According to the embodiment, the invention discloses an injection pump transmission device and an injection pump adopting the injection pump transmission device, and belongs to the technical scheme in the field of injection pumps. The injection pump transmission device comprises a screw rod, a transmission rod, a guide rod, a driving device, a pushing head, a transmission sliding block and a clutch control mechanism, wherein the screw rod, the transmission rod and the guide rod are arranged in a mode of being mutually parallel; by virtue of the driving device, the screw rod is driven to rotate on its axis; one end of the transmission rod is connected to the pushing head and the other end of the transmission rod is connected to the transmission sliding block; the transmission sliding block can be moved in a length direction of the guide rod; a clutch nut and a clutch cam, which abut against each other, are arranged on the transmission sliding block; by virtue of the clutch control mechanism, the clutch cam is driven to rotate, and the clutch nut and the screw rod can be controlled to get meshed or separated through rotation of the clutch cam, namely power is transmitted to the clutch nut through rotation of the screw rod, and the pushing head is directly driven to advance by virtue of the clutch nut; therefore, the injection pump transmission device is simple in force transmission route and is high in transmission anti-interference performance; and moreover, the injection pump transmission device is also simple in structure and is conducive to structure miniaturization.
Description
technical field [0001] The invention relates to a technical solution in the field of syringe pumps, in particular to a syringe pump transmission device and a syringe pump used therein. Background technique [0002] Syringe pumps are commonly used in hospitals to infuse human veins with precision. It can adjust the infusion of medicine at a fixed time, quantity and speed according to the patient's condition. This feature and its advantages of convenient operation allow patients to get better treatment. It also effectively reduces the workload of medical staff. [0003] Syringe pumps can generally be divided into manual control, electric control, and flashlight hybrid control according to their driving working principle. The electronically controlled syringe pump is labor-saving and easy to operate, but it is relatively poor in response speed, driving speed and flexibility. Compared with the pure electric control, the structure of the manually driven syringe pump is more com...
