1. A medical fluid transfer system comprising:
- a three-way connector having a first closable connector configured to couple to a source container, a second closable connector configured to couple to a target container, and a syringe interface;
a syringe pump in fluid communication with the syringe interface and configured to transfer fluid through the three-way connector;
a destination sensor configured to detect whether or not the target container is connected to the second closable connector and to output information indicating whether or not the target container is connected;
a fluid switch having a first configuration and a second configuration, wherein the first configuration of the fluid switch opens a fluid pathway between the source container and the syringe pump, and wherein the second configuration of the fluid switch closes the fluid pathway between the source container and the syringe pump;
an actuator configured to toggle the fluid switch between the first and second configurations;
one or more cameras configured to capture images of one or more components to document one or more steps of a fluid transfer process performed by the fluid transfer system; and
a control system configured to;
receive instructions, wherein the instructions comprise a fluid transfer instruction to transfer a specified volume of fluid from the source container to the target container;
operate the syringe pump and actuate the fluid switch to open and close the fluid pathway between the source container and the syringe pump based on the fluid transfer instructions;
receive the information indicating whether or not the target container is connected from the destination sensor; and
operate the syringe pump based on the information received from the destination sensor, wherein the control system prevents the system from attempting to transfer fluid when the target container is not connected.

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.
