Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a novel handheld negative pressure sputum suction device for emergency use. Background technique [0002] In the emergency department, we often encounter critically ill patients who need to suck sputum immediately to clear the airway. The sputum suction devices commonly used in clinical practice are relatively bulky, poor in portability, and inconvenient to operate, which wastes precious rescue time. Therefore, it is necessary to design a simple and portable sputum suction device that can be operated with one hand to facilitate the use of medical staff when rescuing critically ill patients. For this reason, we propose a new type of handheld negative pressure sputum suction device for emergency use. Contents of the invention [0003] The purpose of the present invention is to provide a novel emergency hand-held negative pressure sputum aspirator to solve the problems rai...
