What is the difference between an aspirator and a suction device

So what's the difference between a medical aspirator and a suction device? Which one is better?

Medical sputum aspirator and suction device are both used to suck foreign bodies in the body, and both are very good to use. Medical sputum aspirator is used for patients who have difficulty in spontaneous sputum production due to disease, coma, surgery, etc., and can be used for clinical suction of pus, blood and other liquids. It is the standing equipment for emergency room, operating room, ward monitoring and home care. Medical sputum aspirator to keep the respiratory tract open, prevent aspiration pneumonia,

pulmonary asphyxia, asphyxia and other complications.

A suction device is used to suction out bleeding, exudate, pus, and the contents of thoracic organs during surgery to make the surgery clear and reduce the chance of contamination. Surgery in the removal of blood or fluid accumulation, hold the broken ends of ruptured blood vessels, clinical emergency sputum suction, gynecological surgery abortion, etc., are inseparable from the suction device.

Medical sputum suction device connected to the power supply of the electric suction device, sputum suction device suction motor drives the eccentric wheel, from the suction holes to suck out the reservoir bottle and the safety bottle of air and by the exhaust holes discharge, so that week after week rotation, so that the two bottles to produce a negative pressure will be sucked out of the sputum.

The principle of the 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 to squeeze, so as to complete the "attraction" effect. No matter what type of attractor, the principle is the same. Thank you for coming!
