Breaking the cycle of chronic wounds

At the Welsh Wound Innovation Centre (WWIC) we are devoted to embracing new models of care to tackle the silent epidemic of wounds. In collaboration with Firstkind we have evaluated the therapeutic effect of the geko™ device on wound healing outcomes over an 8 week period.

Through a case series evaluation we have generated evidence that fills us with interest and excitement. All patients treated gained benefit from the geko™ device. Many saw a reduction in ulcer size after only a short period of therapy. Perhaps the most important observation was the notable improvement in patient quality of life and a reduction of pain1. We had not been expecting to see such a dramatic improvement using the geko™ device.

The results support use of geko™ in patients with hard-to-heal, painful venous and mixed leg ulceration, in conjunction with best practice standard care1.

Results show1:

  • Reduction in wound surface area.
  • An increased in granulation tissue formation.
  • 7% of patients with wounds of venous aetiology (VLU) achieved complete re-epithelialisation over the 8-week evaluation period.
  • 52% reported a substantial reduction in wound pain.
  • All patients reported a 100% satisfaction with the gekoTM
  • Patients reported the geko™ as easy to operate with minimal disruption to daily living.
  • Patients were enabled to self-manage the device and take control over their symptoms whilst resuming their normal daily activities.

Contrast speckle imaging data from a single WWIC case study (shown above) demonstrates a 225% increase in microcirculatory blood flow in the wound bed, and a 67% increase in microcirculatory blood flow surrounding the peri-wound area, after activation of the geko™ device. The increase in blood flow to the wound bed promotes conditions favourable to wound healing2.
