Description

technical field

[0001] The invention relates to the field of medical equipment, in particular to an emergency sputum suction device for respiratory medicine. Background technique

[0002] Respiratory medicine, medical staff checks the patient for phlegm in the throat, and urgently clears the phlegm for the patient, otherwise the patient has difficulty breathing, which may endanger the patient's life in severe cases. Usually, severe patients or comatose patients have phlegm and cannot cough it out on their own , At this time, it is necessary to use a sputum suction device to help the patient suck out the sputum.

[0003] Usually, the sputum suction device adopts the principle of negative pressure. One is to use an air pump type to suck out the sputum in the throat through a catheter; the other is to use a piston type to suck out the sputum in the throat by pulling the piston rod. However, the air suction pump type has a large footprint, is not easy to carry, is inconvenient ...
