Aspirator (medical Device)
A medical aspirator is a suction machine used to remove mucus, blood, and other bodily fluids from a patient. They can be used during surgical procedures but an operating theater is generally equipped with a central system of vacuum tubes. Most aspirators are therefore portable, for use in ambulances and nursing homes, and can run on AC/DC or battery power. They consist of a vacuum pump, a vacuum regulator and gauge, a collection canister, and sometimes a bacterial filter. Plastic tubing is used to continuously draw fluid into the collection canister. In the past manually operated aspirators were used such as ''Potain's aspirator''.p. 97, Minor surgery, Henry R. Wharton, i''System of surgery'' vol. II, Frederic S. Dennis and John S. Billings, eds., Philadelphia: Lea Brothers & Co., 1895. See also * Suction (medicine) In medicine, devices are sometimes necessary to create suction. Suction may be used to clear the airway of blood, saliva, vomit, or other secretions so tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aspirator (pump)
A vacuum ejector, or simply ejector is a type of vacuum pump, which produces vacuum by means of the Venturi effect. In an ejector, a working fluid (liquid or gaseous) flows through a jet nozzle into a tube that first narrows and then expands in cross-sectional area. The fluid leaving the jet is flowing at a high velocity which due to Bernoulli's principle results in it having low pressure, thus generating a vacuum. The outer tube then narrows into a mixing section where the high velocity working fluid mixes with the fluid that is drawn in by the vacuum, imparting enough velocity for it to be ejected, the tube then typically expands in order to decrease the velocity of the ejected stream, allowing the pressure to smoothly increase to the external pressure. The strength of the vacuum produced depends on the velocity and shape of the fluid jet and the shape of the constriction and mixing sections, but if a liquid is used as the working fluid the strength of the vacuum produced is l ...
