VI. Cleaning and Sterilization
In this section we describe the procedures to clean and sterilize the scaler. It is
important to follow these procedures before using the machine, otherwise, patients
and/or doctors may have the possibility of getting infection.
It is mandatory
that doctors wear sterilized gloves during these procedures at all time to avoid
any possibilities of incomplete sterilization and/or infection.
Below we detail
the infection control procedures for the Handpiece, the Tip, and the Main Unit,
respectively.
Handpiece
Before cleaning, remove the Tip from the Handpiece. Let the Handpiece run
for a couple of seconds to drain out the water and any possible contamination
left inside the Handpiece. The outer surface of the handpiece should be
cleaned with anantiseptic soap or solution. Rinsed off with water and wiped or
sprayed with a chemical disinfectant that is compatible with the handpiece
material, such as a 1:6 dilute solution of Sporicidin brand disinfectant. A
sterile insert or TIP is then reassembled to the handpiece in preparation for the
next patient.
Warning
:
Do not put the Handpiece and the extension wire directly into
the sterilized fluid. Any left such fluid inside the machine
will interfere with the normal operations of the system.
At the end of the day with the Tip remove, the handpiece and cable should be
scrubbed with an antiseptic soap or solution and rinsed off with water. The
handpiece should be scrubbed a second time with an antiseptic soap or
solution and rinsed off with water.
Warning:
The chemical disinfectant should not be allowed to remain on
the surface longer than the recommended time or material
damage may result.
Note
:
Cleaning of the Hand-piece is suggested after each patient use.
Tip
After each usage, there will be saliva and/or blood or other debris left on the
Tip, consequently, it is necessary to clean the Tip with a supersonic cleaner
first. This can be done manually by scrubbing with a brush or by use of an
ultrasonic cleaner with a solution of detergent and water. After scrubbing. The
Tip should be rinsed thoroughly with water to remove all detergent. Then dry
the rinsed Tip. Finally, put the Tip in a bag and then put it into a medical-
equipment autoclave and sterilize the Tips at 260
℉
(127
℃
) for 30 minutes or
as recommended by the manufacturer of the particular sterilizer used.
An alternative, but less desirable method of sterilization is the use of a
compatible chemical sterilant such as Sporicidin brand disinfectant. In this
method, the Tips is immersed at room conditions in the disinfectant at the
appropriate strength and for the recommended period by the manufacturer. The
thoroughly rinsed with sterile water and completely dried.
