Common failure modes

3. 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

8. 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

9. 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

10. 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

11. 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

12. 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

13. 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
