This disclosure relates to preventing over-delivery of a drug and related systems and methods. The method includes receiving, from a drug delivery device, information pertaining to a desired amount of fluid to be delivered by the drug delivery device and receiving information pertaining to a delivered amount of a fluid that has been delivered by the drug delivery device. The method also includes determining that the delivered amount satisfies a predetermined threshold amount and in response to the determination, detecting whether an initial amount of fluid provided to the drug delivery device corresponds to the desired amount of fluid to be delivered.

1. A method performed by a data processing apparatus, the method comprising: receiving at the data processing apparatus, from a drug delivery device that is part of a dialysis machine, information pertaining to a desired amount of fluid to be delivered by the drug delivery device;receiving at the data processing apparatus, from a pump, information pertaining to an amount of a fluid that has been delivered by the drug delivery device from a drug vial having an initial amount of fluid provided to the drug delivery device;determining that the amount delivered by the pump has reached a predetermined threshold amount, the threshold amount being less than the desired amount;in response to the determination that the threshold amount has been delivered, detecting, by a signal from a bubble detector, a presence or absence of air in a drug delivery line of the drug delivery device indicating whether delivery of the threshold amount has emptied the drug vial, and thereby determining whether the initial amount of fluid in the drug vial approximately equals the desired amount of fluid; andupon determination of the presence of air in the drug delivery line, automatically sending a signal to the pump via a control unit of the drug delivery device to increase a pumping speed of the pump, and upon determination of the absence of air in the drug delivery line, automatically sending a signal to the pump via the control unit to stop pumping fluid, wherein the signal to stop pumping fluid indicates a determination that the delivered amount of fluid satisfies the desired amount of fluid to be delivered. 2. The method of claim 1, further comprising: sending an alert to a user interface that the desired amount of fluid does not approximately equal the initial amount of fluid provided. 3. The method of claim 1, wherein detecting the initial amount of fluid further comprises detecting the presence of air for a threshold amount of time. 4. The method of claim 1, wherein the threshold amount is a portion of the initial amount of fluid. 5. A dialysis system comprising: a dialysis machine;a control unit comprising one or more processors;a drug delivery line connected to the dialysis machine;a bubble detector; anda computer-readable medium coupled to the control unit having instructions stored thereon which, when executed by the one or more processors, cause the one or more processors to perform operations comprising: receiving, from a drug delivery device that is part of the dialysis machine, information pertaining to a desired amount of fluid to be delivered by the drug delivery device;receiving, from a pump, information pertaining to an amount of a fluid that has been delivered by the drug delivery device from a drug vial having an initial amount of fluid provided to the drug delivery device;determining that the amount delivered by the pump has reached a predetermined threshold amount, the threshold amount being less than the desired amount;in response to the determination that the threshold amount has been delivered, detecting, by a signal from the bubble detector, a presence or absence of air in the drug delivery line of the drug delivery device indicating whether delivery of the threshold amount has emptied the drug vial, and thereby determining whether the initial amount of fluid in the drug vial approximately equals the desired amount of fluid; andupon determination of the presence of air in the drug delivery line, automatically sending a signal to the pump via a control unit of the drug delivery device to increase a pumping speed of the pump, and upon determination of the absence of air in the drug delivery line, automatically sending a signal to the pump via the control unit to stop pumping fluid, wherein the signal to stop pumping fluid indicates a determination that the delivered amount of fluid satisfies the desired amount of fluid to be delivered. 6. The system of claim 5, further comprising: sending an alert to a user interface that the desired amount of fluid does not approximately equal the initial amount of fluid provided. 7. The system of claim 5, wherein detecting the initial amount of fluid further comprises detecting the presence of air for a threshold amount of time. 8. The system of claim 5, wherein the threshold amount is a portion of the initial amount of fluid.
