Medical tubing installation detection

摘要

This disclosure relates to medical tubing installation detection. In certain aspects, a method is performed by a data processing apparatus. The method includes detecting that a tube is incorrectly installed on a drug delivery device by providing an instruction for a motor of the drug delivery device to pump a drug and receiving, after a period of time has passed since providing the instruction for the motor of the drug delivery device to pump the drug, a signal from a fluid detector connected to the tube, the signal indicating an absence of fluid in the tube.

主权项

1. A method performed by a data processing apparatus, the method comprising:
detecting that a tube is incorrectly installed on a drug delivery device by:
receiving a first signal from a fluid detector connected to the tube;determining a first magnitude of the received first signal from the fluid detector;storing the first magnitude of the first signal;receiving, at a later time, a second signal from the fluid detector connected to the tube, a pump connected to the tube active during a time period between receipt of the first signal and receipt of the second signal;determining a second magnitude of the received second signal from the fluid detector;comparing the first magnitude of the received first signal with the second magnitude of the received second signal; anddetermining that the second magnitude is a threshold level greater than the first magnitude, wherein the tube is incorrectly installed on the drug delivery device when the tube is occluded by a door of the drug delivery device being closed on the tube.
