Abstract

Fluid transfer systems are disclosed that can be configured to transfer precise amounts of fluid from a source container to a target container. The fluid transfer system can have multiple fluid transfer stations for transferring fluids into multiple target containers or for combining different types of fluids into a single target container to form a mixture. The fluid transfer system can include a pump and a destination sensor, such as a weight sensor. The fluid transfer system can be configured to flush remaining fluid out of a connector to reduce waste, using air or a flushing fluid.

Claims (25)

1. A method of using an electronic medical fluid transfer system with a fume hood, the method comprising:

providing a fume hood comprising a partially enclosed ventilation area and an exhaust duct;

providing an electronic medical fluid transfer station being separate from the fume hood, the electronic medical fluid transfer station comprising:

an electronic controller,

a motor, and

a sensor being configured to detect a presence of a connector of the electronic medical fluid transfer;

positioning the electronic medical fluid transfer station within the partially enclosed ventilation area of the fume hood;

attaching a source container to the electronic medical fluid transfer station;

attaching a destination container to the electronic medical fluid transfer station;

attaching a disposable tubing with a pump to the electronic medical fluid transfer station such that the pump is functionally coupled with the motor of the electronic medical fluid transfer station;

activating the fume hood to produce a flow of air through the exhaust duct; and

utilizing the electronic controller of the electronic medical fluid transfer station to transfer medical fluid from the source container to the destination container.

2. The method of claim 1 , wherein the disposable tubing is a fluid transfer module.

3. The method of claim 2 , wherein the fluid transfer module includes a syringe.

4. The method of claim 1 , wherein the electronic medical fluid transfer station is generally surrounded by walls of the fume hood on at least three sides.

5. The method of claim 1 , wherein the flow of air prevents or reduces particles from escaping.

6. The method of claim 1 , wherein the electronic medical fluid transfer station further comprises a camera being configured to capture and store one or more images to record information regarding a fluid transfer.

7. The method of claim 1 , wherein the electronic medical fluid transfer station further comprises an electronic communication interface.

8. The method of claim 7 , wherein the communication interface is configured to communicate with a hospital information system.

9. The method of claim 2 , wherein the fluid transfer module comprises fluid connectors.

10. The method of claim 2 , wherein the fluid transfer module comprises valving.

11. The method of claim 10 , wherein the valving comprises two discrete valves.

12. The method of claim 1 , wherein the fume hood is configured to produce flow of air selectively during one or more phases of use of the electronic fluid transfer module.

13. The method of claim 12 , wherein the fume hood is further configured to produce flow of air when at least one of engaging or disengaging the destination container.

14. The method of claim 12 , wherein the fume hood is further configured to produce flow of air when at least one of engaging or disengaging connectors of the fluid tubing.
