Special processes - OXIVARIO and ORTHOVARIO

Intended Use

This washer-disinfector can be set up
or retro-fitted to use the OXIVARIO
process by adding two additional
dispenser pumps together with a buffer
tank for hydrogen peroxide solution
(H O ). The DOS 2 dispenser is used
2 2
for the H O solution.
2 2
To use the ORTHOVARIO process the
DOS 4 dispensing system has to be
replaced by a dispenser pump for a
tenside based cleaning agent.
The OXIVARIO, OXIVARIO PLUS and
ORTHOVARIO programmes are
available for these requirements.
The OXIVARIO process releases active
oxygen under alkaline conditions. The
cleaning agent used must be tenside
free and have a pH value of between
11 and 11.5.
The ORTHOVARIO process uses a
special tenside based cleaning agent
in the first cleaning phase and then
releases active oxygen in the second
phase with a pH value of between 10.0
and 11.0 and a slightly higher
temperature of 65 °C.

Areas of application

The OXIVARIO procedure has an
alkaline main wash making it
particularly suitable for the
reprocessing of surgical instruments
where existing procedures are not
satisfactory.
It is particularly suitable for instruments
such as those used in high frequency
surgery, orthopaedic surgery as well as
for instruments which have dried out
because of the length of time between
using them and reprocessing them.
It is also suitable for antiseptic
circumstances.
The OXIVARIO PLUS process is
designed to prevent transmission of
iatrogenic prions (vCJD).
The cleaning processes are gentle
enough for instruments used in
minimally invasive surgery, including
fibre optics, where the manufacturer
has declared that they are suitable for
reprocessing with an alkaline cleaning
agent.
They are not suitable for anodised
aluminium.
Be aware that items made from alloys
containing titanium such as some
implants, do not always state the
material's compatibility. Reprocessing
such items can result in colour
changes, rendering any coding on
them ineffective. If in doubt please
consult the manufacturer of the item.
