The suction pumps are designed for small surgical aspirations.
They also can be used for treating tracheotomised patients at home, and for pharyngeal use. [*A tracheotomy is a surgical procedure that opens up the windpipe (trachea)].
It is used to aspirate sputum and suction apparatus for patients in hospital and household [*Sputum is mucus that is coughed up from the lower airways].
• Suction is the flow of a fluid into a partial vacuum, or region of low pressure. The pressure gradient between this region and the ambient pressure will propel matter toward the low pressure area. Suction is popularly thought of as an attractive effect, which is incorrect since vacuums do not innately attract matter.
• Pumps typically have an inlet where the fluid enters the pump and an outlet where the fluid comes out. The inlet location is said to be at the suction side of the pump.
• The outlet location is said to be at the discharge side of the pump. Operation of the pump creates suction (a lower pressure) at the suction side so that fluid can enter the pump through the inlet.
• Pump operation also causes higher pressure at the discharge side by forcing the fluid out at the outlet. There may be pressure sensing devices at the pump's suction and/or discharge sides which control the operation of the pump.
The applications of surgical pump are as follows:
Suction pumps are used during and after surgery to remove surgical fluids, tissues (including bones), gases or bodily fluids of the patient.
