Definitions

  • the system is portable since the integrated chronic wound debridement and healing system 105 may be attached to the patient 100 in a manner that allows the patient to remain ambulatory.
  • the integrated chronic wound debridement and healing system 105 may be used at home, hospitals, or other wound care facilities, for periods of several days before the dressing needs to be reapplied (e.g., throughout the duration of time when wound debridement is necessary for healing).

Abstract

Selon les modes de réalisation décrits, un ensemble accessoires de débridement débride le tissu nécrotique présent dans une plaie d'un patient et comprend ou un plusieurs accessoires de débridement, tels qu'un réseau de micro-aiguilles, des soies sensibles au pH, et un film polymère sensible au pH dans lequel est intégré un agent de débridement. Une unité de traitement des plaies par pression double (DPWT) est accouplée à l'ensemble accessoires de débridement et configurée pour appliquer par intermittence une pression positive et une pression négative à la plaie conjointement au débridement du tissu nécrotique par l'ensemble accessoires de débridement. De plus, selon les modes de réalisation décrits, une image d'une plaie d'un patient est acquise. Ensuite, une image multidimensionnelle de la plaie est générée sur la base de l'image acquise, une quantité de perfusion de plaie de la plaie est mesurée sur la base de l'image acquise en utilisant une analyse d'image en superpixels, et un histogramme basé sur la fréquence de la perfusion de plaie est généré.
