Operating methods, storage media, computer equipment, and syringe pumps
By establishing a linear equation between syringe specifications and flow rate in the infusion pump, and using voltage changes from a pressure sensor to detect extension tube detachment, the problem of inaccurate extension tube detection in infusion pumps is solved, enabling more precise alarms and ensuring patient safety.

Abstract
This application discloses an operating method for an injection pump, a storage medium, a computer device, and the injection pump itself. The operating method includes: determining a dislodgement alarm threshold based on the syringe specifications and a set flow rate; determining the relationship between the voltage drop rate of a pressure sensor and the dislodgement alarm threshold; and issuing an extension tube dislodgement alarm in response to a voltage drop rate greater than or equal to the dislodgement alarm threshold. Through this method, the injection pump operating method provided by this application can obtain corresponding dislodgement alarm thresholds based on syringe specifications and flow rates, which helps to more accurately detect extension tube dislodgement and reduces the probability of missed or false alarms.
