## Abstract

A connector for connecting a medical tube set to a medical container, includes a collar connectable to a container, a cap having at least one opening for receiving a tube of a tube set, and an annular seal. The cap is located in the collar between an inner surface of the collar and the seat. The cap is rotatable relative to the collar. The collar includes a generally cylindrical side wall open at its upper and lower ends and an annular flange projects inwardly from the side wall at the upper end. The cap has a disc defining at least one opening and having an outer annular rim which locates between a lower surface of the annular flange on the collar and the seal.

## Claims

### Claim 1

A connector for connecting a medical tube set to a medical container, comprising a collar connectable to a container, a cap comprising at least one opening for receiving a tube of a tube set, and an annular seal, wherein the cap is located in the collar between an inner surface of the collar and the seal, and the cap is rotatable relative to the collar wherein the collar comprises a generally cylindrical side wall open at its upper and lower ends, and an annular flange projects inwardly from the side wall at the upper end, and the cap comprises a disc defining at least one opening and having an outer annular rim, wherein the annular rim locates between a lower surface of the annular flange on the collar and the seal.

### Claim 2 (depends on 1)

A connector is claimed in claim 1, wherein the seal contacts an inner surface of the collar and a surface of the cap.

### Claim 3 (depends on 1)

A connector as claimed claim 1, wherein cylindrical tube receiving portions project from the cap around the or each opening.

### Claim 4 (depends on 1)

A connector as claimed in claim 1, wherein the cap comprises four openings.

### Claim 5 (depends on 4)

A connector as claimed in claim 4, wherein the openings comprise two or more different diameters.

### Claim 6 (depends on 1)

A tube set comprising a connector as claimed in claim 1, wherein the cap comprises four openings and a tube is fitted through each opening.

### Claim 7 (depends on 6)

A tube set as claimed in claim 6, wherein first and second tubes are adapted to supply liquid from a container to which the connector is connected to a medical instrument.

### Claim 8 (depends on 6)

A tube set as claimed in claim 6, wherein a third tube is adapted to pass gas between the container to which the connector is connected and a medical instrument.

### Claim 9 (depends on 6)

A tube set as claimed in claim 6, wherein a fourth tube is adapted to supply gas from an external source to a container to which the connector is connected.
