Composition And Characteristics; Operating Instructions - Medela Invia White Foam NPWT Mode D'emploi

Composition and characteristics

The Invia White Foam is made from 100% polyvinyl alcohol.
The Invia White Foam is a hydrophilic, enormously absorbent foam. This means it is ideal
for the effective removal of wound exudate and tissue fragments.
Combined with the Invia Negative Pressure Wound (NPWT) Therapy Systems with negative
pressure levels between 80 mmHg and 150 mmHg, Invia White Foam ensures reliable re-
moval of wound exudate from the wound. The applied negative pressure is distributed
evenly on the base of the wound.
An intact sealing system guarantees a reliable airtight closure of the wound and thus an
optimal use of negative pressure and exudate transport.

Operating instructions

– Invia White Foam must only be used by medical and nursing staff.
– Take Invia White Foam from undamaged packaging.

White Foam comes in close contact with (parts of) blood vessels, tendons, nerves and
other vulnerable vital organs and tissues.
– Always look for unexpected blood loss and instruct the patient accordingly.
– In the treatment of sternum wounds, controlling the blood pressure and ventilation
is mandatory.
