Topics • Principles of operation • Diagrams • Applications • Types of suction pumps • Safety • Operation • Preventive maintenance • Common failure modes • Basic troubleshooting
Principles of Operation • Suction generated using a pump • Pump powered by electrical motor or foot pedal • Pump moves piston up and down • Piston attached to air tight diaphragm • Pulls air in from collection container through one-way valve to reduce pressure • Reduced pressure draws fluid from patient via tubing • Fluid remains in bottle until disposal • Valve prevents fluid from passing into motor • Motor speed determines suction strength

Applications • Used to remove fluid from body cavities • Removal of: • Surgical fluids in the operative field • Mucosal secretions • Used in patients with compromised swallowing or coughing
Safety • ALWAYS use PPE when working with suction pumps • Pumps come in direct contact with bodily fluids • Wash hands immediately after removing gloves • Never fill the collection container more than 75% full • Liquid will enter pump • Before using, read the owner's manual
Operation • Position the unit close to patient • Plug into AC power (do not use extension cords) • Attach first suction tubing from pump suction control to collection bottle outlet • Attach second suction tubing to collection bottle inlet
Operation • Check all components and connections for tight fit • Turn suction pump on (on/off electrical switch) • Crimp tubing coming from the collection bottle inlet • In order to test full range of suction • Adjust suction to desired level while observing vacuum gauge • Initiate suction procedure
Preventive Maintenance • Daily • Clean filters • Clean air vents • Disinfect jars, tubing, other components that come into contact w/ patient fluids between each use in solution of water, detergent, and disinfectant • Change bacteria filter if wet or discolored • Check collection bottle/jar for cracks, chips, and other damage • Make sure there is a sufficient supply of bacterial filters • Check that float valve moves freely • 1-3 months • Clean or replace air intake filter • Clean brushes on motors as necessary • Inspect power cord and plug • Ensure vacuum works over full range of suction pressures if there is a control/knob • Verify that overflow valve (float valve) works properly when container is filled with water • Grounding resistance between chassis and ground pin should not exceed 0.5 ohms
Common Failures • Most common: Clogs, Leaks, Motor Failure • Leaks: • Tube leak • Jar/lid leak (bad O-ring, possibly) • Tube blockage or kink • Missing/damaged parts: • Bad motor • Bad power supply • No collection bottle • No filter • Clogged bacterial filter • Float valve closes air pathway with full collection jar • Insufficient pressure/suction • Ventilation grill obstructed • Suction control knob is set to a low setting • Diaphragm needs cleaning or replacing • Brushes need cleaning • Motor needs lubrication
