CA 2634276

A suction system for removal of fluids from a surface, e.g. a wound site, the system comprising a cover (1) attachable to a circumference of the surface to form an enclosed suction space sealed from ambient space. The system further comprises a pump (4) in fluid communication with the enclosure via a tube (2) to provide a pressure difference between a suction pressure in the enclosure and an air pressure of an ambient space. To provide an improvement over the known systems and to facilitate pressure measurement, the system comprises flushing means (11) to clean the tube.

L'invention a pour objet un système d'aspiration pour l'évacuation de fluides d'une surface, p. ex. une zone de plaie. Le système comprend une coiffe qui peut être fixée à la circonférence de la surface afin de former un espace d'aspiration clos isolé de l'espace ambiant. Le système comprend également une pompe en communication fluidique avec l'espace clos par l'intermédiaire d'un tube afin de créer une différence de pression entre une pression d'aspiration dans l'espace clos et une pression de l'air dans l'espace ambiant. Afin d'améliorer les systèmes connus et de faciliter la mesure de la pression, le système comprend par ailleurs des moyens de rinçage pour nettoyer le tube.
