摘要： A syringe pump is provided. The syringe pump includes a pump body, a control system, a transmission mechanism, and a propulsion mechanism. The transmission mechanism includes a bracket, a propulsion driving motor, a screw rod, a sliding seat, a half nut, and a clutch driving assembly. The propulsion driving motor configured to drive the screw rod to rotate, the clutch driving assembly is disposed on the sliding seat, and configured to drive the half nut and the screw rod to be engaged and disengaged from each other. The propulsion mechanism includes a connecting rod, a pushing block, a pressure sensing assembly, and a clutch switch. The pressure sensing assembly is disposed on the pushing block and configured to detect pressure of a piston rod of a syringe. The clutch switch is disposed on the pushing block and electrically connected to the clutch driving assembly.
