replaced between each patient.
HVE & SALIVA EJECTOR/EVACUATION SUCTION HANDPIECES
Suction Tips
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, per that manufacturer’s instructions.
High-Volume Evacuator/Saliva Ejector Handpiece Bodies
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.
To autoclave the HVE and Saliva Ejector/Micro Evacuator
1
Turn off the vacuum before disconnecting the suction handpieces.
2
Remove the tip from the suction handpieces.
3
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.
4
Remove the control valve spool from them main body by sliding out from the side (see figure).
5
Unscrew the nose piece from the saliva ejector/micro evacuator.
6
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.
7
Allow all parts of the suction handpieces to dry completely.
8
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.
9
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.
10
Reattach the handpiece to the tubing barb end of the respective tubing for the handpiece.
11
Operate the HVE and Saliva Ejector valves several times to verify that they rotate smoothly.
