Abstract：Objective To develop a new generation of stable and safe sputum suction device to replace nursing staff in sputum suction
operation, aiming at the core operation of the delivery tube and the withdrawal tube in the artificial airway of the previous sputum
suction device. Methods Based on the research and development of the previous generation of simulated sputum suction robot,
the push-pull, speed, time and other relevant parameters of the sputum delivery and desorption tube had been obtained, by using
magnetic coupling drive and roller transportation, non-contact power transmission was achieved to reduce the holdup and ensure the
stability of the sputum suction tube delivery and withdrawal. Through the feasibility training on the sputum suction practice model
of artificial airway, the effectiveness and safety of the sputum suction device were ensured. Results Feasibility training showed that
in 20 effectiveness simulation experiments, about 5-9 mL of simulated sputum was successfully extracted in 17 experiments, with an
average extraction of about 7.5 mL. In 10 safety simulation experiments, there was no significant difference in the thrust, tension and
rotation force between sputum suction device and manual sputum suction device in the process of delivery and withdrawal (P＞0.05).
The data of sputum suction device was more stable. Conclusion The sputum suction device can transmit and exit the sputum suction
tube stably and safely, which can effectively complete the sputum suction operation. It is easy to disassemble, clean and disinfect,
which can effectively reduce the work burden of medical staff.
