Abstract

Claims (19)

1 . A method of enabling pre-filling of custom IV bags, the method comprising:

providing an electronic fluid transfer system configured to receive instructions from a user regarding an amount of fluid to be transferred from one or more source containers into an IV bag;

providing a pre-assembled IV assembly comprising an IV bag, providing a tubing permanently bonded in fluid communication with the IV bag, the tubing-bonding occurring before the pre-assembled IV assembly is provided to a user, such that the user is not required to attach the tubing to the IV assembly, and providing a connector permanently bonded to the tubing, the connector-bonding occurring before the pre-assembled IV assembly is provided to a user, such that the user is not required to attach the closeable connector to the tubing, the connector comprising an open position and a closed position for providing a selectively accessible closed fluid system, and the tubing having a length of at least about 2½ feet so as to be configured to be extendable from a hanging position on a pole stand to a connector attached to a patient or to an infusion pump and further configured to provide fluid communication to the IV bag for both filling of the IV bag and delivery of the fluid from the IV bag to the patient;

instructing a user to connect the connector of the IV assembly to the electronic fluid transfer system, placing the IV assembly in fluid communication with the electronic fluid transfer system;

instructing a user to transfer fluid from one or more source containers in the electronic fluid transfer system to the IV bag, such that the fluid is transferred by the electronic fluid transfer system through the connector, then through the tubing, then into the IV bag, to produce a pre-primed IV assembly with fluid extending from the connector through the tubing and into the IV bag.

2 . The method of claim 1 , wherein the pre-assembled IV assembly comprises a drip chamber positioned between the tubing and the IV bag.

3 . The method of claim 1 , wherein the connector is a closeable connector.

4 . The method of claim 1 , wherein the connector is a resealable connector.

5 . The method of claim 4 , wherein the connector is a needleless connector.

6 . The method of claim 1 , wherein the connector is a male connector.

7 . The method of claim 5 , wherein the connector is a female connector.

8 . The method of claim 6 , wherein the male connector is configured to prevent conveyed or residual fluid from leaking out after disconnection.

9 . The method of claim 1 , wherein the electronic fluid transfer system comprises a drive motor.

10 . The method of claim 9 , wherein the electronic fluid transfer system comprises a driving mechanism.

11 . The method of claim 10 , wherein the electronic fluid transfer system comprises a microprocessor.

12 . The method of claim 11 , wherein the electronic fluid transfer system comprises a memory.

13 . The method of claim 12 , wherein the electronic fluid transfer system comprises communications hardware and software to enable electronic communication with a network.

14 . The method of claim 12 , wherein the electronic fluid transfer system comprises an electronic display.

15 . The method of claim 12 , wherein the electronic fluid transfer system comprises a user input system.
