Procedure for Cleaning Twin-O-Vac Suction System

Introduction

The Twin-O-Vac suction system may require cleaning. This may be due to incorrect, or lack of, filter usage, or by over-filling. This document will explain the recommended procedures for cleaning.

Please note: Suction hose and filters are single use consumables and should be discarded after such use. Failure to replace partially or fully blocked filters will cause the system to operate inefficiently!

Steps: –

1. Ensure that you are in a clean and traffic free environment.
2. Fit surgical type gloves or equivalent.
3. With filters removed, prepare the unit for normal operation.
4. Ensure the Twin-O-Vac is turned OFF before turning the gas cylinder ON.
5. Prepare approximately 300 mL of cold sterilisation solution, such as ‘Hibitane’ etc.
6. Using the Twin-O-Vac on high suction, suck the solution into the Twin-OVac.
7. Empty this solution and rinse the collection jar with clean water.
8. Using the Twin-O-Vac on high suction, suck the clean water into the Twin-O-Vac.
9. Empty this water and rinse the collection jar with clean water again.
10.Operate Twin-O-Vac on high suction to dry (NB => If in doubt, leave the Twin-O-Vac to dry in an aerated environment).
11.Replace the filters and prepare for normal operation.

Points of Interest

  • A good, although possibly unpleasant, way to remember which filter goes where is to think that the thick filter catches first the thick, chunky portions of fluid!!
  • Always ensure that whenever your equipment is not in use that the cylinder is closed, and the gas is drained from the regulator and Twin-OVac!
  • Please be very conscious about cross-infection risks! Always wear gloves when using or cleaning this equipment, and always throw away any  consumables, including used suction hose!
