4.3 PAUSE function
While the device is turned on, a short depression of the ON/OFF/PAUSE-button or pressing the turning
knob will activate the PAUSE-mode of the MultiStim SWITCH. Stimulation is stopped in this condition.
To indicate that the device is in the PAUSE-mode, the »
⫽
« or »
⬆
«-symbol will disappear and the value
of current intensity, as well as the mA-symbol will begin to fl ash up.
Important:
All stimulation parameters can be changed during the PAUSE mode without emitting stimulation
impulses to the patient. Renewed short pressing of the ON / OFF / PAUSE-button or renewed pressing
of the turning knob will end the PAUSE-mode, and the normal stimulation mode is resumed.
4.4 1 Hz/2 Hz mode
When the 1 Hz-/2 Hz button is pressed, MultiStim will generate a continuous sequence of
stimulating impulses with a constant frequency. Upon initial activation, the selected 1 Hz func-
tion is displayed on the LCD for 2 seconds instead of the impulse bandwidth indication.
Renewed pressing of the 1 Hz- / 2 Hz-button will double the pulse repetition rate to 2 Hz.
4.5 Mode cannula/KAN
MultiStim SWITCH offers the option for stimulation using an invasive stimulation cannula
(e. g. PAJUNK® UniPlex NanoLine). The puncture cannula is connected to the Y-cable by
means of the connection as provided for such. The adhesive electrode is affi xed to the surface of the
patient’s skin at an appropriate location (good contact) in order to ensure current conduction. The red
electrode clamp (positive pole, anode) is fastened to the adhesive electrode. In stimulation by means of
cannula, the current is conducted between the cannula tip (negative pole, cathode) and the red elec-
trode clamp (positive pole, anode). Pressing the »
« -button permits switching back and forth
between the cannula output and the catheter output.
If the stimulation by cannula is activated, the symbol »KAN« as well as the max. stimulation range
»6 mA« will appear. The initial intensity of the stimulation current, the stimulation frequency and the
impulse bandwidth are separately adjustable for both of the two outputs (see SETUP-functions).
4.6 Mode catheter CATH
Aside of stimulation using an invasive stimulation cannula, MultiStim SWITCH addition-
ally offers the option for stimulation by means of a catheter (e.g. PAJUNK® StimuLong).
The stimulation catheter or the catheter clamping adapter is also connected to the Y-cable over the
intermediate cable. The adhesive electrode is affi xed to the surface of the patient’s skin at an appropri-
ate location (good contact) in order to ensure current conduction. The red electrode clamp (positive
pole, anode) is fastened to the adhesive electrode.
In stimulation by means of catheter, the current is conducted between the catheter tip (negative pole,
cathode) and the red electrode clamp (positive pole).
If the stimulation by catheter is activated, the symbol »CATH« will appear as the status indicator in the
display.
The catheter can now be introduced by way of a previously positioned puncture cannula.
Please observe:
If no catheter connection cable is detected when switching to the CATH mode, i.e. the catheter is
not connected or is defective, this will cause »no« to appear on the display and an acoustic signal
may be heard; the »KANÜLE/CATH« button is without function.
If the catheter is disconnected in the »CATH« -mode, »no« will appear on the display and acoustic
warning-signals will be emitted indicating the absence of the electrode. Now:
a) the stimulation catheter may be connected again. This will cause the device to return to the original
mode,
or
b) the device may be switched to stimulation by cannula by pressing the »KANÜLE/CATH« - button.
4.7 Amplitude selection (setting of the nominal stimulation current)
The intensity of the stimulation current may be adjusted with the aid of the notched turning-knob
located in the center of the device. Turning the knob one increment to the right-hand side (i.e. clock-
wise) will increase the intensity of the stimulation current by one incremental step. Turning the knob
to the left-hand side (i.e. counter-clockwise) will reduce the intensity of the stimulation current by one
