Abstract

An example of a method of enabling medical fluid transfer between a source container and a destination container can comprise the steps of providing a closed-system fluid transfer module comprising a first closeable, resealable medical connector and a second closeable, resealable medical connector, a multidirectional fluid control valve with a driving interface configured to interface with an electromechanical driver of an electronic medical fluid transfer device, and an intermediate container or an intermediate pumping region; and instructing a user to couple the closed-system fluid transfer module to the electronic medical fluid transfer device.

Claims

1. A medical fluid transfer module that is configured to be removably coupled to an electronic medical fluid transfer device to facilitate the transfer of medical fluids from a source container to a destination container, the electronic medical fluid transfer device comprising a first electromechanical driver, a second electromechanical driver, and an attachment portion configured to couple with the medical fluid transfer module, the medical fluid transfer module comprising:

a first closeable, resealable medical connector and a second closeable, resealable medical connector;

a multidirectional flow-control valve with a rotatable driving interface configured to interface with a first electromechanical driver of an electronic medical fluid transfer device, the multidirectional flow-control valve comprising a plurality of functional positions to enable a selection among a plurality of different fluid pathways within the medical fluid transfer module, the rotatable driving interface being further configured to rotate to selectively transition between the plurality of different fluid pathways; and

an intermediate container configured to be coupled with an attachment portion of the electronic medical fluid transfer device and configured to interface with a second electromechanical driver of the electronic medical fluid transfer device,

wherein the rotatable driving interface is further configured to be rotatable relative to the intermediate container such that the intermediate container may remain stationary and remain interfaced with the second electromechanical driver of the electronic medical fluid transfer device while the rotatable driving interface selectively transitions between the plurality of different fluid pathways, and

wherein the plurality of different fluid pathways are configured to contain liquid within the medical fluid transfer module in a closed system when the medical fluid transfer module is not attached to the electronic medical fluid transfer device.

2. The combination of the medical fluid transfer module of claim 1 and the electronic medical fluid transfer device.

3. The medical fluid transfer module of claim 1, wherein the rotatable driving interface comprises a shape that is configured to be complementary with or generally match or correspond with a driving interface of the electromechanical driver of the electronic medical fluid transfer device.

4. The medical fluid transfer module of claim 1 further comprising a valve handle configured to be manipulated to actuate the multidirectional flow-control valve to selectively transition between the plurality of different fluid pathways.

5. The medical fluid transfer module of claim 1, wherein the rotatable driving interface is removably engaged with the electronic medical fluid transfer device.

6. A method of enabling medical fluid transfer between a source container and a destination container, the method comprising the steps of:

providing a closed-system fluid transfer module comprising;

a first closeable, resealable medical connector and a second closeable, resealable medical connector,

a multidirectional fluid control valve with a rotatable driving interface configured to interface with a first electromechanical driver of an electronic medical fluid transfer device, and

an intermediate container or an intermediate pumping region configured to be coupled with an attachment portion of the electronic medical fluid transfer device and configured to interface with a second electromechanical driver of the electronic medical fluid transfer device,

wherein the rotatable driving interface is further configured to be rotatable relative to the intermediate container or the intermediate pumping region such that the intermediate container or the intermediate pumping region may remain interfaced with a second electromechanical driver of the electronic medical fluid transfer device while the rotatable driving interface selectively transitions between the plurality of different fluid pathways; and

wherein the closed-system fluid transfer module is configured to couple with the electronic medical fluid transfer device.

7. The method of claim 6 further comprising the step of providing the electronic medical fluid transfer device.

8. The method of claim 6, wherein the rotatable driving interface is removably engaged with the electronic medical fluid transfer device.
