Abstract

An intravascular port access device includes a first component having a chamber configured to attach reversibly to an intravenous line port. A second component reversibly attaches to the first component and contains a disinfecting agent and an applicator material. The second component is configured to be reversibly received over external surfaces of the intravenous line port. A method of cleansing an intravenous line port includes providing a port cleaning device having a first component with a chamber containing a first cleaning agent. A second component includes a second cleaning agent. A third component has a microbiocidal agent and is reversibly attached to the first component. The second component is removed from the device, the external surfaces of the port are contacted with the second cleaning agent, the first cleaning agent is ejected from the chamber into the port, and the third component is used to cap the port.

Claims

1. A method of administering an agent into an intravascular line port, comprising:

providing a port access device comprising;

a first component having a chamber comprising an agent to be administered into an intravascular line port;

a second component comprising a cleaning agent; and

a third component comprising a microbiocidal agent reversibly attached to the first component;

removing the second component from the device;

contacting external surfaces of the port with the second cleaning agent;

injecting the agent to be administered from the chamber into the port;

removing the third component from the device; and

capping the port with the third component.

2. The method of claim 1 wherein the agent to be administered is selected from the group consisting of an anticoagulant, an acidic solution, a basic solution, and a lipolytic agent.

3. The method of claim 1 wherein the first component is a syringe device.

4. The method of claim 1 wherein the first component comprises a collapsible chamber housing.

5. The method of claim 4 wherein the first component further comprises a slideable valve and a delivery channel.
