Multi channel independent control split type injection pumps are widely used in fields such as medicine, laboratory, and life sciences, especially in scenarios that require precise control of drug or solution injection. It can control multiple channels simultaneously, achieving precise control of multiple liquids through independent parameters such as injection rate, injection volume, and time.
The following is a guide for using a multi-channel independent control split injection pump:
1、 Equipment Overview
A multi-channel independent control split type injection pump usually consists of two parts:
Main control unit: responsible for overall system control, including display, setting operating parameters, communication interfaces, etc.
Pump body unit: Each pump body is responsible for an injection channel and has an independent drive system that can be set and controlled separately.
2、 Preparation before operation
Equipment inspection:
Check all components of the infusion pump to ensure that the pump body, pipes, connectors, etc. are not damaged.
Ensure that interfaces such as power, control, and data cables are intact and free from breakage or wear.
Install syringe:
Install appropriate models and specifications of syringes as needed, ensuring that the interface between the syringe and the infusion pump matches.
Fix the syringe correctly on the pump body, ensuring its stable installation and avoiding detachment during operation.
Connecting pipeline:
Connect the output end of the syringe to the tubing required for the experiment, and the tubing should be free of bends or blockages to ensure smooth liquid flow.
When connecting, ensure that all connection points are securely fastened to avoid leakage.
Liquid preparation:
Prepare the injection liquid according to the experimental requirements, which should be clean and free of impurities.
If necessary, check the viscosity of the liquid to see if it is suitable for the current operation of the infusion pump.
Power check:
Ensure that the power connection is normal, and before starting the device, make sure that both the host power supply and the pump body power supply are connected.
3、 Operation steps
Start device:
Turn on the main power of the device and start the control panel.
After the system is started, it usually displays the main interface and shows the working status of each channel.
Set injection parameters:
Select the channels that need to be set (each channel can be set independently).
Set the injection rate (e.g. injection volume per minute), injection time, or total injection volume for each channel.
Adjustable parameters typically include: flow rate (ml/min), total amount (ml), pressure, pulse mode (continuous/quantitative injection), etc.
During the setup process, the parameters of each channel can be adjusted according to specific needs to achieve different injection schemes.
Start the injection process:
After setting up, press the start button and the infusion pump will start working.
The device will automatically operate according to the preset injection rate and injection volume. If the device supports display, the screen will display the injection status of each channel in real-time.
Real time monitoring:
During the injection process, monitor the parameter changes displayed on the pump body to ensure that no abnormalities occur (such as bubbles, blockages, high pressure, etc.).
If the device supports it, alarm thresholds can be set through the alarm system on the device to prevent liquid injection errors from occurring.
注射完成：
After the injection is completed, the device will automatically stop running and display the total amount of injection completed.
Turn off the device, remove the syringe and tubing, and perform necessary cleaning and disinfection.
4、 Precautions
Compatibility between syringe and pump body:
Ensure that the syringes used meet the equipment specifications to avoid equipment malfunctions caused by mismatches.
Liquid selection:
The injected liquid must be compatible with the selected syringe, tubing, and pump body materials to avoid corrosion or contamination.
When using viscous liquids, attention should be paid to the maximum output pressure and maximum flow rate of the pump body to avoid excessive burden on the pump body.
Injection speed setting:
When setting the injection speed, be careful not to exceed the maximum flow rate limit of the injection pump, otherwise it may cause equipment damage or liquid leakage.
If encountering viscous liquids or macromolecular solutions, it is recommended to reduce the injection rate appropriately.
Liquid blockage inspection:
Regularly check the tubing and syringes to ensure there are no bubbles or blockages. When there is a blockage, the operation should be stopped immediately, the pipeline should be checked or the syringe should be replaced.
Battery and power management:
If the device is equipped with a backup battery, the battery level should be checked regularly to avoid sudden power outages caused by insufficient battery power.
Maintain the stability of the power supply to avoid voltage instability affecting equipment operation.
Environment and Temperature and Humidity:
The equipment should be used in a dry, clean, and non corrosive gas environment to avoid extreme environments such as high temperature and high humidity that can affect equipment performance.
5、 Maintenance and upkeep of equipment
Cleaning and maintenance:
Regularly clean the equipment, especially the parts in contact with the syringe and pump body. Non polluting and non corrosive cleaning solutions can be used for cleaning.
Regularly inspect the pipeline for any residue or dirt to avoid blockages.
Regular calibration:
To ensure equipment accuracy, it is recommended to perform regular calibration. Standard solutions with known flow rates and volumes can be used for testing to ensure the accuracy of the equipment.
Check the battery and power supply:
Regularly check the battery life of the equipment, and if the battery level drops significantly, replace the battery in a timely manner.
Ensure the cleanliness of the power interface and battery interface to avoid affecting device stability.
6、 Common faults and solutions
Unable to start:
Check the power connection and ensure that the power cord is not loose or damaged.
If there is a battery, check if the battery is fully charged.
Unstable operation of infusion pump:
Check for any air bubbles or liquid blockages to ensure the pipeline is unobstructed.
Confirm that the set flow rate matches the liquid viscosity and adjust the appropriate injection rate.
Display exception:
If the control panel displays abnormalities or is unresponsive, try restarting the device or checking if the control system is malfunctioning.
summary
The multi-channel independent control split type injection pump is a highly flexible and precise device that has a wide range of applications in multiple fields. The correct usage method can ensure the stable operation of the equipment and ensure the accuracy and safety of the experiment. During operation, it is essential to pay attention to the parameter settings and real-time monitoring of the equipment, and promptly handle any possible abnormal situations.
