I. Core Design Principles
The core goal of a continuous-flow syringe pump is to achieve "seamless fluid replacement." Its design revolves around this goal:

Dual/Multi-Pump Coordinated System: The device typically consists of two or more independent injection units (pump bodies). A primary pump provides normal fluid supply, while a backup pump is pre-loaded with fluid and on standby.
Intelligent Switching Mechanism: Sensors monitor the primary pump's fluid level, operating progress, or pipeline pressure in real time. When the primary pump is nearing depletion (e.g., the remaining liquid volume reaches a preset threshold), the system automatically triggers a switchover sequence.
Pressure/Flow Compensation Technology: During the switchover process, an algorithm adjusts the startup speed and pressure of the backup pump to ensure stable flow and pressure within the pipeline at the moment of switching, avoiding flow fluctuations or interruptions caused by pump changes.
Closed-Loop Feedback Control: Combining a high-precision flow sensor and a microprocessor, the system compares the actual flow rate with the set value in real time, dynamically adjusting the pump's operating parameters to ensure long-term fluid supply accuracy.

II. Key Technical Features
1. Core Advantages of Uninterrupted Fluid Supply
Zero-Interruption Fluid Exchange: This completely eliminates the need to shut down traditional pumps to change syringes or tubing, making it particularly suitable for scenarios requiring long-term continuous fluid supply.
Smooth Switching: By pre-priming a backup pump and using a pressure-matching algorithm, flow rate fluctuations during switching are guaranteed to be ≤5% (≤2% for high-end models), minimizing disruption to patient hemodynamics or laboratory data.

2. Intelligent Collaborative Control System
Real-time linkage between liquid supply speed and atomization power: Automatically adjusts ultrasonic vibration intensity to ensure stable droplet concentration when liquid supply changes.
Status Monitoring and Alarms: Real-time monitoring of parameters such as remaining liquid volume, atomization chamber liquid level, droplet size, and pipeline patency. Audible and visual alarms are triggered in the event of anomalies (e.g., low liquid level, blockage, or decreased atomization efficiency).
