## Abstract

A breakaway medical tubing connector and method for joining two sections of medical tubing includes a pump side member and a patient side member positioned axially opposite from the pump side member. The patient side member has a first channel disposed within the pump side member and a first valve disposed within the first channel. The pump side member has a second channel disposed within the patient side member and a second valve disposed within the second channel. The first valve may be an active valve and the second valve may be a passive valve. A securing bar may be disposed on the pump side member and a securing arm may be disposed on the patient side member for providing a detachable coupling of the two members.

## Claims

### Claim 1

A method of coupling a detachable line connector, comprising:
aligning a first channel of a pump side member of the detachable line connector with a second channel of a patient side member of the detachable line connector, wherein the pump side member comprises a securing bar and wherein the patient side member comprises a securing arm, and wherein the patient side member further comprises a securing arm guard extending from the patient side member and positioned radially outward from the securing arm, wherein the securing arm guard defines a key hole configured to permit access to the securing arm;
deflecting the securing arm of the patient side member radially inward;
advancing the patient side member and the pump side member towards each other until the first channel and the second channel are in fluid communication;
releasing the securing arm, such that the securing arm of the patient side member engages the securing bar of the pump side member; and
inserting a key into the key hole of the securing arm guard.

### Claim 2 (depends on 1)

The method of claim 1, wherein the step of deflecting the securing arm is via the key.

### Claim 3 (depends on 2)

The method of claim 2, further comprising activating a first valve of the pump side member via a valve activating surface of the patient side member, wherein first valve comprises a diaphragm, and wherein the valve activating surface of the patient side member is axially spaced from the diaphragm while activating the first valve.

### Claim 4 (depends on 1)

The method of claim 1, further comprising receiving a cannula of the patient side member by a toric joint of the pump side member.

### Claim 5 (depends on 1)

The method of claim 1, further comprising sliding the securing arm past the securing bar when the securing arm is manually deflected radially inward.

### Claim 6 (depends on 1)

The method of claim 1, wherein the securing arm and securing bar are positioned to resist coupling when the securing arm is in a neutral position.
