Abstract

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 In some embodiments air can pass through an air inlet and enter the vial to compensate for the volume of fluid withdrawn from the vial.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.

Claims

1. A medical fluid transfer system for the transfer of medical fluids between different medical fluid containers, the medical fluid transfer system comprising:

a remote management device being configured to;

send one or more fluid transfer instructions comprising information about a fluid transfer between a source container that is configured to contain the fluid before the fluid transfer and a target container that is configured to contain the fluid before the fluid is administered to a patient, and

receive one or more results of a fluid transfer process; and

a fluid dispensing device that engages a fluid transfer module, the fluid transfer module comprising a syringe with a plunger and an interface that is selectively openable and closeable, the fluid transfer module being configured to couple to the source container in a first connection step and to couple to the target container in a second connection step to provide a closed medical fluid transfer process, the fluid dispensing device comprising;

a connector configured to couple to the fluid transfer module,

an actuator base configured to engage the plunger of the fluid transfer module to transfer the fluid from the source container and into the syringe through the fluid transfer module in a first transfer step, and separately to transfer the fluid from the syringe into the target container through the fluid transfer module in a second transfer step, and

a controller comprising a communication interface, the controller configured to;

receive the one or more fluid transfer instructions from the remote management device via the communication interface,

operate the actuator base to transfer the fluid from the source container and into the syringe through the fluid transfer module in the first transfer step, and separately to transfer the fluid from the syringe into the target container in the second transfer step using the one or more fluid transfer instructions, and

send the one or more results of the fluid transfer process to the remote management device via the communication interface.

2. The medical fluid transfer system of claim 1, wherein the one or more fluid transfer instructions comprises at least one of a specified volume of the fluid and a specified type of the fluid.

3. The medical fluid transfer system of claim 1, wherein the one or more results comprises at least one of an amount of fluid transfer, a type of fluid transfer, an error message, an alert.

4. The medical fluid transfer system of claim 1 further comprising a user interface configured to receive the one or more fluid transfer instructions from a user.

5. The medical fluid transfer system of claim 4, wherein the user interface comprises a touch screen display.

6. The medical fluid transfer system of claim 1, wherein the remote management device is configured to send one or more fluid transfer instructions to one or more fluid dispensing devices.

7. The medical fluid transfer system of claim 1 further comprising an air detector configured to detect air in a fluid pathway of the fluid transfer module.

8. The medical fluid transfer system of claim 7, wherein the fluid transfer module comprises a sensor region configured to align with the air detector and configured to permit the air detector to detect air in the fluid passageway of the fluid transfer module.

9. The medical fluid transfer system of claim 7, wherein the controller is further configured to:

receive information from the air detector indicating whether or not air is present in the fluid passageway of the fluid transfer module; and

operate the syringe pump based on the information received from the air detector,

wherein the controller prevents the fluid dispensing device from attempting to transfer fluid when air is detected.

10. The medical fluid transfer system of claim 1, wherein the fluid dispensing device further comprises a destination sensor configured to detect whether or not the target container is connected to the fluid transfer module.

11. The medical fluid transfer system of claim 10, wherein the destination sensor is further configured to output information indicating whether or not the target container is connected.

12. The medical fluid transfer system of claim 1, wherein the interface of the fluid transfer module comprises a closeable connector.

13. The medical fluid transfer system of claim 12, wherein the closable connector comprises a closable male connector.

14. The medical fluid transfer system of claim 1, wherein the fluid transfer module further comprises at least one valve.

15. The medical fluid transfer system of claim 14, wherein the at least one valve of the fluid transfer module is configured to permit the fluid to move from the source container to the syringe and to inhibit to the fluid from moving from the syringe to the source container.

16. The medical fluid transfer system of claim 1, wherein the medical fluid transfer system allows the fluid transfer module to be coupled to both the source container and the target container at the same time.
