Abstract

This disclosure relates to preventing over-delivery of a drug and related systems and methods. In certain aspects, a method is performed by a data processing apparatus. 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.

First claim

What is claimed is:

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 whether the initial amount of fluid in the drug vial approximately equals the desired amount of fluid; and
automatically sending a signal to the pump via a control unit to stop pumping fluid upon determining 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 the initial amount of fluid provided to the drug delivery device is determined by a total amount of fluid in a drug vial.

4. The method of claim 3 , wherein detecting whether the initial amount of fluid corresponds to the desired amount of fluid comprises detecting a presence of air in a drug delivery line of the drug delivery device.

5. The method of claim 4 , further comprising upon determination of the presence of air in the drug delivery line, sending a signal to the pump to increase a pumping speed of the pump.

6. A dialysis machine and a computer storage medium encoded with a computer program, the program comprising instructions that when executed by one or more computers the one or more computers to perform operations comprising: receiving, 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, 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 whether the initial amount of fluid in the drug vial approximately equals the desired amount of fluid; and automatically sending a signal to the pump via a control unit to stop pumping fluid upon determining that the delivered amount of fluid satisfies the desired amount of fluid to be delivered.

7. The dialysis machine and the computer storage medium of claim 6 , 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.

8. The dialysis machine and the computer storage medium of claim 6 , wherein the initial amount of fluid provided to the drug delivery device is determined by a total amount of fluid in a drug vial.

9. The dialysis machine and the computer storage medium of claim 8 , wherein detecting whether the initial amount of fluid corresponds to the desired amount of fluid comprises detecting a presence of air in a drug delivery line of the drug delivery device.

10. The dialysis machine and the computer storage medium of claim 9 , further comprising upon determination of the presence of air in the drug delivery line, sending a signal to the pump to increase a pumping speed of the pump.
