Description

Intelligent monitoring infusion pump Technical Field The invention relates to the technical field of infusion pumps, in particular to an intelligent monitoring infusion pump. Background Infusion pumps are typically mechanical or electronic control devices that control the infusion rate by acting on an infusion catheter. It is often used in situations where strict control of the amount and dosage of infusion is required, such as in the application of booster drugs, antiarrhythmic drugs, intravenous infusion or intravenous anaesthesia. The patent of publication number CN220046699U discloses an infusion pump, which comprises a main body and a driving device, wherein the driving device comprises a driving part, a cam mechanism and an extrusion mechanism, the cam mechanism comprises a connecting shaft, a first cam, a second cam and a third cam which are arranged on the connecting shaft, the first cam and the third cam are respectively arranged at two sides of the second cam along the axial direction of the connecting shaft, the extrusion mechanism comprises a first extrusion part, a second extrusion part and a third extrusion part, the first extrusion part can extrude a first infusion tube under the drive of the first cam, the second extrusion part can extrude liquid medicine in an extrusion cavity under the drive of the second cam, so that the liquid medicine enters the second infusion tube, and the third extrusion part can extrude the second infusion tube under the drive of the third cam; This structure is when using, and pressure sensor's detection surface can support the pressure second transfer line to detect the hydraulic pressure in the second transfer line, help detecting whether there is the bubble in the second transfer line, when there is the bubble in the second transfer line, pressure sensor can report to the police and indicate, but this structure only realizes detecting pressure and the function of suggestion warning, can't realize quick adjustment pressure and then adjust the function of liquid medicine flow size, and is difficult to eliminate the bubble in the liquid medicine, and is inconvenient when using.
