## Abstract

A three-component mixing apparatus and a three-component mixing adhesive kit, which allow anyone to easily and uniformly mix three kinds of drugs in mixing a three-component adhesive used in, e.g., surgical procedure (or treatment) or dental procedure (or treatment), includes a syringe filled with a first drug; a plunger; and an infusion-needle connector having a connecting part for a second drug container and a connecting part for a third drug container and a confluent path formed on a base end part. The first drug, the second drug and the third drug are mixed in the syringe by removably attaching the infusion-needle connector to a discharge opening of the syringe, the second drug container to its connecting part and the third drug container to its connecting part and then pulling the plunger inserted into the syringe to introduce the second drug and the third drug into the syringe.

## Claims

### Claim 1

A three-component mixing apparatus comprising:
a first drug, a second drug and a third drug;
a syringe in which a discharge opening is formed on a leading end part and which contains said first drug;
a plunger configured to be inserted into the syringe and in which a seal member is mounted;
a second drug container composed of a container body containing said second drug and a cap body attached to an opening of the container body and having a circumferential flange in a lower end thereof;
a third drug container composed of a container body containing said third drug and a cap body attached to an opening of the container body and of the third drug container having a circumferential flange in a lower end thereof; and
an infusion-needle connector having a lead end part and a base end part, the lead end part including a connecting part for the second drug container filled with said second drug and a connecting part for the third drug container filled with said third drug, the base end part including a confluent path,
wherein the apparatus is configured to mix said first drug, said second drug and said third drug in the syringe by attaching the second drug container to the connecting part for the second drug container, attaching the third drug container to the connecting part for the third drug container, and attaching the discharge opening of the syringe in a removable manner to the confluent path of the base end part of the infusion-needle connector; and then pulling the plunger against the syringe to introduce said second drug of the second drug container and said third drug of the third drug container into the syringe via the infusion-needle connector, and
wherein a plurality of protrusions over which the circumferential flange of the second drug container and the circumferential flange of the third drug container are moved are formed on an inner periphery of the connecting parts separately at a predetermined interval to allow the second drug container and the third drug container with the respective cap bodies on to move linearly without being rotated over the protrusions and be inserted.

### Claim 2 (depends on 1)

The three-component mixing apparatus as defined in claim 1, wherein a lubricant agent is applied on an inner periphery of the syringe.

### Claim 3 (depends on 1)

The three-component mixing apparatus as defined in claim 1, wherein a lubricant agent is applied on the seal member.

### Claim 4 (depends on 2)

The three-component mixing apparatus as defined in claim 2, wherein the lubricant agent is silicon oil.

### Claim 5 (depends on 1)

The three-component mixing apparatus as defined in claim 1, wherein the connecting part for the second drug container and the connecting part for the third drug container that are formed on the infusion-needle connector are each provided with a needle member.

### Claim 6 (depends on 1)

The three-component mixing apparatus as defined in claim 1, wherein said first drug is powder, said second drug is a liquid, and said third drug is a liquid.

### Claim 7 (depends on 1)

A three-component mixing adhesive kit comprising the three-component mixing apparatus as defined in claim 1, disassembled in a container box.

### Claim 8 (depends on 3)

The three-component mixing apparatus as defined in claim 3, wherein the lubricant agent is silicon oil.
