ASI Methods of Cleaning & Disinfecting the HVE & Saliva Ejector/Evacuation Suction Handpieces

The suction handpieces are designed for use with disposable tips which should not be reused. If using a reusable metal tip supplied by others, it must be properly sterilized before each use, according to that manufacturer’s instructions.

Barrier film is one recommended way to protect the main body of the HVE and Saliva Ejector/Micro Evacuator. If using a barrier film, the handpiece bodies should be cleaned weekly or more frequently as needed. Another recommended sterilization technique is autoclaving.

• Turn off the vacuum before disconnecting the suction handpieces.
• Remove the tip from the suction handpieces.
• Remove the HVE or saliva ejector valve/micro evacuator body from the tubing by pulling it away from the tubing to disconnect from the barb end that remains in the tubing.
• Remove the control valve spool from the main body by sliding it out from the side.
• Unscrew the nose piece from the saliva ejector/micro evacuator.
• Clean and rinse the valve body, control valve spool and nose piece using a mild detergent, water and soft bristled brushes if necessary to remove debris.
• Allow all parts of the suction handpieces to dry completely.
• Place the body, control valve spool and nose piece in a steam autoclave for at least 15 minutes at a temperature of 121(±1)° Celsius with a minimum of 15 minutes dry time.
• Apply a light coat of ASI Silicone O-Ring grease lubricant to the O-ring seals and the circumference of the control body spool and re-insert into the body of the handpiece.

CAUTION – Use only silicone lubricant when lubricating instrumentation O-rings. Petroleum products will cause permanent damage to the O-rings.

• Reattach the handpiece to the tubing barb end of the respective tubing for the handpiece.
• Operate the HVE and Saliva Ejector valves several times to verify that they rotate smoothly.
