Medical infusion pumps and injection pumps not only improve efficiency, flexibility, and reliability in clinical drug administration operations, but also reduce the workload of nursing staff and minimize disputes between medical staff and patients. One of the core components of these devices is the coreless motor, which plays a crucial role in driving the operation of the infusion pump.
The scheme of a medical injection pump typically consists of a motor and its driver, a lead screw, and a support structure. This design includes a reciprocating lead screw and nut, which is why it is sometimes referred to as a lead screw pump. The nut is connected to the piston of the syringe, which is filled with medication. In this way, the injection pump can achieve high-precision and pulsation-free liquid transfer.
During operation, the motor drives the lead screw to convert rotational motion into linear motion, thereby pushing the piston of the syringe for injection and infusion. This process requires the motor to have precise control capabilities and high stability. Therefore, the quality of the motor directly affects the performance of the infusion pump and the accuracy of the infusion.
In addition, the infusion pump is equipped with various sensors, such as infrared drop sensors, pressure sensors, and ultrasonic bubble sensors, for detecting liquid flow rate and volume, blockage pressure, and leakage and bubbles. The data from these sensors are used in the microcomputer system to ensure precise control and safety of the infusion process.
Overall, the motor plays a central role in medical infusion pumps and injection pumps. It not only needs to provide stable power output but also needs to work precisely with other components of the pump to ensure that medication is delivered to the patient's body at the precise rate and dosage. Therefore, the performance and reliability of the motor are crucial to the safety and effectiveness of the entire infusion system.
