In the case of nickel allergy, electrodes with aluminium tape can be ordered (single-patient electrodes). Most of the products are covered by a rental scheme for treatment devices. This means that, as a private individual, you need to contact your doctor to obtain a requisition for treatment devices. When the hospital has approved the rental, you will be able to borrow the equipment for 3-6 months. If any problems with the devices occur - technical faults, user problems, etc., you can contact Vitacon. Once you have received training in the use of your equipment from your health practitioner, you can take the device home. At the end of the rental period, you will receive a letter in the post asking you to return the device to Vitacon. A franked envelope is included with the device. Use this for returning the device. All disposable equipment such as probes and tubes can be discarded.
