cup after each use. Use fresh medication each time you use the
device.
After cleaning, all attachments must be dried and then stored in a
clean place.
Do not store the air tube when there is moisture or medication
residue inside.
Disinfection
Make sure the parts after each use are disinfected. If pollution is
serious, please replace parts with new ones timely. There are two
disinfection methods:
1) Use a commercially available disinfectant. Please follow
the instructions provided by the disinfectant manufacturer.
a) Disinfectant soaking should be in accordance with the time
required in the instruction manual of disinfectant.
Rinse with clean warm water and allow to air dry in a clean
environment.
Caution:
After the nebulizer kit are removed from the disinfectant,
according to instructions on disinfectant, sufficiently wash the
units with clean water, and take care to avoid residual disinfectant
for disinfectant inhalation may cause worsening of symptoms.
If colored disinfectants (such as chlorhexidine) are used, after a
long time using, there may be different color changes of units.
This is not a problem on the physical properties. When color
change is serious, please purchase separately sold items to
replace.
2) Add enough water in the container, put parts that can be
sterilized by boiling, heat up to boiling for 15 to 20 minutes. After
boiling, carefully take out the units, shake off excess water and
allow to dry in a clean environment.
Caution:
Do not cook the air tube, mask, filter, filter cover and accessories
in boiling water or use boiling water to wash to prevent heat
deformation.
In the disinfection process, please ensure the medication cup is
empty.
When sterilized by boiling, be careful not to burn without water.
