Safety concept for HIDREX iontophoresis devices (special functions)

Your HIDREX iontophoresis device is equipped with several protection circuits for your safety:

Immersion monitoring

A safe­ty mon­i­tor ensures that the pow­er out­put starts slow­ly at zero and only when the cir­cuit has been closed by the skin sur­faces to be treat­ed (palms, feet, or armpits). This pre­vents unpleas­ant elec­tri­cal shocks.

Protection against excess treatment

If your skin is already dry beyond the nor­mal lev­el 1, the device will not let you raise the dose. Your HIDREX device will auto­mat­i­cal­ly check your indi­vid­ual skin con­duc­tance. If it is out­side the spec­i­fied tol­er­ance, the pro­tec­tion cir­cuit inter­venes and locks the device. Treat­ment will not start even if you close the cir­cuit.

Limiting of current

With very heavy sweat­ing (i.e. low elec­tri­cal resis­tance of the skin), the max­i­mum per­mit­ted treat­ment cur­rent can be reached before the set dose (volt­age) is reached. In this case, a pro­tec­tion cir­cuit (cur­rent lim­it) inter­venes and stops the device.

This has no effect on the suc­cess of treat­ment, but it does pro­tect you from get­ting burned!

Over time, the less you sweat, the high­er the elec­tri­cal resis­tance of the skin and the dose lev­els will slow­ly increase.
In par­tic­u­lar, in pulse cur­rent mode, this pro­tec­tion cir­cuit appears to be fast-act­ing. How­ev­er, this is not true since the device mon­i­tors the max­i­mum per­mis­si­ble cur­rent, but in pulse-cur­rent mode only an “aver­age val­ue” is gen­er­al­ly shown on the dis­play.2

Protection circuit

The device also has a safe­ty cir­cuit which stops the ther­a­py imme­di­ate­ly when a cur­rent of 35mA or more is reached (due to a mechan­i­cal or elec­tri­cal fault, for exam­ple). In this case, the dis­play will read “STOP” and all the LEDs will be flash­ing. If this hap­pens, please switch off the device, dis­con­nect it from the mains, and send it back to us.

1 This is not the water in which you are immers­ing the skin, but the mois­ture in the deep­er skin lay­ers which deter­mines the degree of hyper­hidro­sis.

2 For exam­ple, if pulse cur­rent (50% on) is used, the dis­played val­ue for cal­cu­lat­ing the cur­rent lim­it must be dou­bled.
