Accel-Heal Solo is a wearable, simple-to-use device that delivers Accel-Heal’s innovative, single-use electrical stimulation therapy for painful and hard-to-heal wounds. It works by delivering a preset, automated programme of inherently safe sub-sensory electrical pulses to the wound. As the pulses are sub-sensory, you are unlikely to be able to feel them over the fixed 12-day period of therapy.
