AI Technical Summary
Existing manual suction devices require at least two people to operate, which is inconvenient and results in intermittent negative pressure, affecting the suction effect.
A portable sputum suction device was designed, which adopts an electric suction device and an anti-fall ring structure, allowing single-person operation. It generates continuous negative pressure through an electric telescopic rod, and combined with a filter screen, it prevents sputum from entering the air supply tube.
It achieves the convenience of single-person operation and the continuity of negative pressure, improves the efficiency and effectiveness of sputum suction, and reduces the risk of damage from external forces.
