An infusion pump is an optomechanical and electrical integrated medical device, which generally includes core functions such as "flow control", "signal detection", "human-computer interaction", "sound and light alarms" and "calculation, task management and decision-making". The flow control part is generally composed of a stepper motor and its driver, a linear peristaltic pump body, an infusion pump pipeline and its clamping mechanism. When working, the peristaltic pump body is controlled to rotate at the calculated speed according to the infusion speed set by the user and the pre-calibrated pipeline parameters, so as to achieve the purpose of controlling the infusion speed.
