AI Technical Summary

Technical Problem

Existing anti-clogging respiratory airway suction devices still cannot completely prevent blockage when faced with thick and large amounts of lumpy sputum, affecting the suctioning process and even endangering the patient's life.

Method used

A suction device comprising an airway tube, an adjustment block, a probe, a connecting tube, a cleaning rod, and a motor was designed. The device uses an adjustment mechanism and an electric push rod to drive gear meshing, thereby adjusting the angle of the probe and sliding the cleaning rod to clear sputum blockages from the airway and ensure a smooth suctioning process.

Benefits of technology

It effectively prevents airway blockage, ensures a smooth suctioning process, reduces the risk of blockage, and improves the safety and efficiency of suctioning.
