Abstract
Systems and methods for the transfer of medical fluid are provided. A medical fluid transfer system may comprise a pump configured to transfer fluid through a tube assembly having a first connector configured to couple to a source container and a second connector configured to couple to a target container. The medical fluid transfer system may also comprise a destination sensor configured to output information about the target container. The medical fluid transfer system may further comprise a control system configured to operate the pump based on an operational setting associated with fluid volume; receive measurement data representing a measurement of the target container by the destination sensor, and adjust the operational setting based on an observed volume of fluid transferred to the target container.
Claims19
A medical fluid transfer system comprising:
- a pump comprising a rotor with one or more lobes, wherein the pump is configured to transfer fluid through a tube assembly having a first connector configured to couple to a source container and a second connector configured to couple to a target container;
- a destination sensor configured to output information about the target container;
- and
- a control system configured to:
- receive an instruction to transfer a desired volume of a medical fluid to the target container;
- operate the pump based on the instruction and an operational setting associated with a first quantity of rotations that the rotor is to be rotated for transfer of a fluid volume of the medical fluid;
- receive measurement data representing a measurement of the target container by the destination sensor;
- determine a difference between a transferred volume of the medical fluid and the desired volume of the medical fluid based at least partly on the measurement data and a fluid property of the medical fluid;
- adjust the operational setting based on the difference to a second quantity of rotations that the rotor is to be rotated for transfer of the fluid volume of the medical fluid;
- and
- operate the pump based on the operational setting that has been adjusted.
A method for calibrating a medical fluid transfer system, the method comprising:
- under control of a control system of the medical fluid transfer system, the control system comprising one or more computer processors configured to execute specific instructions:
- receiving an instruction to transfer a desired volume of a medical fluid to a target container;
- operating a pump of the medical fluid transfer system based on the instruction and an operational setting, wherein the pump comprises a rotor and one or more lobes, and wherein the operational setting is associated with a first quantity of rotations that the rotor is to be rotated for transfer of a fluid volume of the medical fluid;
- receiving measurement data representing a measurement of the target container by a destination sensor;
- determining a difference between a transferred volume of the medical fluid and the desired volume of the medical fluid based at least partly on the measurement data and a fluid property of the medical fluid;
- and
- adjusting the operational setting based on the difference to a second quantity of rotations that the rotor is to be rotated for transfer of the fluid volume of the medical fluid.
