Description

A special phlegm suction device for pediatrics

Technical Field

The invention relates to the technical field of sputum suction equipment, in particular to a special sputum suction device for pediatrics.

Background

When the internal medicine patient is recovering in the treatment, because the health secretion is more, need carry out the discharge through the sputum extracorporeally.

The traditional sputum suction device usually adopts negative pressure to suck sputum, the principle of the negative pressure sputum suction is that air in the sputum aspirator is discharged through pressing a pinch air bag, negative pressure is formed in the sputum aspirator at the moment, and sputum enters the sputum aspirator along a sputum suction pipe, so that the sputum suction device has the advantages of simplicity and easiness in operation.

However, this sputum aspirator has the following disadvantages: firstly, when pressing the gasbag, the gasbag deformation flattens, and the sputum can not arrange into the sputum aspirator this moment, waits to loosen the gasbag, and the gasbag recovers the back, and the sputum just gets into the sputum aspirator under the negative pressure effect, therefore the gasbag is according to the in-process of pine, can only carry out once and inhale the phlegm, and the total amount of inhaling the phlegm is unchangeable, and the number of times of inhaling the phlegm increases, and consuming time extension, inefficiency, and the sputum suction tube is detained and is prolonged more in patient's larynx cavity time moreover, can increase patient's pain. Secondly, medical staff can collect and analyze the sputum after absorbing the sputum to judge the health condition of the patient, but impurities exist in the sputum, for example, the patient can have undigested food due to deep dry cough and retching of the sputum absorbing pipe, and the sputum can have the undigested food, so that the sputum needs to be filtered after absorbing the sputum, and the traditional sputum absorbing device does not have the filtering function.
