Abstract

The invention relates to a flexible application aid for the treatment of wounds. The application aid can be used in particular for the debridement and/or cleansing of wounds, including the skin surrounding the wound. The application aid according to the invention including a flexible or elastically deformable application wand, facilitates debridement of superficial to deep wounds without the risk of injury to the wound.

         5 . The application aid according to  claim 1 , characterized in that a bending force of between approximately 60 Newton (N) and approximately 15 N acting on the application wand perpendicular to its longitudinal direction results in a flexural elongation of approximately 5%. 
     
     
         6 . The application wand according to  claim 5 , where the flexural elongation of approximately 5% results from a bending force of between 21 N and approximately 33 N. 
     
     
         7 . The application aid according to  claim 1 , characterized in that the application wand is deflected by 5 mm to 8 mm when a bending force of between 21 N and 45 N is applied to the bending section perpendicular to the longitudinal direction of the application wand, the bending force applied using a 3 point bending device having two supports and a span between the supports, where the length of span between supports is between 40 mm and 60 mm. 
     
     
         8 . The application aid according to  claim 1 , characterized in that the application wand has an elongation at break of between 6% and 50%. 
     
     
         9 . The application aid according to  claim 8 , where the application wand has an elongation at break of 16%. 
     
     
         10 . The application aid according to  claim 1 , characterized in that the application wand resists breaking when a bending force is applied to the bending section perpendicular to the longitudinal direction of the application wand causing a deflection of the application wand of up to 20 mm, the bending force applied using a 3 point bending device having two supports and a span between the supports, where the length of span between supports is between 40 mm and 60 mm. 
     
     
         11 . The application aid according to  claim 2 , wherein said synthetic fibers have a fiber strength of between 0.5 dtex and 20 dtex. 
     
     
         12 . The application aid according to  claim 1 , characterized in that the fiber wound cleansing pad or wipe comprises at least one support layer and threads arranged on the support layer, the threads projecting longitudinally from the support layer to form a pile with a pile height of between 3 mm and 30 mm, at least some of the threads comprising ends or end faces extending away from the support layer at an angle to their longitudinal projection. 
     
     
         13 . The application aid according to  claim 12 , where the ends or end faces of the threads are cut off. 
     
     
         14 . The application aid according to  claim 2 , characterized in that the wound cleansing head completely encircles or envelopes the fastening section of the application wand. 
     
     
         15 . The application aid according to  claim 2 , where the force required to remove the wound cleansing head from the fastening section in the direction of the longitudinal direction of the application wand is more than 25 N. 
     
     
         16 . The application aid according to  claim 15 , where the force required to remove the wound cleansing head from the fastening section in the direction of the longitudinal direction of the application wand is 70 N or more. 
     
     
         17 . The application aid according to  claim 2 , characterized in that the wound cleansing head comprises a lower edge facing the grasping handle section and a front edge opposite the lower edge of the wound cleansing head, the lower edge comprising a reach-through opening to facilitate insertion of the application wand into the wound cleansing head, and the fastening section of the application wand comprises projections that help keep the inserted application wand from sliding back through the reach-through opening.
