What type of wound can it help heal?
The W250 can be applied to most wounds:
- Infected wounds
- Non healing wounds
- Chronic wounds
- Diabetic leg and foot ulcers
- Post-surgical wounds (infected)
- Pressure ulcers ('bedsores')
- Arterial ulcers
- Venous stasis ulcers*
- Trauma wounds (protection, sterilization)
- Necrotizing soft tissue infections

World First SIS Stimulation Pads
- Pads do not contact the wound. No disturbance of new granulation tissue formation.
- Can be used together with standard wound dressings. Can also be used completely standalone if necessary or advantageous.
- No discomfort. Maximum skin protection. SIS ultra-low voltage stimulation technology.
- Continuous ultra-precise electrical stimulation transmission to the wound from the W250 machine.
- Highest conducting electrotherapy pads in the world. Up to 200× better than standard self-adhesive electrotherapy pads.
Feedback from users of the W250 machine
I had a large post-op wound infection. I used the SIS machine W250 and symptoms disappeared within days. I have also used the machine instead of antibiotics for puncture wounds. We would not be without this machine, it is the best First Aid kit I have ever seen.
EmmaNurse In 2016 I had two serious wounds on my lower right leg, 7cm by 3.25cm, and 3.5cm diameter, following a bout of septicaemia. The wound on the back of the heel was so deep that the tendon was exposed and a skin graft was recommended. After two weeks the tendon responded to healing [stimulation] and covered itself naturally and my next visit to the surgeon showed him there was no need for any surgical intervention such was the improvement. The Silver Chain home care nurses repeatedly expressed their amazement as to the speed such serious wounds have healed. The SIS device monitored the wounds and provided a healing without any side effects.
DomonicOutpatient A ladder broke under me and as I fell I tore a large lump of flesh from the front of my right leg. First Aid and a bandage seemed to suffice but within the next few days the wound became seriously septic. The hospital doctor urged me to take IV antibiotics to counter the infection. I used the SIS machine to reduce the infection and overnight the injury was cleared of infection and by week's end the injury was sealed and today there is little sign of the injury on my leg.

The Benefits of SIS Technology
Electrical Stimulation Device
Treatment and prevention of infection. Ultra precise, microorganism-specific, low intensity direct current. Effective for antibiotic resistant superbug infections.
Wound healing. Realtime, self-adaptive supplementation or replacement of the key bioelectric controller of wound healing: the wound-generated electric field—boosts the body’s natural ‘current of injury’.
Better healing, less scar tissue. Stimulates fibroblast cells in the wound to self-modify to have tissue regeneration abilities resembling stem cells potentials.
SIS electrodes do not contact wound. No disturbance of new granulation tissue growth during wound closure; no added wound discomfort.
Suitable for most types of surface wounds and ulcers.
No drug side effects or risks.
Quick and easy to apply. For independent home and clinic use.
Robust construction inside and out. Medical electronics standard certified. Each unit is a precision instrument, individually tested and calibrated by our engineers. 5 year warranty.
