Sputum aspirator is a class of medical devices

Summary: Suction device is a kind of medical equipment, generally manual sputum suction device belongs to the first class medical equipment, electric sputum suction device belongs to the second class medical equipment. The work of the sputum aspirator mainly utilizes the principle of negative pressure, whether it is a manual sputum aspirator or electric sputum aspirator, is through the creation of a negative pressure environment to suck out the sputum in the patient's body, as for the negative pressure how much, according to the patient's condition and sputum viscosity adjustment, generally in the 40.0-53.3KPa can be. Here is a look at the principle of sputum aspirator. First, the sputum suction device is a few categories of medical equipment

Sputum suction device is a kind of medical equipment, general medical sputum suction device is more powerful, household sputum suction device is more inclined to health care equipment, according to the state regulations, the medical equipment is divided into three categories, so the sputum suction device belongs to a few categories of medical equipment it?

The sputum extractor as a medical device is divided into two types: manual sputum extractor and electric sputum extractor, of which the manual sputum extractor belongs to Class I, managed by Class I medical devices; the electric sputum extractor belongs to Class II, managed by Class II medical devices, classified under the classification of No.6854 or No.6866.

What is the principle of the sputum extractor?

Sputum extractor is commonly used in oropharyngeal suction or tracheal intubation patient tracheal suction, which is the most important part of the sputum extractor. Tracheal suction for intubated patients to remove secretions, blood, vomit and other substances that cause respiratory obstruction, so that the respiratory tract remains open, but many people are not too clear about the working principle of the sputum aspirator, so what is the principle of the sputum aspirator?

The principle of the sputum aspirator mainly utilizes the principle of negative pressure.

1, the structure principle of manual sputum aspirator

General manual sputum aspirator consists of pump, piston, handle, sputum storage chamber, sputum suction tube and sputum discharge tube connector, by pressing the handle, the sputum storage chamber and the patient's mouth or throat will form a negative pressure, under the action of the pressure difference, the sputum will be through the sputum suction tube from the patient's oral cavity into the sputum storage chamber.

2, the principle of electric sputum aspirator

Electric sputum aspirator consists of power supply, motor, eccentric wheel, storage bottle, safety bottle, sputum suction tube, sputum tube and other structures, when the power supply is turned on, the motor of the sputum aspirator will drive the eccentric wheel to rotate, and the air inside the storage bottle and the safety bottle will be sucked in from the suction holes and discharged by the discharge holes, and then rotate again and again, and the air pressure inside the two bottles will become negative, so that sputum will be sucked out. The air pressure inside the two bottles will become negative pressure, and thus the sputum will be sucked out.

Three, sputum aspirator negative pressure is how much

Sputum aspirator generally need to achieve a certain negative pressure to be able to suck out the sputum, under normal circumstances, the use of sputum aspirator needs to be adjusted according to the patient's condition and sputum viscosity negative pressure, suction negative pressure pressure adjustment for the attraction of 40.0-53.3KPa can be.
