AI Technical Summary
During the emergency rescue process, the existing drainage bag is prone to cause exudate reflux due to collision, squeezing or position change, which affects the rescue effect.
A backflow prevention piping system including left-leaning and right-leaning pipes was designed, equipped with flow-limiting beads and limiting rods. Gravity and an extrusion plate structure were used to prevent the backflow of seepage. The rotation of the flow-limiting beads and the fixation of the limiting rods ensured that the pipeline flow was reduced or closed to prevent backflow.
It effectively prevents the drainage bag from backflowing when it is shaken, laid flat or inverted, and seals the pipeline when squeezed, ensuring the stability and anti-reflux effect of the drainage bag.
