Instillator for injection of ringer's solution

Instillator for injection of a Ringer's solution, comprising:

• a cylindrical instillation container which is made out of a transparent material;
• a solution inflow tube which is formed on the top of the instillation container in a projecting manner, has a penetration needle, which penetrates a rubber stopper for closing a solution bottle, formed on the top of the solution inflow tube, and has a solution guide passage, which guides a solution stored in the solution bottle to flow into the instillation container, formed along a vertical centerline of the solution inflow tube;
• and
• a lower stopper which is inserted into the bottom of the instillation container, has a solution drainage passage, which is used to discharge the solution filling the instillation container, formed on the top surface of the lower stopper in a penetrating manner so that the solution drainage passage reaches the bottom surface of the lower stopper, and has a tube connector formed on the bottom of the solution drainage passage in a projecting manner,
• wherein a drainage guide plate with a drainage hole is fixedly inserted into the bottom of the instillation container to downwardly discharge the solution guided into the lower portion of the instillation container,
• a precise flow regulator is coupled onto the outer circumference of the drainage guide plate to be rotated from side to side, and
• an instillation hole communicating with the tube connector is formed on the inner surface of the bottom of the precise flow regulator.
