Intensity monitoring
During the development of the
HiToP
1touch
we have endeavored not only to offer
you a High Tone Power Therapy device of a new generation with regard to its
efficiency and operability, but also to set new standards with regard to the patient’s
safety.
The intensity is increased at open circuits
, i.e. no patient is connected to the device:
If the initial voltage is increased at open circuit and no current is measured, the circuit
will be switched off for the patient´s safety. An acoustic signal is given and the
following message will be displayed:
“Therapy terminated by open loop detection …”
!!
Note!
Please check the contact of the electrodes and the cables, resp., before
you set the intensity anew.
Abrupt resistance changes
in the electrode application could cause problems:
1.
Two electrodes touch each other and form a shunt during treatment. If the patient
moves during the therapy, that shunt can open and the patient becomes exposed to
an unintended high intensity of current.
2.
The electrodes are shorted-out by a conductive part, such as a metallic temple in
case of a tinnitus treatment. If during the treatment that shunt is removed (e.g. the
glasses are taken off) this abrupt resistance change also leads to a severe
modification of the intensity of current.
3.
Generally, please observe the notice regarding the electrode positioning
(see
chapter 5.3)
.
We at gbo Medizintechnik AG expanded the device software by a special intensity
monitoring routine in order to get the application problems mentioned under control.
This safety circuit avoids an unintended high change in the intensity of current and
switches off the circuit in such a case.
