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

1. A fluid transfer module for use with an electronically controlled fluid dispensing system for the transfer of medical fluids between or among different medical fluid containers, the fluid transfer module comprising:

a three-way connector comprising;

a first interface configured to be connected in fluid communication with a fluid source container,

a second interface configured to be connected in fluid communication with a fluid target container, and

an intermediate interface configured to be in fluid communication with a syringe pump that is configured to transfer fluid through the three-way connector; and

a fluid switch having a first configuration configured to open a first fluid pathway between the fluid source container and the intermediate interface, the fluid switch having a second configuration configured to close the first fluid pathway between the fluid source container and the intermediate interface and to open a second fluid pathway between the intermediate interface and the second interface, wherein the fluid switch is configured to interact with an actuator of the electronically controlled fluid dispensing system that is configured to move the fluid switch between the first configuration and the second configuration,

wherein the fluid transfer module is configured to be removeably attachable by a user to the electronically controlled fluid dispensing system such that, when the fluid transfer module is connected to the electronically controlled fluid dispensing system, a camera on the electronically controlled fluid dispensing system can capture an image of at least a portion of the fluid transfer module, and

wherein 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 target container.

2. A combination of the fluid transfer module of claim 1 with the electronically controlled fluid dispensing system.

3. A combination of the fluid transfer module of claim 1 with the syringe pump.

4. A combination of the fluid transfer module of claim 1 with the fluid target container.

5. The fluid transfer module of claim 1, wherein the fluid switch comprises a stopcock.

6. The fluid transfer module of claim 1, wherein the first interface comprises a first closable connector configured to removably couple to the fluid source container, and wherein the second interface comprises a second closable connector configured to removably couple to the fluid target container.

7. The fluid transfer module of claim 6, wherein the first closable connector is a closable male connector and the second closable connector is a closable male connector.

8. The fluid transfer module of claim 1, wherein the intermediate interface comprises a syringe interface configured to be connected to an intermediate container.

9. The fluid transfer module of claim 1, wherein the fluid transfer module further comprises a sensor region positioned between the fluid switch and the intermediate interface such that the sensor region is configured to permit a bubble sensor of the electronically controlled fluid dispensing system to detect air in the fluid passageway of the fluid transfer module.

10. The fluid transfer module of claim 1, wherein the fluid transfer module is configured to interact with a destination sensor of the electronically controlled fluid dispensing system, and wherein the destination sensor is configured to detect whether or not the fluid target container is connected to the second interface and to output information indicating whether or not the target container is connected.

11. The fluid transfer module of claim 10, wherein the destination sensor is configured to detect whether the second interface is open.

12. The fluid transfer module of claim 1, wherein the control system is configured to receive instructions from a remote source.

13. A fluid transfer system comprising:

an electronically controlled fluid dispensing system; and

the fluid transfer module of claim 1 removably attached to the electronically controlled fluid dispensing system.

14. The fluid transfer system of claim 13, wherein the electronically controlled fluid dispensing system comprises a beam emitter and a beam detector, and wherein the electronically controlled fluid dispensing system is capable of detecting air bubbles in the fluid transfer module.

15. The fluid transfer system of claim 13, wherein the electronically controlled fluid dispensing system comprises a bubble sensor configured to align with a sensor region of the fluid transfer module for detecting air in the fluid passageway of the fluid transfer module.

16. The fluid transfer system of claim 13, wherein the electronically controlled fluid dispensing system comprises:

one or more sensors configured to detect whether or not the three-way connector is attached to the electronically controlled fluid dispensing system, wherein the control system is configured to not allow fluid transfer when the three-way connector is not detected; and

a mounting module configured to align the three-way connector with the one or more sensors.

17. The fluid transfer system of claim 13, wherein the electronically controlled fluid dispensing system comprises one or more cameras configured to capture images of at least a portion of the fluid transfer module to document one or more steps of a fluid transfer process performed by the electronically controlled fluid dispensing system.

18. A method of enabling the transfer of fluid using a medical fluid transfer system, the method comprising:

providing a fluid transfer module comprising;

a three-way connector comprising;

a first interface configured to be connected in fluid communication with a fluid source container,

a second interface configured to be connected in fluid communication with a fluid target container, and

an intermediate interface configured to be in fluid communication with a syringe pump that is configured to transfer fluid through the three-way connector; and

a fluid switch having a first configuration configured to open a first fluid pathway between the fluid source container and the intermediate interface, the fluid switch having a second configuration configured to close the first fluid pathway between the fluid source container and the intermediate interface and to open a second fluid pathway between the intermediate interface and the second interface, wherein the fluid switch is configured to interact with an actuator of the medical fluid transfer system that is configured to move the fluid switch between the first configuration and the second configuration,

wherein the fluid transfer module is configured to be removeably attachable by a user to the medical fluid transfer system such that, when the fluid transfer module is connected to the medical fluid transfer system, a camera on the medical fluid transfer system can capture an image of at least a portion of the fluid transfer module, and

wherein 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 target container.

19. The method of claim 18, wherein the fluid switch comprises a stopcock.

20. The method of claim 18, wherein the first interface comprises a first closable connector configured to removably couple to the fluid source container, and wherein the second interface comprises a second closable connector configured to removably couple to the fluid target container.

21. The method of claim 18, wherein the intermediate interface comprises a syringe interface configured to be connected to an intermediate container.

22. The method of claim 18, wherein the fluid transfer module further comprises a sensor region positioned between the fluid switch and the intermediate interface such that the sensor region is configured to permit a bubble sensor of the electronically controlled fluid dispensing system to detect air in the fluid passageway of the fluid transfer module.

23. The method of claim 18 further comprising providing a medical fluid transfer system.
