Structure & Working Principle
Main Technical Performances
1. High negative pressure, High flow
2. Power Supply: □AC220V □AC230V □AC240 □50HZ □60HZ
3. Input power: 150VA
4. Limit negative pressure: ≥0.08MPa(760mmHg)
Oil free lubrication pump to keep the environment from being polluted by the
oil mist.
Low noise.
Round negative pressure meter, and plastic cover.
No any positive pressure to be generated during running, to ensure reliable
and safe operation.
Negative pressure regulating system can be adjusted steplessly.
Small in size, light in weight and portable.
The operating principle diagram shown as follows:
Portable phlegm suction unit is based on similar products at home and
abroad is a new generation of oil free lubrication suction device, which is
suitable to use by the patient who has difficulty in phlegm removal due to
illness, coma and operation, as well as for aspirating such liquid as pus and
blood during the clinical practice. It is the commonly applied medical device
in the emergency room, operation room, and for nursing in sickroom and
home health care.

Product Features
Installing and Commissioning
The customer shall carefully inspect if the appearance of product is good,
and the varieties & quantities of the attachments are in conformity with
those as indicated in the attached list before installing and commissioning.
Also, the customer shall timely notify the supplier or manufacturer of
damage(s) if any.
Note: Apply small amount of distilled water
around the part (pressed into the holder
mouth) of holder plug during installing,
which is good for tightly pressing the
holder plug and enhancing its sealing.
