CA 2451774

A wound treatment apparatus (10) has a vacuum bandage (28) covering a wound (22) of a patient, a vacuum source (110) coupled to the vacuum bandage (28), and a controller (20) that operates the vacuum source (110) to apply negative pressure to the wound (22) through the bandage (28) in a controlled manner. The controller (20) is programmed to limit the rate of change of the negative pressure applied to the wound (22). A caregiver has the ability to change one or more negative pressure setpoint values and the controller (20) of the wound treatment apparatus (10) controls the rate of change of the negative pressure to reduce patient discomfort.

La présente invention se rapporte à un appareil de traitement de plaies (10) comprenant un pansement sous-vide (28) appliqué sur une plaie (22) d'un patient, une source de vide (110) couplée au pansement sous-vide (28) et une unité de commande (20) qui actionne la source de vide (110) afin que soit appliquée de manière régulée une pression négative sur la plaie (22) par l'intermédiaire du pansement (28). L'unité de commande (20) est programmée de manière à limiter le rythme de changement de la pression négative appliquée à la blessure (22). Le personnel soignant a la possibilité de modifier une ou plusieurs valeurs prédéterminées de la pression négative et l'unité de commande (20) de l'appareil de traitement des plaies (10) régule le rythme de changement de la pression négative afin de réduire la gène occasionnée au patient.
