Providing positive displacement upon disconnection using a connector with a dual diaphragm valve

A method of making a connector, comprising:

• associating a single fluid flow path with the connector, wherein the single fluid flow path is configured for delivering fluid to a person and configured for receiving fluid from a person;
• associating an air chamber with the connector, wherein the air chamber is configured for expelling air from the air chamber when an actuator is inserted into the connector and for receiving air into the chamber when the actuator is removed from the connector;
• and
• associating a valve plug, which has two diaphragms, with the connector, wherein the single fluid flow path is not required to flow through the valve plug and wherein the connector provides positive displacement, at least in part, due to a volume associated with the single fluid flow path decreasing and a volume associated with the air chamber increasing, by returning the valve plug and the two diaphragms to an undeformed state upon removal of the actuator from the connector.

A connector, including:

• a housing that includes a top port;
• a base that includes a bottom port, wherein the housing is securely connected to the base;
• an insert securely connected to the base, wherein the insert is inside a portion of the housing;
• an air chamber;
• a single fluid flow path that includes the top port and the bottom port;
• and
• a valve plug that includes two diaphragms that separate the air chamber from the single fluid flow path, wherein the valve plug is inside a volume formed by portions of the insert and the housing, wherein the single fluid flow path is not required to flow through the valve plug and wherein the connector is configured to provide positive displacement when the valve plug returns to an undeformed state upon removal of an actuator from the top port.
