abstract
A medicinal solution injection apparatusincludes a composite needleincluding a needle base portion, an injection needle, and an adjustment needle, a pressure generating portionconfigured to discharge a compressed air, a measuring portionconfigured to measure a filling amount and a filling speed of a medicinal solution by measuring a position of a gasketof a syringe, and a control portionconfigured to control the pressure generating portionand the measuring portion. The compressed air is introduced into a vial containerthrough an edgeof the adjustment needlelocated above a liquid surfaceof the medicinal solution in the vial container(outside the liquid surface) to press the liquid surfaceof the medicinal solution downward, so that a medicinal solutionis injected into the syringethrough an edgeof the injection needlein the medicinal solution. The medicinal solution injection apparatuscan accurately and efficiently inject the medicinal solutionof the vial containerinto the syringewhile suppressing the medicinal solutionfrom foaming.
