In order to monitor the pressure data of the infusion tube 21 where the sensor 23 is located when the infusion set roller 24 is closed and opened, the infusion set roller 24 and the sensor 23 need to be arranged on the same side of the pump device 221.
Optionally, the signal processor 25 is configured to: monitoring the state of the infusion apparatus roller, wherein the state comprises the closing of the infusion apparatus roller; acquiring an instantaneous pressure value of the infusion tube 21 where the sensor 23 is located when the infusion set roller is closed; and calibrating target pressure data according to the instantaneous pressure value, wherein the target pressure data is the pressure data monitored during the closing period of the infusion set roller.

Optionally, the signal processor 25 is further configured to: judging whether the pressure data has downward mutation; if downward mutation occurs, acquiring a first inflection point value during downward mutation, and determining the first inflection point value as the instantaneous pressure value; replacing the target pressure data with the instantaneous pressure value.

Wherein the instantaneous pressure value is a specific data on a change curve of gradual attenuation of the pressure data along with the monitoring time. The pressure data monitored during the closing of the infusion set roller 24 is replaced by the instantaneous pressure value, and the calibration method ensures that the monitored pressure data is changed smoothly, and avoids monitoring abnormally changed pressure data caused by closing the infusion set roller 24.
During the process of replacing the pressure data monitored during the closing of the infusion apparatus roller 24 with the instantaneous pressure value, the state of the infusion apparatus roller 24 needs to be monitored in real time to determine whether the infusion apparatus roller 24 is opened, if the opening of the infusion apparatus roller 24 is monitored, the operation of replacing the monitored pressure data with the instantaneous pressure value is stopped, and the pressure data is continuously monitored; or if the opening of the infusion apparatus roller 24 is monitored, after a preset time period for opening the infusion apparatus roller 24, the operation of replacing the monitored pressure data with the instantaneous pressure value is stopped, and the pressure data is continuously monitored.

If a sudden upward sudden change of the change curve is monitored, as shown in fig. 10, the pressure data suddenly changes upward from the point P, which indicates that the infusion set roller 24 corresponding to the point P is turned on, and the time point of the sudden upward change corresponds to the time point when the infusion set roller 24 is turned on.
Optionally, whether a downward mutation or an upward mutation occurs may be determined by the slope of the curve, for example, if the slope is smaller than a first preset threshold, the downward mutation is indicated, wherein the first preset threshold is-40, -50, -60, and the like, which are set and modified according to actual situations; if the slope is greater than a second predetermined threshold, it indicates that an upward jump occurs, wherein the second predetermined threshold 40, 50, 60, etc. are set and modified according to actual conditions.

If the sensitivity of the sensor is low, the data from the point P to the point M is likely to be vertically abrupt, and the calibration of the monitored pressure data is stopped directly when the infusion set roller 24 is turned on. If the sensitivity of the sensor is high, the data from point P to point M may be abruptly sloped, and it is necessary to stop calibrating the monitored pressure data after a preset time period for turning on the infusion set roller 24.
