The core of the injection pump - stepper motor

The times are developing, and now automation and intelligence are the trend of development. As a medical field closely related to everyone, it is also constantly integrating with other fields. It is also developing towards automation and intelligence, and a representative product is the injection pump. Nowadays, in the developed West, injection pumps have been widely used, but the injection pump has not yet been included in medical insurance, and its use price is high. Only a small number of people can experience its practicality and effectiveness. The popularization of injection pumps in the world is an inevitable trend, and China will be a huge market in the short term.

The injection pump is composed of a stepper motor and its driver, a screw rod, and a bracket, etc. It has a reciprocating screw rod, nut, and is also known as a screw pump. The nut is connected to the piston of the syringe, which holds the liquid medicine, achieving high-precision, stable and pulsatile liquid transmission.

The clinical application of injection pumps: When the drugs used in clinical practice must be injected through intravenous routes, and the dosage must be very accurate, the total amount must be small, and the delivery rate must be slow or constant for a long time, injection pumps should be used to achieve this goal. This requires a controllable speed stepper motor, which requires high accuracy, good dynamic performance, no obvious oscillation, excellent start stop and reverse response, and a wide speed range.

Wanzhida has over 50 types of stepper motors, which meet the above requirements in terms of performance and parameters, and has its own advantages compared to other motors on the market. If you have special requirements, Wanzhida also provides parameter customization services.
