INSTRUCTIONS FOR USE
Dear Customer,
we kindly ask you to read carefully the following instructions before handling and using our instruments.
Each MEDESY instrument has been manufactured with great care and professionalism and should be utilized by
qualified dental specialized personnel only.
FIRST USE (INITIAL USE)
The instrument is supplied ‘NON-STERILE’: it must be properly washed, rinsed and sterilized before any use. We
suggest a cleansing made by Ultrasonic-device, if not available, you may also rinse the instruments manually: use a
rigid brush with plastic bristles (NO metal bristles) and make sure that you use the proper washing and
decontamination solutions.
It is highly recommended to sterilize the instruments only after you have accurately washed them, if the instrument is
not perfectly clean, the sterilization may be prejudiced. We remind you to follow carefully the instructions for use
provided by the manufacturer of the sterilization equipment.
ADVICES FOR A PERFECT AND EFFICIENT MAINTENANCE
a. All the cleaning operations must be exclusively carried out in areas duly equipped and specifically assigned to
this purpose.
b. Instruments must be immediately disinfected after each working session, using proper solutions whose
effectiveness has been proved. Ensure that you are selecting the correct dosage of the
cleaning/decontamination solution, the right washing duration and the optimal temperature. However
always follow the instructions given by the equipment manufacturer and by the cleaning solutions producer.
c. Cleaning/disinfectant solutions containing sodium hypochlorite (NaClO) may often cause oxidation or
corrosion to the instruments, compromising seriously their performance grade.
d. Cleaning/disinfecting solutions must be changed daily.
e. The best recommended method for a proper washing of the instruments is the ultrasonic cleaning, especially
suggested for the joint instruments (ex: pliers, scissors, needle-holders, …).
f. DO NOT put aluminium instruments NOR titanium instruments in ultrasonic baths since ultrasounds may
damage both the material and the colour of the instrument.
g. For washing/sterilization do not put together in the same tray instruments made of different metals (ex:
common steel with stainless steel, aluminum, titanium, chromed steel, …).
h. For appropriate washing/disinfection all joint and hinged instruments (ex: pliers, scissors, needle-holders, …)
should be in the open position, multiple-part devices should be disassembled.
i. Make sure that trays are not overloaded with instruments since this could compromise the
washing/disinfection.
j. Possible residuals after the first rinse must be completely removed.
k. It has been proved that the ideal temperature for the final rinsing is between 80°C and 90°C.
l. It is highly recommended to use only demineralized water during the final rinsing, a precaution which
prevents the formation of dark stains.
m. To maintain the perfect efficiency of joint instruments, it is necessary to lubricate them regularly with specific
products (NEVER USE INDUSTRIAL OILS).
Autoclave sterilization by saturated steam is the most used method nowadays: steam sterilization involves the use of
steam under pressure, delivered at a particular temperature for an appropriate time. Based on heat interacting on the
thermal exchange with the instrument temperature and on the pressure, it produces an increase of the water
evaporation latent heat.
- For optimal sterilization of instruments, we suggest to proceed by means of humid heat sterilization in
an autoclave Class B. For this method of sterilization, a temperature of 134° is recommended for pressure at
2,1 bar and a temperature of 121° for pressure at 1,1 bar. For the instruments sterilized in pouches ensure
that the rinsing procedure executed before the sterilization is carefully completed by a full drying cycle, note
that water remains inside the sterilizing pouches may cause corrosion or oxidation to the instruments and
generate bacteria formation.
- Sterile products must be preserved in specific storage areas, dry and without dust.
ATTENTION:
ALUMINUM AND TITANIUM INSTRUMENTS:
Do not put aluminum instruments and titanium instruments into thermal devices and/or ultrasonic baths. For
cleansing these instruments use only substances that are specifically suggested for aluminum and titanium.
Note that some solutions are not compatible at all with aluminum nor titanium.
