Suction

What is a suction?

Recently, one of the most important medical equipment that should be used in any departments of a hospital is suction.

Central Suction

In most modern times, The main sources of a vacuum should usually be located in hospitals (the basement of the building). It is a pump and a reservoir.
Vacuum should be available from wall outlets located throughout of each departments of the building.
The pump creates a vacuum by emptying a reservoir tank that delivers through connecting pipes to wall outlets in hospital departments (patient care areas).
Regularly the vacuum pressure restores by engaging a switch when it falls to a predetermined level.
When it builds back up, the switch disengages and no further vacuum is created.

The rate of flow

The flow rate is determined by three factors:

Portable suction

Can be used to produce vacuum, particularly for hospital areas not served by the wall system (central suction) or those that are not equipped by central suction system.
Generally, the structure and function of all suctions are the same and they only differ in terms of the system used in vacuum pump.

The main parts of portable suction are:

Motor
Vacuum Gauge
Vacuum Regulator
Vacuum Pump
Connective Tubes
Suction Jar(glass)
Filter

System Component

Motor: Moving vacuum pump which is connected to it. (the oily type has high motor power)

Vacuum Gauge: Showing vacuum power based on two units of measuring the bar and mmHg pressure.

Maximum pressure that could be generated is 1000 mmHg.

Vacuum Regulator: Adjusting the amount of vacuum which is created. (implemented on the body of suction)

Vacuum Pump: creating vacuum inside the pump itself. (this is the most important part of the suction)

It has three models:

Piston
Diaphragm
Oil

System Component…

Connective Tubes: The tubes are connected to two main openings of the pump, one for suction (vacuum) and the other for blow (air) and they are divided into other sub-branches.

Usually, the suction head is connected to disposable sterile tubes.

In operation rooms, based on a surgical place and the surgeons option, different suction tips could be used.

Suction Jar: It has different capacities and two openings, one for connection to a vacuum pump and the other for connection to the suction hose.

For preventing the liquid from entering into the connecting tubes and the pump. it has a control ball(valve) that works as the liquid inside the glass goes up.
