Electric suction device suction is utilized the principle of negative pressure effect.
The electric suction device mainly relies on the pressure difference of air. When the electric suction device is turned on by the power supply, the internal motor will drive the eccentric wheel to rotate rapidly, and the air inside the liquid storage bottle and the safety bottle will be sucked out from the suction hole. Repeated rotation of the eccentric wheel will slowly turn the pressure inside the two bottles into negative pressure, and then suck out the sticky phlegm in the trachea.
The principle of the electric suction device is very simple, that is, through a certain method to create a negative pressure state of the suction head, so that the atmospheric pressure will be outside the suction head of the material to the suction head extrusion, so as to complete the "attraction" effect. In the use of electric attractor, the user needs to pay attention to adjust the negative pressure must be carefully checked before, attractor pipeline is normal and smooth.
Electric suction technology development
1, centralized
With the improvement of people's living standards, health requirements are also increasing, the use of suction device demand has also increased significantly, therefore, large hospitals are generally used to centralize the centralized control of the center of the negative pressure to solve this problem. Generally take the negative pressure interface on the equipment belt, convenient, safe, easy to deploy in large quantities, while easy to manage, low cost.
2, intelligent
In the electric suction, make full use of the advantages of intelligence, emerged a number of intelligent microcontroller-controlled medical suction equipment. This kind of electric suction device through the control of the program within the microcontroller, to complete a series of flushing, sucking up the function, convenient for health care workers, improve the efficiency and reduce the error.
