During rescue operations in the aftermath of earthquakes and other natural disasters, emergency personnel often need to hold IV bottles (or bags) aloft while providing treatment to the injured, constantly monitoring the status of the infusion equipment. In harsh environments, this practice is exceptionally challenging, posing significant inconveniences to the rescue efforts.This is a portable automatic infusion pump that operates without the need for electricity or gravitational assistance, specifically designed for emergency relief efforts in disaster areas. It functions autonomously in environments lacking power sources and where elevating the infusion set is impractical, delivering 300ml of medication to injured individuals. The core components of this device include a medication vial, piston, compression spring, casing, and valve. Its mechanism relies on a compressed spring to drive the piston, thereby infusing the medication into the patient. First responders can finely adjust the fluid flow rate by turning the valve, allowing precision control tailored to each patient's requirements, accurate down to drops per minute.This device requires no external power supply and does not rely on gravity, enabling immediate deployment and operation in extreme environments where there is a total power outage or悬挂 conditions are unfeasible. This feature guarantees that in disaster scenarios such as earthquakes or floods, which often disrupt infrastructure, the infusion pump can swiftly be put into action without environmental constraints. Designed with a focus on streamlining operational procedures, medical responders can precisely调节 the fluid flow rate simply by turning the valve, with adjustments as fine as drops per minute, significantly reducing the complexity of operation and training costs. Even in the tense atmosphere of a rescue mission, non-professionals can quickly learn to use the device with brief instructions, enhancing the flexibility and efficiency of emergency responses.Independent of power supply, it is suitable for various disaster scenarios, ensuring therapy continuation uninterrupted by power failures, thereby enhancing safety during usage.
