Some embodiments disclosed herein related to a device for transferring precise amounts of fluid from at least one source container to a at least one target container. In some embodiments, the fluid is first transferred from the source container (e.g., a vial) through a connector to an intermediate measuring container (e.g., a syringe). In some embodiments air can pass through an air inlet and enter the vial to compensate for the volume of fluid withdrawn from the vial. An air check valve or a bag or a filter can prevent the fluid from escaping through the air inlet. The precisely measured amount of fluid can then be transferred from the intermediate measuring container to the target container (e.g., an IV bag). In some embodiments the connector can include a source check valve and a target check valve to direct fluid first from the source container to the intermediate measuring container and then from the intermediate measuring container to the target container. Some embodiments of the device can include a motor and a controller for automatically actuating a plunger of the syringe to transfer the desired amount of fluid.

1. A method of providing a fluid transfer module for use with a substantially entirely closed system for the transfer of medical fluids between or among different medical fluid containers by an electronically controlled fluid dispensing system, the method comprising: (a) providing a fluid transfer module configured to be removably attachable to an electronically controlled fluid dispensing system, the fluid transfer module comprising: (i) a first interface configured to be connected in fluid communication with a fluid source container, the first interface comprising a first selectively openable and closeable aperture that is configured to substantially entirely prevent fluid within the fluid transfer module from escaping through the first aperture when the first aperture is closed;(ii) a second interface configured to be connected in fluid communication with a fluid destination container, the second interface comprising a second selectively openable and closeable aperture that is configured to substantially entirely prevent fluid within the fluid transfer module from escaping through the second aperture when the second aperture is closed;(iii) an intermediate container, or an intermediate interface configured to be connected to an intermediate container;(iv) a first valve configured to permit the passage of fluid from the fluid source container to the intermediate container and configured to generally obstruct the passage of fluid from the intermediate container to the fluid source container; and(v) a second valve configured to permit the passage of fluid from the intermediate container to the fluid destination container and to generally obstruct the passage of fluid from the fluid destination container to the intermediate container; and(b) instructing a user to attach the fluid transfer module to the electronically controlled fluid dispensing system to assist in transferring fluid;wherein an interaction portion of the fluid transfer module comprises a generally transparent housing portion and a generally opaque, generally rigid valve portion, the interaction portion being connected to the fluid transfer module such that the interaction portion is configured to permit the electronically controlled fluid dispensing system to detect that the second aperture is open when the valve portion moves into a light path in the electronically controlled fluid dispensing system; andwherein the fluid transfer module is configured to substantially prevent fluid within the fluid transfer module from escaping upon disconnection of the fluid transfer module from the fluid source container and the fluid destination container. 2. The method of claim 1, further comprising providing the electronically controlled fluid dispensing system. 3. The method of claim 1, further comprising providing the fluid source container. 4. The method of claim 3, wherein the fluid source container is a medicinal vial. 5. The method of claim 1, further comprising providing a vial adapter configured to removably connect to the first interface between the fluid transfer module and the fluid source container, wherein the vial adapter comprises a selectively openable and closeable fluid passage that substantially prevents fluid within the vial adapter from escaping after the vial adapter is detached from the first interface. 6. The method of claim 1, further comprising providing the fluid destination container. 7. The method of claim 6, wherein the fluid destination container is an IV bag. 8. The method of claim 7, further comprising providing a selectively closeable fluid connector configured to removably connect to the second interface between the fluid transfer module and the IV bag, wherein the selectively closeable fluid connector substantially prevents fluid within the IV bag from escaping after the IV bag is detached from the second interface. 9. The method of claim 2, wherein the electronically controlled fluid dispensing system comprises a beam emitter and a beam detector, and wherein the electronically controlled fluid dispensing system detects that the second aperture is open by detecting that a beam emitted from the beam emitter has not been detected by the beam detector. 10. The method of claim 1, wherein a second interaction portion of the fluid transfer module is configured to permit the electronically controlled fluid dispensing system to detect that at least a portion of the fluid transfer module is attached to the electronically controlled fluid dispensing system, and wherein the second interaction portion of the fluid transfer module comprises a generally opaque outer housing. 11. The method of claim 1, wherein the interaction portion of the fluid transfer module comprises a closeable male luer connector. 12. The method of claim 1, wherein the fluid transfer module is configured to be disposable. 13. The method of claim 1, further comprising connecting the first interface to the fluid source container, or further comprising connecting the second interface to the fluid destination container. 14. The method of claim 2, wherein the electronically controlled fluid dispensing system is capable of detecting air bubbles in the fluid transfer module. 15. The method of claim 1, wherein the first interface is a closeable male luer connector, or wherein the second interface is a closable male luer connector. 16. The method of claim 1, wherein the fluid transfer module is configured to transfer chemotherapy fluids. 17. The method of claim 1, further comprising providing the intermediate container configured to connect to the intermediate interface. 18. The method of claim 1, wherein the fluid transfer module comprises the intermediate container. 19. The method of claim 1, wherein the first valve is integrally formed with the second valve as a single unitary component. 20. The method of claim 1, wherein the second interface comprises a valve member movable between a closed position and an open position, the valve member configured to be in the open position when the fluid destination container is attached to the second interface, and the valve member configured to close automatically when the fluid destination container is detached from the second interface. 21. The method of claim 2, wherein the light path in the electronically controlled fluid dispensing system is an infrared light path.
