Multi channel infusion pump

Structure and Working Principle

• Structure:Multi channel infusion pumpGenerally includes a housing, at least one main control device, and at least two injection channels. Each injection channel also includes a support device for supporting the syringe, a pump device for driving the syringe for drug injection, and a detection device.

• Working principle: Its core component is a piston pump head driven by an electric motor. There are multiple independent channels inside the pump head, each channel has an independent piston and its related control components, such as sensors, valves, pipelines, etc. By driving the piston with an electric motor, fluid is transported, and the control components of each channel work together to achieve flow control between different channels.

• Main Features

• Multi channel independent control: Each channel can independently set parameters such as flow rate, dosage, and delivery mode, which can simultaneously deliver multiple drugs or liquids to meet complex experimental or therapeutic needs and reduce the burden on operators.

• High precision and stability: High precision stepper motors or servo systems are usually used, with flow rate accuracy up to ≤± 0.5%, and some high models up to ± 0.1%. At the same time, it has built-in pressure sensors and blockage alarm functions to monitor the infusion status in real time.

• Intelligent and user-friendly design: equipped with a large LCD screen, supporting Chinese/English interfaces, and intuitive operation. It also supports functions such as power-off memory, automatic calibration, data storage, and remote monitoring.

• Compatibility and Scalability: Compatible with multiple specifications of syringes, such as 10 μ L-60mL, suitable for different scenarios. Some models support expansion to 8-16 channels to meet high traffic requirements.

• Multi channel parallel transmission: It can simultaneously control the liquid delivery of 4, 6, 8 channels or even more channels, significantly improving flux and work efficiency.

• Technical parameters

• Flow range: Injection accuracy can reach the microliter level, with a common range of nL – mL.

• Number of channels: Generally, there are 4, 6, 8 channels, etc., and some models can be expanded to 8-16 channels.

• Accuracy: The flow velocity accuracy is usually ≤± 0.5%, and some high models can reach ± 0.1%.

• Application scenarios

• Medical field: In drug development, multiple drugs can be administered simultaneously in cell experiments or animal models to observe synergistic effects or toxic reactions. In clinical treatment, it can be used for intensive care, achieving multi drug combination infusion, or long-term nutritional support.

• In the field of biotechnology, precise control of the injection amount of culture medium, growth factors, and buffer solution can be achieved in cell culture to ensure consistency in the cell growth environment. In microfluidic chips, nanoscale fluid manipulation can be achieved for disease diagnosis or drug screening.

• In the field of chemical analysis: In chromatographic analysis, the injection amount of the sample can be precisely controlled to improve the repeatability of the analysis. In the study of reaction kinetics, multiple reagents can be added simultaneously to investigate the relationship between reaction rate and product generation.

• In the fields of industry and scientific research, it can be used for liquid distribution of microbial strains in synthetic biology, parallel liquid injection for nanomaterial synthesis reactions, and pretreatment for high-throughput chemical analysis of food and environmental samples.
