## Abstract

An instillator for injection of a Ringer's solution temporarily stores Ringer's solutions or others, and couples a precise flow regulator onto an instillation container, thereby allowing the solutions to be administered more accurately, preventing accidents from happening because the regulator is out of a patient's reach, and allowing a connected tube to be easily arranged. The instillator includes an instillation container, a solution inflow tube with a penetration needle and a solution guide passage, and a lower stopper with a solution drainage passage and a tube connector, wherein a drainage guide plate with a drainage hole is inserted into the container to discharge a solution downwardly, a precise flow regulator is coupled onto the plate to be rotated from side to side, and an instillation hole communicating with the tube connector is formed in the regulator.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The instillator for injection of a Ringer's solution according to claim 1, wherein a solution guide plate for guiding the solution falling via the solution inflow tube to flow towards the solution drainage passage is inclinedly formed over the range from an upper position on the inner circumference of one lateral side of the instillation container to a position adjacent to the solution drainage passage formed on the top surface of the lower stopper.

### Claim 3 (depends on 1)

The instillator for injection of a Ringer's solution according to claim 1, wherein the instillation container has a date marking portion on which a replacement date is marked formed on the outer circumference of the upper portion thereof.
