The innovation of the WMCS technology is the wireless delivery of Electric Stimulation which enjoys very high evidence classes.
Market introduction: October 2015
The Wetling W200 is an electrical device that operates based on the Wireless Micro Current Stimulation (WMCS) technology for wound healing. This innovative WMCS technology is invented based on the well-known and scientifically verified Electrical Stimulation (ES) method for wound healing whereby it enables the ES to be wirelessly transferred to the wound based on the ability of nitrogen and oxygen to accept or donate electrons. The WMCS turns atmospheric gases (either oxygen or nitrogen) to ions and sprays them onto the receiving tissue, while an adjustable flexible bracelet (neutral electrode) worn around a healthy wrist or ankle of the patient closes the circuit with no physical contact to the wound.
Principles of Operation or Mode of Action
The recognition of bioelectricity’s role in tissue healing provides a rationale for the therapeutic application of electrical stimulation (ES), particularly in cases where natural repair processes have paused. There is a considerable and growing body of evidence in the last decade on the indication of ES in wound healing. ES works by mimicking the natural “current of injury” which occurs in the injured skin. It enhances the healing process by: a) increasing blood flow and oxygen uptake around wounded cells, b) directing cell migration and other components of the extracellular matrix, c) stimulating the growth of granulating tissues with an additional bactericidal effect. The usual principle for ES implementation is to transfer the current through surface electrode pads that are in wet electrolytic contact with both the external skin surface and the wound bed. Despite the beneficial effects on the healing rate of chronic wounds, this method has not been widely adopted, due to disadvantages related with the positioning of the electrodes at the tissue next to the wound area. As a result of this contact, increased risk of infection and pain to the patient has been reported. Wireless Micro Current Stimulation (WMCS) is an innovative, non-invasive technology to transfer current wirelessly to a surface wound site; it disposes of contact electrodes and thus solves the major issue of infection risk during therapeutic sessions in extended and deep wounds, burns and ulcers, while also tackling the just as important one of pain and discomfort. The WMCS turns atmospheric gases (either Oxygen or Nitrogen) to ions and sprays them onto the receiving tissue, while an adjustable flexible bracelet (neutral electrode), worn around a healthy wrist or ankle of the subject, closes the circuit with no physical contact to the wound. With this spray effect, it offers a radical advantage compared to other currently used ES techniques.
