    Our solution
    1. Working with the customer we designed the patch, running various material trials, testing different material combinations and selecting the optimum products.
    2. We designed a venting patch made up of four materials
    3. One was a Versapor micropore filter material that allows gas through but provides a barrier to liquids
    4. Two was a charcoal filter that allowed the gases to escape, removing the odour in the process
    5. Three was an EVA material placed on top of the charcoal filter, to weld to the colostomy bag and to seal the charcoal so gases escaped in our desired location
    6. Four was a double sided high performance adhesive to attach and seal the patch to the colostomy bag
    7. We designed a complex multi stage rotary process, combined with our AccuPlace automated pick and place equipment to assemble the pre-converted charcoal discs to the Versapor filter.
    8. The design also incorporated a dry tab for ease of application for the customer’s assembly process
