CANISTER, SUCTION DEVICE AND SYSTEM FOR VACUUM TREATMENT SECURING A FIXED TREATMENT PRESSURE

摘要

A canister, suction device and system for collection of effluents, in particular exudates, from a wound during vacuum treatment comprises a pump head (112) and a regulator (120) regulating the pressure in the wound (102) to secure a fixed treatment pressure. The regulator (120) may regulate the pressure by sensing the pressure in the wound and in response thereto control operation of the pump head. The regulator (120) may be permanently integrated in a housing of the canister (114) in a non-removable and/or non- accessible manner to exclude the possibility of setting adjusting the fixed treatment pressure. Air may be allowed into the wound if the pressure at the wound (102) is determined to be less than a threshold pressure.
