handpieces and compressors Flashcards
why is handpiece maintenance important?
- Practice is responsible for procurement
- Handpiece costs £200-1000
- Required routinely
- Infection prevention and limiting cross contamination
- Standardised maintenance process to achieve standard
- Compliant decontamination process to achieve standard
when should the handpiece be cleaned and how?
- After every patient use, cleaning should take place
- Manual cleaning is the first step
- The cleaning cycle should be carried out in a washer disinfector that meets requirement
- The hand piece should be lubricated after wash and before sterilisation
- A steriliser with vacuum capability is necessary for adequate air removal
ULTRASONIC BATHS ARE NEVER USED
MANUFACTURERS INSTRUCTIONS SHOULD ALWAYS BE TAKEN INTO ACCOUNT
ANNUAL MAINTENANCE IS NECESSARY TO VERIFY CORRECT OPERATION
top 5 causes of handpience faults
5 - Incorrect compressor settings and lack of maintenance
4 - Damaged or oversized bur fitted
3 - Incorrect instrument usage
2 - Poor or inadequate cleaning, including, incorrect processing
1 - Incorrect or inadequate lubrication
how to avoid Incorrect compressor settings and lack of maintenance of handpieces
Medical/Dental grade compressor is essential
Incorrect air pressure causes faulty operation
Maintenance is essential
Pressure Vessels, like Sterilizers and compressors, must be inspected annually. (Pressure Systems Safety Regulations 2000)
oversize or damaged bur used in handpieces
effect
mainly oral surgery
damages chuck - cannot remove bur or bur sticks, may not be able to hold burs
incorrect handpiece use can be
wrong instrument being used for procedure
or handpieces being used for something not intended to be used for
poor or inadequate cleaning of handpieces can be due to….
3
or incorrect processing of handpieces
- Disassembly vs no disassembly
- Sterilisation temperature
- Ultrasonic baths – do not put in
4 key things to remember when processing handpieces
Will need to be processed in washer-disinfector. Not always suitable so check recommendations
Must be lubricated after every use
Must be Sterilized after every use
Service handpieces every year!
5 stages in WD
A cold prewash
A heated detergent wash
Pure water rinse to remove residue
Pure water thermal disinfection
Drying phase
2 key stages of lubrication
Cleaning and flushing through the spray air channels
* prevents build-up of scale
* keeps the fine spray nozzles free
Automatic oil dispensing system
* guarantee optimum lubrication
* no excess oil
oil in lubrication
always use manufacturers recommended oil as it is water soluble and food grade
water lines for lubrication
poorly looked after water and air lines can contaminate handpieces.
Also put aerosols of contamination into local atmosphere.
how to use Assistine lubrication system
Rotational lubrication, of the spray tubes, flushing through with compressed air, in only 35secs
- Connect the instruments and close the cover
- Starting the maintenance programme which runs automatically
- After 35secs you have perfectly maintained instrument
specifics of sterilisation
5
- A vacuum cycle is recommended
- Air has to be removed from the chamber
- Steam is introduced
- 134-137 degrees
- Steam is removed/vented**
traditional air compressor
oil lubricated
Traditional oil-lubricated compressors need frequent attention
That includes the need to check oil-levels in the pumps as well as having to drain moisture and emulsified oil from the receiver.
* This should be done at least weekly, and can be a smelly and dirty procedure.
