Suction is the day-to-day term for the movement of gases or liquids along a pressure gradient with the implication that the movement occurs because the lower pressure pulls the gas or liquid. However, the forces acting in this case do not originate from just the lower pressure side, but also from the side of the higher pressure, as a reaction ...
In many hospitals and other health facilities, suction is typically provided by suction regulators, connected to a central medical vacuum supply by way of a pipeline system. The plastic, rigid Yankauer suction tip is one type of tip that may be attached to a suction device. Another is the plastic, nonrigid French or whistle tip catheter.
In non-emergency situations, intermittent suction is often applied giving the benefits of suction without the untoward effects of damage to the stomach lining. [4] Suction drainage is also used for patients who have undergone a pneumonectomy in order to prevent anesthesia-related vomiting and possible aspiration of any stomach contents. Such ...
Negative-pressure wound therapy (NPWT), also known as a vacuum assisted closure (VAC), is a therapeutic technique using a suction pump, tubing, and a dressing to remove excess exudate and promote healing in acute or chronic wounds and second- and third-degree burns. The therapy involves the controlled application of sub-atmospheric pressure to ...
Suction is the vertical distance between the fluid to be pumped and the centre of the pump, while lift is the vertical distance between the pump and the delivery point. [4] The depth from which a hand pump will suck is limited by atmospheric pressure to an operating depth of less than 7 meters. [ 5 ]
In a less obtrusive way, a trocar button can be used in place of a suture. It is attached to a suction hose, usually attached to a water aspirator, but an electric aspirator can also be used. The process of removing gas, fluids, and semi-solids from the body cavities and hollow organs using the trocar is known as aspiration.
A suction cup, also known as a sucker, is a device or object that uses the negative fluid pressure of air or water to adhere to nonporous surfaces, creating a partial vacuum. [ 1 ] Suction cups occur in nature on the bodies of some animals such as octopuses and squid , and have been reproduced artificially for numerous purposes.
A suction excavator, or vacuum excavator, is a construction vehicle that removes heavy debris or other materials from a hole on land using vacuuming. Suction excavators are meant to be less destructive than regular excavators . [ 1 ]
