Sputum suction device for emergency department
By introducing a C-shaped guiding silicone shell and clamping guide into the suction device, the problems of operational dependence and poor tubing guidance during deep suctioning of elderly patients have been solved, enabling precise suctioning that can be controlled by one hand and improving the efficiency and safety of airway management in the emergency department.

AI Technical Summary
Existing suction devices are inefficient and require assistance to operate when performing deep suction on elderly patients. They also have poor tubing guidance and are inefficient, increasing labor costs and operational errors. Furthermore, they are not ideal for emergency care.
A suction device comprising a C-shaped guiding silicone shell and an integrated clamping guide has been designed. The C-shaped guiding silicone shell provides axial support and universal ball bearings to reduce friction, while the clamping guide provides radial clamping. Combined with an adjustable wearable part, it enables one-handed operation.
It enables precise and smooth insertion of suction catheters, improves the success rate of first-time intubation and operational safety, reduces human resource costs, shortens operation time, and reduces the risk of mucosal damage and cross-infection.
