AI Technical Summary
Technical Problem
Existing negative pressure drainage bags are unstable when opened, easily popping open automatically. Positional deviations lead to poor drainage, sharp corners are easily punctured, and insufficient opening results in insufficient negative pressure and unsatisfactory drainage effect.
Method used
The design incorporates a toothed structure with an inclined upper and lower plate, combined with movable wings and arc-shaped baffles. Through elastic components, it achieves stable locking and full expansion, providing sufficient negative pressure to prevent misalignment and puncture.
Benefits of technology
It achieves stable expansion of the drainage bag, enhances negative pressure, prevents misalignment and puncture, improves drainage efficiency, and extends service life.
