摘要： A suction system for removal of exudate from a wound comprises a wound cover which is attachable to a wound circumference of a living being thereby to form an enclosure, and a pump in fluid communication with the enclosure to provide a pressure difference between a negative pressure in the enclosure and an air pressure of an ambient space. A deflectable member is arranged such with respect to the enclosure that the pressure difference may cause deflection of the deflectable member, and a pressure sensing device is located outside the enclosure and arranged to provide a signal in response to the pressure or the deflection of the deflectable member. The deflectable member forms an essentially air tight barrier between the sensor and the enclosure.
